Product SpecificationsThe Triad of Biorefining: Protein Concentrates, Isolates, and Hydrolysates
Strategic industrial fractionation and molecular weight management from China's leading ingredient synthesis hubs.
Protein Concentrates (50%–75% Purity)
Engineered via gentle aqueous solvent extraction and air classification to retain essential dietary lipids, phospholipids, micronutrients, and native fibers. Ideal for bulk food texturization and complete nutritional profiles.
- Retains endogenous vitamins and trace minerals
- Cost-optimized for large-scale bar and baked formulations
- Superior water retention and emulsification matrices
Protein Isolates (80%–92% Purity)
Fractionated using isoelectric precipitation combined with cross-flow membrane ultrafiltration (UF) and microfiltration (MF). Removes non-protein carbohydrates, antinutritional oligosaccharides, and undesirable off-flavor volatiles.
- Hypoallergenic, ultra-low lipid and ash fractions
- High Branched-Chain Amino Acid (BCAA) retention
- Exceptional dispersibility in ready-to-mix (RTM) beverages
Protein Hydrolysates (Enzymatic Peptides)
Targeted bio-cleavage of polypeptide chains utilizing precise endopeptidases and exopeptidases. Yields predetermined molecular weight distributions (<1,000 to 3,000 Daltons) designed for rapid cellular absorption.
- Low molecular mass tailored for immediate metabolic delivery
- Reduced antigenicity for hypo-allergenic and clinical nutrition
- High surfactant capabilities for hair care & cosmetic penetration

Global Sourcing Challenges & Industrial Solutions
Addressing supply chain friction, regional compliance barriers, and functional performance inconsistencies.
Hydrolysate Bitterness & Off-Notes
Challenge: Hydrophobic amino acids (Leucine, Phenylalanine) exposed during enzymatic scission create bitter notes that fail consumer taste evaluations.
Factory Solution: We employ a dual-phase, selective exopeptidase enzymatic cleavage combined with activated carbon decolorization and proprietary flash-vacuum deodorization columns, ensuring pure flavor neutrality.
Batch-to-Batch Viscosity Inconsistencies
Challenge: Variance in crop harvest conditions creates fluctuations in protein quaternary structure, yielding unpredictable gelation in liquid beverage lines.
Factory Solution: Integration of automated inline FT-NIR process sensors and precision standardized shear homogenizers ensures constant dynamic viscosity (cP) across all scaled manufacturing batches.
Complex Cross-Border Compliance
Challenge: Stringent heavy metal limits (USP/EP), non-GMO verification, and pesticide multi-residue panels (EU Regulation EC 396/2005) cause port rejections.
Factory Solution: Routine batch testing via ICP-MS for heavy metals (<10ppb detection), third-party Eurofins/SGS cross-validation, and provision of full regulatory dossiers (CoA, MSDS, TSE/BSE, Allergen Declarations).

Product SpecificationsEnterprise Sourcing & Compliance FAQ
Essential guidance for formulation scientists, quality controllers, and global supply managers.
How is the Degree of Hydrolysis (DH) controlled in bulk manufacturing?
DH is tightly modulated using automated pH-stat titration and enzyme termination via thermal inactivation (HTST). We monitor cleavage extent using the TNBS (trinitrobenzenesulfonic acid) and OPA (o-phthaldialdehyde) methods to verify precise peptide length distribution.
What quality dossiers are provided for European novel food qualification?
Every commercial batch is accompanied by a full technical package: batch-specific Certificate of Analysis (COA), safety data sheet (SDS/MSDS), non-GMO declaration, allergen declaration, flowchart documentation, and pesticide multi-residue panels analyzed under DIN EN 15662.
What is the minimum order quantity (MOQ) and packaging standard?
Our standard pilot testing MOQ is 25 kg packed in double food-grade polyethylene lined vacuum-sealed bags within robust fiber drums. Commercial container-load configurations (FCL) feature 500 kg to 1,000 kg palletized supersacks with desiccants.
Can you customize particle sizes (mesh) for specific dissolution speeds?
Yes. Utilizing specialized cryogenic air-classifying mills (ACM), we produce tailored particle sizes from standard 80 mesh up to ultra-fine 300–500 mesh, optimized for rapid cold-water dissolution without agglomeration.
How do you guarantee the absence of cross-contamination?
Our 60,000 m² plant is segmented into dedicated production bays. Each processing line incorporates automated Clean-In-Place (CIP) and Sterilize-In-Place (SIP) cycles validated by ATP swab and ELISA testing to avoid botanical or gluten cross-contact.
What are the lead times for custom spray-dried hydrolyzed formulations?
Standard catalog raw materials ship within 3–5 working days from our Xi'an warehouse. Custom enzyme cleavage profiles, specific molecular cut-offs, or dedicated spray drying trials require 14–21 calendar days from laboratory pilot approval to export departure.
