With BHT And Citric Acid To Help Protect Flavors

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 it is typically produced industrially through the fermentation of sugar by mold.

BHT and citric acid are often used together in packaged foods to help protect flavors and prevent spoilage. BHT acts as an antioxidant, slowing down the process of oxidation which can cause fats to go rancid and flavors to change. Citric acid can enhance the effectiveness of antioxidants and also contributes a tart flavor. They are commonly found in baked goods, cereals, and snack foods.

BHT is an FDA-approved food additive. The FDA has also affirmed citric acid as Generally Recognized As Safe (GRAS). Both substances have been evaluated by international bodies like JECFA. While generally considered safe at typical levels, some studies have raised questions about potential health effects of BHT at very high doses, though evidence is mixed and not conclusive. Regulatory bodies continue to monitor scientific research on these ingredients.
