| 摘 要： | 为提高海蜇头糖蛋白提取效果,采用超声辅助提取工艺,在单因素试验的基础上,采用超声处理时间、超声功率和提取时间三因素三水平响应面分析试验以优化此工艺条件.结果表明:海蜇头目标糖蛋白超声辅助提取的最佳工艺条件为超声处理时间15 min,超声功率300 W,提取时间60 min;在此工艺条件下,糖蛋白实际得率为9.14%,与模型预测值之间具有较好的拟合性.在3个因素中,超声处理时间,超声功率对糖蛋白得率的影响极显著,提取时间影响不显著,且相互之间无交互效应.

| Abstract: | In order to optimize ultrasound-assisted extraction technology for the extraction of glycoprotein extraction from jellyfish (Rhopilema esculentum) oral-arms, on the basis of single factor experiments, the effects of operating conditions, such as ultrasonic time, ultrasonic power and extraction time on the yield of glycoprotein were analyzed by response surface methodology. The optimized conditions of ultrasound-assisted extraction were as follows: ultrasonic treatment time was 15min, ultrasonic power was 300W, and extraction time was 60min. Under the above-mentioned conditions, the actual yield of target glycoprotein was 9.14%, which is well matched with the predicted yield. Among three factors, ultrasonic treatment time and ultrasonic power had significant effects on the yield of glycoprotein, while extraction time had no remarkable effect. Moreover, there are no interaction among three factors. |
