butylated hydroxyanisole的意思|示意

Butylated hydroxyanisole, also known as BHA, is a common food additive and preservative. BHA is an antioxidant, meaning it can help prevent food from spoiling by slowing the oxidation process. It is often found in processed foods, such as snacks, crackers, and cereals, as well as in cosmetics, pharmaceuticals, and rubber products.

BHA is used to keep food from going rancid, which happens when oils break down due to oxidation. It works by binding to the free radicals that are responsible for the oxidation process. By binding to these free radicals, it stops them from reacting with other molecules and stops the oxidation process.

BHA is also used in cosmetics and pharmaceuticals as an emollient, meaning it helps to keep the skin moist and soft. It also has anti-inflammatory properties, which can help reduce redness, irritation, and inflammation.

BHA is generally considered safe to use. It is approved by the FDA as a food additive and has been deemed safe by the U.S. Environmental Protection Agency. However, long-term exposure to large amounts of BHA has been linked to an increased risk of cancer in animals. Therefore, it is important to use caution when consuming products containing BHA.
