See what biological functions EGCG has

1.

The super antioxidant effect of EGCG: catechins have been noted as a natural antioxidant and free radical scavenger, with a high scavenging effect on reactive oxygen species and free radicals, and a high inhibitory effect on lipid peroxidation, which is uncommon among the identified antioxidants.

2. 

Antitumour effects of EGCG: Studies have shown that EGCG and green tea extracts can prevent carcinogenesis in various organs of rodents. Animal studies found that EGCG treatment reduced tumour weight in mice, but had no significant effect on body weight, heart weight, angiogenesis or the expression of vascular endothelial growth factor in heart and skeletal muscle. In addition, EGCG alone or in combination with oxaliplatin enhanced the efficacy of anti-rectal and prostate cancer drugs.

3.

The anti-obesity effect of EGCG: research shows that green tea consumption is negatively correlated with body fat content and waist circumference. eGCG is the main active ingredient of green tea, which can regulate lipid metabolism by increasing lipid excretion, reducing fat absorption, inhibiting lipid synthase activity to reduce fat synthesis, promoting cholesterol reversal and its excretion from the intestine, activating sympathetic nerve activity to promote fat oxidation and decomposition, etc. Reducing body mass. Simple obesity is mainly due to the body's intake of energy is greater than consumption, energy in the form of fat accumulation in the body, this kind of adipose tissue is white adipose tissue.

Application of EGCG in food

EGCG is a new resource food ingredient in China and is allowed to be added to any general food except infant food, but the daily intake is ≤300mg/day. EGCG is an excellent water-soluble antioxidant and is widely used in processed aquatic products, with the most obvious feature of keeping the meat colour of processed aquatic products unchanged and having a fresh appearance. Tea EGCG has the health care function of preventing cardiovascular disease, cancer prevention and anti-cancer, anti-aging, anti-radiation and so on. In 2003, a brand in Japan developed a lipid-lowering and weight-loss tea drink with catechin as the main raw material, which was the first to obtain a functional food approval from the Japanese Ministry of Health and Welfare and was a success in the Japanese market.
