Butylated hydroxyanisole powder Usage and Synthesis.

Butyl hydroxyanisole (BHA) is a commonly used antioxidant in edible fats and oils, fried foods, dried fish, cookies, instant noodles, nuts, cured meat foods, etc. Its function is to prevent oxidative deterioration of foods and prolong shelf life.

BHA is quite stable to heat and is not easily destroyed under weak alkaline conditions, and can be used alone or mixed with other antioxidants. However, clinical studies have shown that both BHA and dibutylhydroxytoluene can induce cancer.

Therefore, consumers should pay attention to the BHA content in food ingredient lists and try to choose BHA-free foods.

In the sampling of food additives, butyl hydroxyanisole and tert-butylhydroquinone were predominant in potato and puffed foods.

Therefore, consumers should also pay attention to the BHA content in the ingredient list when purchasing these foods. 

Uses and functions of Butylated hydroxyanisole powder.

Butylated hydroxyanisole is an oil-soluble antioxidant widely used at home and abroad, and the antioxidant capacity of 3-BHA is l.5 to 2 times that of 2-BHA, and the mixture of the two has certain synergistic effect.

The antioxidant effect is more significant when other oxidizing agents are mixed or used with synergist citric acid.

China's regulations can be used in edible fats and oils, fried foods, cookies, instant noodles, quick-cooking rice, canned nuts, dried fish products and preserved meat products, the maximum use of 0.2g/kg (maximum use of fat); mixed with BHT, the total amount shall not exceed 0.2g/kg; mixed with BHT, PG, the total amount of BHA and BHT shall not exceed 0.1g/kg, and the total amount of PG shall not exceed 0.05g/kg. The product also has strong antibacterial effect and is effective against most bacteria and molds.

As a fat-soluble antioxidant, butyl hydroxyanisole is suitable for fat food and fat-rich food. Because of its good heat stability, it can be used under frying or baking conditions.

In addition, butylated hydroxyanisole has a strong antioxidant effect on animal fats and a poor antioxidant effect on unsaturated vegetable fats. Butyl hydroxyanisole can stabilize the pigment of raw beef and inhibit the oxidation of ester compounds.

Butyl hydroxyanisole can be used as feed antioxidant, also has antibacterial effect.BHA dosage of 250mg/kg can inhibit the production of aflatoxin, 200mg/kg BHA can completely inhibit the growth of food and feed growth such as toxin enzyme, Aspergillus niger and other spore growth.

Antioxidant, added to the antioxidant effect of food 3-BHA is 1.5-2 times stronger than 2-BHA, but the mixture of the two has a certain synergistic effect, therefore, the mixture containing a high proportion of 3-BHA, its effectiveness is almost similar to that of pure 3-BHA.

BHA can work with the peroxides produced during the oxidation of fats and oils, so that the chain reaction of automatic oxidation of fats and oils is cut off, preventing the fats and oils from continuing to oxidize.

When BHA is mixed with other antioxidants and synergists such as citric acid, its antioxidant effect is more significant. In addition to the antioxidant effect, BHA also has strong antibacterial power and anti-mold effect.

As a food additive, it is used as an antioxidant in oils and fats, lard, fish and shellfish salt-cured products, dried fish and shellfish products, pretzels, fried potato flakes, instant noodles, fried snacks, etc. It is also used as a feed additive and gasoline additive. It is also used as feed additive and gasoline additive.3-tert-butyl-4-hydroxyanisole (2-BHA) is also used as biochemical reagent.

Pharmacological effect of action of Butylated hydroxyanisole powder.

Product Method of Bulk Butylated hydroxyanisole powder.

(1) Preparation of intermediate p-hydroxyanisole.

It can be produced by alkylation of hydroquinone as raw material, and the synthesis method of p-aminoanisole as raw material is given here: p-aminoanisole and sodium nitrite (molar ratio of 1:1:15) were added into the reactor, and diazotization was carried out in the presence of sulfuric acid. After the reaction is completed, keep warm and filter, and slowly add the filtrate into the hot water for hydrolysis.

The p-hydroxyanisole is immediately distilled out with steam, condensed and extracted with the organic solvent benzene. After concentration and distillation to remove the solvent, the product can be obtained, the average yield of 84.7%.

(2) BHA was synthesized. The solvent benzene, tert-butanol and p-hydroxyanisole were added to the reactor in turn and heated to dissolve, and then added the catalyst phosphoric acid or sulfuric acid, and the reaction was refluxed at 80 ℃ with strong stirring.

After the reaction was completed, the material was discharged and left to stratify. The organic phase was washed successively with 10% sodium hydroxide solution and water to neutral. Remove the solvent by distillation, and then recrystallized by ethanol to get the finished product.
