Sweet sorghum (Sorghum dochna L.) restorer lines effects on nutritional parameters of stalk juice
51-56Views:136Sweet sorghum can be utilized for bioethanol production because it has high sugar content (14-17%). We determined the most important nutritional values of 5 silo type sorghum lines in waxy and full maturation. The examined restorer lines were: RL 4, RL 9, RL 15, RL 18, K 1. The following nutritional parameters were examined: dry material content, refractometric total sugar content, reducing sugar content. In waxy maturation 73.85-87.37% of dry matter in stalk juice makes the total sugar. Dry material content, total and reducing sugar content of stalk
decreases from waxy mature to full maturation.
There are differences between lines in dry matter (SzD5%=0.76), total sugar (SzD5%=0.79), reducing sugar content (SzD5%=0.30). RL 4 performed a decrease in total sugar content from 10.07% to 10.02% during this period, reducing sugar also decreased from 4.01% to 2.47%. RL 9 performed a decrease in total sugar content from 11.76% to 11.08% during this period. Reducing sugar also decreased from 3.17% to 2.01% in the waxy
maturation. RL 15 showed a total sugar content decrease from 15.43 % to 15.36%. The reducing sugar also decreased from 3.23% to 1.71% in waxy maturation. In RL 18 total mean sugar content during waxy maturation was 13.78% which dropped to 13.26% approaching full maturation. Reducing sugar also decreased from 4.11% to 2.23% in waxy mature. K 1 performed a decrease in total sugar content from 9.35% to 6.15% during this period, while reducing sugar also decreased from 1.52% to 0.77%.
These lines upcoming for experiments are perspectives since having excellent stalk juice nutritional parameters they are of great or very great height and their stalks are thick-very thick, stalk medullas are wet. -
Nutritional disorders of arable crop growth in eastern Croatia
273-290Views:140Nutritional imbalances accompanied with growth retardation of crops at early growth stage were found since the last 40 years on certain arable lands in eastern Croatia. In this regard, phosphorus (P) deficiencies in maize and wheat were found mainly on acid soils of the western part of the region, potassium (K) deficiencies in maize, soybean on the hydromorphic neutral to alkaline calcaric drained gleysols of Sava valley lowland, while zinc (Zn) deficiencies were observed mainly in seed-maize and soybean on neutral calcaric eutric cambisols of the eastern part of the region. Cold and moist spring is factor promoting P deficiency symptoms. As oasis of normal crops existed on same arable land, comparison of plant and soil composition was possible from typical sites. P nutrition disorders were in connection with the lower P and the higher aluminum (Al) and iron (Fe) concentrations in the top of plants and the lower soil pH values. K-deficiency as result of strong K fixation and imbalances with high levels of magnesium (Mg) were the main responsible factors of low maize and soybean yields on some drained gleysols. Chlorosis incidences typical for Zn deficiency in maize and soybean were in close connection with the higher soil pH, the lower quantities of mobile Zn, here and there the higher mobile P in soil, the lower concentrations of Zn and the higher levels of Al and Fe in plants. Overcoming the above mentioned disorders and normalization of yields were achieved using ameliorative fertilization either by K or P fertilizers and in case of Zn by foliar spraying of crops with 0.75% ZnSO4 solution. Also, alleviations are possible by selection of more tolerant genotypes of field crops to specific types of nutritional disorders. From this aspect, some practical solutions were recommended for maize with reference to K nutritional problems.

Insect base-protein: A new opportunity in animal nutrition
129-138Views:491The consumption of insect protein, as well as its use in animal feeding, has become a trend. This trend is particularly receiving a lot of attention in animal nutrition because the current protein source of the highest quality in animal feeding which is fishmeal is unsustainable, expensive and its demand is higher than supply. Insect protein can be of great potential in combating world hunger as the world population continues to increase. The potential of insect protein is wide-ranging, it could improve the economics of feed production, lead to cleaner production due to its low environmental footprint.
This review focuses on the need, (nutritional and environmental) advantages of insect protein in feed production, as well as previous research findings.
The unanimous conclusion of the reviewed papers is that insect protein has a great potential in feed production in terms of nutritional value, environmental implication, sustainability as well as economic implication.
However, there is a need for the intensification of research on this alternative protein source in Europe, especially in aquaculture due to the approval of 7 insect species in aquafeeds by the European Union. Another reason for the intensification is that there is still much to be done as a result of past research which shows that growth effects vary based on species and inclusion level.

