Lactic Acid Starter Culture

Lactic acid starter cultures are beneficial microorganisms, primarily bacteria, that are used to ferment foods. These cultures produce lactic acid, which contributes to the preservation, flavor, and texture of various food products. They are typically grown in controlled environments for commercial use.

Manufacturers add lactic acid starter cultures to foods to initiate fermentation, which helps to preserve the product and develop characteristic flavors and textures. They are commonly found in fermented meats like pepperoni and salami, as well as in dairy products such as yogurt and cheese, and in sourdough bread.

Lactic acid starter cultures are generally recognized as safe for their intended use in food production. These beneficial microorganisms are widely consumed in fermented foods and are not typically associated with adverse health effects. JECFA has evaluated lactic acid itself and established an acceptable daily intake; for the starter cultures (microorganisms), they are considered safe for their traditional use in food fermentation. There are no major controversies regarding the safety of common lactic acid starter cultures when used as intended.
