摘要
在CTAB／n－C5H(11)OH／H2O体系中，维生素C存在于O／W、W／O液滴的内侧，C5H(11)OH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．
Vitamine C(VC) was solubilized in the inner region in the interphase of O/W andW/O microemulsion, but n-C5H11 OH was solubilited in the outer region.The water pene-trating into the interphase or amphiphilic layer was prevented from VC by n-C5H11OH so thatthe stability of VC was enhanced. The mechanism of enhancing stability of VC in O/W andW/O microemulsion droplets was proved by the enhancing stabllity of VC in lamellar liquidcrystal.
