What You Need to Know
Proteolytic enzymes from Aspergillus oryzae hydrolyze soy proteins into peptides and glutamic acid, while lactic acid bacteria lower pH to inhibit spoilage. Yeast such as Saccharomyces cerevisiae ferments sugars into ethanol, and spontaneous fish fermentation generates amino acids and peptides under high salt conditions.
