| 吐温是一种水溶性表面活性剂，对蛋白乳状液的稳定性有显著影响。将吐温用于水剂法提取芝麻油和芝麻蛋白的研究，期望提高产品提取率。研究发现吐温类表面活性剂对芝麻油提取率都有显著影响，但对芝麻蛋白提取率影响不显著。利用正交实验优化吐温20辅助水剂法提取条件，得到最佳工艺条件为：pH 11，料液比1∶?6，浸提时间30 min，浸提温度50?℃，吐温20添加量1%。在最佳工艺条件下芝麻油提取率为（60.97±2.43）%，显著高于单纯水剂法的提取率（45.90±212）%，芝麻蛋白提取率为（63.53±1.79）%。 |
| 英文摘要: |
| Tween was a kind of water-soluble surfactant, and it has a significant influence on the stability of protein emulsion. Therefore, Tween was used in simultaneous aqueous extraction of sesame oil and sesame protein in order to improve extraction rates of the products. The results showed that Tween had significant influence on the extraction rate of sesame oil, but it had no significant influence on extraction rate of sesame protein. The orthogonal experiment was designed to optimize the Tween 20-assisted aqueous extraction conditions and the optimal conditions were obtained as follows: pH 11, solid-liquid ratio 1∶?6, extraction time 30 min, extraction temperature 50?℃ and dosage of Tween 20 1%. Under these conditions, the extraction rate of sesame oil was (60.97±2.43)%, which was much higher than that by aqueous extraction ((45.90±2.12)%), and the extraction rate of sesame protein was (63.53±1.79)%. |