The change of the inner content parameters of table beet (Beta vulgaris L. ssp. esculenta Gurke var. rubra L.) as a result of storage
113-119Views:191The stored vegetables play a key role in the vegetable consumption. After harvesting, the storage conditions greatly affect nutritional parameters of the crop. The red beet is a root vegetable, which is manufactured mainly fresh in our county, therefore we do not have enough information about the storage. In our experiment, 5 varieties (Rubin, Akela, Larka, Libero, Mona Lisa) were examined in prismatic structure (0–5 °C and 95–97% RH) through 5 mounths.
Our measurements proved that under the appropriate storage conditions water loss was also occurs, which increased the dry matter content (average of 0.5 g 100 g-1). The bioactive compounds, like pigments (betanine and vulgaxanthin) and the quantity of flavonoids, were significantly increased during the experiment.
The results showed that the nutritional parameters of the 5 types was positive during the prismatic structure. However, this storage method negatively affected the bioactive compounds of the Akela genotype. Further studies are recommended for proper storage parameter adjustment, which is justified by the need of the different varieties. The optimal conditions enable us to preserve and to increase the best nutritional index.

Opportunities for improving the nutritional value of cereal-based products
275-278Views:221We set up experiments for improving the nutritional value of cerealbased products. Our aims were to decrease the energy content of bakery products with the mixing of plant originated raw materials and byproducts with high fibre contents, and we have evaluated the effect of sodium-chloride on the physical properties of bakery products. We found that the apple pomace, the byproduct of juice production, is excellent for increasing of fibre content of bakery products and the further aim of investigation is to develop economical ways of hygienic byproduct handling and purification. Our experiments, evaluate the bakery use of triticale, have significant achievements and the breads made from triticale flour and whole-grain are commercially available nowadays. Our investigations included the possibilities of decrease of toxin contamination of cereals and our results can form a part of risk estimation systems after further experiments .

Review on the fatty acid profile and free fatty acid of common carp (Cyprinus carpio)
99-105Views:112Carp or ponty in Hungarian, is considered commercial freshwater fish, which is an adaptable species in both wild and cultured conditions. Carp has high nutritional value content, favorable taste, it is rich in protein, and low in saturated fat. The nutritional content in fish is composed of many chemical constituents and influenced by many factors. One of the components that its content may be different due to internal and external factors is fatty acids, which may vary depending on endogenous and exogenous factors. The endogenous or internal factors include the genetic, size, sexual maturity, and life cycle phase. While microclimate, water quality, quality of food or diet habit, and the amount of available food or starvation are considered as exogenous or environmental factors. Freshwater fish has the ability to convert essential fatty acid into long chain polyunsaturated fatty acid like AA, EPA, and DHA. Most results showed that palmitic acid and oleic acid were the dominant SFA and MUFA in carp both for wild and farmed carp in all seasons. The PUFA for wild carp was mainly dominated by DHA, while on farmed carp by LA. It confirmed that high LA content in farmed carp was related to the diet habit. The amount of lipid and FA were changed in line with the season. Even the statistical analysis showed no significant difference, but some studies showed a contrasting result. Moreover, most obtained results acknowledged that FA tends to decrease during the spawning period. The amount and composition of FA were affected by the total lipid content. The lipid must be broken down into simpler compounds such as FA or FFA for the metabolism of fish. The result of metabolism then transported into the utilising tissue and used as energy.

