BHT Added To Packaging Material To Help Preserve Freshness

Butylated hydroxytoluene (BHT) is a synthetic antioxidant. It is a petroleum derivative that is manufactured through chemical synthesis. BHT is a waxy, white solid.

BHT is added to foods and packaging materials to prevent fats and oils from going rancid, thus preserving freshness. It is commonly found in cereals, snack foods, and processed meats. It is also used in some chewing gum and baked goods.

BHT is generally recognized as safe (GRAS) by the FDA for use as a food additive. It is also approved as a direct food substance affirmed as GRAS. JECFA has evaluated BHT and established an acceptable daily intake. Some studies have raised questions about potential health effects, but regulatory bodies like the FDA consider it safe at typical consumption levels. More research is ongoing.
