Bulk Green Tea Extract Tea Polyphenols 50%-98% | CAS 90046-52-5

• Green Tea Extract is a standardized botanical essence refined from the tender leaves and leaves of Camellia sinensis via modern extraction and separation technologies. Its core active component is Tea Polyphenols, with Epigallocatechin Gallate (EGCG) as the most pivotal constituent. Boasting excellent antioxidant, anti-inflammatory and metabolism-regulating biological activities, it is a star natural raw material widely used in health food, functional beverages, skincare products and the field of natural preservation.

 

Q: What is Green Tea Extract, and what are its key active components?

A: Green Tea Extract is a standardized botanical extract refined from the tender leaves of Camellia sinensis via modern extraction and purification technologies. Its core active components are Tea Polyphenols, with Epigallocatechin Gallate (EGCG) as the most potent and representative monomer, accounting for the main antioxidant and biological activity of the extract. It also contains small amounts of natural tea polysaccharides and amino acids with synergistic effects.

Q: What is the core advantage of Green Tea Extract in antioxidant activity?

A: Its antioxidant capacity far exceeds that of Vitamin C and E—EGCG can effectively scavenge various free radicals (e.g., superoxide anion, hydroxyl radical) in the human body, protect cells from oxidative damage, and form a multi-layered antioxidant network that is more stable and durable than single antioxidants, making it a mainstream natural antioxidant raw material in the industry.

Q: What is the difference between Tea Polyphenols and EGCG in Green Tea Extract?

A: Tea Polyphenols are the total mixture of phenolic active components in green tea extract (including EGCG, EGC, ECG, etc.), while EGCG is the most active monomer in Tea Polyphenols, contributing about 50%-70% of the total antioxidant activity. Tea Polyphenols are cost-effective for general antioxidant products, while high-purity EGCG is suitable for high-end formulations with targeted efficacy requirements (e.g., cardiovascular health, anti-aging skincare).

Q: What standardized specifications of Green Tea Extract do you provide?

A: We offer a full range of food/health/pharmaceutical/cosmetic grade products with customizable core component content:

Tea Polyphenols: 50%, 70%, 98% (common specifications, customizable for other ranges);

EGCG: 40%, 60%, 95% and above (high-purity monomer, for high-end formulations);

All specifications support low-caffeine customization (caffeine ≤0.5% or ≤1.0%) for caffeine-sensitive product development.

Q: Can you provide water-soluble Green Tea Extract for beverage formulations?

A: Yes. Our standard Green Tea Extract has good water dispersibility, and we can customize highly water-soluble Green Tea Extract via special modification technology for clear functional beverages, oral liquids and solid beverages. The water-soluble extract has no precipitation, stable color and luster, and no obvious impact on the flavor of beverage products.

Q: Do you provide decaffeinated Green Tea Extract, and what is the decaffeination technology?

A: Yes. We adopt low-temperature molecular distillation and resin adsorption technology for decaffeination, which can reduce the caffeine content to ≤0.5% (even trace levels) while maximizing the retention of Tea Polyphenols and EGCG activity—avoiding the loss of active ingredients caused by traditional high-temperature decaffeination, and ensuring the efficacy and quality stability of the extract.

Q: What are the core application fields of Green Tea Extract, and which specifications are recommended for each field?

A: It is a multi-functional natural raw material widely used in four major fields, with targeted specification recommendations:

Dietary supplements/health food: 50%-70% Tea Polyphenols (cost-effective) for antioxidant/weight management; 98% Tea Polyphenols/40%-60% EGCG for cardiovascular/brain health support;

Functional foods/beverages: 50% Tea Polyphenols (water-soluble) for healthy drinks/yogurts/snacks, low-caffeine specification recommended for children’s and adult low-caffeine products;

Cosmetics/personal care: 70%-98% Tea Polyphenols/60%-95% EGCG for anti-aging/soothing/sun protection skincare, suitable for serums, creams, masks and toners;

Natural food preservation: 98% high-purity Tea Polyphenols for oils/fat-rich foods (e.g., nuts, meat products) as a natural antioxidant to replace synthetic preservatives.

Q: Is Green Tea Extract compatible with common raw materials, and what are the key formulation notes?

A: It has excellent compatibility with most raw materials, including vitamins (VC, VE), amino acids, plant extracts (ginseng, aloe), food additives and skincare base materials. Key formulation and processing notes:

Temperature: Stable at ≤80℃; add at the later stage of high-temperature processing (e.g., baking, sterilization) to avoid active ingredient loss;

pH: Suitable for neutral to weakly acidic formulations (pH 4.0-7.0); avoid strong acid/alkali environments to prevent polyphenol precipitation and activity reduction;

Storage: Mix with antioxidants (e.g., VE) in oil-based formulations; avoid long-term contact with metal ions (use glass/plastic containers) to prevent discoloration;

Beverages: Use water-soluble specifications, and avoid long-term mixing with high-sugar/high-alcohol systems to ensure stability.