Studies on Ostrich (Struthio Camelus) - Review
15-22Views:1013Ostrich has been reared in Hungary for decades, but we have limited information on this species. The aim of this review was to provide a concise description of the ostrich (Struthio camelus) based on international studies. We were to investigate some of the most relevant parameters, such as egg, meat and skin production. In this critical review we managed to sum up the most significant features and productivity parameters of ostrich and effecting factors. So as to make an accurate description of the species we have to know its morphological, behavioural and physiological characteristics. Ostrich is a very special bird with special nutritional and environmental requirements. Ostrich products, regarding egg, meat and skin are considered luxury products not only in Hungary but also abroad. Though egg has a significant nutritional value, it is mainly used for hatching chicks. In Europe we can expect roughly 40–50 eggs from a hen yearly. Ostrich has a lean meat with high protein and low fat and sodium content, moreover it is rich in minerals and polyunsaturated fatty acids. Having these advantageous qualities, ostrich meat should be part of our healthy diet. Skin production is not important in our country, but there is a special demand for high quality ostrich leather globally. In the future our aim is to conduct a research on some of the parameters. As low production rate and embryo mortality is a great deal of problem in ostrich industry, we need to investigate the incubation environment. There is an apparent disagreement among researchers on optimal slaughter age. This is also an area for further investigation. The value of skin and effecting factors on our climate as well as adaptability of the species are also worth for further investigation together with the nutrition what differs from other ostrich breeding countries. Nowadays, there is a great emphasis placed on animal welfare too.

The variation of breast milk composition during the lactation stage for mothers from the Csík region
93-98Views:95The aim of our research was the examination of breast-milk composition from mothers living in the Csík region and to follow their milk composition variations during lactation. In this article we present the results obtained from three mothers, paying particular attention to essential components. The breast milk samples were collected from healthy mothers with similar habits and age. The milk samples were collected with a hand pump at the
same time after the feeding. The sampling period was from day 5 to the 14th weeks of lactation. The nutrition of mothers was recorded on a questionnaire, completed by the mothers themselves. Comparing our experimental results with data in the literature it was concluded that the milk protein content was very similar to the milk of mothers from other European countries, and is decreased during lactation.
The total saturated fatty acid content was lower, but the palmitic acid content was slightly higher. Regarding the essential fatty acid composition the linoleic- and the arachidonic acid contents were appropriate from a nutritional point of view. The linolenic acid was present in lower amounts, but the docosahexanoic acid was almost undetectable.
The iron and manganese contents were in good agreemen with published results, but the zinc content of the breast milk was lower and its copper content was higher. These differences in milk composition can be explained by the different nutritional habits of our subjects. -
Harnessing diversity in durum wheat (Triticum turgidum L.) to enhance climate resilience and micronutrient concentration through genetic and agronomic biofortification
9-20Views:185Huge consumption of wheat-driven food products with low bioavailability and small concentrations of zinc is responsible for zinc-induced malnutrition and associated health complications. The contemporary durum wheat varieties have inherently tiny zinc concentrations in developing grain, which cannot meet the daily human zinc demand. Despite the fact that over two billion people are suffering from iron and zinc-induced malnutrition, various intervention measures have been deployed to reverse the effect of zinc-induced malnutrition on humans. There are evidences that agronomic and genetic biofortification approaches can increase grain yield and nutritional quality (i.e. zinc, iron, protein, and vitamins) of durum wheat to a greater extent. However, there is a lack of direct empirical evidence for which the influence of both biofortification approaches on improving human health. Application of micronutrient-containing fertilizers either in the soil or foliarly is effective in combination with NPK, organic fertilizers coupled with efficient durum wheat varieties, emphasizing the need for integrated soil fertility management (ISFM). Although genetic biofortification is a cost-effective and sustainable approach, agronomic biofortification provides an immediate and effective route to enhancing micronutrient concentrations in durum wheat grain. The application of zinc-containing fertilizers is more effective under drought conditions than in normal growing situations. Hence, this article provides a key information for agronomists and breeders about the potential of biofortification interventions to improve durum wheat yield and enrich the grain qualitative traits to ensure food and nutritional security of the ever-increasing world population.

