What is bht meaning?

BHT stands for Butylated Hydroxytoluene, which is a synthetic antioxidant that is commonly used as a food preservative. It is used to prevent spoilage and rancidity in foods that contain fats and oils, such as snack foods, baked goods, and other processed foods. BHT is also widely used in cosmetics, pharmaceuticals, and industrial applications. While BHT has been deemed safe for consumption by the FDA and other regulatory bodies, some studies have suggested that high doses may have negative health effects.
