Antioxidants To Maintain Freshness

Antioxidants are compounds that inhibit oxidation, a chemical reaction that can degrade food and lead to spoilage. They are often naturally occurring in foods like fruits and vegetables, but can also be synthesized. Common examples include BHA, BHT, and TBHQ.

Manufacturers add antioxidants to foods to prevent fats and oils from becoming rancid, which helps maintain flavor, color, and overall freshness. They are frequently used in products containing fats, such as cereals, popcorn, nuts, seeds, baked goods, and processed meats.

Antioxidants used for food preservation are regulated by the FDA. Some, like BHA and BHT, are approved food additives, while others may be Generally Recognized As Safe (GRAS). International bodies like JECFA and EFSA have evaluated these substances. Research on the health effects of synthetic antioxidants at typical consumption levels has yielded mixed results, with some studies suggesting potential benefits and others raising concerns that require further investigation.
