Comparison of chemical parameters of enzyme active and inactive malt types
161-166Views:246Nowadays 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).

Búzalisztek minőségének becslése tészta nyújtás-szakítás alapján állományvizsgáló műszerrel
38-44Views:92Literature experience was utilised to develop a method for the extensograph analog testing of paste with a QTS25 Texture Analyser. 54 wheat flour samples from the same variety from variety-preservation experiments at the Szeged were tested with this method. A study was made to establish whether the method is suitable for the estimation of results derived by traditional classification (trial baking, farinograph and gluten tests).
A close and significant correlation was found between the hardness and area data measured with a QTS25 micro-extensograph, the farinograph values and the gluten spreading data, and also between the stretching index (BC/AC) and the water uptake capacity. These correlations correspond well with the findings from a previous experimental series on industrial flour samples. A close and significant correlation was likewise observed between the grain hardness established by the MININFRA method and all the QTS25 micro-extensograph data. In contrast with earlier QTS25 data, however a close correlation was not found between the QTS25 data and the loaf characteristics.
With the use of micro-extensograph data, the estimation of the baking industry value has been improved through stepwise variable selection, with the inclusion of several variables. The estimation of loaf volume could also be solved by means of stepwise variable selection with the inclusion of QTS25 and MININFRA data. -
Opportunities for improving the nutritional value of cereal-based products
275-278Views:278We 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 .
