    Introduction: Based on preliminary research, the hypothesis of the present study was that at temperatures higher or lower than 40 degrees Celsius fermentation is inhibited. Alcoholic fermentation is used in food production such as brewing, winemaking, and baking (Campbell). Thus optimizing fermentation and understanding the effect of various environmental factors can have important economic and social benefits. The production of CO2 is being assessed to show the rate of fermentation at certain time intervals. This data could be used to optimize fermentation of yeast by finding the optimum temperature. Based on the research done by Yan Lin et al there were evidence to suggest that “20 -35 degrees is the ideal range for fermentation and at higher…

During fermentation, some strains of yeast decompose sugars to derive energy, and in the process they produce ethanol as a waste product. When bread dough is being made, yeast is added to make dough rise. This occurs because the yeast ferments sugar releasing carbon dioxide which causes the dough to rise and creates holes in the bread. This carbon dioxide released…
