Advanced non-GMO plant proteins optimized for target-specific digestibility and maximum physical durability index (PDI) in premium feed manufacturing.
Understanding how protein molecular chemistry improves physical stability, nutritional density, and aqua-feed water performance.
Vital Wheat Gluten Pellets (VWG-PS) and Soy Protein Isolates act as functional biological binders. By utilizing the native viscoelastic properties of gliadin and glutenin, our binders establish a cohesive polymeric network within the pellet structure during extrusion, securing high durability.
For aquaculture, pellet disintegration can lead to feed waste and water pollution. Utilizing isolated proteins with high emulsifying and thermal gelation capabilities extends aquafeed stability up to 12 hours without impacting nutrient absorption or release kinetics.
Unlike mineral-based or synthetic chemical binders, our plant-based proteins add nutritional value. Crucial amino acid profiles (lysine, methionine, threonine) remain active, providing animal operations with a biological dual-advantage: optimal physical shape and nutritional density.
| Functional Binder Grade | Protein Content (Dry Basis) | Water Absorption Index | Pellet Durability Index (PDI) Improvement | Primary Target Fields |
|---|---|---|---|---|
| Vital Wheat Gluten Pellets (VWG-PS) | ≥ 75% - 82% | 150% - 200% | +15% to +25% | Sinking Aquafeed, Shrimp Feed, High-Density Livestock Feed |
| Isolated Soy Protein (Emulsion Grades) | ≥ 90% | 250% - 300% | +10% to +18% | Larval/Starter Feeds, Pet Foods, Calving Replacements |
| Functional Soy Protein Concentrate | ≥ 65% - 70% | 120% - 160% | +8% to +12% | General Livestock, Poultry Pre-mixes, Piglet Starters |
GUANXIAN XINRUI INDUSTRIAL CO., LTD. (formerly known as GUANXIAN RUIXIANG BIOTECHNOLOGY DEVELOPMENT CO., LTD) was established in 2007 with registered capital of 100 million Yuan. We process over 500,000 tons of wheat flour annually, integrating wheat gluten, starch A, and starch B production alongside eco-friendly animal feed and alcohol processing lines.
Our operation processes raw agricultural inputs into value-added protein matrices. Starch B and pentosan are recycled directly into bio-energy (ethanol) and optimized animal feed pellet raw materials. This closed-loop design ensures full utilization and shields global buyers from price volatility.
Advanced Tri-Canter Technology: We imported high-performance tri-canter separation equipment for our wheat gluten production lines. The system operates in a completely enclosed, sanitary, automated system, positioning our production capacity, quality levels, and process safety at the forefront of the industry.
Integrated International Export Matrix: GUANXIAN RUICHANG TRADING CO., LTD. was established in 2011 with a registered capital of 6 million Yuan. It manages direct global distribution of the group’s soy protein isolates, wheat gluten, dietary fibers, vermicelli, and ethanol. More than 70% of our capacity goes directly to international markets, ensuring smooth customs processing and professional logistics.
Diversified corporate matrix generating an annual output of 2.8 billion Yuan across agricultural cultivation, deep processing, energy cogeneration, and global trade.
Established in 2014 with 120 million Yuan in registered capital, Shandong Kawah Oils is a provincial leading enterprise in agricultural industrialization. Processing 180,000 tons of domestic Non-GMO soybeans annually, it operates the largest single production line in China, featuring state-of-the-art Japanese Dachuangyuan spray drying towers.
We utilize low-temperature extraction technology to yield clean food-grade meal, high-emulsification isolated soy proteins, and dietary fiber. Our integrated farming bases ensure complete trace-back verification for global bio-security compliance.
Applying biochemical properties to address processing challenges in the aquaculture, livestock, and pet food industries.
Sinking feeds for shrimp and crabs require long-term structural water stability. Using Vital Wheat Gluten (VWG-PS) and Soy Protein Isolate binders maintains pellet density, reduces leaching of micro-nutrients, and limits water decomposition, improving Feed Conversion Ratios (FCR).
Excessive feed dust reduces feed intake and triggers respiratory problems in livestock. Our organic binders improve pellet hardness (PDI), significantly reducing fines during transport and dry silo handling.
Modern pet diets require appealing textures and non-allergenic, plant-based protein profiles. Our functional isolates improve moisture retention during thermal extrusion, creating consistent kibble shapes and dense nutritional value.
Demonstrated operational transparency. Review our certifications and advanced facility video tours.
A broad portfolio of protein isolates, dispersion agents, dietary fibers, and functional food/feed-grade binders.
Explore raw materials developed, refined, and distributed directly from our production site.
Providing supply stability for international manufacturers through structured risk management.
Our proximity to major northern Chinese shipping ports allows for efficient transport routing. We offer bulk options, container shipping (FCL/LCL), and specialized packaging to prevent moisture ingress during long sea routes.
Every shipment is trace-verified to our farming bases. Our Non-GMO soy proteins feature IP program documentation, protecting international buyers from regulatory non-compliance issues.
From 25kg multi-wall paper bags with PE inner liners to 1000kg bulk supersacks, we support customized labeling, localized language compliance, and palletized options.
Crucial information regarding procurement, specifications, production, and quality protocols.
We are a vertically integrated group company named Xinrui Group. The manufacturing plant for our soy protein isolates is Shandong Kawah Oils Co., Ltd., which produces 50,000 tons of isolated soy protein annually. The manufacturing facility for our wheat gluten is Guanxian Xinrui Industrial Co., Ltd. (formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd), producing 30,000 tons of vital wheat gluten annually. The export and trade operations are managed directly under our specialized trading arm, Guanxian Ruichang Trading Co., Ltd.
Our operations hold international quality and safety certifications, including HACCP, ISO9001, ISO22000, BRC, HALAL, KOSHER, and IP-NON GMO verified by SGS. We can also arrange additional third-party inspection certifications (e.g., CIQ, SGS analysis) upon request.
Vital wheat gluten is high in insoluble protein fractions, gliadin and glutenin. When exposed to water and thermal extrusion, these proteins form an elastic cross-linked network. This matrix binds starch grains and fiber fragments together, increasing pellet hardness and minimizing fine generation during handling.
Under dry, ventilated storage conditions (relative humidity ≤ 60%, temperature ≤ 25°C), our isolated soy proteins and vital wheat gluten maintain their physical and nutritional properties for 12 to 24 months. Product packaging should remain sealed until use to prevent moisture absorption.
Yes. Through our integrated production facility, we can adjust parameters such as viscosity, gelation properties, dispersion speed, and mesh size to meet the specific requirements of our clients' feed formulations.
