Soybean Phosphatidylserine PS Powder 50%

Our 50% phosphatidylserine (PS) powder is produced from non-GMO soybean lecithin via enzymatic transphosphatidylation using Phospholipase D enzyme, converting phosphatidylcholine (PC) into phosphatidylserine with L-serine substrate. It is a plant-sourced phospholipid, replacing old bovine-derived PS to eliminate BSE risk.

This soybean-origin PS has decades of commercial and clinical research history. Although the core PS molecule is bioequivalent to sunflower-sourced PS, soybean PS carries a distinct fatty acid profile dominated by palmitic and oleic fatty acids, different from sunflower lecithin lipid composition. It is suitable for mass production cognitive supplements, sports nutrition and stress management formulations.

Manufacturing process: Raw soybean lecithin screening → enzymatic catalytic reaction → membrane separation → purification → vacuum low-temperature drying → milling → sterile packaging. Strict control for n-hexane solvent residue (<10 mg/kg). Batch traceability system covers soybean planting batch, enzyme raw material, production log and finished QA testing.
