Nonfat Milk Cultures

Nonfat milk cultures are live microorganisms, typically bacteria, that are grown in skim milk. These cultures are essential for the fermentation process in dairy products, transforming milk into products like yogurt and cheese, and also contribute to the flavor and texture of various foods.

Manufacturers use nonfat milk cultures to develop characteristic tangy flavors and creamy textures in foods like sour cream, cheese, and cultured buttermilk. They are also added to snacks such as potato chips and salad kits to provide a savory, cheesy, or sour cream-like taste profile.

Nonfat milk cultures are generally recognized as safe (GRAS) by the FDA for use in food. The live microorganisms in these cultures are often referred to as probiotics, which are beneficial bacteria that may support gut health. Regulatory bodies like the WHO/FAO's JECFA have evaluated similar cultures, and EFSA has assessed the safety of specific probiotic strains. Evidence regarding the health benefits of specific strains continues to be researched.
