BHT And Mixed Tocopherols Added To Retain Freshness

BHT (butylated hydroxytoluene) is a synthetic antioxidant. Mixed tocopherols are a form of vitamin E, which can be naturally derived from sources like soybeans or corn, or synthesized. They are often used together to prevent fats and oils in food from becoming rancid.

These ingredients are added to foods to prevent spoilage and maintain freshness by acting as antioxidants. They protect fats and oils from oxidation, which can cause off-flavors and odors. They are commonly found in cereals, snack bars, and other processed foods containing fats.

BHT and mixed tocopherols are permitted food additives in the US. The FDA lists BHT as GRAS (Generally Recognized As Safe) when used as a preservative. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated BHT and set an acceptable daily intake. While some studies have raised questions about BHT's long-term effects, regulatory bodies generally consider it safe at typical consumption levels. Mixed tocopherols are a form of vitamin E and are considered safe.
