Abstract

A powdered or granulated phospholipid compsn. (I) with phosphatidylcholine content at least 80 wt.%, is free from additives. (I) is pref. crystalline, with crystal size 18-0.07mm (6-0.5mm), and with more than 80 (more than 90) wt.% of crystalline phosphatidylcholine components. Esp., it contains 90-96 wt.% of phosphatidylcholine and 0-6% of lysophosphatidylcholine. (I) is prepd. by grinding the phospholipid compsn. with cooling, at below -50 deg.C, opt. after storage at between +5 and -60 deg.C (esp. between 10 and -30 deg.C), partic. for 1-150 (30-70) days. Grinding and/or storage are under an inert gas, esp. N2, CO2 and/or a noble gas. The phospholipid compsn. has been isolated from soya lecithin and contains 90-96 wt.% of phosphatidylcholine. After storage and before grinding, the temp. is brought to room temp. (I) is stored at below 10 (1-6) deg.C, pref. under an inert gas.
