Shaanxi Torzi Biotech: Advanced Plant Extraction Infrastructure
Operating directly out of the Qinling Botanical Corridor in Xi'an, Torzi Biotech integrates raw agricultural harvesting, high-efficiency aqueous counter-current extraction, and high-purity molecular purification.
In-House Quality Control Laboratory
Every single batch is verified using advanced separation and identification instruments including HPLC (High-Performance Liquid Chromatography), Gas Chromatography (GC) for solvent traces, and Atomic Absorption Spectrometry (AAS) to verify heavy metals (Pb, As, Cd, Hg) remain far below strict USP/EP thresholds.
SGS On-Site Audited Facility
Unlike secondary brokers or trading offices, our manufacturing operations are evaluated directly on-site by SGS Group. We retain complete tracking archives from fresh agricultural receipt through crystallization, spray drying, and nitrogen-purged hermetic sealing.
Flexible OEM/ODM Formulations
We provide full-spectrum contract packaging services, from raw spray-dried instant powders in 25 kg fiber drums down to custom private-label unit stick-packs, sachets, vegetarian pullulan capsules, and customized herbal blends with minimum MOQs starting at 500 units.

Technological Evolution of Herbal Tea Extracts & Instant Botanical Solids
A technical overview of modern botanical processing: overcoming sedimentation, astringency degradation, and active compound denaturing during commercial production.
1. Low-Temperature Dynamic Extraction
Traditional high-heat boiling severely hydrolyzes delicate tea polyphenols, theaflavins, and aromatic terpenes. As a high-tier factory, we deploy multi-stage closed-circuit low-temperature vacuum circulation (40°C–55°C). This process ensures sensitive phenolic rings, polyphenols, and aromatic esters remain undamaged while preventing unwanted caramelization of naturally occurring monosaccharides.
2. Ceramic Membrane & Haze Prevention
Instant herbal tea extracts and RTD (Ready-To-Drink) beverages frequently suffer from post-dilution cloudiness caused by polyphenol-protein macromolecular complexes ("tea cream"). Our production workflow integrates 0.05-micron ceramic microfiltration followed by high-speed disc centrifugal separation (12,000 RPM) to eliminate insoluble colloidal haze while keeping the final liquid 100% translucent in both cold and hot aqueous dissolution.
3. Microencapsulation & Controlled Spray-Drying
High hygroscopicity is the leading failure vector during bulk powder storage. By employing nitrogen-blanketed low-temperature spray drying with optional non-GMO soluble dietary fiber carriers, our instant tea extracts achieve controlled bulk densities (0.40–0.60 g/mL) and free-flowing properties that prevent caking, extending stability past 24 months without synthetic anti-caking agents.

Strategic Sourcing Whitepaper
Global Procurement & Formulation Trends (2025–2030)
How international pharmaceutical, nutraceutical, and functional beverage buyers are optimizing their botanical supply chains to mitigate supply volatility and meet stringent clean-label standards.
1. Shift Toward Verified Active Monomers
Global regulators and demanding health-conscious consumers are moving away from ambiguous botanical ratio claims (e.g., "10:1 ratio extract") in favor of analytically verified active compounds. Procurement teams now prioritize raw botanical ingredients containing validated titers of L-Theanine, Polyphenols, Betacyanins, Polysaccharides, or Steviol Glycosides confirmed by third-party HPLC monographs.
2. "Better-for-You" Functional Ready Mixes
The convergence of wellness tonics, herbal tea bases, and clean performance beverages has unlocked surging demand for multi-active premixes. Manufacturers now combine instant organic green or black tea extracts with potent botanical synergists such as Black Maca Root, Freeze-Dried Fruit Concentrates, and Marine Collagen Peptides to engineer comprehensive functional RTD beverage formulations.
3. Strict Heavy-Metal & Pyrrolizidine Limits
Regulatory updates across the European Union (Regulation EU 2020/2040) and California's Proposition 65 have established ultra-low thresholds for pyrrolizidine alkaloids (PAs) and environmental contaminants in tea-derived botanicals. Leading global procurement officers now exclusively partner with primary manufacturers possessing validated, documented raw source agricultural estates.
4. Carbon Footprint & Direct-to-Factory Chains
To insulate brand margins from currency fluctuations and international trade bottlenecks, global supply chain directors are bypassing overseas wholesalers. By dealing directly with primary Chinese extraction processors equipped with integrated R&D, brands secure immediate lot reproducibility, competitive ex-works pricing, and comprehensive batch documentation.

Frequently Asked Questions for Ingredient Buyers
Everything procurement officers, quality control teams, and formulation chemists need to verify before initiating contract manufacturing.
What is your standard Minimum Order Quantity (MOQ)?
For bulk catalog botanical extract powders, standard pilot-scale MOQs start from 1 kg to 25 kg fiber drums, allowing formulation testing in pilot pilot runs. For custom spray-drying batches, custom mesh sizing, or private-label encapsulated packaging, our production minimums start from 500 retail units or 100 kg of bulk active substance.
Do you issue a Certificate of Analysis (COA) for every batch?
Yes. Every single dispatch is accompanied by an authenticated Certificate of Analysis (COA) verifying active marker content via HPLC/UV, mesh size, loss on drying, bulk density, residual solvents (via Gas Chromatography), heavy metals (tested via AAS), and full microbiological counts. Third-party testing reports from Eurofins, SGS, or Pony Testing are provided upon contract request.
How do you guarantee cold-water instant solubility without caking?
We employ centrifugal molecular membrane filtration to eliminate natural hydrophobic lipid fractions, proteins, and long-chain colloidal insolubles. Subsequent fluid-bed agglomeration or low-temperature centrifugal spray drying with optimized moisture controls produces free-flowing granules that rehydrate immediately without clumping or lingering sedimentation.
What export documentation and certifications are provided?
Our facility holds verified USDA Organic, Halal, Kosher, and ISO9001/ISO22000 credentials, and has undergone on-site supplier verification audits by SGS. For customs clearance, we regularly supply full MSDS/SDS dossiers, Non-Irradiation Declarations, BSE/TSE-Free Certificates, Phytosanitary Certificates, and Certificates of Origin (CO/Form A/Form E).
Can you formulate proprietary functional blends or private label products?
Yes. We specialize in contract blending, dry homogenization, and unit dose filling. Whether blending instant tea polyphenols with functional marine peptides, adaptogenic root extracts, or natural steviol sweeteners, our Class 100,000 cleanroom workshops handle precision toll blending, capsule filling, and customized packaging.
How are samples dispatched and what are standard shipping lead times?
Complimentary evaluation samples (50g to 200g) are packaged in heat-sealed pharmaceutical aluminum foil pouches and dispatched globally via DHL, FedEx, or UPS within 24 to 48 hours. Bulk commercial shipments from current warehouse inventory ship within 3–7 business days via air freight or temperature-controlled sea freight.
