摘要： 在CTAB/n－C5H11OH/H2O体系中,维生素C存在于O/W、W/O液滴的内侧,C5H11OH则存在于液滴的外侧,阻碍了渗透进入膜相中的水与维生素C的接触,从而大幅度降低了维生素C在水体系中的氧化程度,提高了其稳定性.O/W、W/O微乳液对维生素C分子增稳作用的机理亦从层状液晶对其增稳作用中得到证明.

关键词: 维生素C, 表面活性剂, 层状液晶

Abstract: Vitamine C(VC) was solubilized in the inner region in the interphase of O/WandW/Omicroemulsion, but n-C5H11 OHwas solubilited in the outer region.The water pene-trating into the interphase or amphiphilic layer was prevented from VCby n-C5H11OHso thatthe stability of VCwas enhanced.The mechanism of enhancing stability of VCin O/WandW/Omicroemulsion droplets was proved by the enhancing stabllity of VCin lamellar liquidcrystal.

Key words: Vitamine C, Surfactant, Lamellar liquid crysted
