Realisation of customer focus from quality and forage safety aspects in the Hungarian mixed feed production
35-38Views:222Customer focus is one of the main principles of Total Quality Management, and it is inevitable for long term, mutually successful vendorcustomer partnerships. The strictly controlled quality management systems of animal feed industry ensure that product quality meets the expectations of all parties involved and, indirectly the reliability of human food raw materials. Meanwhile, the participants of agricultural production are variably quality conscious, so feed manufacturers support their supply chain and also their customers with professional background and they play a key role in safe food chains from farm to fork.

Digital signature adaptation to e-commerce
153-159Views:208Expansions of the use of the Internet applications are increasing continuously. The distances have disappeared and decreased the necessary trade time. The bases of the businesses are the confidence and the other parties identification. The new communication channel demands new identify methods. The digital sign is a standard and easy to use possibility to identify one another and their documents, e-mails etc. In my paper I show the
availability of e-commerce services which can be used to identify by digital sign in Hungary. -
Technological and Economic Analysis on the Hungarian Rice Sector
226-233Views:244Hungary lies on the northern edge of rice production area. According to this, the climatic conditions area not perfect for this species. The production area of rice involves typically the poorer quality soils, however these meet the requirements of rice. In Hungary exclusively domestic types are grown which have high yield and good quality and these are usually wore successful than foreign types. On the other hand, these Hungarian types should be improved considering safety in production. Nowadays, rice is grown in large scale companies with 300-1400 hectares, where production technology already exists, machinery is suitable, however the latter one a little bit old.
The average yields of the analysed companies were 3-4 t/ha in the past few years, which were a little bit above the national averages. The operating cost per hectare is almost 200 thousand HUF, from which the main part is the cost of machinery (35%) and the material cost (34%). The main part of the latter one is the irrigation costs (30%). The average cost, calculated from the total production cost, is 80 thousand HUF/t. Considering the above-mentioned costs and the price of rice (75 thousand HUF/t) it can be stated that the profitability of the rice sector is not the best, the cost rated profitability is -6.6%. According to the results of this analysis possibilities for the increase in profitability and improvement are increased subsidies and market price, as well as genetic improvement. -
The effect of breed and stage of lactation on the microbiological status of raw milk
37-45Views:772The microbiological quality of the milk is important not only for food safety, but it can also influence the quality of dairy products. The microbiological status of raw cow milk can be influenced by many factors. Our aim was to determine whether there was a difference between the microbiological quality of milk of two different cow breeds (Holstein Friesian and Jersey) kept and milked in the same conditions, and how the microbiological quality of the raw cow milk changed during lactation (beginning, mid, and end). Samples were taken and analysed in July, August and September in 2018 from two dairy farms in Hajdú-Bihar county. During the conducted studies, the total plate count (TPC), the coliform count, the Staphylococcus aureus count and the coagulase-negative Staphylococcus (CNS) count of raw milk samples were determined.
There was no significant difference (P>0.05) between the milk of the Holstein Friesian and Jersey breeds in the case of TPC. However, the mean coliform count of milk samples taken from Holstein Friesian cows was significantly lower (P<0.05) than the mean coliform count of milk samples taken from Jersey cows. S. aureus was detected in one of the twelve milk samples taken from Holstein Friesian cows, and in two of the eleven milk samples taken from Jersey cows. CNS was found in larger amount in milk samples taken from Holstein Friesian cows, and the difference was significant (P<0.05). Both TPC and CNS count were significantly higher (P<0.05) in individual milk samples taken at the end stage of lactation, than in samples taken in the earlier stages of lactation from Farm “A”. However, in the case of Farm “B”, there was no significant difference (P>0.05) in colony counts at different stages of lactation. S. aureus was only present in milk samples that collected from cows, which were at the beginning and middle stages of lactation. Testimg the hemolysin production ability of S. aureus strains isolated from the raw milk samples, only weak hemolysis was observed on blood agar. In case of antibiotic resistance testing, it was found that all strains were susceptible to cefoxitin, chloramphenicol, clindamycin, erythromycin, gentamicin, penicillin G, tetracycline and trimethoprim/sulphamethoxazole.
Based on the results of our studies, staphylococci were detected in a higher amount in the milk of Holstein Friesian cows, and coliform bacteria were detected in a higher number in the milk of Jersey cows. Summing up the results of the milk samples taken from the different stages of lactation in one of the farms, it can be concluded that higher TPC and CNS count could be detected at the end stage of lactation than in the samples taken from the earlier stages of lactation. The fact that at the end of lactation the microorganisms could be detected in a higher colony count may be related to the fact that teats could be damaged during lactation by the milking machine, which increased the chance of imvading the microorganisms into the udder.

Investigations of Thrips tabaci and Aeolothrips intermedius population dynamics in tobacco plantations
121-127Views:354Studies were conducted between 2015 and 2017 with yellow sticky traps in seven tobacco plantations. The purpose was to determine when and in what numbers onion thrips individuals can settle into tobacco plantations. The primary objective of the study was to determine the proper timing of chemical treatments, furthermore, the determination of crucial factors that can influence the population dynamics of Thrips tabaci.

Novel Applications of Microwave Techniques in the Food and Environmental Industries
29-34Views:242During the microwave processing, despite the conventional heating, the material heats consistently inside. This property of microwave is utilized by drying and dehydration processes. The thermal sensitivity of raw materials of food industry requires development of gentle, fast and controllable technologies, which is realizable by means of combination of conventional and microwave techniques. The other important application area of the microwave technique is food industrial practice is enhancing the microbial safety of products, mainly by pasteurization processes. In recent time the strict environmental regulation necessitate developing more effective treatment of wastes, waste waters and sewage sludge. Because a part of these techniques are heat and power demanded, the microwave technique may be an alternative process in execution of sludge conditioning, drying or gasification and pyrolysis.

Application of the decision tree, as the weak point of the HACCP system development
63-70Views:233In this article we have compared the „decision tree” method –suitable for the CCP determination during the HACCP systemintroduction – with the objective measurement method. We have found out, that the CCP-s from the two method differ from each other. So, the empirical „decision tree” method is suitable for determination of CCP-s only limited, while the measurementbased method determines the CCP-s objectively. Only the right
CCP-determination can guarantee safe food. -
Agri-Environmental Issues in the National Sustainable Development Strategy of the Member States of the Enlarged EU
346-353Views:211In preparation for the World Summit on Sustainable Development (Johannesburg), almost all EU member-states and some accession countries presented their national strategies for sustainable development (NSSD) during the summer of 2002. Along with other countries, Hungary is only now setting up this important document. Everywhere during the last decade, as in the EU countries, the intention was to involve the environmental problems into other political questions (agricultural, energy and transport policy, etc.). Today the strategy-builders have given up the sectoral view because of difficulties and setbacks, and use a view aiming the problem.
Agri-environmental issues appear as the elements of sustainability in the national strategies. For example, in accordance with the danger of global warming, the emission of green-house gasses of agriculture; in line with eco-efficiency, the production of renewable raw materials and energy sources originating from agriculture, and, in relation to changing lifestyle, food-safety and the future of biological agriculture will be disputed. With this study, I investigate the main characteristics of sustainable development strategies at both the EU level and at the level of the different member states from an agri-environmental point of view.
