Freshness Preserved With BHT And Citric Acid

BHT (butylated hydroxytoluene) is a synthetic antioxidant. Citric acid is a weak organic acid found naturally in citrus fruits.

BHT is added to foods to prevent fats and oils from becoming rancid, which preserves freshness and flavor. Citric acid can act as a preservative by lowering pH and as an antioxidant synergist, enhancing BHT's effect. They are often found in snacks, cereals, and baked goods.

BHT is FDA-approved as a food additive. The FDA has determined that BHT is safe for consumption at levels typically found in food. JECFA and EFSA have evaluated BHT and established acceptable daily intakes. Some studies have raised questions about BHT's long-term effects, but regulatory bodies consider it safe at approved levels. Citric acid is generally recognized as safe (GRAS) by the FDA and is widely consumed in foods.
