Direct from our 60,000 m² Xi'an manufacturing complex. Featuring controlled Dalton weight distributions, high active peptide assays, and documented batch-to-batch reproducibility for personal care and nutritional manufacturing.
The transition toward functional biocosmetics and clinical nutrition has revolutionized global demand for hydrolyzed proteins. Contemporary procurement executives and cosmetic chemists no longer view hydrolysates merely as bulk colloidal conditioners or generic nitrogen carriers. Instead, they demand highly defined, enzymatically targeted short-chain oligopeptides, dipeptides, and free amino acid matrices engineered for specific physiological interactions.
As a specialized hydrolyzed proteins exporter with over 14 years of dedicated peptide cleavage innovation, Xi'an Le-Nutra Ingredients Inc. bridges the critical gap between raw botanical isolates and bioactive performance. By transitioning away from harsh acid-hydrolysis regimens toward multi-enzyme biocatalytic cleaving, we safeguard natural amino acid chiral structures while eradicating toxic by-products such as 3-MCPD (3-monochloropropane-1,2-diol).
Global procurement teams face escalating regulatory scrutiny across the European Union (EU Regulation 1223/2009), the United States (FDA MoCRA), and the Asia-Pacific region (NMPA CSAR). Le-Nutra's comprehensive supply-chain transparency empowers Fortune 500 formulators, contract manufacturing organizations (CMOs), and independent indie beauty incubators to bypass downstream certification bottlenecks and secure verifiable, high-efficacy ingredient streams.

International raw material sourcing encounters systematic friction points that impair production schedules and undermine product stability. Discover how Le-Nutra mitigates risks across complex global supply corridors.
Uncontrolled chemical hydrolysis creates massive polydispersity indexes where macromolecules fail to penetrate hair cuticles, while excessive free amino acids cause stickiness. Le-Nutra employs enzymatic fractionation columns to deliver consistent, narrow molecular weight distributions batch after batch.
Thermal degradation of amino acids during traditional concentration produces bitter notes, sulphur by-products, and dark caramelization. Our multi-stage activated carbon adsorptive decolorization and gentle low-temperature thin-film vacuum evaporation guarantee faint-colored, odor-neutral hydrolysates.
Sudden regulatory audits frequently halt international shipments lacking traceable botanical provenance, heavy metal documentation, or non-animal verification. Le-Nutra pre-empts customs delays by issuing multi-jurisdictional dossier packages tailored directly to US, EU, and Asian cosmetic monographs.
Engineered protein hydrolysates offer multi-functional capabilities across cosmetics, cosmeceuticals, functional foods, and veterinary therapeutics. Here is how our specialized grades perform inside target matrices.
In high-performance hair care (shampoos, bonding serums, restructuring masks), molecular weight dictates efficacy. Hydrolyzed wheat, oat, and keratin peptides beneath 1,500 Da cross the outer cuticle scale boundary, forming ionic cross-links with native alpha-keratin. This restores tensile strength by up to 34% in chemically bleached tresses while higher molecular fractions (3,000+ Da) deposit a protective, lustrous elastomeric shield.
Hydrolyzed rice, soy, and spirulina peptides mirror the skin's endogenous amino acid composition (rich in serine, glycine, alanine, and pyrrolidone carboxylic acid precursors). These hygroscopic micro-peptides reinforce the intercellular lipid matrix, elevate trans-epidermal moisture retention (TEWL reduction), and stimulate cellular proliferation in stressed basal fibroblasts without triggering comedogenicity.
In sports recovery beverages and medical enteral formulas, intact vegetable isolates often trigger gastrointestinal distress and delayed gastric emptying. Le-Nutra's hydrolyzed pea and quinoa powders showcase low osmolality and rapid di- and tri-peptide transport via the intestinal PEPT1 transporter, speeding essential amino acid uptake into peripheral muscle beds by 40% compared to unhydrolyzed concentrates.
Our closed-loop industrial cleavage workflow is calibrated across every thermodynamic and enzymatic variable, safeguarding peptide integrity and eliminating batch variance.
Raw non-GMO grains, legumes, and marine sources undergo centrifugal lipid separation, aqueous extraction, and isoelectric precipitation to extract ultra-pure non-denatured protein bases (>85% protein content).
Dual-stage enzymatic cleavage utilizes specific food-grade proteases (alcalase, papain, neutrase, and flavourzyme) to selectively cleave peptide bonds at specific terminal amino acids, preserving bioactivity.
Enzymatically digested broths are routed through multi-stage ceramic and spiral polymeric ultrafiltration membranes with molecular cut-offs at 500 Da, 1,000 Da, and 3,000 Da to narrow peptide size classes.
Following nanofiltration desalting, the concentrate is spray-dried in sterile centrifugal drying towers with micro-inlet temperatures to prevent Maillard browning, yielding instantly dispersible powders.
Operating out of the High-Tech Industrial Development Zone in Xi'an, China, Xi'an Le-Nutra Ingredients Inc. has accumulated more than 14 years of specialized expertise in protein separation, bio-catalytic peptide cleavage, and high-purity botanical extraction. Our manufacturing operations meet the uncompromising audit criteria of multinational giants across Europe, North America, Japan, and Southeast Asia.
Our ingredients serve as benchmark raw materials in product pipelines connected to leaders such as BASF, DSM, Abbott, 3SBio, and Estée Lauder. With 6 multi-functional extraction trains, automated CIP (Clean-In-Place) sanitation cycles, and advanced HPLC, GC-MS, and ICP-MS testing suites, our facilities maintain strict lot-to-lot bio-equivalence and absolute chemical safety.
