What it is

Active kefir cultures are a symbiotic mixture of bacteria and yeasts, often referred to as a 'kefir grain.' These microorganisms are used to ferment milk, producing a tangy, effervescent beverage similar to yogurt.

Why it's used

Kefir cultures are primarily used to ferment dairy products, imparting a distinct flavor and texture. They are often added to yogurt, ice cream, and other frozen desserts to provide a probiotic benefit and a characteristic tangy taste.

Health notes

Active kefir cultures are generally recognized as safe (GRAS) by the FDA for use in food. They are a source of probiotics, which are live microorganisms that may offer health benefits when consumed in adequate amounts, such as supporting gut health. Regulatory bodies like EFSA have reviewed probiotics, but specific health claims are often subject to ongoing research and regulatory approval.

Allergen info

Kefir cultures themselves are not a major allergen. However, they are typically used to ferment milk, which is a major allergen. Check product labels for specific allergen information.
