Recovery of Tea-Polyphenol from Low-Grade Tea
A Powerful All Natural Anti-Oxidant

Introduction

Tea-polyphenol (TP) is a mixture of a group of polyphenolic compounds which occur naturally in tea. Normally, dry tea flush contains more than 10% of tea-polyphenol.Tea-polyphenol's AI (Anti-oxidation index) value is as high as 10~20 times that of mixed vitamin E. It can also be used in medicines to fight cancer, aging, human body free radical eliminators, hyperlipemic agents, and microbial infestations.

Our Technology

Our scientists have developed a technique which can recover teapolyphenol from low-grade tea with good yield and high quality. Compared with the other methods reported or applied, this extracting method is much better in many respects including:

A relatively low fundamental investment

Short processing time

High TP recovery

(>8%, relative to dry tea)

Low extracting reagent consumption

stable production quality

Our technology also results in a high TP percentage (>95%, determined by using the analysis method of the International Commerce and Trade).

Results

Our TP product yields the following analysis:

TP Percentage: 98.6% *

Water: 2.37%

Ashes: 0.32%

lead: <1.0 mg/kg

copper: <10.0 mg/kg

arsenic: <0.5 mg/kg

Tea-polyphenol's AI (Anti-oxidation index) value is as high as 10~20 times that of mixed vitamin E
