View Product SpecsThe Paradigm Shift: From Bulk Isolates to Bioactive Molecular Fractions
The global proteins landscape has moved beyond crude macro-nutrition. High-performing consumer brands require targeted molecular profiles, superior digestibility (DIAAS > 1.0), and certified functional attributes.
Enzymatic Specificity Over Acid Hydrolysis
Traditional thermal and acid hydrolysis causes amino acid racemization, generating undesirable L-to-D conversions and toxic lysinoalanine complexes. Modern manufacturing protocols employ high-specificity endo- and exo-proteases at controlled temperature and pH, safeguarding essential chain sequences such as Gly-Pro-Hyp and ensuring predictable bio-accessibility without residual chemical precipitants.
Hybrid Matrix & Synergistic Cleavage
Modern formulators are actively blending plant-derived isolates (pea, rice, wheat) with specialized animal derivatives (marine collagen, sea cucumber peptides). Combining animal-derived structural oligopeptides with branched-chain rich pulse proteins overcomes individual DIAAS deficiencies, minimizing systemic allergen exposure while providing complete essential amino acid matrices.
Clean-Label Odor & Color Rectification
The inherent obstacles in protein commercialization—beany off-notes from legume hexanal volatiles, or fishy trimethylamine residues in marine peptides—are resolved at source. Utilizing continuous countercurrent extraction, membrane nanofiltration, and low-temperature deodorization yielding crystalline, neutral-tasting powders that dissolve into crystal-clear beverage and topical solutions.

Enterprise Sourcing Architecture: Mitigating Formulation & Regulatory Risk
Global procurement heads require verifiable technical predictability. Our end-to-end quality validation protocols exceed standard pharmacopeia expectations.
Heavy Metal & Contaminant Guard
Every single manufactured lot passes ICP-MS spectral quantification to guarantee Lead <0.5 ppm, Arsenic <0.5 ppm, Cadmium <0.1 ppm, and Mercury <0.05 ppm, meeting strict Proposition 65 thresholds and EU Regulation (EC) No 1881/2006 for clinical nutritional safety.
Validated Molecular Cutoff (MWCO)
Gel Permeation Chromatography (GPC) curves are generated per batch to verify exact Dalton distributions. Our closed-loop ceramic membrane cassettes isolate specified fractions (e.g., 500–1,500 Da) without high-molecular agglomerates that impair topical skin penetration or enteric uptake.
Sterility & Bio-Burden Control
Triple filtration followed by high-temperature, short-time pasteurization (HTST) achieves complete bacterial elimination without thermal protein denaturation. Total Plate Count is maintained below 1,000 CFU/g with non-detectable yeast, mold, Salmonella, and E. coli per USP <61/62>.
Export Document Dossiers
Every commercial invoice includes full-parameter batch COA, Allergen Declarations, Non-GMO Statements, Safety Data Sheets (SDS), BSE/TSE-Free Certificates, Kosher / Halal validations, and full INCI/CAS registration dossiers for seamless customs clearance.
Formulation Solutions Across High-Impact Industrial Sectors
From transdermal cosmetic bioavailability to instant dispersibility in beverage applications, we tailor physical parameters to resolve formulation friction.
Hair Cortex Restoration & Cuticle Sealing
Hydrolyzed wheat and pea protein fractions possess balanced amphoteric charges that electrostatically bind to damaged, negatively charged keratin filaments. In shampoo and rinse-off treatments, our low-Dalton wheat peptides penetrate deep into the hair cortex, enhancing tensile strength and moisture-holding capacity, while medium peptides form a protective moisture shield against thermal and chemical stress.
Sports Hydration & Medical Clinical Nutrition
Intact proteins require extensive pancreatic digestion, slowing nitrogen balance restoration in post-surgical or elderly recovery states. By pre-hydrolyzing plant (rice, pea) and marine animal matrices into targeted di- and tri-peptides, mucosal peptide transporters (PepT1) absorb nitrogen directly, expediting plasma amino acid clearance, boosting myofibrillar protein synthesis, and eliminating gastrointestinal distress.
Cosmeceutical Skin Barrier & Anti-Wrinkle Actives
Our bio-active tripeptide and octapeptide series (including Acetyl Octapeptide-3, Pro-xylane, and GHK-Cu complexes) modulate fibroblast proliferation and glycosaminoglycan synthesis in the dermis. Paired with non-greasy hydrolyzed sunflower and peanut extracts, they reinforce epidermal lipid lamellae, inhibit matrix metalloproteinases (MMP-1), and restore cellular elasticity.
Technological Frontiers: Precision Cleavage & Green Synthesis
Pioneering sustainable extraction processes and AI-guided bio-enzymatic mapping to ensure future-ready ingredient security.
In Silico Proteolytic Cleavage Mapping
By leveraging computational structural biology and molecular docking algorithms, we map target cleavage sites along raw polypeptide chains before pilot bio-fermentation. This precision directs enzyme cocktail formulations to consistently liberate exact peptide sequences, avoiding trial-and-error yield losses and maximizing batch-to-batch biological repeatability.
Zero-Effluent Circular Extraction
Our 60,000 m² factory complex is transitioning into a closed-loop bio-refinery model. Upcycling agricultural side-streams (such as seed press-cakes and defatted oilseed residues) through enzyme cascades isolates both proteins and high-purity polyphenols, while integrated vapor-recompression evaporators recover 92% of operational water for sustainable, EcoVadis-audited manufacturing.
Micro-Encapsulated Peptidic Stabilizers
To eliminate cross-reactive oxidation in complex functional emulsions, we are implementing low-temperature fluid-bed lipid micro-encapsulation. This physical shielding protects sensitive terminal amine groups during extrusion, pasteurization, and prolonged shelf life, releasing the functional peptide intact at the target physiological pH.
Enterprise Buyer Inquiries: Quality, Scale, and Regulatory Alignment
Comprehensive answers designed to accelerate supplier audits, analytical validations, and commercial onboarding.
We combine tailored endo/exo-protease enzymolysis with continuous multi-stage tangential flow ultrafiltration membranes (Ceramic MWCO 10kDa, 5kDa, 3kDa, and 1kDa). GPC chromatograms verify that >85% of our hydrolysates reside strictly within the requested Dalton boundary, avoiding unhydrolyzed proteins or hyper-cleaved free amino acids.
Yes. We regularly formulate to client-specified bulk densities, mesh sizes (from 80 to 200 mesh), dispersibility ratings, and liquid concentrations (20% to 50% solids). Furthermore, active marker levels, specific enzyme inactivities, and low-sodium limits can be custom engineered at our Xi'an R&D center.
Every single commercial shipment is accompanied by a formal lot-specific Certificate of Analysis (COA) confirming HPLC/Kjeldahl assay, heavy metals (ICP-MS), residual solvents (GC-MS), and micro-burdens. Production is compliant with cGMP, ISO9001, ISO22000, Kosher, Halal, and EcoVadis guidelines.
Through low-temperature vacuum flash deodorization combined with porous activated carbon and macro-porous resin adsorptions. This completely strips short-chain aldehyde volatiles and amines responsible for bitter or fishy notes without altering active amino acid profiles.
Operating six multifunctional production lines across our 60,000 m² site, our annual hydrolysate capacity reaches approximately 3,000 metric tons. Standard catalog items ship within 3–5 business days, while custom pilot-to-bulk synthesis runs require 2 to 3 weeks depending on testing protocols.
We supply qualified formulators with 50g–500g analytical trial samples alongside comprehensive technical dossiers—including HPLC chromatograms, SDS/MSDS, TDS, stability data, and recommended inclusion rates—to accelerate bench testing and regulatory filing.
