Butylated hydroxyanisole (BHA) is a common food additive that is widely used in oils and oily foods, such as biscuits, pastries, fried foods, etc. BHA mainly acts as an antioxidant to prevent the oxidation and deterioration of oils and fats in food and prolong the shelf life of food.
1. Chemical properties.
Butyl hydroxyanisole is a white or yellowish crystalline powder with a slight fragrance. It is a phenolic compound with the molecular formula C11H16O2 and a relative molecular weight of 17625。BHA is easily soluble in oil and insoluble in water. It has high thermal stability, is not easy to decompose at high temperatures, and can effectively inhibit the oxidative deterioration of oils and fats in food under high temperature conditions.
2. Antioxidant effect.
BHA, as a food antioxidant, inhibits oil oxidation primarily by trapping free radicals. Adding an appropriate amount of BHA to food can effectively extend the shelf life of food, prevent oxidation and deterioration of oils and fats in food, and maintain the nutritional value and taste of food.
3. Security.
BHA is a food additive that has undergone extensive safety evaluation and has been widely used for decades. In accordance with food safety regulations in countries around the world, the use of BHA is strictly limited to ensure the health and safety of consumers.
Fourth, how to use.
BHA is usually added to food in powder form in the amount used depending on the type of food and processing conditions. In general, the use of BHA is low, usually 001%-0.02% of the added amount. When using BHA, it should be evenly dispersed in food oils and fats to ensure its antioxidant effect.
V. Conclusions. As an effective food antioxidant, butylated hydroxyanisole is widely used in oils and oily foods. It has high thermal stability and antioxidant properties, which can effectively extend the shelf life of food and maintain the nutritional value and taste of food. When using BHA, the dosage and conditions of use stipulated in food safety regulations should be strictly adhered to to ensure the health and safety of consumers.
