Vital Wheat Gluten (VWG), also known as wheat gluten or active wheat protein, is a natural, highly cohesive plant-based protein derived from the endosperm of premium wheat (Triticum aestivum). Comprising approximately 75% to 82% protein on a dry basis, vital wheat gluten is distinguished by its unique viscoelastic profile. The molecular structure of gluten is composed of two primary storage protein fractions: gliadins and glutenins.
Gliadins are monomeric proteins characterized by a molecular weight range of 30,000 to 80,000 Da. They function primarily as plasticizers within the protein matrix, imparting extensibility and viscosity. Glutenins, conversely, exist as massive polymeric networks linked by intermolecular disulfide bonds, with molecular weights exceeding millions of Daltons. These polymeric networks provide the vital gluten structure with its characteristic elasticity and cohesive strength. Upon hydration, these fractions form a three-dimensional thermosetting network capable of entrapping gas, water, and lipids, making it an indispensable functional component in industrial baking, milling, plant-based analog manufacturing, and specialized animal feed formulations.
Strategically situated in Shandong, the agricultural heartland of China, Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd.) operates a state-of-the-art facility optimized under Industry 4.0 standards. Established in 2007 with a registered capital of 100 million Yuan, our plant has evolved into one of the largest and most technologically advanced integrated bio-refineries in the region, processing 500,000 tons of wheat flour annually.
Unlike conventional separation techniques that can degrade protein structures, our facility utilizes imported European Tri-Canter separation systems. This closed-loop process uses centrifugal force to divide the wheat slurry into high-purity vital wheat gluten, Grade-A wheat starch, and Grade-B wheat starch. By maintaining strict control over temperature and shear forces, we prevent protein denaturation, preserving the natural viscoelasticity of the gluten molecules.
Operating as a circular economy, we utilize every byproduct of our manufacturing line. Pentosans and Grade-B starch are channeled directly into our integrated fermentation plant to produce high-grade ethanol and animal feed. Cogeneration facilities within the Xinrui Group supply steam and electricity, lowering carbon emissions and production costs. This vertical integration ensures supply chain resilience, decoupling our pricing from localized energy fluctuations.
Furthermore, our sister company, Shandong Kawah Oils Co., Ltd. (established in 2014 with 120 million Yuan registered capital), processes 180,000 tons of soybeans annually, extracting high-purity, IP-Non-GMO soybean protein isolates, dietary fibers, and soybean oil. By employing China’s largest single-line spray drying tower, manufactured by DACHUANYUAN, the group ensures consistent output quality and large-scale manufacturing capability.
As a key supplier to international brands, we provide custom vital wheat gluten configurations tailored to specific industrial sectors:
For industrial milling groups, our gluten serves as a natural flour improver. When added to low-protein flour, it increases dough water absorption, improves mixing tolerance, and enhances gas retention during yeast fermentation, resulting in optimized loaf volume and uniform crumb cell structure.
In meat alternatives, the texturizing capabilities of our gluten are critical. Under high-moisture extrusion, it forms cross-linked disulfide networks that simulate the fibrous texture of beef, pork, and chicken. It acts as an emulsion stabilizer, preventing fat separation during thermal processing.
In aquaculture feed, our wheat gluten serves as a high-performance binder, improving pellet durability and water stability to prevent nutrient leaching. For pet foods, its high digestibility (>90%) and balanced amino acid profile make it an excellent choice for premium formulations.

Quality Control & R&D Laboratory
Large-scale purchasing managers operate in a complex environment defined by fluctuating spot pricing, shipping container logistics, and strict ingredient specifications. At Guanxian Xinrui Industrial, we minimize these pain points through our export and logistics subsidiary, Guanxian Ruichang Trading Co., Ltd. (founded in 2011, 6 million Yuan registered capital). Direct factory export represents over 70% of our capacity, ensuring streamlined communication and reduced middleman margins.
We offer two primary product physical states tailored to transport and processing requirements:
To support overseas logistics, we offer diverse packaging configurations (25kg multi-wall paper bags, 1,000kg bulk super-sacks, and custom pneumatic bulk truck loading) with dedicated moisture barrier liners to preserve functionality over long ocean transit routes.
To ensure seamless customs clearance and compliance with international food regulations, our manufacturing sites are audited annually against international standards. Our quality assurance program covers pesticide residue screening, heavy metal limits, microbiological testing, and PCR analysis to verify non-GMO status.
Our raw material tracing system tracks wheat back to our cooperative agricultural cultivation bases. This vertical control ensures full transparency from seed selection to final packaging, providing our customers with a highly secure and auditable supply chain.
Looking toward 2030, our R&D roadmap focuses on three main developments:
We are an integrated group company named Xinrui Group that combines manufacturing and exporting. Our soy protein isolate is manufactured by Shandong Kawah Oils Co., Ltd., which produces 50,000 tons of isolated soy protein annually. Our wheat gluten is manufactured by Guanxian Xinrui Industrial Co., Ltd. (formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd), which produces 30,000 tons of vital wheat gluten annually. Our export and international trade operations are managed by Guanxian Ruichang Trading Co., Ltd.
We hold HACCP, ISO9001, ISO22000, BRCGS, HALAL, KOSHER, IP-NON GMO, and SGS certifications. We can also provide other specialized third-party analysis reports or compliance certificates upon request.
Our Vital Wheat Gluten maintains a water absorption capacity between 150% and 200% under standard testing. This is due to our low-temperature drying process, which preserves the structural integrity of the glutenin and gliadin proteins.
Our soybean processing plant, Shandong Kawah Oils Co., Ltd., uses exclusively non-GMO soybeans and maintains an Identity Preservation (IP) system verified by third-party auditors. The facility is physically separated from any GMO-handling processes to prevent cross-contamination.
Our pellets increase bulk density compared to fine powder, allowing for higher weight loading per container. They also improve flowability in discharge systems and significantly reduce airborne dust in industrial environments.
Yes, we provide 25kg multi-layer valve paper bags, 1000kg bulk container jumbo bags, and customized private-label packaging to meet specific warehouse and handling requirements.
Complete your supply chain with our specialized functional protein and ethanol products, designed for high performance across diverse applications.
