Comparison of chemical parameters of enzyme active and inactive malt types
161-166Views:199Nowadays there is an increasing emphasis on the use of raw materials. Typically, raw materials – in this study malt – are used in animal feeds and used in the brewing industry. However, in terms of quality (eg. high fibre content), these can be included in human nutrition, we have limited information on this possibility. The aim of our work was to compare different malt flours and examine the possibility of using malt in the baking industry. We were to investigate some of the most relevant parameters, such as dietary fibre content, crude protein content, fat content, carbohydrate content, dry matter content, moisture content, salt and energy content. In the future, we aim to conduct a research on some of these parameters with different malt types as the brewing industry uses novel ingredients different cereals, pseudocereals such as amaranth (Amaranthus spp.), oat (Avena sativa L.), quinoa (Chenopodium quinoa Willd.) in addition to the spring barley (Hordeum vulgare L.) or wheat (Triticum aestivum L.). Based on brewing studies, malt has a high fibre and protein content. Having these advantageous qualities, malt should be part of humans’ healthy diet. Using malt flour in the baking industry can be a new direction which can lead to creating a healthier lifestyle and healthier eating habits than suggested by the WHO (World Health Organization).

The effect of climatic change on the rheological properties of winter wheat doughs
96-100Views:77In present paper we have examined the effect of climatic change on the extensigraph characteristics of wheat-flours. The baking quality
of winter wheat is largely determined by cultivar, but it can be influenced by weather conditions during growing period. Flours were from 5
cultivars grown at one location in three cropping years. We have found that the extensigraph properties of dough are affected by the weather
conditions, nevertheless, different cultivars distinctly react to the increase of temperature and decrease of precipitation. In generally, the
higher average day temperature and lower precipitation level is favourable to produce winter wheat flour with better quality -
Opportunities for improving the nutritional value of cereal-based products
275-278Views:159We 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 .

Examination of different grain hardness varieties of the grinding technology properties of wheat
423-435Views:173In the mill industry, the purpose of the grinding technology is to separate wheat endospermium and shell and to recover grists. The most important and the highest energy requirement operation is shredding. Flour quantity and quality produced from wheat depends on the variety of wheat that will be shredded, the type of grinding equipment and the condition used before the grinding. For this reason, during my experiments, I ground two grain structured varieties of wheat in laboratory conditions using a disk grinder, stone grinder and roll grinder in air-dry and conditioned states. We measured the equipment’s performance and the produced grist’s particle size distribution, followed by the calculation of the energy requirements of the grinders. In the grinding experiments we compared the ash contents of the different particle sized grist’s fractions to map the wheat’s particular properties.

Surface polishing method application to reduce micotoxin content of mill wheat
339-342Views:138The fungi causing the infection and most of the harmful toxins they produce are concentrated in the bran of the grain, thus the intensive surface cleaning, the so-called debranning operation could allow the reduction of contamination in the milling technology. The essence of the PeriTec technology – originally developed by SATAKE, a Japanese company, to clean rice – is that it gradually removes the bran layers of the grain by mechanical means before further processing. We modeled the PeriTec technology with a laboratory size, batch-operating, horizontal debranning machine by SATAKE. The flour, milled grain after grinding 40 sec, the initial toxin content was only a small proportion (~15–20%) measured. The results showed that below the limit of DON toxin contaminated wheat (DON: 1.15 mg kg-1) during the grinding surface of the detached bran toxin contamination shows a very high (6.16 mg kg-1). The 40 seconds debranning before grinding shows lower DON toxin content than without debranning. So it is importance before the grinding. The toxin contamination of the bran fractions is significantly reduced, which is importance to the feeding point. As a result of debranning, the toxin content of the grinding fractions decreased, which justifies that that PeriTec method is suitable for the reduction of toxin contamination.
