What it is

Sodium bisulfite is a chemical compound made from sulfur dioxide and sodium hydroxide. It is commonly used as a preservative and antioxidant in food products. TBHQ (tert-Butylhydroquinone) is a synthetic antioxidant produced from hydroquinone and isobutylene.

Why it's used

Sodium bisulfite and TBHQ are often used together in processed foods to prevent spoilage and maintain color. Sodium bisulfite acts as an antioxidant and antimicrobial agent, while TBHQ is a potent antioxidant that prevents oils and fats from going rancid. They are found in a variety of products, including dried fruits, baked goods, and processed meats.

Health notes

Sodium bisulfite is generally recognized as safe (GRAS) by the FDA when used as a preservative. However, it can trigger allergic-type reactions in sensitive individuals, particularly those with asthma. TBHQ is also approved by the FDA as a food additive. Both substances have been evaluated by international bodies like JECFA and EFSA. While generally considered safe at typical consumption levels, some research has explored potential health effects at very high doses, though evidence is mixed and often based on animal studies.

Allergen info

Neither sodium bisulfite nor TBHQ are derived from any of the 9 major allergens. They do not contain gluten.
