[What is green tea extract]

Green tea is the second largest beverage demanded by consumers worldwide. Used in China and India for its medicinal effects. There are several compounds extracted from green tea including catechins which contain an enormous amount of hydroxyphenols that are easily oxidized, congregated and contracted, which explains its good anti-oxidation effect. Its anti-oxidation effect is 25-100 times as strong as those of vitamin C and E.

It is widely used in medicines, agriculture, and chemical and food industries. This extract prevents cardio-vascular disease, lowers the risk of cancer, and decreases blood sugar and blood pressure, as well as viruses. In the food industry, the anti-oxidation agent used for preserving food and cooking oils.

[Function]

1. Green tea extract can reduce blood pressure, blood sugar, blood lipids.

2.Applied in food field, Green tea extract is used as natural antioxidant, antistaling agent, and anti-fading agents.

3.Applied in pharmaceutical field, Green tea extract is used to prevent and cure cardiovascular disease, diabetes.
