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,探讨油水相质量比、亲油亲水乳化剂质量比、乳化剂的HLB值、乳化剂的含量等因素对共轭亚油酸多重乳状液体系稳定性的影响。结果表明,单一乳化剂体系中,以Tween80作亲水乳化剂制备的多重乳状液稳定性较好。当m(内水相)∶m(油相)∶m(外水相)=1∶5∶1.3,m(Span80)∶m(Tween80)=9,乳化剂的含量为9.7%时,多重乳液相对体积达到93%。复合乳化剂体系中,在第一相的HLB值为7.4,m(复合乳化剂)∶m(Tween80)=9,乳化剂质量分数为6.67%时,稳定性最好。Effects of various factors such as oil to water ratio, mass ratio of hydrophobic emulsifier to hydrophilic emulsifier, the value of HLB of the emulsifier and the concentration of the emulsifier, on the stability of conjugated linoleic acid W/O/W multiple emulsions were examined by microscopic observation. Results showed that the optimum conditions for solo emulsifier system are rn （Span80） ： m （Tween80）=9, the mass fraction of the emulsifier in the emulsion is 9.7%, the oil to water mass ratio is 5 in first phase, and the mass ratio of first phase to second phase is 6 ： 1.3. The optimum conditions for complex emulsifiers system are： HLB of the emulsifier in the first phase is 7.4, m （mult-emulsifiers） ： m （Tween80）-9, and the mass fraction in the emulsion is 6.67%0.
