| 中文摘要: |
| 旨在为脂溶性生物活性物质的包埋递送提供参考，以大豆分离蛋白（SPI）-葡聚糖共轭物（SDC）为乳化剂和稳定剂，采用两步法运用高压微射流制备Pickering乳液（SDC-PEs)，通过单因素实验研究了均质压力、均质次数、SDC添加量对乳液粒径和多分散指数（PDI）的影响，并采用响应面实验对SDC-PEs的制备条件进行了优化。另外，对最佳工艺条件下制备的SDC-PEs性质进行了分析。结果表明：SDC-PEs的最佳制备工艺条件为均质压力140 MPa 、均质次数6次、SDC添加量2.13%、油相体积分数10%，在此条件下SDC-PEs的平均粒径为210.33 nm，PDI小于0.20；SDC-PEs表现出良好的pH稳定性、抗离子强度稳定性、温度稳定性和储存稳定性，且优于以SPI稳定的Pickering乳液（SPI-PEs）。综上，通过添加SDC可以制备出稳定性良好的Pickering乳液。 |

| To provide a reference for the encapsulation and delivery of lipophilic bioactive substances, Pickering emulsions （SDC-PEs)was prepared by using a two-step method of high-pressure microfluidization process with soybean protein isolate(SPI)-dextran conjugate(SDC) as emulsifier and stabilizer. Single-factor experiments were conducted to investigate the effects of homogenization pressure, homogenization times, and SDC dosage on emulsion particle size and polydispersity index (PDI). The preparation conditions of SDC-PEs were further optimized using response surface methodology. Additionally, the properties of SDC-PEs prepared under the optimal conditions were analyzed. The results showed that the optimal preparation parameters of SDC-PEs were as follows: homogenization pressure 140 MPa, homogenization times 6, SDC dosage 2.13%, and volume fraction of oil phase 10%. Under these conditions, SDC-PEs exhibited an average particle size of 210.33 nm with a PDI below 020. The SDC-PEs showed excellent stability against pH, ionic strength, temperature, and storage, outperforming SPI-stabilized Pickering emulsions (SPI-PEs). In conclusion, Pickering emulsions with good stability can be prepared by adding SDC. |
