Grain Vinegar Citric Acid

Grain vinegar is made by fermenting a grain, such as corn or barley, into alcohol and then into acetic acid. Citric acid is a weak organic acid that occurs naturally in citrus fruits like lemons and limes. It is often produced commercially through the fermentation of sugar by specific molds.

Grain vinegar is used to add a sour or tangy flavor to foods like pickles, sauces, and marinades. Citric acid is used as a flavor enhancer to provide tartness, as a preservative to extend shelf life, and as an acidity regulator in beverages, candies, and baked goods.

Both grain vinegar and citric acid are generally recognized as safe (GRAS) by the FDA for use in food. Citric acid is a common component of human metabolism. Regulatory bodies like JECFA and EFSA have evaluated citric acid and found it safe for consumption. No significant health concerns are associated with typical dietary intake of either ingredient.
