膜过滤技术在茶叶深加工中的应用研究进展 1,2 2 1 邹锋扬 ,金心怡 ,郁 军 (1. 大闽食品（漳州）有限公司博士后工作站，福建漳州 363000； 2.福建农林大学茶叶研究所,福州 350011) 摘要：综述了微滤技术、超滤技术和纳滤技术在茶叶深加工中的应用研究进展，指出机械过滤、高速离心及化学 法处理等传统分离提取方法的澄清效果欠佳，目标产品质量较低，而膜过滤技术不改变目标产品的色、香、味。 研究结果表明，膜孔径、压力、温度等因素对茶提取液的水浸出物、茶多酚、氨基酸、咖啡碱、可溶性糖、儿茶 素等生化成分以及澄清度、色度和感官品质产生不同影响，并阐述了膜清洗和膜再生的方法，为研究膜过滤技术 以及膜的清洗和再生提供参考。 关键词：茶学；茶叶深加工；微滤；超滤；纳滤；膜清洗1 Research and Application Progress of Membrane Filtration Technology in the Deep-processing of Tea 1,2 2 1 ZOU Fengyang , JIN Xinyi , YU Jun (1. Postdoctoral Working Station, Damin Food (Zhangzhou) Co. Ltd, Zhangzhou 363000，Fujian, China; 2. Agriculture and forestry university in Fujian tea research institute, Fuzhou 350011, China.) Abstract:The author reviewed the application of MF,UF and UF in tea further processing. the tradition extraction method mainly adopt the mechanic filter，high-speed centrifuge，chemical treatment. The clearance of finished product is not very good and with lower quality. The membrane filtration technology could remain the original colour, flavor and taste. the results indicate the membrane aperture, pressure, temperature has impact on the water extract, teapolyphenol, amino acid, caffeinne, soluble water, catechin content and the clearance and colour of finished product and means of regeneration and cleaning of membrane. It is expatiated on. It provide reference information for the research on membrane filtration technology and regeneration and cleaning of membrane. Keywords: tea science, deep-processing of tea ，MF，UF ，NF ，membrane cleaning 随着生活水平的不断提高，人们日益追求绿色、天然、健康的饮料。茶叶被揭示出对人体具有保健效
