The dissertation is devoted to scientific substantiation and development of accelerated technologies of bread bakery products with mixture of rye and wheat flour for the restaurant business establishments and mini-enterprises.
There was offered new technological solutions for the accelerated production of rye-wheat bread bakery products due to the introduction of spontaneous sour dough (SSD), the development of polycomponent acidulents (PA) and using of new types of raw materials with a high content of food fibers. There was offered new model for the culturing of SSD, which are based on the accumulation of organic acids that is easily dissociating on ions, that is insure high quality semifinished and finished bread bakery products.
There was shown that the composition of microorganisms formed during spontaneous fermentation of sour dough is stabilized by systematic renewal of sour dough. There were investigated biotechnological properties of SSD, parameters of technological process and figures of bread quality with its use. There was shown that in contrast to sour dough of pure cultures of microorganisms, in SSD, predominant accumulation of heterofermentative lactic acid bacteria, which results in the accumulation of organic acids in this sour dough, is higher than in lactic acid, the dissociation constant. For the same titrated acidity, SSD has lower pH value; this is result of suppressed development of undesirable microflora in sour dough.
Theoretically and experimentally there was proved technology of rye-wheat bread bakery products with using SSD.
There was shown that the most popular way of intensifying technological process of making rye-wheat bread bakery products is the use of acidulents and conditioners with various spectrum of action.
On the ground of analysis of their influence on technological process and quality of finished products, there was developed composition of the compositions of the new multicomponent acidulents (MCA) “Optimal 1” and “Optimal 2”, which considered effect of acidulents’ components on main dough biopolymers (proteins, starch, pentosani) and quality indicators of bread.
There was developed composition of multicomponent acidulant "Optimal 1", which is consisted of enzyme preparations of glucooxidase, pentosanase and hemicelulase, citric acid, rye fermented malt, dry lactoserum and guar gum, and also composition of multicomponent acidulant "Optimal 2", which composition consist of enzyme preparations of fungal α -amylases and pentosanase, ascorbic acid and citric acid, rye fermented malt, dry lactoserum and guar gum. Using of developed multicomponent acidulents in production of rye-wheat bread bakery products can reduce t continuance of technological process by 2,5-3 times.
There was shown that use of MCA "Optimal 1" and the "Optimal 2" control panel in the production of rye-wheat bread bakery products contributes to intensification of microbiological and biochemical transformations in the dough.
There was obtained new scientific data about formation of wheat flour proteins complexes and pentosan of rye flour, which explains the peculiarities of formation of gluten carcass in rye-wheat dough and is confirmed by increase in its viscous-plastic properties.
There was given scientific of using of concentrates of peanut food fibers (PeFF) and potato dietary fiber (PoFF) in order to create functional bakery products.
There was established qualitative composition of polysaccharide complex of PeFF and PoFF concentrates. It was established that the total content of food fibers in peanut food fibers is 61,6%, in potato food fiber – 77,1%.
There was developed technological instructions and composition of rye-wheat bakery products with concentrates of PeFF and PoFF, which allowed expanding the range of bread bakery products, with contents of ingredients of health-improving action.
There was proved that addition of PeFF and PoFF to dough provide increase in content of food fibers.
