BHT (also known as butylated hydroxytoluene) is a commonly used food antioxidant and is widely used in the food sector.
The following are the main applications of BHT in the food field:
Antioxidant: The main function of BHT is to inhibit the oxidation reaction in food and extend the shelf life of food. It can react with free radicals and reduce the oxidation of food by oxygen, thus preventing the deterioration and oxidation of food fats and oils.BHT is often added to foods with high fat content, such as oils, nuts, meat products and pastries, to improve their stability and freshness.
Preservative: BHT also has some antimicrobial effect, which can inhibit the growth of some bacteria and moulds, thus prolonging the shelf life of food. It is often added to some foods susceptible to microbial contamination, such as meat products, sauces, fats and cooked foods, to prevent the growth and reproduction of bacteria and moulds.
Preventing discolouration of food pigments: BHT also prevents discolouration of food pigments during storage and heating. It is often added to foods that need to maintain colour stability, such as meat products, biscuits, confectionery and beverages.