Study of traditional folk foods from the point of view of nutrition in Hajdú-Bihar County
47-51Views:110Healthy nutrition is one of the major topics of our days. The occurrence of the so called “civilization diseases” is increasing continuously as a result of the changes in our nutritional habits and life-style. It was thought that folk nutrition at the beginning of the 19. Century had several beneficial effects on health. For this reason it was decided to study the food and nutritional habits of the population of Hajdu-Bihar County around the 1930s on the
basis of literary sources to see how well they do match with modern requirements of healthy nutrition. -
Analysis of sweet corn nutritional values using multivariate statistical methods
103-108Views:240Processing large amounts of data provided by automated analytical equipment requires carefulness. Most mathematical and statistical methods have strict application conditions. Most of these methods are based on eigenvalue calculations and require variables to be correlated in groups. If this condition is not met, the most popular multivariate methods cannot be used. The best procedure for such testing is the Kaiser-Meyer-Olkin test for Sampling Adequacy. Two databases were examined using the KMO test. One of them resulted from the sweet corn measured in the scone of the study, while the other from the 1979 book of János Sváb. For both databases, MSA (measures sampling adequacy) was well below the critical value, thus they are not suitable e.g. for principal component analysis. In both databases, the values of the partial correlation coefficients were much higher than Pearson’s correlation coefficients. Often the signs of partial coefficients did not match the signs of linear correlation coefficients. One of the main reasons for this is that the correlation between the variables is non-linear. Another reason is that control variables have a non-linear effect on a given variable. In such cases, classical methods should be disregarded and expert models better suited to the problem should be chosen in order to analyse the correlation system.

The parameters of homemade jams after storage
39-42Views:150Nowadays producing jams is considered a traditional way of plum processing in Hungary. Plum jams without added sugar can be stored
This research aimed to analytically determine which quality parameters of the jams and to what extent they change during storage. Furthermore, this study intended to find out whether a concious consumer can presume any difference between varieties or the year of harvest, or wheather a one-time customer should suspect differences in quality parameters of the different products. This study focused on those differences or alterations in the parameters that occur in the jams made from several different plum varieties produced in different years.
I analyzed the classic chemical parameters (dry matter content and ash content) and physiologically important nutritional components (phenolic and flavonoids antioxidants and vitamin C). In this research I used jams which were produced from 6 varieties grown in 2009 (President, Tophit, Bluefre, Elena, Presenta, Stanley), 4 varieties from 2010 (President, Bluefre, Elena, Presenta) and 6 varieties from 2011 (President, Tophit, Bluefre, Elena, Presenta, Stanley). Jams were produced with traditional technology in cauldrons without added sugar. Jars were placed into a relatively dark and cool place and were stored there until the analysis.
Having regard to the results, when consumers choose between the different products they also choose quality since the processed plum variety, and the year of production/processing determine the nutritional value of the specific product. This could be used for market positioning and promotion of the product, however further research is needed to gain more information from the differences that derive from the varieties, year of harvest or other factors. This way fruit and jam producers could turn these informations into market advantage.

Scientific background of precision animal nutrition
95-99Views:110Precision animal nutrition consists of meeting the nutrient requirements of animals as accurately as possible in the interest of a safe, high-quality and efficient production, besides ensuring the lowest possible load on the environment. This is facilitated by electronic feeding based on IT technology, an important but by far not the only tool of precision nutrition. In the present paper the following most important elements of precision nutrition are discussed: diet formulation, quality control of ingredients and compound feeds, reduction of the harmful effects of heat stress in pigs with different nutritional tools, application of the recent findings of the molecular genetics in animal nutrition, the relationship between genetics and animal nutrition and reduction of the N and P excretion by nutritional tools.

Evaluation of blue and red corn landraces
239-243Views:91Corn breeding can be successful only on a broad base of genetic material. The expansion of breeding aims includes the research of germplasm materials. In our experiments, we examined 11 blue, purple and red exotic corn varieties on two locations in Hungary. We conducted a complex study to obtain more information. We studied several morphological and phenological features and determined the most important qualitative parameters (protein, fat, ash). We applied the Tassel Area Index (TAI) under Hungarian conditions and compared it with the pollen producing ability of different genotypes. Results show that there are great opportunities in exotic corn varieties. Their quality exceeds that of the yellow ones in many cases. There are significant differences in yield and nutritional parameters. The favorable nutritional composition is not coupled with great productivity. Based on their flowering time and their agronomical features, they can be cultivated under Hungarian conditions as well. They match the new breeding aims, so they can be used as functional food or energy plants. With their high pollen producing ability and TAI, they can be utilized as markers in future pollen research.

The effect of herbs on the microbiological stability and nutritional quality of pariser
101-104Views:93The purpose of this study was to evaluate the functional properties of dried herbs (Thymus vulgaris L., Origanum vulgare L., Salvia officinalis L.) to improve the quality characteristics and microbiological stability of Hungarian meat product, pariser. The addition of herbs did not affect the microbial properties of the product. According to the Decree No. 4 of 1998 of the Ministry of Health, pariser can be considered safe. The nutritional quality of the different forms of pariser was also acceptable. However, the addition of oregano, sage and thyme changed the flavor characteristics of the parisers and the higher meat content would increase the final price of the product.

