What it is

BHA (butylated hydroxyanisole) and TBHQ (tertiary butylhydroquinone) are synthetic antioxidants. They are man-made chemicals produced through chemical synthesis.

Why it's used

These additives are used to prevent fats and oils in food from spoiling, a process called rancidity. They are often found in foods with fats, such as snack foods, cereals, baked goods, and some frozen desserts like ice cream and sherbet.

Health notes

BHA and TBHQ are approved by the FDA for use as food additives. JECFA has evaluated both BHA and TBHQ and set acceptable daily intakes. The International Agency for Research on Cancer (IARC) has classified BHA as possibly carcinogenic to humans (Group 2B). For TBHQ, some studies have raised questions about its effects, but major food safety authorities, including JECFA, consider it safe at the levels permitted in food.

Allergen info

Not a major allergen.
