【摘要】：初步研究膜分离技术对沙棘籽油的精制效果及考察其适用性.以膜通量、膜污染阻力及油脂理化参数为考察指标,研究不同切割分子量超滤膜及操作条件对沙棘籽油精制效果及其膜过程的影响.实验结果表明,切割分子量30 000的超滤膜适合于沙棘籽油膜精制,其对磷脂的截留率高达90%以上,并能在一定程度上降低油脂的酸值、皂化值,提高沙棘籽油的稳定性.操作压力、转速及溶液浓度对油脂膜精制过程中的膜通量及膜污染程度有着重要的影响.不同操作条件对沙棘籽油的精制效果没有显著性差异.膜分离技术能够应用于沙棘籽油的精制过程,能够达到较好的精制效果,提高沙棘籽油的稳定性.
[Abstract]:The refining effect and applicability of membrane separation technology on seabuckthorn seed oil were preliminarily studied. The membrane flux, membrane fouling resistance and physical and chemical parameters of oil were studied. The effects of different cutting molecular weight ultrafiltration membrane and operating conditions on the refining effect and membrane process of seabuckthorn seed oil were studied. The experimental results showed that the ultrafiltration membrane with molecular weight of 30 000 was suitable for refining seabuckthorn seed oil film. The retention rate of phospholipid is more than 90%, and the acid value and saponification value of oil can be reduced to a certain extent, and the stability of seabuckthorn seed oil can be improved. Rotational speed and solution concentration have important influence on membrane flux and membrane fouling in the process of oil membrane refining. There is no significant difference in refining effect of seabuckthorn seed oil under different operating conditions. Membrane separation technology can be applied to seabuckthorn. The refining process of seed oil, It can improve the stability of Hippophae rhamnoides seed oil.
