Butylated Hydroxyanisole (BHA) is a synthetic antioxidant that has been widely used as a food additive since the mid-20th century. Its primary function is to prevent the oxidation of fats and oils in food products, thereby extending their shelf life and preventing the development of rancid flavors and odors. The BHA food preservative role is critical in maintaining the quality and safety of many processed foods.

BHA is classified as a food additive and is often referred to by its E number, E320, in European countries. In the United States, the Food and Drug Administration (FDA) has deemed BHA generally recognized as safe (GRAS) for use in food within specified limits. However, ongoing scientific research continues to evaluate the safety of food additives, including BHA. While it is effective at low concentrations, some studies, particularly those involving high doses in animal models, have raised questions about its potential health effects, including carcinogenicity.

The what is BHA antioxidant aspect is central to its function. By acting as a free radical scavenger, BHA protects foods from oxidative damage. This is particularly important for products with a high fat content, such as processed meats, snacks, and baked goods. Its inclusion in food packaging also helps preserve the quality of the food it protects.

The regulatory landscape surrounding BHA varies globally, with different countries having different guidelines on its use and concentration limits. Consumer awareness and scientific research are driving discussions about the long-term safety and potential health impacts of BHA. For consumers seeking to make informed choices, understanding the role of BHA in food products is paramount. The availability of alternatives, such as Vitamin E, is also a topic of discussion as the food industry evolves.

For those involved in food production and quality control, sourcing high-quality BHA is essential. Understanding the BHA price and finding reliable BHA suppliers ensures that products meet both quality and regulatory standards. The compound's CAS 25013-16-5 identifier is crucial for precise identification in chemical databases and sourcing.
