VI. Data Analysis & Discussions

DISCUSSION:

For the hypothesis, yeast was not used in the experiment that we researched on online, so its probably why there were less alcohol compared to our experiment with yeast. As yeast uses the glucose and sugar in the rice, more alcohol would be made. Without yeast, the starch can only be fermented by a certain amount, with the yeast however, the starch would be converted into alcohol.

Details: We figured out that also when we researched for our hypothesis, the percentage of alcohol after fermentation was without yeast. However, our results had fermented with yeast and that explains the reason for the big difference between our hypothesis and actual results.
