Food additive BHA function

Butyl hydroxyl bai anisole (BHA), white or yellowish du crystal, melting point 48-63 ℃, boiling point 264-270 ℃ (98 KPa), high concentration is slightly phenolic, soluble in ethanol (25 g mL,25), propylene glycol and oil, insoluble in water.

BHA is thermally stable, not easy to be destroyed under weak alkali conditions, and does not color when it interacts with metal ions. BHA is a good antioxidant and has no toxicity at its effective concentration.

As a food antioxidant, it can hinder the oxidation of fatty food and delay the time when the food begins to spoil. The maximum amount of its in food should not exceed 0.2g/kg in terms of fat. When the dosage is 0.02%, the antioxidant effect is 10% higher than that of 0.01%, and when the dosage is more than 0.02%, the antioxidant effect decreases. When used as antioxidants in cosmetics, it can play an antioxidant role in acids, hydroquinone, methylthio amino acids, lecithin and sulfurized dipropionic acid. It can also be used as an antioxidant in feed.

As a fat-soluble antioxidant, BHA is suitable for fatty foods and fat-rich foods. Because of its good thermal stability, it can be used under the condition of frying or baking. In addition, BHA has strong antioxidant effect on animal fat, but poor antioxidant effect on unsaturated vegetable fat. BHA can stabilize the pigment of raw beef and inhibit the oxidation of esters.

BHA combined with sodium tripolyphosphate and ascorbic acid can delay the spoilage of frozen pork chops.

BHA can slightly prolong the shelf life of spray-dried whole milk powder and improve the shelf life of cheese.

BHA can stabilize the color of chili and chili powder and prevent the oxidation of foods such as walnuts and peanuts.

BHA is added to baking oil and salt to maintain the aroma of baked goods and salty peanuts. Extend the shelf life of baked goods.

BHA can be mixed with other fat-soluble antioxidants for better results. For example, BHA and dibutylhydroxytoluene can protect carp, chicken, pork chops and frozen smoked pork slices.

BHA or a mixture of dibutylhydroxytoluene, propyl gallate and citric acid are added to the butter used to make candy to inhibit the oxidation of candy.