Effect of different N doses on maize yield and quality
97-101Views:164The effect of N doses on the yield and nutritional values of the Sushi (FAO 340) maize hybrid were analysed in three years (2018, 2019, and 2020). The analyses were performed at the Látókép Experimental Station of the University of Debrecen on calcareous chernozem soil, in a striped, small-plot, non-irrigated long-term field experiment. In the experiment, in addition to the non-fertilized treatment (A0), the N-fertilizer doses were applied as basic fertilizer and top dressing. The 60 and 120 kg N ha-1 dose (A60, A120) applied as spring basic fertilizer were followed by two phases of top-dressing in V6 (V690, V6120) and V12 (V12150, V12180) phenophases; the amounts were +30 and +30 kg N ha-1.
Maize yields were affected to varying degrees by crop year. The highest yields in 2018 and 2020 were recorded in the same V6150 treatment, while in 2019 the highest yield was obtained in the A120 treatment.
Increasing the N doses resulted in an increase in the protein content of the maize kernel. Depending on the fertilizer treatments and the crop year effect, the protein content of maize kernels varied between 6.2–10.2 g x 100 g-1. In all three years, the protein content was the lowest in the control treatment (A0) and the highest in the V6150 treatment.
The starch content ranged from 70.7 to 77.9 g x 100 g-1 in the average of the three years. In 2020, it was significantly higher in all nutrient treatments than in the other examined two years. The highest starch content - except for 2020 (A120, 77.9 g x 100 g-1) - was recorded in the A0 treatment (74.2, 72.3 g x 100 g-1).
The oil content of maize kernels varied between the values of 3.8 and 5.2 g x 100 g-1 in the average of three years. In terms of oil content, the results for 2018 and 2019 can be considered the same, while in 2020 it was significantly lower. Fertilizer treatments did not significantly affect the oil content of maize in any of the years.
The fertilizer dose applied in the V12 phenological phase was not effective in terms of yield and nutritional content (protein, starch and oil content).

The toxicity of different selenium forms and compounds – Review
33-38Views:1996Selenium (Se) is an unusual metalloid of considerable interest from both a toxicological and a nutritional perspective, with a very narrow safe range of intake. Although there are many reports about its detoxification properties, toxicity aspects of it have also been tracked for several decades. Lots of studies demonstrated that low Se is an efficacious avail whereas high Se can induce toxicity and the significant toxicity of selenium emphasizes the need to assess the health risk of various selenocompounds as nutritional supplements. The toxicity of different forms and compounds of selenium is also summarized in this review.

Compost application in integrated and organic fruit cultivation
135-139Views:118Nowadays the success vegetable and fruit production are unimaginable without regular nutrient management. One of the ways to supply the required nutrients in an environmentally friendly way is the application of composts, which is less widespread so far. Compost doses were applied in biological and integrated apple orchards in cooperation with the Institute of Horticultural Science in the years 2010 and 2011. Different changes were resulted by the compost treatments in the examined parameters in case of both apple varieties (Golden Delicious and Pinova). There is no clear effect of compost on the changes of ash-, total acids, Vitamin C and the sugar content until now, because the improvement of the nutritional indicators takes more time. However significant differences were observed after one year between the apple varieties. Higher ash-, total acids and sugar content were measured in case of the apple variety Pinova, while the measurements showed higher Vitamin C content in case of the variety Golden Delicious.

