In modern functional food, beverage, and clinical nutraceutical manufacturing, sourcing raw botanical powders requires far more than generic agricultural processing. As a pioneering China Top Fruit Extract Manufacturer & Exporters, Shaanxi Torzi Biotech integrates full-spectrum bioactive retention with multi-stage thermodynamic isolation. Our Xi'an factory utilizes multi-stage countercurrent extraction and specialized thin-film vacuum concentration systems designed to safeguard thermolabile bioactive molecules—such as anthocyanins, polyphenols, ascorbic acid co-factors, and essential carotenoids—against thermal degradation and oxidative polymerization.
Every commercial batch is produced in accordance with strict international pharmacopeia standards (USP, Ph. Eur., and JP). By implementing high-efficiency chromatography assays alongside comprehensive solvent-residue strip-down protocols, we ensure complete purity and batch-to-batch homogeneity across metric-ton contract manufacturing orders.

As consumer demand transitions toward clean-label transparency, rigorous heavy-metal scrutiny, and verifiable clinical efficacy, strategic B2B sourcing in China is undergoing profound transformation.
Brand owners are actively eliminating conventional maltodextrin and silica flow agents. The demand for 100% pure botanical powders, utilizing spray-freeze technology or soluble native fruit fibers as natural drying matrices, has surged across the North American and European nutraceutical markets.
Replacing toxic organic solvents with green chemistry is now mandatory. Subcritical water extraction (SWE) and pectinase-assisted cellular lysis release high-potency anthocyanins and polyphenolic compounds at lower temperatures, preserving native antioxidant capacities without petrochemical residues.
EU and FDA compliance requirements have intensified regarding sterilization residues. Modern Chinese manufacturers rely on low-temperature high-pressure pasteurization (HPP) and continuous microwave sterilization to maintain microbiological integrity while ensuring zero residual 2-chloroethanol.
Adulteration with synthetic dyes or lower-cost botanical lookalikes represents a premier regulatory vulnerability. Leading exporters now provide DNA barcoding alongside Stable Isotope Ratio Mass Spectrometry (IRMS) to prove authentic geographic botanical origin and non-synthetic botanical genesis.
Global brands with aggressive ESG mandates are driving the procurement of valorized fruit side-streams. Extracts harvested from cold-pressed juice pomace (e.g., citrus albedo, berry skins, and grape seeds) deliver superior polyphenol concentrations while meeting corporate carbon footprint benchmarks.
Procurement teams are shifting contracts from non-specific UV spectrophotometry total assays to precise multi-marker HPLC assays. Standardizing extracts to both primary biomarkers and secondary active flavanols guarantees real physiological bioefficacy in finished customer formulations.
Headquartered in Xi'an, adjacent to China's pristine Qinling Mountain botanical corridor, we combine 23+ years of extraction expertise with heavy capital investments in analytical instrumentation and cleanroom processing.

Every single commercial production lot undergoes exhaustive screening using triple-quadrupole GC-MS/MS and LC-MS/MS for over 500 multi-residue pesticides in accordance with USP <561> and European Pharmacopoeia (EP 2.8.13). Heavy metals (Lead, Arsenic, Cadmium, Mercury) are strictly quantified down to parts-per-billion (ppb) thresholds via atomic absorption and atomic fluorescence spectrometry, consistently satisfying California Proposition 65 and European Commission Regulation (EU) 2023/915 standards.
For bulk active ingredients and standardized fruit powders in stock, our MOQ starts at just 1 kg to 25 kg fiber drums, allowing formulation teams to conduct pilot trials and clinical validations at minimal capital risk. For contract custom packaging and private label finished dietary supplements (such as encapsulated formulas, stick packs, and customized bottles), our baseline MOQ starts from 500 to 1,000 commercial retail units with full packaging design support.
Natural fruit juices possess elevated concentrations of natural fructose and organic acids, which exhibit low glass transition temperatures (Tg) and absorb atmospheric moisture rapidly. To overcome caking and poor dispersibility in functional instant beverages, we implement specialized low-temperature vacuum belt drying, fluidized-bed agglomeration (instantizing), and microencapsulation with organic acacia fiber or non-GMO maltodextrin. Our powders dissolve completely in cold water within 30 seconds without sedimentation.
Yes. In addition to our factory Certificate of Analysis (COA) issued by our certified in-house laboratory for every batch, we regularly collaborate with globally accredited testing institutions including SGS, Eurofins, and NSF International. We provide clients with blind pre-shipment testing reports covering assay potency, microbiological limits (TAMC, TYMC, Salmonella, E. Coli), aflatoxins, and irradiation verification.
Every export dispatch includes an exhaustive regulatory documentation dossier: Batch-Specific Certificate of Analysis (COA), Safety Data Sheet (SDS/MSDS) compliant with GHS, Flow Chart of Manufacturing, Technical Specification Sheet, Non-GMO Statement, Allergen Declaration, BSE/TSE Free Certificate, and official Phytosanitary & Health Certificates issued by China Customs (GACC). Country of Origin declarations (Form A, Form E, or RCEP) are provided for preferential tariff clearance.
For standard botanical catalog items kept in constant inventory across our Xi'an, Shanghai, and Qingdao warehouses, dispatch occurs within 3 to 5 business days upon order confirmation. Custom extraction runs or private label encapsulation contracts requiring tooling modifications, custom pouch printing, or stability batch validation typically require 15 to 25 business days from final digital proof sign-off.
