Explore our diverse portfolio of high-purity isolated soy proteins, premium soy dietary fibers, and functional wheat proteins.
GUANXIAN XINRUI INDUSTRIAL CO., LTD. (formerly known as GUANXIAN RUIXIANG BIOTECHNOLOGY DEVELOPMENT CO., LTD) was established in 2007 with a registered capital of 100 million Yuan. Strategically operating as a powerhouse in agricultural deep processing, the company processes 500,000 tons of wheat flour annually. Utilizing raw wheat material, we manufacture premium Vital Wheat Gluten (pelleted and powder form), Wheat Starch A, and Wheat Starch B. The residual Starch B and pentosan are systematically funneled into manufacturing high-purity agricultural ethanol and superior animal feed, completing a sophisticated closed-loop circular economy industry chain.
Our wheat processing infrastructure features state-of-the-art tri-canter separation technology, imported from leading global manufacturers. Every step of our production line is fully automated, closed, and hygienically sealed, ensuring clean-in-place operations. Consequently, the output value, manufacturing equipment, technological capabilities, and product reliability are positioned at the absolute forefront of the national and international industry.
Why large-scale buyers choose pelleted vital wheat gluten over conventional powder for bulk logistics and industrial consistency.
Conventional Vital Wheat Gluten powder suffers from cohesive flow properties, bridging in storage silos, and generating hazard-prone dust. Pelleted Vital Wheat Gluten (VWG-PS) exhibits exceptional free-flowing characteristics, significantly reducing wear on mechanical conveying systems and eliminating dust explosion hazards.
By compressing high-vitality wheat gluten into dense pellets, bulk density is increased by up to 40%. This drastic volume reduction maximizes container fill rates, optimizes oceanic shipping logistics, and minimizes freight costs per metric ton, creating a highly cost-efficient procurement route.
In modern aquafeed and premium pet food formulations, protein retention and pellet water stability are crucial. Our VWG-PS retains its native viscoelastic properties. Upon processing, it forms a cohesive, resilient matrix that retains nutrients, preventing underwater leaching and enhancing target species uptake.
To streamline global B2B procurement operations, GUANXIAN RUICHANG TRADING CO., LTD. was founded in 2011 with a registered capital of 6 million Yuan. Operating as the direct exporting arm of the Xinrui Group, Ruichang Trading exports isolated soy protein, vital wheat gluten, soluble dietary fiber, vermicelli, and premium ethanol directly to overseas buyers from our production facility.
Exporting over 70% of the group's total industrial capacity, the integration of manufacturing and trading removes intermediaries. Global buyers gain direct access to factory pricing, secure supply pipelines, tailored logistics, and standardized quality assurance that meets local regulatory requirements in the EU, Americas, Asia-Pacific, and the Middle East.

Our VWG-PS Wheat Gluten Pellets are engineered using a specific temperature-regulated pelletization process. This prevents heat-induced protein denaturation, keeping the gluten protein native and preserving its cohesive binding capabilities. The resulting pellets exhibit exceptional stability during long-distance transit, while remaining highly soluble when exposed to moisture and mechanical shear in industrial mixers.
XINRUI GROUP, established in May 2003, covers a total industrial footprint of more than 1,000 mu. Over decades of systematic capital investment and technological expansion, the group has developed a robust circular industrial framework, including Guanxian Xinrui Industrial Co., Ltd., local cogeneration power facilities, urban municipal heating, municipal gas supply, and deep processing capacities for both wheat and soy.
Additionally, the group operates Shandong Kawah Oils Co., Ltd., which processes 180,000 tons of non-GMO soybeans annually. We maintain our own integrated wheat and non-GMO soybean planting bases, supporting raw material traceability. Our diversified industrial operations generate an annual output value of 2.8 billion Yuan, making us a highly reliable agricultural processing partner for multinational corporations.
Established in 2014 with a registered capital of 120 million Yuan, SHANDONG KAWAH OILS CO., LTD. operates as a leading agricultural industrialization enterprise in Shandong Province. The company integrates plantation management, research & development, deep molecular processing, and import/export operations.
Processing 180,000 tons of domestic Non-GMO soybeans annually, Kawah Oils produces soybean oil, low-temperature food-grade soybean meal, isolated soy protein, and dietary fibers. Our soy protein isolate facility features advanced spray drying towers imported from DACHUANYUAN, with a single-line capacity exceeding industry standard norms—making it one of the largest single-line soy protein manufacturing plants in China.
Continuous process optimization using next-generation green manufacturing and circular economic utilization.
Our tri-canter separation technology recovers A-starch, B-starch, and proteins with minimal freshwater usage. Solid effluents are recycled into municipal gas bio-digesters and agricultural feed mill additives, ensuring zero chemical runoff.
Conventional pelleting denatures vital gluten via friction-induced heat. Our low-temperature, steam-assisted pelletizers compress proteins within strict thermodynamic windows, maintaining gluten vitality and cohesive properties.
By leveraging municipal cogeneration systems and utilizing wheat byproduct streams for plant heating, we are actively reducing the carbon footprint of our wheat gluten production line to meet international scope 3 emission goals.
Transparent insight into our automated processing lines, storage silos, and logistics capabilities.
Our facilities meet rigorous food and feed safety standards, ensuring smooth customs clearance and regulatory compliance worldwide.

Our standard wheat gluten pellets have a diameter of 4mm to 6mm, with a Pellet Durability Index (PDI) exceeding 95%. This ensures minimal fines generation during pneumatic unloading and pneumatic conveying in bulk silos.
Because our low-temperature pelletization process avoids thermal denaturation, the gluten proteins retain their natural vitality. Upon rehydration and mechanical mixing, the pellets readily absorb water (minimum 150% absorption capacity) and form a highly viscoelastic, stretchy dough matrix identical to fresh wheat gluten powder.
We offer flexible packaging configurations including 25kg multi-wall paper bags, 1000kg bulk super sacks, and bulk pneumatic vessel shipments. Shipping terms include FOB, CFR, CIF, and DDP to major global ports.
