Direct supply from state-of-the-art production facilities under strict ISO & BRC quality control standards.
In the highly competitive global animal feed sector, maximizing nutritional efficiency while controlling costs is a core priority. Feed Grade Vital Wheat Gluten (VWG) has emerged as an indispensable functional ingredient. Extracted from premium non-GMO wheat flour using state-of-the-art separation systems, vital wheat gluten is a natural, insoluble plant protein matrix characterized by its exceptional viscoelasticity, high digestibility, and unique water-binding capabilities.
Unlike standard plant protein substitutes, vital wheat gluten provides a high concentration of crude protein (typically 75% to 82% dry basis) with an excellent digestibility profile exceeding 95% in aquaculture species and young piglets. This superior digestibility significantly mitigates environmental pollution in aquaculture systems by minimizing nitrogen excretion. In addition, its functional rheological properties act as a natural binder, optimizing pellet durability, reducing dust generation, and preventing nutrient leaching in water.
By replacing expensive animal proteins (such as high-grade fishmeal) with our functional Feed Grade Vital Wheat Gluten, feed formulators can achieve comparable or superior feed conversion ratios (FCR) while lowering overall formulation costs. This is supported by our fully integrated circular economy model, ensuring pricing stability and traceability.
Integrating modern agriculture, advanced bioprocessing, and international trade to deliver cost-optimized ingredients.
Established in May 2003, Xinrui Group spans a total footprint of more than 1,000 mu. Over decades of systematic expansion, we have built a highly integrated industrial ecosystem comprising sustainable agricultural planting, urban cogeneration heating, and advanced plant protein processing lines.
Under the group's umbrella, Guanxian Xinrui Industrial Co., Ltd. (formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd.), established in 2007, operates a modern wheat processing plant with an annual milling capacity of 500,000 tons. Utilizing advanced tri-canter separation technology, we fractionate premium wheat into Vital Wheat Gluten, Wheat Starch A, and Wheat Starch B.
Maximizing Value Through Circular Economy: Starch B and pentosans are routed directly into our integrated fermentation lines to produce high-grade industrial and food ethanol, alongside premium animal feed byproducts. This zero-waste approach minimizes manufacturing costs, shielding our customers from raw material market fluctuations.
Our sister enterprise, Shandong Kawah Oils Co., Ltd., established in 2014 with 120 million Yuan registered capital, processes 180,000 tons of non-GMO soybeans annually. Operating the largest single spray-drying line in China (designed by DACHUANYUAN), Kawah Oils produces 50,000 tons of high-purity Isolated Soy Protein (ISP) per year, establishing our group as a global leader in plant protein sourcing.
Explore the physical and chemical profiles of our Feed Grade Vital Wheat Gluten varieties.
Our feed grade wheat proteins are manufactured under highly controlled sanitation parameters. By utilizing imported tri-canter centrifuge systems, we separate the gluten proteins (gliadin and glutenin) without damaging their native structures, ensuring excellent water absorption (over 150%) and viscoelastic recovery. This structural integrity makes it highly effective for pellet binding in aquafeeds and pet foods.

Addressing the shifting paradigm in sustainable animal feed and premium protein sourcing.
Shrimp and carnivorous fish feeds require exceptional water stability to prevent nutrient leaching. The viscoelastic properties of Vital Wheat Gluten form a cohesive network that locks in nutrients, reducing feed waste and maintaining water quality.
Modern pet food brands are moving away from synthetic texturizers. Vital Wheat Gluten serves as a clean-label binder and high-protein ingredient that improves kibble structure and crunchiness while providing essential amino acids.
With volatile marine protein prices, formulators are looking to plant-based proteins. Vital Wheat Gluten offers an optimal amino acid balance and low fiber content, making it an excellent alternative to premium fishmeal.
Continuous innovation in plant protein extraction, enzymatic modification, and automated processing.
Our raw material wheat is sourced directly from contracted farming bases under strict pesticide and GMO control, ensuring consistent flour quality before wet milling.
We utilize imported tri-canter centrifuges to gently separate starch and protein fractions, keeping process temperatures low to preserve the functional properties of the gluten.
Gluten slurry is dried using a low-temperature flash drying system, ensuring the protein's native structure and water absorption capacity are maintained.
Our team is developing partially hydrolyzed wheat protein options to further improve digestibility in early-weaned piglets and larval aqua feeds.
