Uses and synthesis of Butylated hydroxyanisole powder

Butylated hydroxyanisole powder White to yellowish crystalline or waxy solid with a slight odor. Melting range 48 ~ 63℃. Boiling point 264 ~ 270℃(97709Pa). It is yellow-brown in long-term storage. It can be compressed into a cylinder weighing a few grams. Insoluble in water; Butylated hydroxyanisole is an oil-soluble antioxidant widely used at home and abroad. The antioxidant capacity of 3-BHA is l.5 ~ 2 times that of 2-BHA, and the mixture of the two has a certain synergistic effect. Mixed with other oxidants or combined with citric acid, the antioxidant effect is more significant. Our country stipulates Butylated hydroxyanisole powder can be used for edible oil and deep-fried foods, biscuits, instant noodles, instant cooking rice, canned nuts, dried fish products and cured meat products, the maximum amount of 0.2g/kg(maximum amount to exfoliate);

Applications/Functions of Butylated hydroxyanisole powder

1. Butylated hydroxyanisole powder, as a fat-soluble antioxidant, is suitable for fatty foods and fat-rich foods.
2. The antioxidant effect of 3-BHA added to food is 1.5-2 times stronger than 2-BHA, but the mixture of the two has a certain synergistic effect, so the mixture containing a high proportion of 3-BHA has a potency almost similar to that of pure 3-BHA.
3. Butylated hydroxyanisole is used as a food antioxidant
4. Butylated hydroxyanisole can be used as a feed antioxidant and also has antibacterial effects. The dosage of BHA 250mg/kg can inhibit the production of aflatoxin, 200mg/kgBHA can completely inhibit the growth of food and feed such as toxic enzymes, Aspergillus Niger and other spores.
