Even minor variations in the metabolic profile of
Saccharomyces cerevisiae affect the texture of dough and bread. Based on the assumption of a disintegrative interaction between CO
2 and glutathione (GSH), material properties of biologically and chemically aerated starch-protein-matrices were evaluated. It was shown, that GSH-amounts diffusing from yeast into the liquid dough phase increase the gas retention capacity. Carbon dioxide provoked a mechanic and GSH a chemical disintegration. In the dough stadium, the latter had a positive effect on the extensibility, while it influenced the thermically induced solidification of the cellular structure in a negative way. Thus, the obtained results confirm the initial hypothesis.
