Vital Wheat Gluten (VWG), a natural, insoluble functional protein derived from the endosperm of the wheat grain (Triticum aestivum), constitutes the primary structural network of gluten-containing food formulations. Composed predominantly of two macro-proteins—Gliadin (which provides extensibility and viscosity) and Glutenin (which imparts elasticity and cohesive strength)—vital wheat gluten acts as an irreplaceable functional backbone in the commercial bakery, processed meat, and aquafeed industries.
As a global B2B supplier, our factory processes high-grade domestic wheat under strict ISO and BRC protocols, delivering gluten powders (VWG-P) and gluten pellets (VWG-PS) that meet the rigorous technical baselines demanded by multinational food brands.
Our state-of-the-art wet extraction system ensures optimal preservation of protein vitality by separating gluten from starches at low temperatures.
We leverage imported, clean, and fully-closed tri-canter separation machinery to divide the wheat flour slurry into high-purity Wheat Gluten, Starch A, Starch B, and soluble pentosans. This maximizes raw material utilization.
To prevent denaturation of the protein networks, wet gluten is processed via rapid low-temperature flash drying. This maintains the maximum water absorption index (150-180%) and viscoelastic functionality.
Starch B and extracted pentosans are instantly funneled into high-grade industrial ethanol fermentation and nutritional animal feeds, achieving a zero-waste, eco-friendly manufacturing cycle.
| Functional Parameter | Vital Wheat Gluten Powder (VWG-P) | Wheat Gluten Pellets (VWG-PS) | Industrial Applications |
|---|---|---|---|
| Protein Content (Dry Basis) | ≥ 75.0% - 82.0% | ≥ 72.0% - 78.0% | Dough conditioning, meat binding, aquafeed structural density. |
| Moisture Content | ≤ 10.0% | ≤ 11.5% | Optimized for long-term dry bulk storage and silo transportation. |
| Water Absorption Rate | 150% - 200% | 140% - 170% | Extends shelf life by retaining moisture inside starches. |
| Ash Content | ≤ 1.0% | ≤ 1.5% | Indicates raw material purity and fine filter extraction. |
Founded in May 2003, Xinrui Group spans over 1,000 mu of advanced industrial facilities. The group represents a circular economic powerhouse. Our subsidiary, Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd), established in 2007 with a registered capital of 100 million Yuan, spearheads our wheat deep-processing division, processing over 500,000 tons of wheat flour annually.
Complementing this, Shandong Kawah Oils Co., Ltd. (established in 2014, capital 120 million Yuan) processes 180,000 tons of non-GMO soybeans annually, utilizing state-of-the-art Dachuanyuan spray drying towers to manufacture world-class isolated soy protein and soy dietary fibers. Through Guanxian Ruichang Trading Co., Ltd., we unify factory production and direct trade, exporting over 70% of our production capacity directly to global markets.
In North American and European industrial bakeries, wheat gluten is added to low-protein flour to increase the strength of dough mixtures. This improves loaf volume, crumb structure, and gas retention capacity in high-speed automated production lines.
With the rise of vegan and vegetarian diets, gluten provides the fibrous, chewable texture that mimics animal muscle meat. Combined with our *Isolated Soy Protein*, it creates structurally sound vegetarian patties, nuggets, and sausages.
In aquaculture (especially salmon and shrimp feed), our vital wheat gluten pellets (VWG-PS) serve as a high-density, highly digestible protein source. It acts as a natural binder, ensuring the pellets remain intact in water without dissolving prematurely.
Our production facilities benefit from localized integration. Xinrui Group owns its cogeneration power plants, providing dedicated urban heating, gas supply, and processing power. This infrastructure insulates our wheat gluten and soy protein processing from energy price volatility.
Operating our own wheat and non-GMO soybean planting bases in close proximity to the factories ensures consistent grain inputs and strict traceabilty. From raw seed to final packed powder, every processing step is controlled internally, ensuring reliability during global logistics bottlenecks.
Investing in R&D to meet the global shift towards high-protein, clean-label raw materials.
By blending wheat gluten with our soy protein isolate, we are developing functional hybrids optimized for extrusion. These are tailored to the viscosity and chewiness profiles demanded by modern plant-based meat manufacturers.
To support global factory health standards, our production lines are upgrading to micro-pelletized wheat gluten. This form reduces airborne dust during bulk bag emptying and pneumatic transfer, improving safety in food plants.
We conform to global food safety standards, audited annually by external certification bodies.
