Introduction
Our company's raw materials Phosphatidylcholine(PC) for PS production are non-GMO soybeans and sunflower seeds. From the product state, we can make liquid PS and PS powder . Liquid PS can be dissolved in oil, suitable for soft capsules, Powder PS has good fluidity, suitable for hard capsules, tablets, and solid beverage powder. Our PS is calcium salt, which is soluble in petroleum ether, chloroform and edible oil. Also Note that the color of high content PS is off-white to white.
Soybean lecithin is obtained by Phospholipase biotransformation, and the reaction mechanism is as follows:：
Our Raw Material Phosphatidylserine powder Feature
● The core technology of PS production is the Phospholipase D produced by our company. Our company has the core technology of producing Phospholipase D, including all the core production technologies of producing Phospholipase D from Streptomyces sp.
● Our PS does not use chemical reagents in the entire enzymatic reaction process, only grain alcohol is used. Products produced by other domestic processes use aromatic hydrogen chemical reagents such as petroleum ether or n-hexane.
● The quality is stable from raw materials to semi-finished products, and the final products are fully monitored.
● We have obtained SC certification for solid beverages, and there is no legal risk for customers to use them.
COA
There are two COA Reports about PS. One is PS 70 powder, the other is PS20% oil COA.
