Feb 1, 2011 · BHA (butylated hydroxyanisole) and BHT (butylated hydroxytoluene) are widely used by the food industry as preservatives, mainly to prevent oils in foods from oxidizing and becoming rancid. Oxidation affects the flavor, color and odor of foods and reduces some nutrients.

BHA (butylated hydroxyanisole) and BHT (butylated hydroxytoluene) are both synthetic antioxidants commonly used in the food industry to prevent spoilage and extend the shelf life of products. While they have similar functions, there are some differences between the two.

BHA consists of a mixture of two isomeric organic compounds, 2- tert -butyl-4-hydroxyanisole and 3- tert -butyl-4-hydroxyanisole. It is prepared from 4-methoxyphenol and isobutylene. The conjugated aromatic ring of BHA is able to stabilize free radicals, sequestering them.
