超声波辅助提取金耳多糖的工艺优化

摘要

This article took dried tremella as the raw material, using ultrasonic assisted extraction, optimization of its extraction process. Single factor test and orthogonal study showed the best extraction conditions. The results showed that:the extraction temperature and ultrasonic power were the key factors;the best extraction condi-tions were 80 mL/g, solid to liquid;30 min,ultrasonic time;400 W, ultrasonic power;30 min, extraction time;70℃, temperature. By such conditions, extraction yield of tremella polysaccharide was significantly improved to 17.36%.%以干燥金耳为原料，采用超声波辅助提取金耳多糖，优化其提取工艺。通过单因素试验和正交试验得到最佳提取工艺。其结果表面：影响金耳多糖提取率的主要因素是超声浸提温度与超声波浸提功率；金耳多糖的最佳提取工艺为料液比为80 mL/g，超声波处理时间为30 min，超声波处理功率为400 W，浸提时间为30 min，浸提温度为70℃。采用此工艺，金耳多糖的得率为17.36%，其得率明显提高。
