Study on New Technology For Producing Decaffeined Tea-Polyphenols Using Ion Precipitation and Flocculation Methad

Abstract

Abstract: This paper studied a new technology for producing decaffeined tea polyphenols(TP) from sresh tea leaves.Process of ion precipitation to separate TP in the medium of mixed solvent composed of water and alcohol and process of floculation to remove caffeine from the precipitation tracsfomation solution were studied experimentally.The results showed that in this new technology,product of TP with low caffeine content and good production yield could be gained.Meanwhile it can avoid suing noxious organic solvent and raise the safety of production process.

Key words: , Tea polyphenols Caffeine Ion precipitation Flocculation；
