摘要
以大豆磷脂为原料,研究了乳酸加入量、双氧水加入量、反应温度和反应时间4个因素对磷脂羟基化改性的影响。通过正交试验确定了磷脂羟基化改性的最佳合成工艺条件:乳酸加入量为2%、双氧水加入量为20 m L/100 g磷脂、反应温度为70℃、反应时间为2 h。在最佳工艺参数条件下,羟基化磷脂的碘值由原来的91.7降低至37.6。研究结果对于工业化生产羟基化改性大豆磷脂具有重要的理论和实际意义。
The hydroxylated modification of soybean phospholipids was studied in this paper. The influencing factors, such as the amount of lactic acid, the amount of 30% hydrogen peroxide, temperature and the reaction time were determined through single factor tests and the process parameters were optimized by an orthogonal experiment. The results showed that in the presence of 2% lactic acid as catalyst, the hydroxylated phospholipids were obtained in the reaction of soybean phospholipids and 20 mL/100 g soybean phospholipids for 2 h at the temperature of 70℃. The iodine value of the hydroxylated phospholipids was reduced from 91.7 to 37.6. The results have theoretical and practical importance for the industrial production of hydroxylated soybean phospholipids.
