Vital Wheat Gluten (VWG) is the natural, insoluble protein cohesive matrix extracted from premium wheat flour. Historically utilized in powder form, the global industrial sector has undergone a massive structural shift toward pelletized vital wheat gluten. As an advanced formulation, VWG Pellets address major logistical challenges by offering significantly improved bulk density, eliminating the dust explosion risks inherent in fine organic powders, and ensuring seamless pneumatic transfer in high-throughput feed manufacturing facilities.
Today, the aquaculture and livestock feed markets demand absolute raw material consistency. VWG-PS Pellets serve as a fundamental structural binder and high-concentration plant protein source. Operating in this space, Guanxian Xinrui Industrial Co., Ltd. (formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd) has established itself as a world-class manufacturing powerhouse, integrating raw wheat processing, starch extraction, and pelletized gluten manufacturing into a highly optimized, sustainable circular ecosystem.
From aquaculture extrusion to pet kibble texturizing, pelletized wheat gluten provides dual benefits of nutrition and physical structure.
For shrimp and salmon feeds, water stability is paramount. The viscoelastic properties of Vital Wheat Gluten act as a natural structural binder, ensuring that feed pellets maintain their shape and nutritional matrix underwater, reducing waste and protecting water quality.
Boasting a dry-basis protein content exceeding 75-80%, VWG pellets present an incredibly digestible amino acid profile, rich in glutamine and proline, which supports intestinal health and growth performance in young livestock and aquaculture species.
Powdered wheat gluten poses severe dust-explosion hazards and is prone to clumping in silos. VWG-PS pellets feature optimized particle size distribution, exhibiting excellent free-flowing properties, minimized dust generation, and easier unloading.
We leverage advanced wet milling technology utilizing the imported, cutting-edge tri-canter separation technology in our wheat gluten production line. Unlike outdated wash methods, the tri-canter process is fully enclosed and continuous. It separates the wheat flour slurry into three distinct phases:
This integrated circular strategy ensures that virtually 100% of the wheat grain is utilized, producing zero environmental wastewater and driving down production costs, which we pass on to our wholesale partners as pricing advantages.

Xinrui Group, founded in May 2003, spans over 1,000 mu and generates an annual output value of 2.8 billion Yuan. We operate multiple interconnected facilities that optimize resource efficiency. Our structural integration includes:
Our facilities undergo rigorous international auditing to ensure full compliance with the strict safety and dietary requirements of markets worldwide.
Watch our production lines, drying systems, and quality control labs in action.
Critical technical and logistical information for global buyers and procurement managers.
We are an integrated group company named Xinrui Group that controls both raw material cultivation, processing, manufacturing, and direct export trading. The processing of our vital wheat gluten is handled by Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd), producing 30,000 tons of vital wheat gluten per year. Our non-GMO isolated soy protein is manufactured by our sister entity, Shandong Kawah Oils Co., Ltd., which has a capacity of 50,000 tons per year. All international shipping, documentation, and contract structures are cleared directly via our specialized export division, Guanxian Ruichang Trading Co., Ltd.
We hold international certifications including HACCP, ISO9001, ISO22000, BRC, HALAL, KOSHER, and IP-NON GMO. We also work with third-party testing agencies like SGS to provide pre-shipment inspections and certificates of analysis (COA) according to client specification sheets.
When kept in cool, dry conditions below 25°C with a relative humidity under 60%, the shelf life of our Vital Wheat Gluten Pellets is 24 months. Store in original sealed packaging, away from strong odors and moisture.
We source our wheat from dedicated wheat-planting bases with controlled pesticide and heavy metal exposure. In our laboratory, we analyze every batch for lead, arsenic, and pesticide residues using atomic absorption spectroscopy to ensure compliance with global feed and food limits.
