BHT For Freshness

Butylated hydroxytoluene (BHT) is a synthetic antioxidant. It is produced through a chemical process involving p-cresol and isobutylene. BHT is a waxy, white solid.

BHT is added to foods to prevent fats and oils from becoming rancid, which helps extend shelf life. It is commonly found in cereals, crackers, and other processed foods that contain fats.

In the US, BHT is generally recognized as safe (GRAS) by the FDA for use as a food additive. Regulatory bodies like JECFA and EFSA have evaluated BHT. Some studies have raised questions about its long-term effects, but research results are mixed, and evidence at typical consumption levels is not conclusive.
