【摘要】 本文根据大豆磷脂的物化性质,研究出精制卵磷脂的新工艺,成功进行了中试放大,并建立了年产50TPC-60的生产线。该方法以粉末磷脂(卵磷脂含量约17%)为原料,在固液比为1∶8、溶剂含水量为5%的条件下,搅拌溶解30min,抽滤、真空干燥母液,制得PC-60卵磷脂产品,产品得率为32%,产品中PC含量为67.9%。更多还原

【Abstract】 Anewmethodwas establishedtopurif yphosphatidylcholine(PC)accordingtotheproperties ofsoybean lecithin.Good results were obtained in the enlarge examinations.A PC pr oducts line,which capability is 50T PC -60per year,was established usin g this method.In this method,PC -60p roducts were obtained from phospholipid powder(the content of PC is about 17%)by the progress below:solvent conta ined 5%water was added into the phospholipid powder w ith the ratio of powder to solvent 1∶8,stirred about 30minutes,filtrate d,evaporated and PC -60products were g otten.The yield of PC -60was 32%and t he content of PCwas 67.9%.更多还原
