A method for rapidly and stably preparing phosphatidylserine for food

Abstract

The present invention relates to the technical field of production and preparation of phosphatidylserine, in particular to a method for rapidly and stably preparing phosphatidylserine for food, comprising the following steps: A, dispersing phospholipase D in an ionic liquid to obtain a mixed system; B, Add soybean lecithin and serine into the mixed system and let it stand to obtain phosphatidylserine; the present invention makes the enzyme have good catalytic activity and temperature stability through ionic liquid, adds soybean lecithin and serine to the ionic liquid, and adds emulsifying Agent, through ultrasonic treatment, phospholipase D quickly catalyzes the synthesis in ionic liquid to form phosphatidylserine, the reaction time is short and the yield is high. The product is suitable to be added to health foods such as milk and beverages, and has significant effects on preventing cognitive impairment and alleviating fatigue.

Description

technical field

[0001] The invention relates to the technical field of production and preparation of phosphatidylserine, in particular to a method for rapidly and stably preparing phosphatidylserine. Background technique

[0002] Phosphatidylserine (PS), also known as compound nervous acid, its main function is to improve the function of nerve cells, regulate the conduction of nerve impulses, and improve the memory function of the brain. Because of its strong lipophilicity, it can quickly pass through the blood brain after absorption The barrier enters the brain, plays a role in soothing vascular smooth muscle cells and increasing blood supply to the brain. Whether it is used as a medicine or a health food, there is no doubt that phosphatidylserine supplementation can improve long-term memory, long-term cognition, and the ability to speak freely and logically.

[0003] Phosphatidylserine (PS) has become the subject of clinical trials in many European and American countries ...
