Abstract: Tea polyphenols, the main active component in tea, is a natural non-toxic and non-side-effect antioxidant, which is widely used in food, medicine, daily chemical, environmental protection, animal husbandry and other industries, to meet the consumer’s pursuit of natural green products. In this paper, the traditional extraction technology and new extraction technology of tea polyphenols were briefly analyzed and compared, providing some reference for the future innovation of tea polyphenols extraction technology.

Keywords: tea polyphenol; application; extraction process

茶多酚是從茶葉中提取的多酚類物質(zhì)的總稱,約占茶葉干重的15%~30%[1],因其氧化聚合而呈現(xiàn)淡黃至茶褐色,味微澀略帶茶香,易溶于乙醇、甲醇、乙酸乙酯、丙酮和熱水,不溶于苯及氯仿等有機溶劑,在pH值為2~7條件下穩(wěn)定,強酸、強堿、高溫、光照等條件下易氧化變質(zhì)。(剩余4764字)
