Abstract:

The accelerated technology to prepare rye-wheat bread at mini-enterprises and restaurants was proposed. The technology involves the use of acidulants. The multicomponent acidulants “Optimum 1” and “Optimum 2” were developed to intensify the technology of rye-wheat bread. The composition of the acidulants includes the enzyme preparations (EP) Glusim 10000 Mono (glucose oxidase, which contributes to the improvement of structural and mechanical properties of dough, Pentopan 500 BG (a mixture of pentosanase and hemicellulase), which promotes the modification of non-starch polysaccharides and provides elastic crumb in the products. Citric acid and dry whey (DW) were added to the acidulants in order to ensure proper acidity of dough and intensify the process of its fermentation, while rye fermented malt (RFM) was added to improve organoleptic parameters. Guar gum was added in order to increase the water-absorbing capacity of dough and to preserve freshness of products during storage. Optimal dosage of MCA “Optimum 1” and “Optimum 2” in the formulation of rye-wheat bread is 2 % by weight of flour.Technological aspects of the use of acidulants were considered. The processes were considered related to staling, loss of organoleptic and physical-chemical indicators of bread quality during storage. The positive influence of acidulants on the parameters of crustiness and swelling of bread crumb due to the accelerated technology of its preparation was proved. It was established that the use of acidulants helps to slow down the process of rye-wheat bread staling. The positive effect of acidulants on the taste and flavor of finished products was obtained. The obtained results prove the expediency of using the developed multicomponent acidulants “Optimum 1” and “Optimum 2” in the technology of rye-wheat bread employing its accelerated preparation. The use of the developed acidulants helps to reduce the technological process of baking rye-wheat bread by 2.5‒3 times and ensures preservation of freshness, taste and flavor of the finished products Author Biographies Tatyana Sylchuk, National University of Food Technologies Volodymyrska str., 68, Kyiv, Ukraine, 01601 PhD, Associate Professor Department of hotel-restaurant business