Effect of divided nitrogen and sulfur fertilization on the quality of winter wheat
27-31Views:172The ecological characteristics and agro-ecological conditions in Hungary provide opportunities for quality wheat production. For the successful wheat production besides the favorable conditions; the proper use of expertise and appropriate cultivation techniques are not negligible. Successful cultivation affected by many factors. To some extent we can affect, influence and convert the abiotic factors.
Today, a particularly topical issue is the question of nutrition and that the species’ genetic code can be validated using the appropriate quantity and quality fertilizer. Beyond determining the fertilizer requirements of the winter wheat it is important to align the nutrient to the plant’s nutrient uptake dynamics and to ensure its shared dispensing. In any case, it is important to note the use of autumnal base-fertilizer as complex fertilizer. Hereafter sharing the fertilizer during the growing season with the recommended adequate nitrogen dose.The first top dressing of winter wheat in early spring (the time of tillering) can be made, the second top dressing at the time of stem elongation, and the third top dressing at the end of the blooming can be justified. Determining the rate of fertilizer application depends on the habitat conditions and the specific nutrient needs of plants. In autumn the 1/3 of the planned amount of basic fertilizer should be dispensed (in case of N). During setting our experiment we used 3 doses (0 kg ha-1 N-1 active ingredient; 90 kg ha-1 N-1 active ingredients and 150 kg ha-1 N-1 active ingredient). Application dates beyond the autumn basic fertilization are the following: in one pass in early spring, divided in early spring and the time of run up, early spring and late flowering. In addition to nitrogen the replacement of sulfur gets a prominent role as a result of decreased atmospheric inputs. The proper sulfur supply mainly affects the quality parameters. It influences positively the wheat flour’s measure of value characteristics (gluten properties, volume of bread, dough rheology.
In terms of nitrogen doses; the larger amounts (150 kg ha-1 N-1 drug), is the proposed distributed application, while in the case of lower nitrogen (90 kg ha-1 N-1 drug) in a single pass in the early spring can achieve better results. After using sulfur the quality values among the nutritional parameters that can be associated with gluten properties took up higher values than the samples not treated with sulfur.

Comparison of macroelement and microelement contents of conventionally and organically grown crops
87-92Views:166Nowedays one of the most important issues to discuss is the healthy nutrition: feeding our bodies with high quality nutrients, which is free of chemical residues. The demand for healthy and nutritious food is increasing worldwide, that results in the growing popularity of consumption of organic food. Several studies dealing with the nutrient content of traditional and organic food have been published lately, since it became clear that eating food contaminated with chemical residues damage to health, food and the environment. Therefore it would be desirable to find out if organic food is really superior to conventional one. In our study we analyzed the dry matter, ash, macroelement and trace element content of organically and conventionally grown crops (carrot root, potato tuber and parsnip). Our results provide further information to consumers about the nutritional value of organic and conventional crops.

Seedling morphology of different wheat genotypes at early stages under hydrocultural conditions
249-254Views:213Consuming “sprouted seeds” is one of the most important factors of a healthy diet. An experiment was conducted in the University of Debrecen, Research Centre of Nyíregyháza (Hungary) in 2014 to analyse some morphological traits of four winter wheat genotypes (Triticum aestivum L.) and one spelt (T. spelta) variety. Our results showed that the spelt wheat variety “Franckenkorn” could maintain higher root length throughout the experimental period. On average, both “Perbetei” and “Franckenkorn” varieties could maintain higher root number compared to the other varieties. The extensive breeding line “1401 HK” had the highest shoot length throughout the whole experiment, being significantly higher than the landrace variety “Perbetei” and both of the varieties “KG Bendegúz” and “KG Kunhalom”. It could be concluded that “KG Bendegúz” cultivar and “Perbetei” landrace seem to be the most suitable for aquaculture techniques. In addition, “1401 HK” breeding line can be the most suitable for the production of juice since the minimal required shoot length (12 cm) was achieved within the shortest period of time after sowing (9 days). This breeding line and “Franckenkorn” can also be suitable for production of “wheatgrass”, because it is consumed without roots. Further research is needed to evaluate nutritional values of these genotypes.

