Vital Wheat Gluten (VWG), also known as active wheat protein, is a highly functional natural plant protein derived from the separation of wheat flour. In the global commercial market, feed-grade Vital Wheat Gluten has emerged as a cornerstone ingredient for premium aquaculture feeds, pet food formulations, and specialized weaning diets. As global animal production shifts toward sustainable, non-animal-derived proteins, the demand for highly digestible, allergen-safe vegetable protein sources has escalated dramatically.
Our feed-grade wheat gluten presents a protein content of 75% to 80% (dry basis), characterized by a well-balanced amino acid profile rich in glutamic acid, proline, and hydrophobic amino acids. Unlike synthetic binders or generic filler flours, wheat gluten retains its viscoelastic matrix. This physical architecture is pivotal for maintaining the structural stability of feed pellets in water, crucially preventing nutrient leaching in commercial aquaculture ponds.
Furthermore, global supply chains face mounting pressures due to logistical complexities and strict regulatory guidelines. Large-scale feed mills and international importers seek partners capable of delivering massive, consistent volumes that strictly comply with mycotoxin thresholds, heavy metal regulations, and GMO restrictions. With the rising prices of fishmeal and soy protein concentrate, feed-grade wheat gluten acts not only as a functional physical binder but also as a biological source of highly bioavailable energy and amino acids, optimizing feed conversion ratios (FCR).
Set up in 2007 with registered funds of 100 million Yuan, Guanxian Xinrui Industrial Co., Ltd. (formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd) is a cornerstone manufacturer under the Xinrui Group. The company has a processing capacity of 500,000 tons of wheat flour annually, extracting wheat gluten, wheat starch A, and wheat starch B. Starch B and pentosan are systematically funneled into producing premium ethanol and high-performance animal feed, executing a state-of-the-art circular economy industry chain.
We imported the world's most advanced tri-canter separation technology for wheat gluten production. Our entire production line is clean, closed, and optimized for bio-security. Our overall output value, machinery advancement, and product consistency stand at the vanguard of the global starch and protein processing sectors.
Established in 2014 with a registered capital of 120 million yuan, Shandong Kawah Oils Co., Ltd. is a leading agricultural industrialization enterprise processing 180,000 tons of domestic NON-GMO soybeans annually. Integrating plantation, R&D, deep processing, and export operations, Kawah Oils processes soybean meal, isolated soy protein (ISP), and soy dietary fiber. Featuring spray drying towers from DACHUANYUAN, Kawah Oils operates the largest single production line in China, ensuring massive product throughput and stability.
Guanxian Ruichang Trading Co., Ltd., founded in 2011 with 6 million yuan of registered capital, acts as the direct export integration vehicle of the group. Exporting isolated soy protein, wheat gluten, soluble dietary fiber, vermicelli, and ethanol directly to global clients, overseas trade now represents over 70% of the group's total production capacity.

Understanding how physical properties translate into performance benefits across diverse agricultural and aqua-farming sectors.
Vital wheat gluten is extensively used as a natural binder in aquaculture feeds. When hydrated, it forms a cohesive, viscoelastic network that ensures feed pellets survive water immersion. This significantly reduces dissolved particulate waste, protects water quality, and guarantees bottom feeders like shrimp can ingest the complete formulation before disintegration.
For pet kibble and canned wet pet food, our wheat gluten acts as a texturizing agent, yielding uniform kibble structural strength. In wet pet food, it binds gravy and mimics natural meat muscle fibers (chunk-in-gravy formulations), enhancing both visual appeal and palatability while ensuring high protein values are met.
Weaning piglets have extremely sensitive digestive tracks that cannot process harsh plant antinutrients. Because our vital wheat gluten undergoes clean, gentle physical separation, the digestible energy and protein availability are exceptionally high (digestibility coefficients exceeding 95%), minimizing diarrhea and supporting critical early gut development.
Why Guanxian Xinrui represents the peak of Chinese supply-side efficiency and technology.
At the center of our production efficiency is the integration of physical wet-milling with state-of-the-art tri-canter separation technology. This process separates the native wheat flour slurry into gluten, heavy starch A, and light starch B continuously under zero-chemical-additive conditions. By using centrifugal force rather than high temperatures or chemical extraction, we ensure that the gluten protein remains native, preserving its elastic qualities, and maintaining high water absorption ratios of 150-180%.
Additionally, our circular economy design reduces environmental overhead. The residual Starch B and pentosans are not disposed of as waste; instead, they are immediately fed into our adjoining ethanol processing plants. The energy cogeneration plant operates seamlessly to power the spray dryers and drying drums. These operational loops dramatically lower the manufacturing carbon footprint and operational costs, a pricing advantage that we pass directly to our global wholesale clients.
