Direct supply from state-of-the-art facilities featuring advanced multi-stage processing, strict quality metrics, and integrated global logistics.
Established in May 2003,
Founded in 2007 (formerly Guanxian Ruixiang Biotechnology) with registered capital of 100 million Yuan. The facility annually processes 500,000 tons of wheat flour, extracting vital wheat gluten, wheat starch A, and wheat starch B. The downstream processing feeds into alcohol and animal feed, showcasing our advanced, closed-loop circular economy.
Established in 2014 with 120 million Yuan registered capital, this provincial leading enterprise processes 180,000 tons of domestic NON-GMO soybeans annually. Extracting soy oil, low-temperature meal, isolated soy protein (ISP), and dietary fiber. Features China's largest single spray drying tower production line, imported from DACHUANYUAN.
Formed in 2011 with 6 million Yuan registered capital to operate as the group's global trading engine. Directly exporting isolated soy protein, wheat gluten, soluble dietary fiber, vermicelli, and ethanol to international markets. Overseas exports represent over 70% of the factory's production capacity.
By controlling the raw material supply chain directly through our integrated WHEAT AND NON-GMO SOYBEAN PLANTING BASES, Xinrui Group guarantees full farm-to-table traceability. Our manufacturing processes utilize automated, clean, and enclosed lines to avoid cross-contamination. Our technical systems ensure that vital nutrients are retained while sub-components, such as Starch B and pentosan, are repurposed efficiently for bio-ethanol and high-protein feed additives.
Vital wheat gluten (VWG) is the natural, insoluble protein fraction extracted from high-quality wheat. Renowned for its unique viscoelastic properties, VWG acts as a cohesive binder, texturizer, and protein fortifier. In the global B2B food sector, the demand for high-purity wheat gluten is rising, driven by three major macro-trends:
As consumers scrutinize ingredient decks, developers are replacing synthetic chemical stabilizers and gums. Vital wheat gluten serves as a completely natural, allergen-declaration-standard component that improves crumb structure, water retention, and shelf-life in industrial baking.
VWG's elastic fiber matrix mimics animal muscle tissue under high shear. It is widely used in high-moisture extrusion (HMEC) alongside isolated soy protein (ISP) to manufacture texturized vegetable protein (TVP) products, vegan steaks, and premium sausages.
In premium aquaculture feeds (such as shrimp, salmon, and eel diets), VWG acts as a nutrient-dense, highly digestible binder. It ensures high water stability of the pellets, preventing nutrient leaching and minimizing water pollution in commercial farms.
Historically, the wheat gluten extraction process suffered from thermal denaturing during flash drying, which ruined the vitality (elasticity) of the gluten. Guanxian Xinrui Industrial solved this by implementing an ultra-low-temperature pneumatic flash drying system. By keeping the drying environment highly controlled, we preserve the molecular integrity of the gliadin and glutenin proteins, ensuring rapid hydration and excellent tensile strength when reconstituted by food formulators worldwide.
The core extraction process at Guanxian Xinrui Industrial utilizes state-of-the-art wet-separation systems. Rather than relying on standard Martin-process washing, which consumes vast volumes of water and risks protein denaturation, we employ imported high-performance
Wheat flour is continuously mixed with purified water at precise temperatures to fully hydrate the proteins, encouraging the formation of an extensive disulfide-bonded gluten matrix.
The hydrated slurry enters the tri-canter centrifuge. Under high g-force, the mixture is separated cleanly into three distinct streams: a light liquid phase (highly concentrated gluten protein), a heavy solid phase (Starch A), and a middle liquid phase (Starch B + pentosan).
The isolated gluten fraction undergoes multi-stage, counter-current washing to remove remaining free starches, increasing dry-basis protein content to ≥ 75-82%.
The purified wet gluten is dispersed into a high-speed, hot airstream. Rapid evaporation occurs in milliseconds, ensuring that the product temperature never exceeds the denaturing point. This step preserves the vitality of the gluten.

Through our subsidiary,
Our facility houses China's largest single spray drying tower, engineered by DACHUANYUAN. This massive system allows for uniform hot-air distribution, producing soy protein isolate particles with optimal hydration rates, dispersibility, and emulsification capabilities. Whether formulating for high-viscosity meat emulsions or instant-dispersing protein beverages, our functional soy isolates deliver exceptional stability under challenging processing temperatures.
By using locally sourced, identity-preserved (IP) Non-GMO soybean crops, we guarantee clean supply chains compliant with European Union and North American food-label regulations.
Our combined plant protein portfolio (Vital Wheat Gluten, Isolated Soy Protein, Soy Dietary Fiber, and Wheat Starch) is designed for high-performance industrial applications:
Millers add our Vital Wheat Gluten to correct weak wheat crops, raising weak flours to patent-grade bread flour specifications. In bakeries, it improves gas retention in doughs, leading to higher loaf volume, softer crumb structures, and better resilience under mechanical slicing.
Using Isolated Soy Protein (Meat & Emulsion type 9007B-A / 9001BW), sausage and burger manufacturers can stabilize oil-in-water emulsions, preventing fat separation during thermal cooking and boosting the overall protein content of the finished products.
Our VWG-PS Wheat Gluten Pellets are formulated specifically for high-extrusion fish feeds and dry kibble. In fish diets, the pellets act as a non-water-soluble binder, maintaining pellet shape and reducing fines in pond water.
Xinrui Group operates a zero-waste manufacturing site. Our cogeneration plant supplies green steam to our wheat milling lines and soybean extraction columns. Water used in wheat starch separation is recovered, treated, and routed to generate industrial grade alcohols (95% & 96% Superior Grade Ethanol). The residual pentosan and low-density starch fractions are dried into high-nutrient feeds for surrounding agricultural partners.
We manufacture four major ingredient lines under strict pharmaceutical-grade GMP conditions. Check our specialized portfolio catalog below:
We support various packaging sizes ranging from 25kg multi-wall paper bags with PE-liners to 1,000kg bulk jumbo super-sacks, shipping directly from our port warehouses.
