Streptococcus Diacetylactis

Streptococcus diacetylactis is a type of lactic acid bacteria. It is commonly found in dairy products and is often used in food production to create specific flavors and textures. It is grown in controlled environments for use as a food ingredient.

This bacterium is primarily used as a starter culture in the production of fermented dairy products like yogurt and cheese. It helps to develop the characteristic tangy flavor and aroma in these foods. It is also used to produce diacetyl, a compound that gives butter its flavor.

Streptococcus diacetylactis is generally recognized as safe (GRAS) by the FDA for its intended use in food. It is a common component of probiotic cultures found in fermented foods, and some research suggests potential benefits for gut health, though more studies are needed. International bodies like JECFA have evaluated similar bacterial cultures, but specific evaluations for S. diacetylactis may vary.
