【摘要】 目的确定余甘子果汁的干燥工艺,并比较不同产地的余甘子中多糖含量。方法用正交试验法优选喷雾干燥的最佳工艺参数,用优选出的条件干燥4个余甘子高产省份的余甘子鲜果汁,用硫酸-苯酚法对余甘果汁干粉中多糖显色,用分光光度法测多糖含量。结果与结论余甘子果汁的喷雾干燥条件为进口温度160℃,出口温度80℃,喷雾压力150kPa。广州产余甘子果汁干粉中的多糖含量最高。更多还原

【Abstract】 Objective To determine the optimal spraydrying parameters of phyllanthus emblica L.juice and to compare the polysaccharide contents of phyllanthus emblica L.in different habitats.Methods To optimize the optimal technological parameters with orthogonal method. To dry phyllanthus emblica L.uice in four highyield habitats with the optimal conditions.To detect the polysaccharide content with phernolsulphate colorimetry.Results and Conclusion The spraydrying parameters of Phyllanthus emblica L.juice are the enter temperature is 160℃ and the exit temperature is 80℃ ,the pressure is 150 kpa.The polysaccharide content of phyllanthus emblica L. juice powder in habitat Guangzhou is the highest.更多还原
