Primary Peptide & Active Raw Material Portfolio
Standardized, analytical-grade cosmetic peptides, botanical extracts, and bioactive plant protein fractions manufactured under strict cGMP protocols.
Collagen Peptide Science: Molecular Weight Distribution & Bioavailability Kinetics
The therapeutic and functional efficiency of collagen peptides is governed entirely by enzymatic cleavage specificity, terminal amino acid profiles, and molecular weight distribution measured via High-Performance Size Exclusion Chromatography (HPSEC).
Targeted Dalton Weight Tuning
Native collagen possesses a high molecular weight of ~300,000 Daltons with virtually zero oral permeability. Our ODM bio-enzymatic directional shearing reduces native triple-helix tropocollagen into bio-accessible peptide fragments tightly clustered between 1,000 and 3,000 Daltons. This guarantees accelerated trans-epithelial transport across intestinal enterocytes via the PEPT-1 transporter pathway without competitive degradation.
Bioactive Di-/Tri-Peptide Concentration
We specifically optimize cleavage yields for potent signaling oligopeptides, notably Prolyl-Hydroxyproline (Pro-Hyp) and Hydroxyprolyl-Glycine (Hyp-Gly). These biological fragments act as chemotactic triggers that interact directly with dermal fibroblasts, stimulating endogenous synthesis of Type I and Type III collagen, hyaluronic acid, and extracellular matrix proteoglycans.
Advanced Physical Granulation & Instant Solubility
Unprocessed collagen powders suffer from clump formation, hydrophobicity, and poor wettability. Through continuous multi-stage fluidized-bed agglomeration, our engineering team modifies powder bulk density (0.35–0.48 g/mL) to guarantee instant, crystal-clear cold-water dispersion within 12 seconds without foaming, off-odors, or sediment fallout in ready-to-mix (RTM) solutions.

China Factory Ecosystem: Scalable Precision Bio-Manufacturing
Xi'an Le-Nutra leverages raw material access, high-capacity enzymatic bioreactors, automated crystallization systems, and centralized logistics infrastructure to deliver cost parities and lead-time stability unmatchable by Western contract compounders.
Upstream Raw Material Aggregation
Our raw material sourcing spans traceable, non-GMO, antibiotic-free supply corridors: pasture-raised bovine hide/bone, cold-water deep-sea fish skin/scales (Cod, Tilapia), and avian cartilage. Direct procurement contracts ensure 100% veterinary inspection compliance, complete origin traceability, and immediate fresh processing within controlled cold-chain corridors.
Smart Automation & Bioreactor Capacity
Our 60,000 m² high-tech facility operates 6 automated extraction and enzymatic reaction trains. Controlled by Siemens SCADA automation, parameters including enzymatic cleavage pH (±0.05), cleavage temperature (±0.2°C), and enzyme inactivation are locked into computer-controlled sequences, achieving lot-to-lot consistency across 3,000 metric tons of annual peptide output.
Zero-Carbon Membrane Concentration
Rather than relying solely on thermal evaporation—which degrades delicate terminal amino acid sequences—our infrastructure employs low-temperature nano-filtration and reverse osmosis membrane loops to pre-concentrate peptide eluates. This reduces carbon footprint by 42% and retains bio-active polypeptide integrity before pressure spray-drying.
The 5-Stage Precision Cleavage & Purification Workflow
Every metric ton of ODM collagen peptides follows an immutable, monitored chain of custodial controls designed to eliminate organoleptic defects, heavy metal contamination, and microbial non-conformities.
Demineralization, gentle alkaline conditioning to remove non-collagenous proteins, and neutralization under ultra-pure RO water systems.
Proprietary protease endopeptidase and exopeptidase cocktails cleave high-mass helical protein chains into calibrated short-chain peptides.
Activated carbon decolorization and deodorization, coupled with diatomaceous earth and 0.22 μm sterile membrane microfiltration.
Low-temperature centrifugal atomization in a HEPA Class 100,000 cleanroom, paired with fluidized-bed aggregation for instant rehydration.
