Dried fish products antioxidant TBHQ
the product and cause great harm to human health. Researchers have been committed to exploring efficient antioxidant technologies and developing safe products. The successful development and widespread use of antioxidants such as TBHQ have solved the problem of rancidity in oil-rich foods. TBHQ, BHA, BHT, PG, etc. are all free radical absorbents that can transform free radicals into stable products and block free radical chain reactions. In the study, it was also found that the antioxidant effect of TBHQ is 5-7 times that of other antioxidants, because their stability is different after reacting with peroxides.
Using isobutylene as an alkylation reagent requires a reaction under closed conditions, which can also be catalyzed by strong acids. In a mixed solvent of xylene and ketone, 85% phosphoric acid is used as a catalyst [8], and isobutylene is added to synthesize tert butylhydroquinone. The selectivity of the single tert butylation reaction can reach over 90%. Cationic resin [9] can also serve as a catalyst for this reaction, but the effect is not very ideal.
Product Description
In addition, TBHQ also has characteristics such as high temperature resistance, oil solubility, and antibacterial properties, which are widely used in edible oils, fried foods, etc. By comparing the effects of various antioxidants in different products, summarizing the usage patterns, and providing theoretical basis for the application of TBHQ.
The oil in oily food undergoes oxidation in the air, producing free radicals and peroxides, which are early indicators of food rancidity. Peroxides further decompose to form small organic compounds such as aldehydes, ketones, and acids, which directly affect the taste and flavor of the product and cause great harm to human health. Researchers have been committed to exploring efficient antioxidant technologies and developing safe products. The successful development and widespread use of antioxidants such as TBHQ have solved the problem of rancidity in oil-rich foods.
The national hygiene standard number is GB276090.4007.
The safety of TBHQ has been comprehensively reported, and its acute toxicity belongs to low toxicity level. It has not been found that it accumulates in the body tissue and has no significant impact on the development and genetics of rats, and no carcinogenic mutations have been observed.
