【摘要】 本试验研究了超声波辅助提取玫瑰花多糖及口服液制备的最佳工艺条件。以玫瑰花多糖得率和感官评分为指标,采用单因素试验和正交试验,确定最佳工艺参数。结果表明,超声波辅助提取玫瑰花多糖的最佳工艺参数为:料液比1∶30(g·m L^-1),超声时间30 min,超声温度70℃,超声波功率500 W,在此条件下,玫瑰花多糖得率为2.11%。玫瑰花多糖口服液最佳工艺参数为:玫瑰花多糖添加量30%,黄原胶添加量0.06%,柠檬酸添加量0.06%,白砂糖添加量10%。该条件下,玫瑰花多糖口服液感官评分为89分。更多还原

【Abstract】 The optimum technological conditions of ultrasonic assisted extraction of rose polysaccharide and preparation of oral liquid were studied. The optimum technological parameters were determined by single factor test and orthogonal test. The results showed that the optimum technological parameters of ultrasonic assisted extraction of rose polysaccharide were as follows: solid-liquid ratio 1∶ 30(g·mL^-1), ultrasonic time 30 min, ultrasonic temperature 70℃,ultrasonic power 500 W. Under these conditions, the yield of rose polysaccharide was 2.11%. The optimum technological parameters of rose polysaccharide oral liquid were as follows: rose polysaccharide addition 30%, xanthan gum addition 0.06%, citric acid addition 0.06%and white granulated sugar addition 10%. Under this condition, the sensory score of rose polysaccharide oral liquid was 89.更多还原
