Fish oil antioxidant TBHQ
At present, the production of tert butyl hydroquinone both domestically and internationally adopts the tert butylation method of hydroquinone, as shown in Figure 2. According to different classifications of alkylation reagents, it can be divided into tert butyl method, isobutylene method, and MTBE method. Due to the high toxicity of MTBE to human beings and the environment, this method is almost limited to theoretical research in the laboratory and cannot be promoted in industrial applications.
When the tert butanol process encounters bottlenecks, replacing tert butanol with isobutene is a feasible breakthrough direction. Patent [10] discloses a method for preparing 2-tert butylhydroquinone and co producing BHA using isobutene as an alkylation reagent, which has good selectivity and high raw material utilization rate.
Fish oil is rich in. A 3 polyunsaturated fatty acids, especially eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), with brain health, prevention and treatment of cardiovascular disease and anti-inflammatory, cancer prevention and other efficacy, fish oil products have been more and more used in medicine and health food.
According to the study, when fish oil is stored at room temperature without TBHQ, the time to reach the hygienic limit of peroxide value (POV) of fish oil is 13 days, while the time to reach this value after adding TBHQ is about 80 days.
Fats and oils are one of the basic nutrients in human diet, most of the foods are rich in fats and oils, it can be said that human health cannot be separated from fats and oils, the quality and safety of fats and oils are closely related to human health. However, the chemical nature of fats and oils is very easy to deteriorate due to oxidation and other factors. Fats and oils antioxidants are a class of substances that can prevent or delay the deterioration of fats and oils or fats and prolong their shelf life.
