What is Green Tea Extract Powder?
Green Tea Extract Powder represents the premium end of green tea ingredient supply — a concentrated, standardized extract offering consistent bioactive potency across batches for professional formulation.
The product is produced by water extraction of 100% green tea leaves (Camellia sinensis), preserving the full spectrum of green tea’s bioactive compounds. The extract is then carefully spray-dried or vacuum-dried into a fine, free-flowing powder with a light brown to yellow-brown appearance, characteristic mild green tea flavor, and good water dispersibility.
The Key Bioactive: EGCG
EGCG (epigallocatechin gallate) is the most abundant and pharmacologically active catechin in green tea — responsible for the majority of green tea’s well-researched health benefits. As a potent antioxidant, EGCG helps protect cells and tissues from oxidative damage caused by free radicals. Research published in peer-reviewed journals including the Journal of Nutritional Biochemistry and Free Radical Biology & Medicine has explored EGCG’s role in supporting metabolic health, cardiovascular function, and cellular protection.
Standardization Options
ORGANICWAY offers flexible standardization to meet diverse formulation needs:
- Total Polyphenols: 50–98% (customizable)
- EGCG: 20–50% (customizable)
- Extraction Ratio: 10:1 to 20:1 (customizable based on specification)
Higher standardization (e.g., 50% EGCG) is preferred for concentrated capsule and tablet formulations where maximum potency per gram is required. Lower standardization (e.g., 50% polyphenols with 20% EGCG) may be preferred for food and beverage applications where a broader polyphenol profile and milder flavor are desirable.
Caffeine Options
Three caffeine profiles are available to serve different product positioning needs:
- Standard Caffeine: 2–10% caffeine — for energy and focus product lines
- Low Caffeine: <1% caffeine — for sensitive consumer segments
- Decaffeinated: Near-zero caffeine — for caffeine-free formulations
Applications
The extract’s versatility spans dietary supplements (capsules, tablets, powders), functional beverages (RTD drinks, powdered mixes, energy drinks), functional foods (energy bars, cereals, snacks), and topical cosmetics (antioxidant skincare formulations). Its excellent water solubility makes it particularly suitable for liquid and powdered product formats.
The product carries Non-GMO, and comprehensive Allergen-Free certifications (Gluten-Free, Dairy-Free, Soy-Free, Nut-Free), making it suitable for clean-label and allergen-sensitive finished product lines.

EGCG and Health Claims Note: EGCG antioxidant and metabolism-related claims are supported by general antioxidant research and structure-function evidence. Cardiovascular, weight management, and performance claims require review against local regulations (FDA, EFSA, etc.) for finished product labeling. “EGCG” as a named ingredient is widely accepted in supplements; specific efficacy claims should be validated with regulatory counsel.

Formulation Notes
- Solubility: The extract disperses well in water, making it suitable for both liquid and powder formats. For clear beverages, testing is recommended as some standardization levels may impart a light color.
- Flavor Profile: Characteristic mild green tea flavor with slight bitterness — more pronounced at higher EGCG levels. Citrus (lemon, orange), mint, ginger, and berry flavors mask or complement green tea bitterness effectively.
- pH Stability: Polyphenols and EGCG are most stable at pH 4–6. Avoid highly alkaline formulations (pH > 8) which accelerate polyphenol oxidation and discoloration.
- Heat Stability: EGCG is heat-stable under standard HTST pasteurization. Avoid prolonged boiling or retort processing which may degrade sensitive catechins.
- Light Sensitivity: EGCG is light-sensitive. Store in opaque or amber packaging and use oxygen-barrier bottles for finished products to prevent oxidation.
- Synergy with Vitamin C: Ascorbic acid (vitamin C) significantly enhances EGCG stability and antioxidant effectiveness — consider co-formulation in beverages and supplements.
- Protein Binding: EGCG can bind with proteins and may cause cloudiness in dairy-based or high-protein formulations. Test compatibility with your specific matrix.
- Caffeine Considerations: The caffeine content of your finished product must be accounted for in labeling — especially for children’s products, bedtime formulations, or caffeine-sensitive consumer segments.
FAQ
Q: What is EGCG, and why is it important in Green Tea Extract?
A: EGCG (Epigallocatechin Gallate) is the most abundant and biologically active catechin (a type of polyphenol) found in green tea. It’s a powerful antioxidant responsible for many of green tea’s purported health benefits, including supporting metabolism, heart health, and cellular protection.
Q: Can I get Green Tea Extract Powder with specific EGCG or Polyphenol percentages?
A: Yes, we offer Green Tea Extract Powder with customizable standardization options for both Total Polyphenols and EGCG content, allowing you to meet your precise formulation requirements.
Q: What’s the typical shelf life and recommended storage for bulk quantities?
A: Our Green Tea Extract Powder typically has a shelf life of 24-36 months from the manufacturing date when stored in a cool, dry place, away from direct sunlight and moisture, in its original sealed, airtight packaging.
Q: Is your Green Tea Extract Powder non-GMO and allergen-free?
A: Yes, Our Green Tea Extract Powder is inherently Non-GMO. It is also naturally free from most common allergens like gluten, dairy, soy, and nuts, making it suitable for broad application in “free-from” products.
Q: Is the caffeine content always high in green tea extract?
A: No, we offer Green Tea Extract Powder with various caffeine levels, including standard, low caffeine, and decaffeinated options. This flexibility allows you to choose the extract that best suits your product’s purpose and target audience.
Q: Does green tea extract always contain high levels of caffeine?
No. ORGANICWAY offers multiple caffeine level options: standard caffeine (2–10%), low caffeine (u0026lt;1%), and decaffeinated (near-zero). The choice depends on your product’s target consumer, positioning (energy vs. wellness), and regulatory requirements for caffeine labeling. Decaffeinated options enable caffeine-free formulations for children’s products, bedtime supplements, and general wellness lines.
Q: What is the difference between green tea extract and green tea powder?
Green tea extract is a concentrated botanical extract — water is used to pull the active compounds (polyphenols, EGCG, caffeine) from green tea leaves, then the extract is dried into a powder. This process concentrates the bioactive constituents (often 10:1 to 20:1 ratio), delivering standardized, measurable doses of EGCG and polyphenols in a small amount of powder. Green tea powder, by contrast, is made by simply grinding dried green tea leaves — it contains the full leaf matrix including fiber and is much less concentrated. Extract is preferred for supplements and standardized functional products; powder is preferred for food applications where whole-leaf authenticity is desired.
Q: Is this product suitable for Vegan finished products?
Yes. Green Tea Extract Powder is 100% plant-based — produced from green tea leaves with water extraction and no animal-derived inputs. It is confirmed Vegan and suitable for Vegan-certified finished products.
Q: What is the minimum order quantity and lead time?
MOQ is 25 kg. Standard lead time is 10–20 business days from order confirmation. Free samples are available upon request, shipped via FedEx, UPS, or EMS.
