超高压均质制备辣木籽油纳米乳液及稳定性

Preparation and Stability of Moringa oleifera Seed Oil Nanoemulsion by Super High-Pressure Homogenization

为采用超高压均质制备辣木籽油纳米乳液,研究均质压力、辣木籽油用量、蔗糖脂肪酸酯用量对纳米乳平均粒径的影响,通过正交试验优化制备条件并对辣木籽油纳米乳液的稳定性进行评价。结果表明:制备的最佳工艺参数为:均质压力160 MPa、辣木籽油用量8%、蔗糖脂肪酸酯用量0.6%,最小粒径为142.32 nm。制备的纳米乳液具有较好的离心稳定性和储藏稳定性,表明超高压均质是制备辣木籽油纳米乳液适宜的方法。

In order to preparation Moringa oleifera seed nanoemulsion by super high-pressure homogenization,the effects of pressure,dosage of seed oil,dosage of sucrose fatty acid ester on emulsion average particle size were studied.The preparation condition was optimized by orthogonal experiment,and the stability of seed oil nanoemulsion was preliminary evaluated.The results showed that the optimal parameters were pressure 160 MPa,dosage of seed oil 8%and dosage of sucrose fatty acid ester 0.6%.The minimum particle size was 142.32 nm.Nanoemulsion had better centrifugal stability and storage stability.Sosuper high-pressure homogenization was a suitable method for preparation of Moringa oleifera seed nanoemulsion.
