摘    要:采用冷冻干燥法制备茶多酚前体脂质体,并对其稳定性进行研究。通过考察冷冻保护剂的种类、冷冻保护剂的用量、预冻时间、冷冻干燥时间等因素对茶多酚前体脂质体复水后包封率的影响。在最佳制备工艺条件下:海藻糖为冷冻保护剂,海藻糖与卵磷脂的质量比为4∶1,预冻时间为6h,冷冻干燥时间为36h,制备得到的茶多酚前体脂质体复水后包封率45.5%,稳定性高。该法制备的茶多酚前体脂质体包封率高,稳定性好,可以长时间贮藏。

关 键 词:茶多酚前体脂质体  冷冻干燥  冷冻保护剂  稳定性

Abstract:The tea polyphenols precursor liposomes was prepared through the use of freeze-drying to improve the stability of the tea polyphenol liposome suspension; Investigated the effects of cryoprotectant types,cryoprotectant amount,pre-freezing time and the freeze-drying time and other factors on the encapsulation efficiency of the polyphenols Proliposome after rehydration was investigated; the best freeze-drying conditions is as follows: the cryoprotectant is trehalose,protection and Lecithin mass ratio is 4∶ 1,pre-freeze time of the tea polyphenol liposomes is 6 hours,freeze-dried for 36 hours. The encapsulation efficiency of the tea polyphenols Proliposome after rehydration was 45. 5% and its stability is high. The tea polyphenols Proliposome's production is highly encapsulated with good stability and storage.
Keywords:tea polyphenols proliposome  freeze drying  cryoprotectants  stability
