Specific Examples (Raw Materials/Categories) |
|
Raw Material Control |
40 years of experience has established a standardized "Procurement - Testing - Traceability" system; every batch of raw material undergoes three-step verification: "Traceability + Visual Inspection + Preliminary Activity Testing" |
- Ginkgo biloba leaves: Mature autumn leaves (ensuring qualified flavonoid glycosides and terpene lactones) |
|
Full-Category Supply |
Dual model of "In-house Production + Strategic Partnerships" covering multi-industry needs. Partner factories undergo strict qualification audits + joint quality control. |
- In-house production: Core categories (such as the above four extracts) |
II. Raw Material Control: 40 Years of Expertise at the Source
Over four decades of raw material experience has enabled us to establish a standardized system from sourcing to warehouse inspection. For core categories, we implement precise traceability and control. Every batch undergoes origin tracing, appearance screening, and preliminary activity testing, ensuring quality from the source.
III. Category Expansion: In-house Production + Collaborative Partnerships
Beyond our core in-house categories, we have built long-term strategic partnerships with top manufacturers, expanding into fruit and vegetable extracts, Chinese herbal extracts, and spice extracts. With strict partner qualification reviews and joint inspections, we create a full-category supply model: "Core categories in-house, specialty categories through collaboration."
IV. Core Processes: Precision Extraction, Preserving Natural Bioactivity
- Pre-treatment: Low-temperature drying preserves activity; ultrafine grinding (80–120 mesh) breaks cell walls.
- Extraction: Dynamic countercurrent extraction with food-grade solvents at 40–60℃ for 2–4h. Compared to traditional methods, yields increase by 30%+.
- Purification: Multi-stage membrane separation (500–1000 Da cutoff) + low-temperature vacuum concentration (≤50℃).
- Formulation:
• Powder extracts: Spray-dried (inlet 180℃, outlet 80℃, solubility ≥98%)
• Liquid extracts: Sterilized via 0.22μm filtration, purity ≥99%
• Paste extracts: Vacuum-concentrated to 12–18% moisture, ensuring stability
All processes use closed systems to prevent contamination, ensuring purity and safety.
V. Quality Control: Certified and Fully Traceable

VI. Product Applications: Multiple Forms, Full-Scope Solutions
Based on the application characteristics of different industries, we have developed a multi-form product portfolio for our core extracts:
- Powder Extracts: Suitable for solid beverages, compressed candies, health foods, and dietary supplements; can be directly mixed for use.
- Liquid Extracts: Ideal for oral liquids, functional beverages, cosmetic essences, and pet health products; easily soluble and integrable.
- Customized Extracts: Adjustable according to customer needs, such as active ingredient levels (e.g., ginkgo biloba extract standardized to 24% or 36% flavonoid glycosides), particle size, and solubility, providing personalized solutions.
From raw material selection to process implementation, from quality control to product diversification, Evergreen is committed to "providing customers with high-quality, reliable plant extracts." With 40 years of industry experience and continuous technological advancement, we have become the preferred partner for clients worldwide in the plant extract sector.
