Soy sauce relies on fungal koji and brine fermentation

Aspergillus oryzae mold breaks down bean proteins into savoury glutamates

Traditional soy sauce production begins by inoculating boiled soybeans and roasted wheat with Aspergillus oryzae mold to form koji. The koji is mixed with salt brine to create a mash called moromi, which ferments for months. Fungal enzymes break down starches into sugars and proteins into amino acids, creating rich savoury flavours.
