Yeast Vinegar

Yeast vinegar is a type of vinegar made from the fermentation of yeast. Yeast, a type of fungus, consumes sugars and produces alcohol and carbon dioxide. This alcohol is then further fermented into acetic acid, the main component of vinegar.

Yeast vinegar is used as a food ingredient primarily for its acidic flavor. It adds a tangy taste to foods and can also act as a preservative. It is commonly found in salad dressings, sauces, and marinades.

Yeast vinegar is generally recognized as safe (GRAS) by the FDA for use in food. Acetic acid, the main component of vinegar, has been studied for potential health effects, but results are mixed and not conclusive. Regulatory bodies like EFSA have evaluated acetic acid, but no specific health claims are associated with typical dietary intake of yeast vinegar. It is not known to be harmful when consumed in amounts typically found in food.
