What it is

Lactobacillus delbrueckii is a type of bacteria naturally found in the human gut and in fermented foods. It is a lactic acid bacterium that ferments sugars into lactic acid. It is often grown in controlled conditions for use as a starter culture in food production.

Why it's used

This bacterium is primarily used as a probiotic, meaning it is added to foods to provide potential health benefits. It is commonly found in dairy products like yogurt and kefir, and sometimes in other fermented foods. It helps break down lactose and can contribute to the texture and flavor of fermented products.

Health notes

Lactobacillus delbrueckii is generally recognized as safe (GRAS) by the FDA for use in food. It is considered a beneficial microorganism when consumed as part of a healthy diet. International bodies like the European Food Safety Authority (EFSA) have evaluated probiotics, and JECFA has also evaluated some strains. Research is ongoing into the specific health effects of different strains of Lactobacillus, with some studies suggesting benefits for gut health and digestion.

Allergen info

Lactobacillus delbrueckii is not derived from any of the nine FDA major allergens. It is a bacterium, not a protein from a major allergen source. Gluten is not applicable.
