OEM Healthiest Plant Based Protein Manufacturer & Factory

In modern scientific procurement, the "healthiest" plant protein is defined by three strict biochemical markers: 1) A balanced essential amino acid profile achieving a PDCAAS of ~1.0; 2) The systematic absence of anti-nutritional factors (ANFs) such as phytates, lectins, and trypsin inhibitors; and 3) Hypoallergenicity achieved through mechanical and enzymatic separation rather than aggressive chemical solvents (like hexane or heavy acid-precipitation washes).

Traditional isolate production relies heavily on alkaline solubilization followed by isoelectric acid precipitation. This often denatures essential amino acids, damages solubility, and creates an unpalatable gritty mouthfeel. Le-Nutra uses targeted biocatalytic proteases at controlled pH and moderate temperatures to cleave high-molecular-weight globulins into specific bioactive oligopeptides (<2000 Da). This dramatically improves intestinal uptake, grants complete clarity in solution, and ensures rapid cellular bioavailability.

Standard catalog ingredients (such as Hydrolyzed Rice Protein, Hydrolyzed Pea Protein, and Allantoin) carry an MOQ as low as 25 kg for pilot and formulation testing. For bespoke OEM/ODM custom specifications (custom molecular weight cutoffs, custom mesh size, debittering parameters, or specialized premixes), the typical MOQ is 500 kg to 1,000 kg. Pilot test runs typically dispatch within 3–5 working days, while bulk multi-ton orders ship within 14–21 business days.

Yes. Our R&D application laboratory specializes in precision membrane ultra-filtration (MWCO). For hair care formulations requiring penetration into the hair cortex, we produce short-chain hydrolysates in the 300 to 1,000 Da window. For cosmetic barrier-forming applications or food-grade emulsions, we can isolate larger fractions ranging from 2,000 to 5,000 Da. All specifications are confirmed by molecular weight distribution reports via Size Exclusion HPLC (SEC-HPLC).

Our 60,000 m² manufacturing plant operates under audited ISO9001, ISO22000, and cGMP compliance frameworks. Our supply chain has achieved verified EcoVadis Corporate Social Responsibility ratings and maintains Kosher and Halal production certifications. Every exported batch undergoes comprehensive third-party testing (SGS, Eurofins) for heavy metals, pesticide residues, and microbial bioburdens.

Beany off-flavors stem from lipid oxidation and lipoxygenase enzyme activity that produces hexanal and other volatile aldehydes. Le-Nutra implements a dual flash thermal-deactivation step followed by proprietary vacuum deaeration and activated carbon/resin filtration. This neutralizes odoriferous volatile compounds at the molecular level, providing formulators with an ultra-neutral sensory base that requires minimal flavor masking.

We provide a complete regulatory packet: Certificate of Analysis (COA) with actual tested quantitative values, 16-section Safety Data Sheets (SDS/MSDS) compliant with REACH and OSHA, Technical Data Sheets (TDS), Flow Charts of Manufacturing, Statements of Non-GMO, BSE/TSE-Free certificates, Allergen declarations, and heavy metal & solvent residual compliance statements aligned with USP <467> and <2232>.

Through strategic backward integration, Xi'an Le-Nutra contracts directly with farming bases across primary agricultural regions in China. We maintain a permanent buffer inventory of raw feedstock and finished products within our 60,000 m² campus. We offer long-term annualized fixed-price procurement agreements (blanket orders with scheduled releases) to insulate global partners from spot-market commodity spikes.
