R&D Insights: Balancing Active Potency, Solubility & Pesticide Safety
Technical notes from our natural phytonutrient extraction & polyphenol standardization team.
Green Tea Extract (Camellia sinensis) is widely recognized as a benchmark antioxidant ingredient in weight management, functional beverages, and cellular health formulations. However, sourcing market-ready Green Tea Extract presents serious procurement hurdles: heavy pesticide residues (such as Endosulfan and Anthraquinone), high bitterness, astringency, and turbidity upon aqueous dissolution.
Our facility uses continuous membrane separation combined with low-temperature countercurrent extraction. This clean physical process preserves fragile epigallocatechin gallate (EGCG) molecules while removing excess chlorophyll, astringent tannins, and bitter caffeine when necessary. We deliver crystal-clear water solubility, strict EU/USP pesticide compliance, and stable polyphenol content-providing brand owners with a versatile bulk ingredient tailored for capsules, functional RTD beverages, and dietary stick packs.

Frequently Asked Questions (FAQ)
Q1: How do you control pesticide residues to comply with European regulations?
A: We manage our supply chain from the raw leaf cultivation stage at GAP-certified tea plantations. Combined with physical supercritical extraction and resin purification, we screen every batch against EU EC 396/2005 multi-pesticide standards before release.
Q2: What is the main difference between HPLC and UV testing methods for Green Tea Polyphenols?
A: UV spectroscopy measures total polyphenols in aggregate, whereas HPLC separates and quantifies specific active monomers like EGCG, ECG, EGC, and EC. We provide both testing methods on our COAs to match your specification needs.
Q3: Can your Green Tea Extract Powder be completely dissolved in cold liquid beverages?
A: Yes! Our Instant Beverage Grade Green Tea Extract undergoes membrane filtration and spray-drying, enabling complete, clear dissolution in room-temperature or cold water without cloudiness, precipitation, or heavy floating residues.
Q4: Is decaffeinated Green Tea Extract chemically processed?
A: No, we utilize physical food-grade ethyl acetate or resin column separation to selectively extract caffeine down to <0.5%, preserving the original catechins and polyphenols without using toxic aromatic solvents like dichloromethane.
Q5: How can our technical or procurement team request trial samples?
A: Fill out the inquiry form below or send us a message. We will dispatch a 100g sample kit along with full batch COAs, HPLC chromatograms, and safety data sheets within 24–48 hours.
