Abstract
The article is concerned with the study of impact that individual raw components have on bread quality. The object of research is bread made of straight white wheat flour: fat-free bread with the use of faucet or activated dough water (treated in an acoustic source of elastic vibrations, ultrasonic technological device “Volna” of UZTA-0,4/22-OM model, operating on a frequency of (22 ± 1,65) kHz and an output power of 400 watt, at exposure time of 5 mins; enriched foodstuff with combined herbal supplement on the basis of stevioside and fucoidan (with complete substitution of sugar)). The influence of activated water and combined herbal supplement on organoleptic (visual form, the color of crust, crumb condition, taste, clumping while chewing, friability) and physical and chemical (moisture, porosity, acidity) indicators of quality is estimated. Yeast activity of the dough obtained with the use of activated water and combined herbal supplement is studied. The obtained results prove the possibility for using activated water and combined herbal supplement in order to enhance quality of freshly baked bread. The use of activated water stimulates accumulation of yeast cells, intensification of the dough-making process, and more intense development of the dough’s proteinaceous matrix. As a result, the produced bread is in high demand; it has good visual form, gained volume, even structure. At that, “friability” index is significantly decreased, which is good for the organoleptical characteristics of the bread. The use of different recipe components while producing bread (fucoidan, stevioside and fucoidan, stevia syrup and fucoidan) results in intensification of the dough-making process, which in turn positively influences finished products’ quality. All tested samples with the supplement possess increased porosity of the crumb. Decrease of “friability” index and increase of “swelling” index are observed.
