A study published in the Journal of Food and Bioproducts Processing found that through solid state fermentation, it is possible to develop a multi-enzyme solution rich in glucoamylase and protease from waste bread.
“Glucoamylases and proteases are the most widely used industrial enzymes with applications in various industries,” the researchers wrote.
These enzymes could also be used to produce nutrient rich hydrolysates which can be fermented to produce value-added chemical products like ethanol and lactic acid, they added.
