Problems solved by technology

However, due to the poor stability of unsaturated fatty acids, they are easily oxidized and produce harmful substances such as aldehydes and ketones, which not only lose their nutritional value, but also have certain toxic effects on the human body. Therefore, it is extremely important to delay the oxidation of fish oil.

Abstract

The invention discloses a natural antioxidant compound for protecting fish oil. The antioxidant compound contains dihydromyricetin, tea polyphenol and vitamin C with a mass ratio of 1:1:1; or dihydromyricetin, rosemary and vitamin C with a mass ratio of 2:3:2; or tea polyphenol, rosemary and vitamin C with a mass ratio of 2:3:2. The invention further discloses a use method of the natural antioxidant compound for protecting fish oil. The compound technology of the three natural antioxidants of dihydromyricetin, tea polyphenol and rosemary is adopted to improve the oxidation resistance of the antioxidant, so as to improve the antioxidant effect.

Description

technical field [0001] The invention belongs to the field of food anti-oxidation, and in particular relates to a natural composite antioxidant for protecting fish oil, and also relates to a method for using the natural composite antioxidant for protecting fish oil. Background technique [0002] Fish oil is rich in n-3 series unsaturated fatty acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), which can prevent myocardial infarction, arrhythmia, reduce blood lipids, and atherosclerosis. Antioxidant scavenging free radicals, anti-aging and other physiological functions. In recent years, the development and utilization of fish oil products has become a research hotspot at home and abroad, and is widely used in food, medicine, feed, chemical and other industries. However, due to the poor stability of unsaturated fatty acids, they are easily oxidized and produce harmful substances such as aldehydes and ketones, which not only lose their nutritional value, ...
