摘要
[目的]从紫苏饼粕中提取多糖,可以提高紫苏籽饼粕的综合利用率。[方法]采用热水提取紫苏饼粕多糖,从液固比、提取温度、提取时间3个方面对得率进行考察。[结果]水提紫苏饼粕多糖的最佳提取条件为液固比35∶1,浸提时间4h,浸提温度80℃。在此条件下,多糖得率为8.34%。[结论]该优化工艺对紫苏饼粕中多糖的进一步研究具有一定的参考价值。
[Objective] The research aimed extract polysaccharide from perilla seed meal to improve the comprehensive utilization rate of the perilla meal.[Method] Hot water was employed as extracting agent.Three factors,including ratio of liquid-solid,temperature,and time were investigated.[Result] Optimum conditions for extraction was as follows：the ratio of liquid-solid was 35∶1,temperature was 4h,and time for extraction was 80 ℃.Under the optimum conditions,the extraction ability of polysaccharides in perilla was 8.34%.[Conclusion] The optimized technology could provide reference for the further study of polysaccharides from perilla meal.
