摘要: 为了获得稳定的诺丽精油(Noni essential oil,NEO)水包油型(O/W型)微乳液,本研究采用水滴定法,结合拟三元相图法,考察聚氧乙烯非离子表面活性剂、助表面活性剂、Km值(表面活性剂与助表面活性剂的质量比)、组分及比例对微乳液形成的影响,并测定NEO微乳液的粒径、构型、电导率、水溶性、稳定性及抑菌活性,确定其表征与理化性状。结果表明,当蓖麻油聚氧乙烯40为表面活性剂,丙三醇为助表面活性剂,Km为3,诺丽精油与混合表面活性剂质量比为7∶3,O/W型水相的含水量为70%时,形成的微乳稳定、透明澄清,并伴有蓝光,且平均粒径在(25.88±4.82) nm,PDI为0.177±0.030,微乳粒子分散均匀,呈球状和类球状。同时,NEO微乳具有良好的贮藏稳定性、离心稳定性和盐离子浓度稳定性,适宜在偏酸性环境下以及40 ℃及以下使用。NEO微乳液对热带假丝酵母菌的抑菌作用优于NEO。本研究表明微乳液可以实现诺丽精油的纳米包覆,为后续诺丽精油在食品、日化品相关领域中的抑菌、防腐等方面开发和应用提供良好的基础。

Abstract:

In order to obtain stable oil-in-water (O/W) microemulsion of Noni essential oil (NEO), the water titration method and the pseudo ternary phase diagram method were used to investigate the effects of polyoxyethylene nonionic surfactants, co-surfactants, Km value (the mass ratio of surfactant to co-surfactant), components, and proportions on the microemulsion formation. Meanwhile, the particle size, morphology, electrical conductivity, water solubility, stability, and antifungal activity of the NEO microemulsion were measured to determine their characteristics and physicochemical properties. The results show that castor oil polyethylene glycol 40 as the surfactant, propylene glycol as the co-surfactant, and Km with 3 when the mass ratio of NEO to the mixed surfactant is 7∶3, the water content of the O/W type aqueous phase is 70%, and the NEO microemulsion can be formed. The microemulsion is stable, transparent, and clear with a blue tint. The average particle size is (25.88±4.82) nm with the PDI of 0.177±0.030, and the microemulsion particles are more uniformly dispersed, spherical, and nearly spherical. At the same time, NEO microemulsion has good storage stability, centrifugal stability, and ion concentration stability, and is suitable for use at temperatures below 40 ℃ and in slightly acidic environments. The antifungal effect of NEO microemulsion on Candida tropicalis is better than that of NEO. This study shows that the microemulsion can achieve nanoparticle encapsulation of NEO, providing a good foundation for the widespread application of NEO.
