High-purity ingredients optimized for industrial applications, food production, and functional enhancement.
The global demand for high-quality gluten powder (Vital Wheat Gluten) and soy protein isolates is undergoing a fundamental structural transition. Driven by macro-demographic shifts, clean-label clean-ingredient compliance, and the explosive integration of plant proteins in food science, purchasing directors must look past basic trading structures to understand full circular extraction dynamics.
Xinrui Group, standing at the forefront of agricultural industrialization since 2003, bridges the gap between raw agricultural supply and high-precision protein texturizing. Crucial to this optimization is the deployment of imported tri-canter separation technologies. This physical process cleanly fractions wheat into Vital Wheat Gluten, Starch A, and Starch B without structural heat deformation, maintaining the native viscoelastic properties necessary for baking and meat analogs.
Native Vital Wheat Gluten (VWG) forms complex protein networks containing gliadins and glutenins. Gliadins offer extensibility while glutenins ensure elasticity, essential for gas retention in high-speed industrial baking lines.
Isolated Soy Protein (ISP) varieties, such as our 9007B-C and 9001BW, exhibit high water absorption and fat-binding rates, forming stable emulsion states vital for processed meat products and plant-based alternatives.
Nothing is wasted. Out of our 500,000-ton annual wheat grind, pentosans and Starch B fractions are directly routed into high-efficiency biorefineries to produce superior-grade ethyl alcohol, reducing the carbon footprint per ton of gluten powder.
Founded in 2007, Guanxian Xinrui Industrial Co., Ltd. (formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd) operates as the industrial backbone of our wheat processing cluster. With registered capital of 100 million Yuan and processing capacities exceeding 500,000 tons of wheat flour annually, the facility produces premium vital wheat gluten, wheat starch A, and wheat starch B.
Through our trade and export division, Guanxian Ruichang Trading Co., Ltd. (established in 2011), over 70% of our group company's production capacity reaches overseas food manufacturers. We deliver direct factory-to-port supply chain security, removing intermediate trading markups.
Unlike standard hydro-cyclone processes that compromise gluten protein chains, our tri-canter separation methodology applies controlled centrifugal force fields. This separates gluten and starch fractions with minimal water consumption and zero chemical modifications. The result is a clean-label gluten powder with a guaranteed 82% protein content (dry basis) and high hydration capacity (280-320%).
Established in 2014 with 120 million Yuan in registered capital, Shandong Kawah Oils Co., Ltd. is a leading provincial enterprise processing 180,000 tons of NON-GMO soybeans per year. Operating in complete isolation from genetically modified materials, Kawah Oils processes domestic raw soybeans into high-value derivatives step-by-step: Non-GMO soybean oil, low-temperature food grade soybean meal, isolated soy protein, and dietary fiber.
By employing spray drying towers engineered by DACHUANYUAN—featuring one of China’s largest single-line processing capacities—we guarantee uniform powder particle size distribution, resulting in excellent dispersion qualities across all batches.
How our plant proteins optimize yield, texture, and nutritional profiles across key industrial applications.
Vital wheat gluten acts as a natural structural enhancer. In low-protein flours, adding 1-3% gluten powder strengthens the gluten matrix, increasing dough tolerance, improving loaf volume, and extending shelf life.
Leveraging both Vital Wheat Gluten and Isolated Soy Protein (such as our 9001BW or 9007B-C) enables manufacturers to mimic animal muscle fibers. Under heat and shear forces, these proteins crosslink to form realistic textures.
| Protein Matrix | Protein Content (Dry Basis) | Water Binding Capacity | Primary Functional Role | Key Applications |
|---|---|---|---|---|
| Vital Wheat Gluten (VWG-P) | ≥ 82.0% | 1 : 2.5 - 3.0 | Viscoelastic network building, gas retention | Bakery, noodles, mock meats, pet treats |
| Isolated Soy Protein (ISP-9000 Series) | ≥ 90.0% | 1 : 5.0 - 6.0 | High emulsification, water/fat immobilization | Emulsified sausages, vegetarian meals, beverages |
| Functional Soy Concentrate (SPC) | ≥ 70.0% | 1 : 4.0 - 5.0 | Gelling, water absorption, structural retention | Meat products, processing adjuncts, feed formulations |
| Soy Dietary Fiber (SDF) | ≥ 18.0% (TDF ≥ 65%) | 1 : 8.0 - 10.0 | High moisture management, structural integrity | Bakery fiber enrichment, yield maximization |
Xinrui Group’s manufacturing site features integrated district heating, gas supply, and municipal waste-to-energy cogeneration systems. This circular model ensures that energy outputs from starch and ethanol processing loop directly back into our spray towers.
This closed circular system reduces electricity and thermal dependencies on external utilities, offering a resilient supply chain that remains unaffected by energy price spikes or industrial electricity limits. This guarantees secure, uninterrupted production for our global buyers.
Every batch is audited. We secure and retain international food safety standards for seamless customs clearance and formulation safety.
Transparency in manufacturing. Explore our advanced processing lines, quality control hubs, and packaging setups.

We are a group company named Xinrui Group integrating manufacturing and exporting. Our production ecosystem includes:
1. Shandong Kawah Oils Co., Ltd.: The manufacturer of soy protein isolate, producing 50,000 tons per year.
2. Guanxian Xinrui Industrial Co., Ltd. (formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd): The manufacturer of vital wheat gluten, producing 30,000 tons of gluten powder per year.
3. Guanxian Ruichang Trading Co., Ltd.: The specialized export entity managing international logistics, compliance, and custom clearances directly from the factory.
Our facilities comply with strict international regulatory standards. We hold active certifications for: HACCP, ISO9001, ISO22000, BRC (Global Standard for Food Safety), HALAL, KOSHER, and IP-NON GMO. Other compliance documents, third-party SGS analysis reports, and sanitary certificates are available upon request.
Our Vital Wheat Gluten (VWG-P/VWG-PS) features a water-binding ratio of 1:2.5 to 1:3.0. For Isolated Soy Proteins, the ratio ranges from 1:5.0 to 1:6.0 depending on the type selected. For instance, the 9007B-C Meat & Emulsion Type is optimized for high water immobilization under heat processing.
Shandong Kawah Oils operates utilizing IP (Identity Preservation) protocols. We source raw soybeans from registered domestic Non-GMO farming bases. Our processing lines are physically isolated from GMO grains, with rapid PCR testing performed on every inbound raw batch and outbound protein shipment.
Yes, our beverage and dispersion type isolates (9030/9032) are specifically processed to maintain low viscosity and high solubility under neutral pH. This avoids settling or sandy textures in protein-fortified milk, meal replacements, and dry-blend beverages.
From emulsions and dispersion types to vital wheat gluten pellets for feed systems.
