Tea polyphenols, especially catechins such as epigallocatechin gallate (EGCG), are bioactive compounds known for their antioxidant properties. With more than 8,000 studies included in the PubMed database, these molecules show remarkable versatility in the fields of health, food technology, and personal care.
Three core functions
1. Guardian of cardiovascular health
Principle of action: Improves blood flow by stimulating the release of nitric oxide from the vascular endothelium (Journal of the American College of Cardiology, 2022) [1]
Human data: 150 patients with hyperlipidemia took 500 mg of tea polyphenols daily for 3 months. After:
Low-density lipoprotein decreased by 14.2%
Triglycerides decreased by 11.5% (Clinical Nutrition, 2023) [2]
2. Pioneer in anti-cancer and antioxidant effects
Free radical scavenging ability: In an oily environment, the efficiency of neutralizing reactive oxygen is 4 times that of vitamin C [3]
Breast cancer inhibition: The laboratory has confirmed that 50 μM concentration of EGCG can block the activity of cancer cell DNA replication enzymes and reduce tumor growth by 67% (Molecular Cancer Therapy, 2023) [4]
3. Liver detoxification expert
Heavy metal shielding: Combines with lead and cadmium to form precipitates, reducing intestinal absorption by 52% (Environmental Science and Technology, 2022) [5]
Alcoholic liver protection: A dose of 300 mg/kg reduced the liver damage indicator ALT in alcohol-exposed rats by 38% (Journal of Hepatology, 2021) [6]
Natural solutions for the food industry
| Application areas | Functional characteristics | National standard limit |
| Edible oil | Delay oxidative rancidity | ≤0.4g/kg |
| Processed meat products | Inhibit the formation of nitrosamines | ≤0.2g/kg |
| Baked food | Maintain starch structure stability | ≤0.3g/kg |
Effect:
The shelf life of sausages is extended by 21 days under refrigerated conditions at 4°C (Food Control, 2023) [7]
The amount of acrylamide generated in fried foods is reduced by 44% (Agricultural Food Chemistry, 2022) [8]
Biotechnology breakthroughs in the beauty industry
Skin care:
Acne management: After using 2% EGCG gel for 8 weeks, inflammatory acne was reduced by 58% (Journal of Cosmetic Dermatology 2023) [9]
Whitening and lightening: Inhibits the activity of key enzymes in melanin synthesis by 73%, which is better than kojic acid (Pigment Cell Research 2022) [10]
Oral health: Continuous use of 1% tea polyphenols mouthwash for 6 weeks reduced dental plaque by 34% (Journal of Periodontology 2023) [11]
Enhancement plan:
Food application: Select ethanol-based formula to enhance the efficacy of fat-soluble ingredients
Skin care products: Use stabilized derivatives such as EGCG palmitate
