| 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°C, extraction time 1.5。 (2) The excipient is mannitolof 22%,the best conditions of given the shape ... |
