It is also used in the baking process as a leavening agent; yeast releasing gas into their environment results in the spongy-like texture of breads and cakes. Because of its role in fermentation, humans have known about and used Saccharomyces cerevisiae for a long time.
Once the dough or ferment temperature exceeds about 105 F (41 C), the fermentation rate declines. Yeast enzymes are generally inhibited at this temperature. Table 5 below (derived from Pyler) correlates the effects gas production and temperature in liquid ferments.As can be seen, gas production increases as the temperature rises to 100 F (38 C). It then declines at higher temperatures.east enzymes are generally inhibited at this temperature. Table 5 below (derived from Pyler) correlates the effects gas production and temperature in liquid ferments. As can be seen, gas production increases as the temperature rises to 100 F (38 C).
