Custom Top Rated Plant Based Protein Powder Factories & Factory

Our Non-GMO Identity Preservation (IP) system initiates at agricultural origin through contracted agronomic cooperatives utilizing certified Non-GMO seed stock. We maintain rigid physical segregation across seed reception, dry pre-cleaning, aqueous extraction, and spray drying lines. Each incoming raw botanical batch undergoes dual-target Real-Time Polymerase Chain Reaction (RT-PCR) testing targeting the 35S promoter and NOS terminator sequences. Furthermore, our entire supply pipeline complies with stringent European Union regulations (EC) No 1829/2003 and 1830/2003, with full analytical verification included in your regulatory lot package.

Beany and grassy off-flavors stem primarily from lipid oxidation catalyzed by endogenous lipoxygenases, producing volatile hexanals and octenols. Xi'an Le-Nutra employs a tripartite mitigation sequence: First, high-temperature brief-duration thermal deactivation of lipoxygenase before cellular disruption. Second, multi-stage counter-current washing at precise isoelectric points to strip volatile hydrophobic flavor precursors. Third, our proprietary post-extraction vacuum flash deodorization and targeted exo-peptidase digestion eliminate terminal hydrophobic amino acids responsible for perceived astringency. The resulting protein isolate exhibits sensory neutrality, allowing significant reductions in flavor masking agents in finished sports beverage powders.

For catalog-standard vegetal protein isolates (e.g., 80% and 85% pea and rice protein powders), our minimum order quantity starts at 25 kg (fiber drum packaging), with standard inventory dispatched within 3 to 5 business days from our Xi'an export hub. For custom-engineered specifications—such as tailor-made enzymatic hydrolysis profiles, specific D90 mesh sizes (from 80 to 300 mesh), customized instantization, or proprietary multi-protein blends—our minimum production campaign is typically 500 kg to 1,000 kg. We provide fully documented 100g to 1kg pilot evaluation samples accompanied by comprehensive batch Certificates of Analysis (COA) to support pilot bench trials and regulatory vetting prior to commercial production commitments.

Heavy metal bio-accumulation represents one of the most critical hazards in agrarian protein extraction. Our QC laboratory operates high-sensitivity Inductively Coupled Plasma Mass Spectrometry (ICP-MS, Agilent 7800 series) with detection limits in parts-per-billion (ppb). We enforce rigorous specifications: Lead (Pb) < 0.2 ppm, Arsenic (As) < 0.1 ppm, Cadmium (Cd) < 0.1 ppm, and Mercury (Hg) < 0.02 ppm. These internal controls ensure that even at maximum daily recommended dietary dosages of 30g to 60g of protein powder, the finished consumer formulation comfortably conforms to California Safe Drinking Water and Toxic Enforcement Act (Prop 65) Maximum Allowable Dose Levels (MADL) without requiring warning labels.

Yes. Automated vertical form-fill-seal (VFFS) and sachet packing machinery require powders with consistent bulk density, high flowability, and minimal dusting. We utilize laser diffraction particle sizing (Malvern Mastersizer 3000) to calibrate particle size distribution curves. Our fluid-bed agglomeration line can adjust bulk density across a range of 0.35 g/mL to 0.65 g/mL while drastically reducing static dusting. Additionally, our automated dual-shaft paddle dry blenders provide high homogeneity coefficient of variation (CV < 3%) for complex active premixes containing protein bases, digestive enzymes, vitamins, and standardized botanical extracts.

We supply a comprehensive Quality Vendor Qualification Dossier within 48 hours of formal procurement engagement.
