摘要
通过离心提取新鲜大豆油脚的中层分离物,将其与丙酮充分混合,经减压抽滤、真空干燥得到大豆磷脂并对该过程提取条件进行了优化.结果表明,最佳提取条件为离心转数5 000 r/min,磷脂与丙酮的体积比为1∶6,丙酮洗涤3次,得到相对质量分数为86.78%的大豆磷脂.
Soybean phospholipid was obtained by centrifuging,adding acetone to the center part,sucking filtration,and vacuum drying from the fresh soybean oil sediments.The results showed that the optimal parameters of a orthogonal optimize experiments are as fellows centrifuge speed is 5 000 r/ min,volume ratio of soybean phospholipid and acetone is 1∶6,the production was washed three times with acetone.The relative amount of lecithin had achieved 86.78%.
