Tea polyphenol（CAS:84650-60-2)

Green Tea Extract (Tea Polyphenol, CAS: 84650-60-2) is a natural water-soluble plant extract refined from fresh green tea leaves through modern low-temperature extraction and multi-stage purification technology. The core active substances are tea polyphenols and catechins, among which EGCG is the most functional monomer, endowing the product with powerful antioxidant and anti-corrosion capabilities. Compared with raw green tea leaves, the purified green tea extract removes invalid impurities such as crude fiber and sugar, highly concentrates active ingredients, and has far stronger antioxidant activity. With excellent water solubility, natural safety and cost-effectiveness, it has become a versatile mainstream raw material widely used in food processing, cosmetics, health supplements, biomedicine and daily chemical industries.

In terms of physical and chemical properties, green tea extract appears as light yellow to brownish-yellow fine powder with fresh green tea fragrance. It features excellent water solubility, which can be quickly dissolved in cold and warm water, and is also compatible with ethanol solvents. The product maintains stable properties under sealed and normal temperature storage. However, polyphenols and catechins are sensitive to high temperature, strong light and humid environment. Long-term improper storage will cause oxidative browning, moisture agglomeration and activity attenuation. It must be stored in sealed, light-proof, cool and dry conditions to prevent oxidation, ensuring stable quality and meeting food-grade, cosmetic-grade and research-grade raw material specifications.

In industrial production, high-quality fresh green tea leaves are selected as raw materials. The complete production process includes raw material screening, low-temperature drying, ultrafine crushing, constant temperature water extraction, vacuum concentration, impurity filtration, macroporous resin enrichment, decolorization, sterilization and vacuum drying. Adopting pure physical low-temperature extraction technology without chemical additives and harmful residues, the process effectively protects the active structure of tea polyphenols and EGCG, and removes redundant impurities. We can provide customized products with different polyphenol contents. The finished powder has uniform texture, good solubility and stable activity, suitable for mass production, high-end formula customization and pharmacological research.

Green tea extract has diverse and powerful biological activities, mainly including anti-oxidation, free radical scavenging, anti-inflammation, bacteriostasis and natural anti-corrosion. Its core ingredient EGCG can efficiently eliminate excess free radicals, inhibit lipid peroxidation and delay aging, with better antioxidant effect than vitamin C and vitamin E. It can significantly inhibit the release of inflammatory factors and resist harmful bacteria to relieve skin sensitivity. In addition, it prevents grease rancidity to extend the shelf life of food and regulates human lipid metabolism to maintain physical health, which makes it an ideal natural substitute for chemical additives.

This product covers multiple high-end application scenarios. In the food industry, it serves as a natural antioxidant and preservative for grain, oil, beverages and baked goods. In the cosmetic industry, it is widely added in anti-aging and soothing skincare products. In the health product industry, it is applied to anti-aging and metabolic conditioning dietary supplements. In scientific research, it is used as a standard reference substance for polyphenol pharmacological experiments and component analysis.

With the popularization of green and healthy consumption concepts, natural plant-based raw materials have gradually replaced chemical additives. The market demand for green tea extract keeps increasing year by year. With the continuous optimization of purification technology and mature industrial production system, the product performance will be further improved. Relying on comprehensive efficacy and high cost performance, green tea extract will maintain strong market competitiveness in multiple industries and have broad development prospects in the global market.
