Butylated hydroxytoluene (BHT), also known as dibutylhydroxytoluene, is a lipophilic organic compound, chemically a derivative of phenol, that is useful for its antioxidant properties. European and U.S. regulations allow small amounts to be used as a food additive.
BHA or butylated hydroxyanisole [pdf] is a synthetic antioxidant that is used to prevent fats in foods from going rancid and as a defoaming agent for yeast. First synthesized in the late 1940s, the compound began being used as a food additive around 1947. BHT or butylated hydroxytoluene [pdf] also stabilizes fats and is used to retain food smell, color and flavor. It too appeared on the synthetic chemical scene in the late 1940s and was used as a food additive beginning in 1954 [pdf]. (See also here.)
