Precision fermentation uses microbes to produce specific ingredients that influence the functionality and taste of foods. The ingredients created through this type of fermentation, which include proteins, vitamins, enzymes, fats and natural pigments, can be used to enhance plant-based goods and lab-grown meat to make foods that more closely resemble traditional animal products.

“One thing that we know about alternative protein products is that it’s really important that we try to reach taste and price parity with conventional animal products,” said Shayna Fertig, a senior adviser at the Good Food Institute.
