摘　　要：以牡丹籽油为主要原料,采用超高压均质(UHPH)方法制备牡丹籽油纳米乳液并研究UHPH压力、牡丹籽油用量、Tween-80用量对纳米乳平均粒径的影响。通过响应面法优化了制备条件并对牡丹籽油纳米乳液的稳定性进行初步评价。结果表明:最佳工艺参数为UHPH压力164 MPa、牡丹籽油用量为总乳液质量的7.8%、Tween 80用量为总乳液质量的3.7%,最小粒径为(111.8±1.43) nm。贮藏温度、贮藏时间对牡丹籽纳米乳液平均粒径及Zeta电位的影响显著。UHPH制备的牡丹籽油纳米乳液贮藏稳定性较好。Using peony seed oil as the main raw material,the peony seed oil nanoemulsion was prepared by the ultra high pressure homogenization( UHPH) method and the effects of UHPH pressure,peony seed oil dosage and Tween-80 dosage on the average particle size of nanoemulsion were studied. The preparation conditions were optimized by response surface methodology,and the stability of the peony seed oil nanoemulsion was preliminarily evaluated. The results showed that the optimal process parameters were UHPH pressure 164 MPa,peony seed oil dosage for the total amount of emulsion mass was7. 8 %,Tween 80 dosage for the total amount of emulsion mass was 3. 7 %,and the value of the minimum particle size was( 111. 8 ± 1. 43) nm. The storage temperature and storage time have significant effects on the average particle size and Zeta potential of the peony seed nanoemulsion. The peony seed oil nanoemulsion prepared by UHPH has better storage stability.
