Conclusion：Conform
to Green Tea Extract Standard
|
Function of Green tea extract
Green tea extract, like many herbs, is standardized in the
production phase to guarantee that a certain percentage of the active
ingredients remain present in the final capsulized form. The active ingredients
in green tea extract are polyphenols in the form of flavonoids like catechins and epigallocatechin gallate (EGCG). Polyphenols, flavonoids, catechins
and EGCG are powerful antioxidants that appear to interfere with and reduce the
spread of certain types of cancer cells. The antioxidant activity of EGCG in green tea extract powder is purportedly up to 100 times more powerful than that of
vitamin C or E.
(1)Application
of tea polyphenols in the industry of medicine
Tea
polyphenols can protect easy-oxidant in the body from oxidizing through
oxidized itself to made cellular activity normalize.
(2)Application of tea polyphenols in food industry
The fat in food is easy to oxidize itself to produce free radicals. Tea
polyphenols can supply lots of protons, which combine with over 98% of these
free radicals, thereby stop next chemical reaction and protect the fat from
further oxidizing.
(3)Application of tea polyphenols in the industry of daily chemicals
In general, most cosmetics contain oil, wax, hydrocarbon and surface active
agent, all that easily react to oxygen in air and produce peroxidant, acids,
aldehydes etc.
