Thermo-mechanic and sensory properties of wheat and rye breads produced with varying concentration of the additive

Abstract

The effects of different concentrations of complex additive containing emulsifiers, oxidoreductive substances and enzymes, on the rheological conditions of dough and sensory properties of three groups of bread were investigated. The dough obtained from mixed wheat and rye flours had the best initial quality and the lowest degree of protein network weakening. The best expected baking properties were shown by the white wheat flour due to the least damage of its starch. The use of the additive had an effect on the absorption of water and on the majority of C-values of all sorts of flour. The amount of additive had a significant effect on the sensory properties of wheat bread crumb texture. Also, storage duration significantly affected (p < 0.01) the sensory properties of integral wheat bread aroma-taste and the weighted mean score. The interaction of these two factors had no significant effect on any of sensory properties of the investigated groups of bread.
