TEA POLYPHENOLS ( Tea Polyphenols ) is a kind of natural extracted from tea polyphenols , the main ingredients for catechins ( Catechin , belongs to the flavanols ) , accounts for about 60%-80% of total polyphenols . The catechins are mainly composed of EGCG , ECG , EGC , EC , D , L-C and several monomer composition . Catechins containing polyphenol hydroxyl , so it has strong antioxidant activity and free radical scavenging ability .
Stability : stable in PH4-8 , alkali , acid , light , heat perishable .
Safety evaluation: non-toxic .
Sensory indicators: 1 appearance: light yellow or pale yellow green is often powdered solid . 2 properties: the product is soluble in water or aqueous ethanol , taste bitter .
Storage : store in a cool , dark , dry place , shelf-life of two years .

Application
Tea polyphenols in human health aspects of the application
● antioxidant , antitumor , resistance to radiation : tea polyphenol can inhibit damage cellular free radical generation and activation of free-radical protection system, but also a direct free radical scavenging , protection DNA . Show the anti aging , anti mutation and radiation injury effect . Therefore , tea polyphenols can be applied in anti aging health products health care products , enhancing immunity , anti-tumor drugs for adjuvant treatment etc. .
● hypolipidemic , promote fibrinolysis : tea polyphenols have anticoagulant , facilitates fibrinogen lysis , inhibition of low density lipoprotein cholesterol and glycerin three greases role . Therefore , tea polyphenols can be applied to the treatment of high blood cholesterol , high cholesterol , hypertension and cerebral thrombosis, coronary heart disease , the transition of obesity adjuvant drugs .
● bacteriostasis , deodorization effect : tea polyphenols inhibit some bacteria , fungi , with virus and the role of Mycoplasma and odor removal function . Therefore , tea polyphenols can be applied to tablets , oral , topical and other antibacterial drugs , prevention and treatment of oral diseases , intestinal diseases , skin diseases , such as influenza . Tea polyphenols is also used in toothpaste , chewing gum and other aspects to prevent dental caries , deodorizing effect .
The tea polyphenol and its application in cosmetics : Tea Polyphenols with antioxidant , radiation resistance , antibacterial effects , therefore , used in cosmetics or skin care products can not only prevent the oxidation of oily ingredients in cosmetics , skin whitening , can also have reduced pigmentation , solar ultraviolet radiation preventing function .
Tea polyphenols in oily food applications
Tea polyphenols by phenolic hydroxyl group has provided H+ proton ability , can capture grease auto oxidation and the formation of free radicals , oxidative polymerization of catechin oxidation polymer free radical chain reaction , suspension , thereby inhibiting the oily food fat auto-oxidation , is a synthetic antioxidant bht , BHA , TBHQ ideal natural substitute . Therefore , tea polyphenols can be applied in edible animal and plant oils , ALA and Sterilization packaging meat , fried food and other oily food antioxidant preservation . At the same time , tea polyphenols with other antioxidants are not used for anticorrosion and bactericidal function , frozen aquatic products can be both a bacteriostatic preservative and antioxidant functions .
The application of tea polyphenols in feed
Tea polyphenols applied to livestock , poultry feed can be used as feed antioxidant , at the same time , can improve the immunity of calves , young , its antibacterial action can improve the intestinal microbial balance , improve resistance to disease . Livestock , poultry food polyphenols , can reduce the fat content in meat , eggs and cholesterol content , improve the meat quality and taste .
