摘  要:
以多重乳状液相对体积为衡量标准,借助显微镜直接观察,探讨第一相乳化剂含量、第一相质量分数、亲油亲水乳化剂质量比、体系乳化剂的含量等因素对核桃油多重乳状液体系稳定性的影响,并通过正交试验设计优化了乳化工艺。结果表明,第一相质量分数55%,亲油亲水乳化剂质量比7∶1,乳化剂含量11%,第一相核桃油含量66%,体系稳定性最好,相对体积分数达到92.5%。同时,核桃油过氧化值的测量表明,核桃油在多重乳状液中的氧化稳定性较好,并与乳状液体系本身的稳定性相关。

摘  要:
Effects of various factors such as the contents of walnut oil in first phase,the concentration of first phase,mass ratio of hydrophobic emulsifier to hydrophilic emulsifier and the concentration of the emulsifier on the stability of walnut oil W/O/W multiple emulsions were examined by microscopic observation.The optimal extraction conditions were defined by orthogonal design.Results showed that the optimum conditions for the system were the mass fraction of walnut oil in first phase 66%,the mass fraction of the first phase 55%,M(Span80)∶M(Q-12A)7∶ 1,and the mass fraction of the emulsion 11%.The results of peroxide value showed that mult-emulsifier system could improve the oxidative stability of walnut oil.
