| 摘 要： | 采用活性炭吸附去除大豆磷脂中的内毒素.以磷脂残留的内毒素浓度和磷脂回收率为指标,考察了活性炭用量、吸附温度、吸附时间对内毒素脱除效果的影响.在单因素试验的基础上,通过正交试验,得到最佳工艺参数:活性炭用量0.6％,吸附时间40 min,吸附温度50℃.在最佳条件下,测得磷脂中细菌内毒素的浓度为11.02×10-3 EU/mL,回收率为89.65％.

| Abstract: | The activated carbon was used to remove the bacterial endotoxin from lecithin.The effects of dosage of activated carbon,adsorption temperature,adsorption time on the residual endotoxin concentration and recovery rate of lecithin were investigated.Based on the results of single factor tests,the orthogonal experiment was utilized to obtain the optimal conditions as follows:dosage of activated carbon 0.6%,adsorption temperature 50 ℃,adsorption time 40 min.Under the optimal conditions,the concentration of bacterial endotoxin of lecithin was 11.02×10-3 EU/mL,and the product recovery rate was 89.65%. |
