I performed an experiment in which I tested fermentation rate using a gaspressuresensor over a period of 15 minutes with fructose, glucose and sucrose and baker's yeast. The result was that fructose produced most sugar and fastest, then glucose at a slower rate, then sucrose, for which virtually no CO2 was produced. I have no idea why this happened, and why fructose reacted faster than glucose? Does it have to do with the yeast taking a very very long time to break sucrose's glycosidic linkage? (ps. the ph was maintained at 7 throughout the experiment, and temperature at 37C. Thanks so much!!
Re: What order are fructose, glucose and sucrose fermented in terms of speed?
