Butylated Hydroxyanisole, commonly known as BHA, is a food preservative that is used in food processing and storage to prevent the oxidation of fats and oils. However, due to the potential health risks associated with BHA, many food manufacturers have sought out alternative preservatives to use in their products. Some of the synonyms for BHA include butylhydroxyanisole, BHA-FEMA, n-butylhydroxyanisole, and butylated hydroxytoluene (BHT), which is a similar preservative that is often used in place of BHA. Other natural preservatives, such as rosemary extract, vitamin E, and ascorbic acid, are also gaining popularity as safer alternatives to BHA.
