摘　　要：以葵花油水化油脚脱水制得的葵花油浓缩磷脂为原料,经正己烷除杂和过氧化氢氧化脱色制备精制葵花油浓缩磷脂.结果表明:在料液比为1∶12的条件下,葵花油浓缩磷脂的正己烷不溶物由2.13%降低到0.06%;采用过氧化氢对葵花油浓缩磷脂化学脱色的最佳反应条件为:30%H2O2溶液添加量5%、反应温度55℃、反应时间50 min,可得到加特纳色标值为6.0的葵花油浓缩磷脂,脱色后葵花油浓缩磷脂的酸价由23.4 mg/g升高到26.9 mg/g.In this paper, the refined sunflower phospholipid was made from concentrated sunflower phospholipid extracted from hydrated oil foot of sunflower oil by n-hexane purification and hydrogen peroxide bleaching. The results showed： the n-hexane insoluble in the concentrated sunflower phospholipid was reduced from 2.13% to 0.06% when the material-to-liquid ratio was 1：12; and the optimal hydrogen peroxide bleaching conditions of the concentrated sunflower phospholipid were as follows： 30% H2O2 5%, reaction temperature 55℃, and reaction time 50 minutes. The concentrated sunflower phospholipid processed under the optimal bleaching conditions had a Gartner color of 6.0, and the acid value was increased from 23.4 mg/g to 26.9 mg/g.
