What it is

Active cultures are live microorganisms, typically bacteria or yeasts, that are added to foods. They are often naturally present in fermented foods or can be added during processing. These cultures are responsible for the characteristic changes in flavor, texture, and aroma of fermented products.

Why it's used

Active cultures are primarily used to produce fermented foods like yogurt, kefir, sauerkraut, and kimchi. They contribute to the tangy flavor and unique textures of these foods. In some products, they are added to support gut health.

Health notes

Active cultures are generally recognized as safe (GRAS) by the FDA for use in food. While specific strains are being researched for potential health benefits, such as improved digestion, scientific consensus on these effects is still developing. International bodies like JECFA have evaluated some specific probiotic strains, but their general use in food is not typically associated with adverse effects at normal consumption levels.

Allergen info

Active cultures themselves are not a major allergen. However, they may be found in foods that contain major allergens, such as dairy in yogurt.
