STRUCTURE AND FUNCTIONAL PROPERTIES OF WHEAT BREAD AND PASTA PRODUCED THROUGH SUPPLEMENTATION OF RS2 AND RS3 TO WHEAT FLOUR FROM TRADITIONALPOLISH AND RUSSIAN CULTIVARS

摘要

Bread and pasta produced from a mixture of common wheat flour and commercial preparations of RS2 and RS3 were investigated. Irrespective of RS types, their addition to flour leads to changes in structure, gel strength, hardness and gumminess of breadcrumb. At the same time, an addition of RS does not exert any influence on the elasticity nor cohesiveness. Some features in relaxation behavior of bread samples produced with an addition of RS2 are discussed. In contrast to RS3, the application of RS2 during pasta processing leads to some increase in productivity of pasta extruder, shortening of cooking time, but does not exert any influence on the loss of dry substance during cooking as compared with the control. White bread and pasta containing 7-10% RS are of good organoleptic properties. Extension of storage time of pasta is accompanied by an increase in RS content, which can be reflected in the physiological effect of the dishes based on this type of pasta.
