| 摘 要： | 本文探讨了以粗蜂胶为原料，研制蜂胶冻干粉的的工艺。结果表明：蜂胶冻干粉的工艺流程为粗蜂胶—→醇溶法提取—→赋形—→冻干—→冻干粉。最佳工艺条件为：（1）醇溶法提取蜂胶的最佳条件：固液比：1：25，乙醇溶液浓度75％，提取温度80℃，提取时间1．5h。（2）赋形剂为22％甘露醇，赋形的最佳条件为：22％甘露醇与4％的蜂胶乙醇溶液按76：24的比例混合。（3）冻干条件：预冻温度-74℃，预冻时间2小时，抽真空时间24小时，升温干燥20℃，升温干燥30分钟，冷阱温度为-52℃。在此条件下生产的蜂胶冻干粉的溶解度为87％，水分含量为0．93，总黄酮含量为0．49％。

| Abstract: | This paper deals with the preparation of lyophilized propolis powder which uses the crude propolis as raw materials. The results showed ： the process of lyophilized propolis powder is crude propolis → ethanol extraction → shaped → lyophilized → lyophilized powder. Optimum conditions ： （1） the best conditions of ethanol Extraction Propolis ： the ratio ： 1：25 ,ethanol concentration： 75% ,extraction temperature： 80℃, extraction time 1.5. （2） The excipient is mannitolof 22%, the best conditions of given the shape ： using 22% manrtitol propolis which is mixed by 24：76 ratio （3） Freeze-drying conditions ： after two hours -74~C freezing puts them in the vacuum for 24 hours and warm and dry at 20℃ for 30 minutes. The cooling temperature is -52℃. Under this condition, the solubility of lyophilized propolis powder is 87% and moisture content of 0.93%, Flavonoids content is 0.49%. |
