| 目的 研发出一款新型的花椒精油Pickering乳液，为花椒精油Pickering乳液的制备和花椒精油应用场景的拓宽提供参考。方法 以花椒精油为油相，玉米醇溶蛋白-柑橘果胶复合纳米粒子为固体颗粒，制备花椒精油Pickering乳液。研究复合纳米粒子质量浓度(20、25、30、35、40 g/L)对Pickering乳液粒径、电位、微观结构、稳定性、流变特性等理化性能和抗氧化性能、抑菌性能等功能活性的影响。结果 随着复合纳米粒子浓度的提高，乳液的粒径呈先降后增趋势，ζ-电位绝对值、包埋率则呈先增后降趋势，当质量浓度为35 g/L的时候，乳液粒径最小为1 900.3 nm、ζ-电位和包埋率最大分别为32.7 mV、95%;此浓度下乳液贮藏稳定性最好，且具有优异的温度稳定性，在酸性(pH=2、3、4)和碱性环境(pH=8、9)下稳定性表现良好;所有乳液均显现出明显的剪切变稀行为，属于假塑性流体;在低频下乳液损耗模量大于储能模量，呈流体状态;相较于花椒精油，负载花椒精油的Pickering乳液的抗氧化性能和抑菌性能得到了显著提高。结论 复合纳米粒子质量浓度为35 g/L时制备的负载花椒精油Pickering乳液具有较好的稳定性、抗氧化和抑菌性能。 |

| The work aims to develop a new type of Pickering emulsion loaded with Zanthoxylum bungeanum essential oil, and provide a reference for the preparation of Zanthoxylum bungeanum essential oil Pickering emulsion and the expansion of the application scenarios of Zanthoxylum bungeanum essential oil. The Pickering emulsion loaded with Zanthoxylum bungeanum essential oil was prepared with Zanthoxylum bungeanum essential oil as oil phase and zein-citrus pectin composite nanoparticles as solid particles. The effects of the concentration of composite nanoparticles (20, 25, 30, 35, 40 g/L) on the physical and chemical properties (particle size, potential, microstructure, stability, rheological properties), as well as functional activities (antioxidant and antibacterial capacities) of Pickering emulsion were investigated. The results showed that with the increase of the concentration of composite nanoparticles, the particle size of the emulsion firstly reduced and then raised, the absolute value of ζ-potential and the embedding rate initially increased and then decreased. When the concentration of composite nanoparticles was 35 g/L, the minimum particle size of the emulsion was 1 900.3 nm, the maximum ζ-potential and entrapment rate were 32.7 mV and 95%, respectively. At this concentration, the storage stability of the emulsion was the best. The emulsion had excellent temperature stability, good stability in acidic (pH=2, 3, 4) and alkaline (pH=8, 9) environments. All emulsion presented obvious shear thinning behavior and belonged to pseudoplastic fluid; At low frequency, the loss modulus of the emulsion was greater than the storage modulus, showing a fluid state. Compared with Zanthoxylum bungeanum essential oil, the antioxidant and antibacterial properties of Zein-Citrus pectin Pickering emulsion loaded with Zanthoxylum bungeanum essential oil were significantly improved. In conclusion, when the concentration of composite nanoparticles is 35 g/L, Zein-Citrus pectin Pickering emulsion loaded with Zanthoxylum bungeanum essential oil possess good stability, antioxidant and antibacterial properties. |