Full-spectrum analytical batch verification via LC-MS, ICP-MS, and GC-MS. Batch release accompanied by certified English COA and safety dossier.
Localization Architecture: Meeting Global Procurement Needs
Procurement directors and QA auditors face regulatory barriers across individual customs territories. Le-Nutra mitigates import friction through localized compliance engineering and tailored technical documentation.
North America (FDA FSVP / GRAS)
Full alignment with FDA 21 CFR Part 111 (Dietary Supplements) and Part 117 (FSMA cGMP). We supply Foreign Supplier Verification Program (FSVP) complete packages, comprehensive allergen declarations (major-9 compliant), Proposition 65 non-detection statements (toxic heavy metals < 0.1 ppm), and Self-Affirmed GRAS documentation for food and functional beverage integration.
European Union (EFSA & REACH)
Adherence to Regulation (EC) No 853/2004 for collagen products intended for human consumption. We issue BSE/TSE-free certificates from certified non-risk herds, vet health certificates authenticated by China Customs (GACC), radiation-free certificates, and non-animal origin verification statements for botanical peptide analogs.
Halal & Kosher Certification
To access high-growth consumer corridors in Southeast Asia, GCC countries, and North American ethnic retail segments, our dedicated collagen lines operate under strict MUI Halal, JAKIM Halal compatibility, and Star-K / OU Kosher rabbinical supervision, guaranteeing absolute non-contamination with porcine derivatives.
Formulation Matrix: Application Scenarios & Physical Compatibility
Our ODM engineering capabilities extend beyond delivering bulk powder; we formulate for physical chemistry, thermal stability, matrix cross-linking, and flavor neutralization across diverse commercial consumer channels.
Ready-To-Drink (RTD) Beverages
Formulating shelf-stable RTDs requires overcoming thermal precipitation during UHT sterilization and acid gelation in low-pH environments (pH 2.8–3.8). Our ultra-hydrolyzed marine and bovine grades remain 100% transparent and low-viscosity without clouding or bitter polypeptide development over 24-month ambient shelf cycles.
Nutricosmetic Functional Gummies
Integrating high protein loading into pectin or gelatin gummy matrix bases causes textural rubberiness and high water-binding competition. We supply custom low-hygroscopic collagen granules designed for 10%–20% active payload loading without compromising gel setting time or pectin elasticity.
Clinical Enteral & Senior Nutrition
Elderly populations and medical enteral patients require rapid protein synthesis with zero digestive burden. Our short-chain oligopeptides (<1,000 Da) bypass gastric acid denaturation barriers, facilitating rapid postprandial nitrogen retention and preventing muscle sarcopenia without elevating serum urea.
Industry Megatrends: The Shift to Precision Di-Peptide Formulations
Global collagen markets are transitioning from bulk, generic protein filler commodities to clinically authenticated, bioactive molecular therapeutics. Formulators must adapt to three structural consumer shifts.
Bioactive Micro-Dosing (Targeted Tripeptides)
Traditional collagen required consumer intakes of 5,000–10,000 mg daily. Technological breakthroughs in endo-protease sequencing now allow the concentration of Gly-Pro-Hyp (GPH) tripeptides, reducing the required clinical daily therapeutic dose to 1,000–2,500 mg while yielding equal or superior dermal elasticity and articular joint improvements.
Regenerative & Upcycled Biomass
Global beauty conglomerates are enforcing strict Scope 3 ESG targets. Le-Nutra leads this transition by utilizing upcycled aquaculture by-products (wild marine fish skins and aquaculture Tilapia scales) and regenerative cattle leather trims, minimizing organic waste while maintaining full physical and microbiological traceability.
Hybrid Botanical-Peptide Cross-Formulations
Formulators are moving away from single-ingredient SKUs. The fastest-growing market segments combine hydrolysed marine collagen with synergistic botanical actives—such as Le-Nutra's standardized Chamomile (Apigenin), Saffron (Safranal), and Pomegranate (Ellagic Acid)—creating multifunctional beauty-from-within formulas targeting cellular senescence.
