Yeast And Bacteria Cultures

Yeast and bacteria cultures are live microorganisms, often referred to as probiotics. They are typically grown in a liquid medium, such as sweetened tea or juice, under controlled conditions to ensure the desired strains thrive.

These cultures are added to foods and beverages to introduce beneficial live microorganisms, often for their potential probiotic benefits. They are commonly found in fermented products like kombucha, kefir, and some yogurts, where they contribute to flavor and texture as well as health-promoting properties.

Yeast and bacteria cultures used in foods are generally recognized as safe (GRAS) by the FDA for their intended use. While specific strains are researched for their effects on gut health, the FDA does not pre-approve dietary supplements or probiotics. International bodies like JECFA have evaluated some related microorganisms, but specific evaluations for all food-grade cultures may vary. Research into the health benefits of probiotics is ongoing, with some studies suggesting positive effects on digestive health, while others show mixed results.
