Grade Green Tea Extract

Grade Green Tea Extract

  1. Product Overview
    English Name: Grade Green Tea Extract
    Botanical Source: Extracted from the leaves of Camellia sinensis, the tea plant. Green tea extract is derived from unfermented tea leaves, preserving its high content of bioactive compounds like polyphenols and catechins.
  2. Specification
    Purity: Total Polyphenols ≥ 95% (HPLC-tested), with Epigallocatechin Gallate (EGCG) often ≥ 50% (HPLC-tested). The extraction process involves solvent extraction (typically with water or ethanol) followed by purification via chromatography to isolate and concentrate active compounds. Stringent quality control ensures low levels of heavy metals, pesticides, and microbial contaminants, meeting international standards for pharmaceutical, cosmetic, and food applications.
  3. Appearance
    It appears as a fine, light green to dark green powder with a faint, characteristic tea – like aroma. The powder is free – flowing, facilitating easy integration into various formulations.
  4. CAS Number
    Key component Epigallocatechin Gallate (EGCG): CAS NO.: 989 – 51 – 5. While green tea extract is a complex mixture, this CAS number is critical for identifying its primary bioactive compound in research and regulatory contexts.
  5. Lead Time
    Lead time: 3 – 7 Working Days. Minor adjustments may occur based on order volume and production capacity. Our advanced extraction facilities and streamlined logistics ensure timely delivery, though seasonal tea leaf availability may slightly impact lead times.
  6. Package
    Packaging: Standard packaging is 25kg food – grade drums, with 27 drums per tray for efficient transportation. Drums are designed to protect the powder from moisture, light, and physical damage. Custom packaging, such as smaller sachets for retail or bulk containers for industrial use, is available upon request.
  7. Main Market
    Main Market: European, North America, Asia etc. In Asia, particularly in China and Japan, green tea has millennia of traditional use. In Europe and North America, the extract is popular in health, wellness, and cosmetic industries due to its proven bioactivity and natural origins.
  8. Applications
    • Health Supplements:
      • Antioxidant Powerhouse: Rich in catechins like EGCG, green tea extract scavenges free radicals, protecting cells from oxidative damage. This supports heart health, immune function, and may reduce the risk of chronic diseases such as cancer and neurodegenerative disorders.
      • Metabolism Boost: Studies link green tea polyphenols to enhanced fat oxidation and thermogenesis, making it a popular ingredient in weight – management supplements.
      • Anti – inflammatory: It inhibits pro – inflammatory cytokines, offering relief for conditions like arthritis and promoting gut health.
    • Cosmetics:
      • Skin Protection: In creams, serums, and masks, green tea extract protects against UV damage and environmental stressors. Its antioxidant properties reduce premature aging, minimizing fine lines and age spots.
      • Oil Control: Catechins help regulate sebum production, making it ideal for oily or acne – prone skin. It also soothes inflammation, reducing redness and blemish severity.
      • Hair Care: Added to shampoos and conditioners, it nourishes hair follicles, improves scalp health, and may prevent hair loss by combating oxidative stress.
    • Food Industry:
      • Natural Antioxidant: Used as a preservative in snacks, beverages, and dairy products to extend shelf life by inhibiting lipid oxidation.
      • Functional Foods: Fortifies health drinks, energy bars, and dietary supplements with its nutrient density. Its mild bitter taste enhances the flavor profile of teas, confectionery, and baked goods.
      • Beverages: A key ingredient in ready – to – drink green tea beverages, providing both flavor and health benefits without synthetic additives.
