Abstrakt: | The results showed that from the five amino acids investigated, only L-cysteine hydrochloride monohydrate hydrate is a reductant while the others are stronger or weaker oxidants. L-tryptophan was found to be the most suitable oxidising agent, followed by inactivated dry yeast and L-threonine. However, in order to eliminate fast softening of the dough with L-threonine, shorter processing time, i.e. reduced mixing and fermentation time, should "be used. L-tyrosine can be used as an oxidising additive as well, but its instability in dough prevents serious practical application. Oxidants are able to strengthen the gluten network and thus increase the elasticity of dough, as a result of which bakery products have an increased volume and better porosity. | ||||||||||
