What it is
BHT (butylated hydroxytoluene) is a synthetic antioxidant. It is made from petroleum-based chemicals. Citric acid is a weak organic acid found naturally in citrus fruits, but the citric acid used in food is typically produced industrially through the fermentation of sugar by microorganisms.
Why it's used
BHT is added to foods to prevent fats and oils from becoming rancid, which helps extend shelf life. Citric acid is used to add a sour taste, act as a preservative, and help other antioxidants work better. They are often found together in processed foods like baked goods, cereals, and snack foods.
Health notes
BHT is Generally Recognized As Safe (GRAS) by the FDA for use as a food additive. Citric acid is also GRAS. Both have been evaluated by international bodies like JECFA and EFSA. While generally considered safe at typical consumption levels, some studies have raised questions about BHT's potential effects, though evidence is mixed and often based on high doses not representative of human intake.
Allergen info
Neither BHT nor citric acid are derived from any of the 9 FDA major allergens. They do not contain gluten.
