Standardized functional ingredients engineered for cross-sector compatibility with hydrogenated and hydrolyzed peptide matrices.
Bridging the gap between raw native collagen macro-proteins and ultra-stable, highly absorbable low-molecular oligopeptides for medical nutrition, high-end cosmeceuticals, and functional delivery systems.
Native collagen is a massive triple-helix glycoprotein (approximately 300 kDa) that exhibits negligible gastrointestinal absorption and high thermal instability in aqueous solutions. Traditional hydrolysates, while broken into smaller chains, frequently retain residual unsaturated bonds, prone to oxidative degradation, yellowing, and off-note formation.
Hydrogenated and catalytic hydro-refined collagen peptides incorporate precision hydro-saturation following enzymatic cleavage. This saturation prevents downstream Maillard reaction cross-linking, terminates reactive free radicals, and locks the bioactive tripeptide chains (notably Gly-Pro-Hyp and Pro-Hyp) into an exceptionally stable, organoleptically neutral state.
Operating from our modern 60,000-square-meter facility in Xi'an, China, Xi'an Le-Nutra Ingredients Inc. integrates over 14 years of biochemical extraction expertise with six high-throughput multi-functional production lines. With an annual capacity of 3,000 metric tons, we engineer custom peptide cuts ranging from 500 Da to 3,000 Da.
Our infrastructure features multi-stage gradient ceramic membrane separation, continuous vacuum low-temperature concentration, closed-loop catalytic reaction chambers, and sterile Class D spray-drying towers, guaranteeing consistent lot-to-lot bio-activity, ultra-low ash content (≤1.0%), and complete organoleptic clarity.
Formulation scientists are transitioning from standard hydrolysates to stabilized bioactive oligopeptides. Below are the macro trends shaping formulation criteria worldwide.
Broad-spectrum molecular weight powders are being phased out in premium nutraceuticals. Global brands now demand tightly controlled Gaussian distributions where >80% of peptide fragments measure between 500 Da and 1,000 Da. This ensures rapid paracellular transport via PEPT1 intestinal transporters without relying on gastric enzyme pre-digestion.
Marine- and bovine-derived collagens traditionally suffer from sulfurous, fishy, or amine-like odors that require heavy masking agents. Hydro-saturated stabilization chemically eliminates volatile lipid-peroxide precursors. The resulting peptide dissolves 100% water-clear within 15 seconds, exhibiting neutral flavor at concentrations up to 12% w/v.
In high-moisture gummies and liquid core capsules, conventional collagen peptides cross-link with aldehydes, polyphenols, and sugars, creating insoluble rubbery matrixes. Custom hydrogenated peptides provide saturated terminal structures, completely preventing container degradation and preserving shelf-life dissolution rates across 36 months.

All batches carry transparent certification: ISO 9001, ISO 22000, FSSC 22000, cGMP compliant manufacturing, EcoVadis Corporate Social Responsibility, Halal, and Kosher certifications. Every shipment includes a verified Batch COA, Technical Data Sheet, and 16-section GHS Safety Data Sheet.
Direct supply lines connect our Xi'an production base to logistics hubs across Europe (Rotterdam, Hamburg), North America (Los Angeles, Chicago), and the Asia-Pacific region. Documentation matches regional import rules, covering FDA FSMA guidelines, EU Novel Food status, and EFSA hygiene compliance.
We work with brand owners and CDMO partners to adjust critical powder metrics: particle mesh sizes (from 80 to 200 mesh), bulk density (0.35 to 0.65 g/mL), customized molecular weight cuts, agglomerated instant grades, and tailored batch packaging (from 1 kg vacuum packs to 25 kg fiber drums).
How Le-Nutra's biochemical team is advancing collagen peptides from standard nutrition to target-guided bio-therapeutics.
Using proprietary protein-ligand modeling algorithms, our R&D team maps the secondary and tertiary folds of collagen chains. This enables tailored enzyme mixes that consistently cut exact Gly-Pro-Hyp and Pro-Hyp motifs, raising tripeptide purity from 3% to over 25% without relying on synthetic linkers.
Moving from traditional batch processing to continuous plug-flow hydro-reduction systems lowers operational energy use by 35% while tightening saturation levels across production runs. This closed loop minimizes oxidative degradation, delivering a stable shelf life of 36 months.
Our extraction lines feature continuous Near-Infrared (NIR) spectroscopic sensors that measure protein purity, moisture, and molecular distribution every 30 seconds. Out-of-spec batches are automatically flagged and rerouted, ensuring consistent lot-to-lot reliability.
Key answers addressing molecular weight verifications, regulatory documentation, and production customization.
Conventional hydrolyzed collagen is produced strictly via enzymatic hydrolysis or acid/alkali cleavage, leaving terminal unsaturated ends and residual peptide chains susceptible to oxidation, yellowing, and amine/sulfur odor generation. Hydrogenated and hydro-refined collagen peptides undergo an additional catalytic hydro-saturation process that saturates vulnerable bonds, eliminates odor-causing lipid peroxides, halts Maillard-type cross-linking in liquid formulations, and yields an ultra-stable, water-clear peptide matrix with a longer shelf life.
Through our multi-stage ceramic membrane ultrafiltration system, we tailor molecular distributions based on target applications: Ultra-Low Tripeptide Grades (500–800 Da, ideal for cosmeceuticals and instant transdermal serums), Standard Bioactive Nutrition Cuts (1,000–1,500 Da, for high-potency sports nutrition and functional beverages), and Balanced Structural Grades (2,000–3,000 Da, for compressed tablets and functional bars). Each batch is verified by GPC-HPLC against standardized molecular markers.
In high-density softgels and pectin/gelatin gummies, standard collagen hydrolysates cross-link with aldehydes, residual sugars, or reactive polyphenols, forming a rubbery pellicle that delays dissolution times beyond USP limits. Hydro-saturation stabilizes the free amine-terminal profiles, preventing these covalent links and preserving fast disintegration and stable release profiles throughout ambient storage.
Every commercial delivery includes a comprehensive qualification packet: Batch Certificate of Analysis (COA) specifying molecular distribution, peptide assay, heavy metals (ICP-MS), and microbiological limits; 16-section Safety Data Sheet (SDS) compliant with GHS and REACH; Allergen Statement; Non-GMO Declaration; BSE/TSE-Free Certificate; Flowchart of Manufacturing; and Facility Certifications (ISO 9001, ISO 22000, FSSC 22000, Halal, Kosher, EcoVadis).
Our 60,000 m² production facility in Xi'an runs six automated production lines producing roughly 3,000 metric tons per year. Standard specification orders typically ship within 7 to 10 business days from inventory reserves. For custom-tailored molecular weights, specific enzyme treatments, or custom bulk packaging, production runs take 2 to 3 weeks. Our standard MOQ starts at 25 kg (one standard fiber drum), with pilot-scale sample batches (100 g to 1 kg) available for R&D trials.
Due to extensive de-mineralization and uniform small chain lengths, our hydrogenated collagen peptides dissolve completely in cold water (≤15°C) without clumping. They remain stable in high-acid formulas (down to pH 2.8) and withstand UHT/HTST pasteurization (up to 138°C) without precipitate formation, hazing, or flavor changes, making them well-suited for RTD functional shots, seltzers, and clear protein beverages.
