Standardized 9-Step Extraction & Processing Workflow
Every botanical lot is processed through automated stainless-steel lines under strict critical control points.
Step 01 Raw Material Quarantine
Origin-sourced botanicals verified for botanical identity, moisture content, visual cleanliness, and pesticide pre-screening upon arrival.
Step 02 Solvent Extraction
Optimized hydro-ethanolic or pure water extraction in stainless-steel tanks with exact control over solvent ratio, temperature, and residence time.
Step 03 Vacuum Concentration
Low-temperature vacuum evaporators concentrate botanical liquor while preserving thermosensitive polyphenols, pigments, and bioactive fractions.
Step 04 Column Purification
Macroporous adsorption resins and ultrafiltration membrane modules isolate target chemical markers and strip undesirable tannins or heavy impurities.
Step 05 Drying & Spraying
High-capacity centrifugal spray towers convert liquid concentrate into free-flowing, instantly soluble micro-granules with strictly regulated water activity.
Step 06 Precision Pulverizing
Industrial impact and air-classifier mills grind dry materials into homogeneous powders suited for capsules, tablets, or instant beverage dispersions.
Step 07 Graded Sieving
Multi-deck vibratory screens classify powder mesh sizes (80 mesh up to 450 mesh) coupled with in-line neodymium rare-earth magnet separators.
Step 08 Homogeneous Mixing
Three-dimensional and ribbon mixers thoroughly standardize active compound percentages across multi-ton production batches or custom formulation blends.
Step 09 Packaging & Final QC
Cleanroom packaging in double food-grade polyethylene lined vacuum foil bags and fiber drums, followed by QA release verification and batch COA signing.
Industrial Equipment & Processing Machinery
Built with 304/316L sanitary stainless steel to ensure absolute purity and compliance with food-grade sanitary standards.
In-House Analytical Laboratory & Instruments
Staffed by 7 dedicated QA/QC chemists and 4 R&D engineers, our testing facility verifies molecular purity, residual solvents, heavy metals, and microbiology.
| Testing Parameter | Analytical Instrument | Verification Purpose |
|---|---|---|

| Residual Solvents Screening | Gas Chromatography (GC) with FID | Ensures ethanol, methanol, ethyl acetate comply with USP/EP monographs. |
| Total Polysaccharide & Color | UV-Vis Spectrophotometer | Measures mushroom glucans, phycocyanin E-value, and plant pigment absorption. |
| Heavy Metals (Pb, As, Cd, Hg) | Atomic Absorption / ICP-MS (Partner) | Enforces strict EU regulation 2023/915 and US FDA food contact thresholds. |
| Microbiological Safety | Class 10,000 Clean Bench & Incubators | Plate count, Yeast & Mold, Salmonella, E. coli, and Staphylococcus aureus. |
| Moisture & Ash Content | Halogen Moisture Meter & Muffle Furnace | Validates Loss on Drying (≤5%) and Total Ash residue (≤5%–9%). |
| Pesticide Multi-Residue | BS EN 15662 Standard (via SGS) | Multi-residue screening validating Organic and conventional tea/herb compliance. |
