Publication number: 20100222439Abstract: This invention relates to a polymeric polyphenol containing beverage, In particular it relates to a substantially clear ambient temperature beverage comprising tea solids derived from fermented tea. The invention also relates to a method for improving the clarity of a polymeric polyphenol containing liquid composition. It has long been observed that on cooling an aqueous black tea infusion from about 90 degrees Celsius to ambient temperature, a marked increase in the turbidity of the infusion can be seen leading ultimately to precipitation of up to about 30% w/w of the total tea solids. This precipitate is known as tea cream. It is thought that this precipitate originates from initial self-associations of polymeric polyphenols and association with caffeine thereby forming nano-clusters. These nano-clusters are not themselves responsible for any turbidity or precipitation of tea solids.Type: ApplicationFiled: February 24, 2010Publication date: September 2, 2010Applicant: CONOPCO, INC., D/B/A UNILEVERInventors: Haitao Chen, Weichang Liu, Dabin Xie
