Abstract：This research was done to make use of the waste food as main raw material to produce ethanol. The waste food were mixed and agitated with some accessories, and then fermentated with Saccharomyces cerevisiae. The research was conducted to study the adding level of corn powder, the enzyme acting time, fermentation time, fermentation temperature and inoculating level, pH on the production of ethanol from the waste food. Results showed that the optimal conditions were: corn powder 22%, the enzyme acting for 35 mins, fermention hydrolysing as 72 h, fermention temperature as 32℃, inoculating level 10%, the starting pH 4.0.
