摘要: 以蜂胶醇提物为原料,橄榄油为食品级油相,吐温80为表面活性剂,无水乙醇为助表面活性剂,在确定最佳配比的基础上制备O/W型蜂胶纳米乳液,研究了不同均质压力参数(0,40,80 MPa)设定条件下乳化液的平均粒径与分布情况。研究结果表明,均质压力对乳化液的平均粒径与分散指数具有显著影响,经80 MPa高压均质处理所得的乳化液粒子平均直径为(1432±1.4)nm,且粒径分布均一,具有较好的稳定性。

Abstract: In this study,propolis ethanol extract was used as raw material while olive oil as food grade oil phase,Tween 80 as surfactant,and alcohol as cosurfactant. The propolis oil-in-water nano-emulsion was prepared on the basis of determining the best ratio of the above materials. The mean particle size and distribution of emulsions prepared with different homogenization pressure(0,40,80MPa)were analyzed. As shown in the results,the effects of homogenization pressure on particle size and polydispersity index were significant. The emulsion processed under 80 MPa contained (143.2±1.4) nm of average diameter,uniform size distribution and good stability.
