Foodwastes can be utilized to produce ethanol, a promising alternative energy source for the limited crude oil. There are mainly two processes involved in the conversion: hydrolysis of polysaccharides in the foodwastes to produce reducing sugars, and fermentation of the sugars to ethanol. The cost of ethanol production from foodwastes is relatively high based on current technologies, and the main challenges are the low yield and high cost of hydrolysis process. Considerable research efforts have been made to improve the hydrolysis of foodwastes. Pretreatment of foodwastes to remove starch and polysaccharides can significantly enhance the hydrolysis of sugars. Foodwastes were hydrolyzed using various concentration of glucoamylase,
carbohydrases and both mixing enzymes in order to obtain high glucose yield for ethanol fermentation; mixing enzymes revealed higher performance(2.53 g-glucose/g-dry foodwastes) than each glucoamylase (2.32) and carbohydrases (2.01). As a result, our results suggest that foodwastes can be a high potential substrate for ethanol production.
