Problems solved by technology

Among them, the extraction method requires a large amount of animal tissue, and the extraction process uses more solvents, the efficiency is low, the separation and purification process is complicated, and the separation is difficult; the bio-enzyme-catalyzed synthesis method can synthesize phosphatidylserine in batches
The disclosed enzymatic synthesis methods all use relatively high-purity phosphatidylcholine as a raw material to synthesize phosphatidylserine, and there are high reaction temperatures, long reaction cycles, low yields, high boiling point solvent residues, and easy inactivation of enzymes, etc. shortcoming

Abstract

The invention relates to the technical field of production and preparation of phosphatidylserine, in particular to a method for quickly and stably preparing phosphatidylserine for foods. The method comprises the following steps: A, dispersing phospholipase D in an ionic liquid, so as to obtain a mixed system; B, adding soybean lecithin and serine into the mixed system, and performing standing, so as to obtain the phosphatidylserine. According to the method, by use of the ionic liquid, the phospholipase is high in catalytic activity and stability to temperature; the soybean lecithin and the serine are added into the ionic liquid, and then an emulsifier is also added; via ultrasonic treatment, the phospholipase D can be quickly and catalytically synthesized in the ionic liquid, therefore, the phosphatidylserine is formed; the reaction time is short, and the yield is high. The product is suitable for being added into health foods such as milk and drink and has outstanding effects of preventing low cognitive ability and relieving the 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 ...