Consumption tendencies of foods of animal origin in Hungary
7-17Views:129One of the most important indices of the population's food consumption are the quantities of the consumed foods expressed in a natural measure. In the course of my examination from the 1980 years I examined how our dietary habits changed. I was able to demonstrate it by the time series examination well, in which years and in a what kind of measure these consumer changes occurred. The trend analysis was in it onto my help, that let me be allowed to depict his beat as the changes of the food consumption visual.
In his totality the Hungarian population nutritional and from his consumer customs we may relate that the present nourishment increases it unambiguous the diet pendant the risk of illnesses, furthers their development, aggravates their effect, and contributes to the population's adverse health conditions powerful.
It was over in some years, in a decade on a unfortunate manner, we lost the natural instinct of the selection of the food in a considerable part. Our diet fundamental the narrower and the customs of wider environment, his rules, the social values, beliefs define it. Because of this to feed it is necessary to study it.
The changed and the health-conscious nourishment would be important for him herding back into a upturned dietary habit correct bed with a wide circle recognizing him with the population, his role could be big for the healthy, or functional foods. The nourishment gives his pleasure likewise while we take over healthy foods.
The recognition of the changes of the demand and accompanying him with attention could be the domestic food producers' fundamental interests. The consumer types and the market segments should be mapped, that they suitable marketing a strategy can be aimed at it, and into the direction of the healthy nutrition to push away, and would be need onto an efficient informative campaign, onto an advertisement message formulated well, onto the making aware of this, that let the advertisement supply an educational function in one. -
Leaf reflectance characteristics and yield of spring oat varieties as influenced by varietal divergences and nutritional supply
29-34Views:99Inadequacy of nutrients in the soil and sufficient inaccessibility to nutrients is caused by factors that affect production and productivity of spring oat varieties. Exogenous application of nutrient and real time nutrient assessment can therefore reverse these associated negative consequences. A field experiment was conducted to evaluate the response of spring oat varieties to sulphur and silicon based fertilisation. Eight spring oat varieties, four level of nutrient application was arranged in a split-plot design with three replications. The obtained results showed that foliar application of sulphur improves the grain yield of most nutrients responsive varieties by about 34.7%. However, application of silicon had shown a diminishing return association to grain yield of variety GK Kormorán, GK Pillangó, Lota, Panni. LAI, thousands grain weight, SPAD, NDVI was significantly (p < 0.05) influenced by genetic difference of the tested varieties, developmental plasticity, and nutrient application. Significantly higher grain yield was obtained from the variety Mv Pehely than the other tested varieties. Therefore, it could be inferred that a combined use of nutrient responsive spring oat varieties and sulphur containing fertilisers could be important agronomic practice to improve grain yield and to develop climate resilient oat varieties.

Bacteria in the milk of sheep with or without mastitis- mini Review
47-52Views:338From a nutritional point of view, sheep milk is more valuable than cow and goat milk and the interest for sheep milk is increasing in many countries. However, sheep milk is easily contaminated during milking, handling, and transport and it is an ideal medium for bacterial propagation. Consequently, sheep milk spoils quite quickly. The proper, clean handling of milk is not only of sanitarian interest, but it also serves the farmers’ interests, because contaminated milk may not be distributed, and is unsuitable for producing good quality products. Following this technological trend, this review addresses the bacterial composition of sheep milk with and without mastitis. Even though sheep milk contains a lot of bacteria, this review article highlighted total plate count, Enterobacteriaceae, coliform, Staphylococcus aureus, Escherichia coli, Listeria monocytogenes, Campylobacter, Salmonella spp. and Streptococcus spp. Mastitis in sheep is a vital cause of mortality, reduction in milk production and early culling. The reported risk factors for mastitis in sheep were age, a case of mastitis, breed, husbandry systems, and location. The main priority should be implementation of programs to minimize human pathogenic bacteria and mastitis in raw ewe milk.

Folic acid content of beetroot leaf and root by different growing stages and genotypes
115-119Views:243An increasing interest has been observed of beetroot leaf as a salad component due to recent studies focusing on their nutritional value. The randomized field experiment was carried out on lowland chernozem soil with 6 varieties, 3 replications and 2 sowing dates. Sampling was performed on 23 of August 2018 at the stage of 30 and 50 days of vegetation, where leaf (30 and 50 days) and root (50 days) were collected. Total dry matter, folic acid and nitrate content were evaluated.
The results of this investigation show that higher total dry matter content was measured in the root (8.47–10.30%) compared to the leaf in both developmental stages (6.47–9.20%). Nevertheless, higher folic acid content was found in the young leaves of 30 and 50 days of development (58.77–113.86 µg 100g-1). Among the examined varieties, Bonel has presented great amount of folic acid not only in the leaves (99.35–113.61 µg 100g-1), but also in the root (89.99 µg 100g-1). Finally, lower nitrate content was found in Libero (316.16 mg kg-1) at 30 days and in Akela (340.41 mg kg-1) at 50 days of development. Thereby, fresh consumption of beetroot leaves are highly recommended.
