The universal concern on energy and environmental preservation
has generated increasing research focus on biomass energy
worldwide. Finding proper raw materials for biomass energy production
is important. Food waste is a type of biomass waste with
high organic quantity and moisture content; it is easily perishable
and harmful to the environment if not treated properly [1]. High
carbon source and abundance of nutrients make food waste an
ideal raw material for value-added products, such as methane, lactic
acid (LA) fermentation and hydrogen production [2–4]. Ethanol
production from food waste can reduce pollution and serve as a
resource alternative [5,6]. Fuel ethanol is an important biomass
energy because it is simple and has the ability to be mixed with
gasoline. Ethanol production usually undergoes cooking process,
