What it is
Sorbic acid is a naturally occurring compound found in some plants, like rowan berries. It is commercially produced through a chemical process, often starting with petrochemicals. It is used as a food preservative to prevent the growth of mold, yeast, and some bacteria.
Why it's used
Sorbic acid and its salts (like potassium sorbate) are widely used as preservatives in a variety of foods. They help extend shelf life by inhibiting spoilage microorganisms. You can find them in baked goods, cheese, dried fruits, wine, and processed meats like sausages and hot dogs.
Health notes
In the United States, sorbic acid is generally recognized as safe (GRAS) by the FDA when used as a food additive. International bodies like JECFA and EFSA have also evaluated sorbic acid and its salts, establishing acceptable daily intake levels. Studies on sorbic acid generally show it to be well-tolerated at typical dietary levels, with minimal reported adverse effects. Some individuals may experience skin reactions or digestive upset, though this is uncommon.
Allergen info
Sorbic acid is not derived from any of the 9 FDA major allergens and does not contain gluten.
