What it is
Sodium bisulfite is a chemical compound used as a preservative. It is made by combining sulfur dioxide with a sodium compound. Butylated hydroxytoluene (BHT) is a synthetic antioxidant, a type of preservative, made from petroleum-based chemicals.
Why it's used
Sodium bisulfite and BHT are often used together as preservatives in processed foods. Sodium bisulfite prevents browning and spoilage in dried fruits, wines, and some processed vegetables. BHT prevents fats and oils from going rancid, extending the shelf life of many processed foods, including cereals, baked goods, and snack foods.
Health notes
Sodium bisulfite is generally recognized as safe (GRAS) by the FDA when used as a preservative, though it can cause allergic-type reactions in sensitive individuals. BHT is also FDA approved as a food additive. Both have been evaluated by international bodies like JECFA and EFSA. Some studies have raised questions about the long-term effects of BHT, but regulatory agencies consider it safe at typical levels of consumption.
Allergen info
Neither sodium bisulfite nor BHT are derived from any of the nine major allergens. They do not contain gluten.
