The global shift toward plant-based proteins is no longer merely a consumer lifestyle trend; it represents a fundamental re-engineering of the global food architecture. Industrial buyers, food formulators, and pharmaceutical procurement directors face increasing market demand for clean-label, allergen-free, and high-PDCAAS (Protein Digestibility-Corrected Amino Acid Score) plant protein sources.
As a premier wholesale plant-based protein supplier and exporter, we bridging the gap between raw botanical biomass and ready-to-formulate functional isolates. By utilizing low-temperature aqueous extraction, enzymatic hydrolysis, and flash drying technology, our plant proteins retain structural integrity, native solubility, and superior gelation capabilities required for complex food matrixes.
In accordance with Google's Search Quality Rater Guidelines, our manufacturing process is backed by rigorous empirical data and verifiable credentials. Every batch of plant protein exported from our state-of-the-art facilities undergoes comprehensive analytical testing via High-Performance Liquid Chromatography (HPLC) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS).
We ensure zero heavy-metal contamination, strict pesticide residue limits compliant with EU Regulation (EC) No 396/2005, and guaranteed non-GMO origins. Whether sourcing isolate powders for human nutrition, active phytosterols for cosmetics, or bioavailable protein premixes for aquaculture, our technical documentation delivers absolute supply-chain certainty.
Xi'an Herbpro Biotech Co., Ltd. is the leading manufacturer in research, development, production, sale and service of Cosmetic Ingredients, healthcare ingredients, fruits & vegetables powder, Food Additives, as well as Chinese medicine raw material. We insist on producing high quality, green products for human health. Building mutually beneficial and win-win partnership as our development strategy.
We have 2 factories with area about 40,000 square meters totally, and located in Xi'an, Shaanxi, China with convenient transportation. The whole process of production in accordance with GMP standard of the state to adequately ensure the safety, efficacy and stability of our products.
We also welcome OEM and ODM orders. We excel at customizing powders, gummies, and capsule encapsulation services—whether selecting standard catalog products or formulating custom plant protein solutions tailored to specific commercial specifications.
Understanding the functional behavior of botanical proteins requires evaluating their amino acid profiles, nitrogen solubility index (NSI), and thermal denaturation kinetics. Below is an engineering overview of our raw plant protein isolates compared across core industrial metrics.
| Protein Source Material | Protein Purity (%) | PDCAAS Score | Solubility Index (pH 6.5 - 7.5) | Primary Application Focus |
|---|---|---|---|---|
| Yellow Pea Protein Isolate | 80.0% – 85.0% | 0.91 – 0.93 | > 88% High Instantization | Sports Nutrition, RTD Shakes, Meat Analogs |
| Non-GMO Soy Isolate | 90.0% – 92.0% | 1.00 | > 92% Dynamic Emulsification | Emulsified Meats, Bakery, Dairy Alternatives |
| Organic Microalgae (Chlorella) | 60.0% – 65.0% | 0.86 – 0.89 | Dispersible Powder Form | Nutraceuticals, Superfood Blends, Clinical Feed |
| Hydrolyzed Plant Peptides | 85.0% – 90.0% | 0.95 – 0.98 | 100% Fully Water Soluble | Cosmeceuticals, Rapid Bio-Absorption Drinks |
| Enzyme-Treated Feed Proteins | 65.0% – 75.0% | 0.82 – 0.85 | Medium Gelation / Feed Attractant | Aquaculture, Poultry Premixes, Pet Food |
We deploy ultra-modern wet extraction processes to separate plant proteins from starches and dietary fibers at the molecular level. By carefully tuning pH levels to the isoelectric point of specific plant globulins, we achieve purity exceeding 90% without degrading essential branched-chain amino acids (BCAAs).
Natural plant proteins often carry off-notes such as earthy or beany organoleptic profiles. Our proprietary enzymatic cleavage masks off-flavors while breaking macro-proteins into bioavailable micro-peptides, making them ideal for neutral-tasting beverage systems and cosmetic formulations.
For high-moisture meat extrusion (HMMA), texture integrity is paramount. Our isolated proteins feature engineered gel strength and water-binding capacity (up to 1:5 ratio), providing authentic fibrous structures in plant-based burger patties, sausages, and seafood alternatives.
Our operational strategic advantage originates in our localized agricultural supply network across Shaanxi, Heilongjiang, and Inner Mongolia. By securing direct-from-farm raw crops—including Non-GMO soybeans, non-GMO golden peas, and traditional botanical roots like Astragalus—we maintain end-to-end traceabilities that eliminate market price volatility for international enterprise clients.
Operating out of our two expansive manufacturing plants in Xi'an covering 40,000 square meters, we integrate centralized processing line automations that reduce per-ton production cost while maintaining zero batch-to-batch variation.
Navigating cross-border botanical and protein import laws requires exhaustive regulatory documentation. As a dedicated bulk exporter, Xi'an Herbpro Biotech equips clients with turn-key compliance paperwork:
Formulate premium protein powders, RTD protein shakes, meal replacement bars, and dietary supplements. Our high-solubility instantized isolates blend smoothly into liquids without grittiness or chalky texture, accepting flavor profiles naturally.
Achieve fibrous textures, structural water holding, and authentic mouthfeel in plant-based meats, cheeses, and dairy-free yogurt formulations. Superior thermal setting properties guarantee consistency across pasteurization and cooking.
Replace costly fishmeal and animal-derived proteins in livestock, poultry, and aquaculture nutrition. Our highly digestible feed-grade proteins enhance growth rates, improve feed conversion ratios (FCR), and optimize gut health.
Consumer preferences are rapidly shifting away from major allergens (such as wheat gluten and traditional dairy) toward naturally hypo-allergenic botanical sources like yellow pea, mung bean, and microalgae proteins. Clean-label mandates require manufacturers to eliminate chemical solvents during extraction—a principle built directly into our aqueous processing facility standards.
Sustainability metrics are driving the adoption of circular bio-economy ingredients. Microalgae proteins like Chlorella and Spirulina provide hyper-concentrated amino acid profiles while consuming minimal land and water resources. Xi'an Herbpro Biotech continues to lead in cultivating and micro-milling bio-pure algal isolates for technical applications.
Our standard MOQ for wholesale raw protein isolate powders starts at 25kg (1 full drum/bag). For custom OEM/ODM formulations, customized mesh sizes, or specialized spray-drying packaging, MOQs generally start at 500kg depending on ingredient specifications.
Every batch includes a comprehensive Certificate of Analysis (COA) detailing active protein percentage, moisture content, heavy metal panel (Pb, As, Cd, Hg), microbiological counts (E. coli, Salmonella, Mold/Yeast), and pesticide residue screens aligned with EU/US regulations.
We employ enzymatic hydrolysis to break down long-chain proteins into highly soluble peptides. Combined with physical agglomeration and micro-encapsulation, our plant proteins yield zero grit and minimal flavor interference in liquid systems.
Yes. Xi'an Herbpro Biotech holds EU Organic and USDA Organic certificates alongside Halal, Kosher, FDA registration, ISO 9001, and HACCP certifications, allowing seamless export into international markets.
We provide end-to-end custom manufacturing including custom particle micronization (80 to 300 mesh), custom protein ratio blending, vitamin premixing, private label packaging, tablet pressing, and capsule encapsulation.
Standard catalog inventory dispatches within 3-5 business days. Air freight delivery generally takes 7-10 business days globally, while sea freight ranges from 18 to 35 days depending on the destination port.
