How to Fermentation with Microorganisms

What You Need to Know

Microorganisms like koji or kefir produce compounds with unique flavors and aromas through the breakdown of complex molecules. This process involves the action of enzymes like amylase, which breaks down starches into sugars, and probiotic bacteria and yeast, which break down lactose and casein. The resulting compounds can have antimicrobial properties, making fermentation a useful method for preservation.
