Abstract

The invention discloses a method of preparing bioactive phospholipid from tuna eyes. The method includes: subjecting tuna eyes as a raw material to low temperature homogenization, extracting lipid oftuna eyes at room temperature by means of ultrasonic-assisted ethanol extraction, carrying out low-temperature low-pressure distillation to obtain a lipid component, subjecting the lipid to chromatography on silica gel columns, eluting with dichloromethane, acetone and methanol successively, collecting methanol eluate, and carrying out molecular distillation to obtain tuna eye active phospholipid.The method helps promote the benign development of the tuna processing industry and enrich the markets of marine bioactive lipids, and is positively significant to the human health and the development of marine health food industry.

Description

technical field

[0001] The invention relates to the technical field of food processing, in particular to a method for preparing phospholipids with high biological activity from tuna eyes. Background technique

[0002] Tuna is mainly distributed in the vast waters of the Pacific Ocean, the Atlantic Ocean and the Indian Ocean. It is a long-distance migratory pelagic economic fish. The annual tuna catch in my country is about 80,000 tons, and 50%-70% of the actual waste is produced according to processing. According to data calculation, there are about 40,000-56,000 tons of tuna scraps per year. Among these scraps, the eye part of tuna is the part with the highest lipid content, including a large amount of active phospholipid components. Phospholipids are rich in unsaturated fatty acids such as EPA and DHA. These phospholipids have good biological activity on improving memory and improving metabolic syndrome.

[0003] At present, the utilization of tuna lipids is only used to...
