➢ Product Name: Green Tea Extract
➢ Latin Name: Camellia sinensis (L.) Kuntze
➢ Plant Part Used: Dried young leaves and buds of Theaceae Camellia sinensis
Manufactured from dried green-tea buds and leaves via sorting-impurity removal, low-temperature water-ethanol composite extraction, macroporous-resin adsorption and purification, vacuum concentration and aseptic spray-drying. It retains natural polyphenol active components of green tea, mainly including Epigallocatechin-gallate (EGCG), Epicatechin-gallate (ECG), Epigallocatechin (EGC) and Epicatechin (EC), together with accompanying components such as L-theanine and caffeine. No artificial monomer blending or exogenous auxiliary materials are added. It exerts free-radical scavenging, anti-oxidation, anti-inflammatory and lipid-metabolism-regulating effects, and is a widely-used botanical raw material in food and dietary-supplement industries. Different from ordinary tea crude powder, enriched extract features stable proportion of active components and multi-component synergism, meeting development demands for anti-oxidation maintenance and metabolic-regulation-related products.
➢ Raw Material Source: 100% extracted from green-tea buds and leaves, free of starch, dextrin and other exogenous additives.
➢ Processing Grade: Low-temperature first-grade refined extract. High-temperature-induced degradation of active substances is avoided; no artificial blending. Impurities, solvent residues, heavy metals and pesticide residues are controlled to meet food-relevant limit requirements.
➢ Core Indicators: Total tea polyphenols (UV) 20%-95%, EGCG (HPLC) 10%-75%; decaffeinated grades are available with controllable proportion of active components.
➢ Physical and Chemical Properties: Water-soluble fine powder; encapsulated modified products can be supplied to improve oxygen resistance and mask bitterness for multiple dosage-form development.
➢ Applicable Dosage Forms: Tablets, capsules, solid beverages, pressed candies, compound powders and others.
➢ Storage Properties: Sealed, light-proof and moisture-proof; store in cool and dry place. Avoid high temperature and oxygen exposure to guarantee activity stability.
➢ Authentic Raw Material, High-purity & High-activity:
Adopt green-tea buds and leaves from major tea-producing areas with proper maturity and high intrinsic polyphenol content to control raw-material quality from the source.
➢ Low-temperature Activity Lock, Natural Components:
Mild extraction and resin-enrichment processes reduce oxidative degradation of catechins. Intrinsic active-component ratio of tea is preserved; synergistic performance of natural compound system is superior to single monomer.
➢ Zero-adulteration Purity, Safe & Compliant:
Free of blending, fillers, pigments, flavors, preservatives and harmful auxiliaries. Strictly control residues and microorganisms, complying with requirements for domestic health-food raw materials, food additives and overseas pharmacopoeia standards.
➢ Strong Compatibility, Full-scenario Adaptation:
Stable physicochemical properties. Usable alone or compounded with other botanical extracts. Mainly applied in aqueous systems; encapsulated modification expands partial oil-system adaptability for multi-category product development.
➢ Standardized Production, Stable Batch Quality:
Produced in 100,000-class GMP workshop. Tested by HPLC and UV dual-methods. Key indicators including tea polyphenols and EGCG are strictly controlled for uniform batch quality and full traceability.
Uniform fine powder from light yellow-green to brown-tan with natural material color, loose, delicate and good fluidity. Possesses characteristic fresh aroma of green tea, free of scorched, mildewed or rancid peculiar odor. Conventional grades feature good water solubility, while high-purity tea polyphenols are prone to discoloration when contacting iron ions. Encapsulated modified products can mask bitter taste and enhance processing tolerance. Overall quality is superior to simply crushed tea crude powder.
Multi-component synergistic effect. Catechin-centered polyphenol system delivers powerful anti-oxidant capacity. Individual catechin monomers differ in physicochemical activity; compound system achieves better comprehensive performance than single EGCG monomer. The raw material is sensitive to oxygen, high temperature and metal ions. Encapsulation modification greatly improves processing tolerance, making up for the defect of easy deactivation of ordinary anti-oxidant raw materials.
Good compatibility in formulation. Conventional water-soluble grades are mostly used for solid beverages and instant products; high-purity grades fit for tablets and capsules; encapsulated modified products mask bitter taste and improve thermal stability, suitable for hot-processing procedures such as pressed candies; decaffeinated grades adapt to formulas requiring caffeine-intake control. Compatible with most industrial-production processes to satisfy mass-production and high-end customized development.
Food-grade high-barrier light-proof packaging isolates oxygen, light and moisture to reduce risks of polyphenol oxidation discoloration and moisture caking. Store at cool room temperature without freezing. Finish consumption promptly after opening. Flexible packaging specifications support lab-scale R&D, pilot test and large-scale production.
Green-tea polyphenols (catechin complex), mainly EGCG, ECG, EGC and EC, accompanied by L-theanine and caffeine. Synergy of multiple components forms the material basis for anti-oxidation, anti-inflammation and metabolic regulation.
Multiple phenolic hydroxyl groups in catechin molecules directly scavenge reactive-oxygen free radicals and inhibit lipid peroxidation. Meanwhile, they up-regulate activities of endogenous antioxidant enzymes such as SOD and glutathione to build anti-oxidant defense, alleviate cell damage induced by oxidative stress and retard cellular oxidative aging.
Modulate NF-κB signaling pathway, down-regulate release of pro-inflammatory factors including TNF-α and IL-6, inhibit chronic low-grade inflammatory response in vivo and mitigate inflammatory damage induced by oxidative stress.
Catechins interfere with lipid absorption and metabolism-related pathways, modulate lipogenesis and lipolysis processes, assist in regulating bodily lipid levels and help maintain metabolic homeostasis.
Polyphenol components act on cell membranes, mitigate free-radical attack against membrane lipids, preserve cell-membrane integrity and reduce cell damage caused by external oxidative stimuli.
L-theanine cooperates with catechins to soothe bodily stress response and modulate neural excitability, exerting auxiliary conditioning effects beyond anti-oxidation.
Raw material for anti-oxidation health foods, applied in capsules, tablets, solid beverages and other dosage forms, suitable for crowds requiring anti-oxidation maintenance.
Common botanical raw material for domestic and overseas dietary supplements featured with natural anti-oxidation maintenance. Developable into tablets, capsules and compound powders targeting consumers for daily sub-health care.
