Explore our core collection of isolated proteins, dietary fibers, and foundational starch products engineered for superior functionality and nutritional integrity.
In the modern food processing industry, Isolated Soy Protein (ISP) represents the pinnacle of plant-based protein technology. Functioning as a high-concentration ingredient, ISP contains 90% or more protein on a dry basis, virtually free of fat, carbohydrates, and dietary fibers. The global market demand for premium soy isolates is driven by three main factors: the exponential growth of alternative meats (meat analogues), the nutritional enhancement of dairy-free beverages, and the functional necessity for binding agents in emulsified meat products.
Geopolitically, the supply chain for isolated soy is undergoing a major shift. B2B procurement executives are moving away from multi-tiered trading setups to establish direct partnerships with primary processors. This ensures strict non-GMO traceability (IP Non-GMO certification), supply security, and customized functional parameters like specific gel strengths, viscosity limits, and dispersibility factors.
Unifying crop processing, clean technology, and global logistics under a single industrial group.
Established in May 2003, XINRUI GROUP has built a diversified agricultural processing cluster covering more than 1,000 mu. Driven by resource efficiency, the group integrates municipal cogeneration, urban heating, gas supply, and deep agricultural processing to achieve an annual output value of 2.8 billion Yuan.
Our primary crop processing division, GUANXIAN XINRUI INDUSTRIAL CO., LTD. (formerly GUANXIAN RUIXIANG BIOTECHNOLOGY DEVELOPMENT CO., LTD), was set up in 2007 with a registered capital of 100 million Yuan. Processing 500,000 tons of wheat flour annually, the facility utilizes state-of-the-art, closed-loop tri-canter separation technology imported from leading engineering firms. This advanced system divides wheat raw materials into high-purity vital wheat gluten, wheat starch A, and wheat starch B. The residual starch B and pentosan are recycled directly into our ethanol division and animal feed processing systems, completing our circular value chain.
Established in 2014 with 120 million Yuan in registered capital, SHANDONG KAWAH OILS CO., LTD. is a leading provincial enterprise for agricultural industrialization. Integrating crop cultivation, research and development, deep molecular extraction, and import/export trade, the factory processes 180,000 tons of domestic Non-GMO soybeans annually.
Using traceable domestic soybeans, the facility extracts high-grade Non-GMO soybean oil, low-temperature food-grade soybean meal, isolated soy protein, and dietary fiber. The core drying unit is equipped with a high-capacity spray drying tower from DACHUANYUAN, which powers the largest single isolated soy protein production line in China.
Founded in 2011 with 6 million Yuan in registered capital, GUANXIAN RUICHANG TRADING CO., LTD. serves as the group's global trading engine. Ruichang exports isolated soy protein, wheat gluten, soluble dietary fiber, vermicelli, and food-grade ethanol directly to international buyers. Handling over 70% of the group’s total production capacity, it guarantees clear shipping lines, customs clearance, and direct-from-factory pricing.
Our production efficiency is built on two main pillars: economies of scale and process integration. Our raw materials are sourced directly from our dedicated wheat and Non-GMO soybean planting bases, minimizing transit times, preventing cross-contamination, and securing stable input costs.
Inside the factory, our processing operations are closely integrated. Thermal energy and electricity generated by our cogeneration plant are routed directly to our spray drying towers and starch concentration evaporators. This setup reduces primary energy consumption, shortens production times, and lowers overall carbon emissions. By replacing traditional batch processing with continuous-loop systems, we achieve consistent batch characteristics, with protein levels, particle size distributions, and ash content remaining well within strict B2B tolerance limits.
Installed across our wheat processing lines, this closed separation technology yields high-purity Vital Wheat Gluten while minimizing water consumption and waste.
Our large-scale spray drying tower ensures gentle moisture removal, preserving the protein's native gel strength, emulsification properties, and solubility profiles.
We formulate and supply custom functional grades of Isolated Soy Protein to meet the specific requirements of international food processors.
Primary Grades: 9001BW, 9006B, 9007B-A, 9007B-C, 9500
Designed with high water-binding and oil-emulsifying properties, these grades stabilize water-and-fat matrices in sausages, hot dogs, and meatballs. They prevent fat separation during thermal processing and improve product bite and texture.
Primary Grades: 9020, 9026, 9028
Characterized by low viscosity and quick dispersibility, these grades dissolve rapidly in cold water without clogging injection needles. They are ideal for hams, bacon, and whole-muscle poultry, enhancing yields and maintaining tenderness.
Primary Grades: 9030, 9032
Engineered for high solubility, excellent dispersion, and low dust levels, these proteins are optimized for neutral-pH beverages, dry-mix protein shakes, and dairy alternatives, providing a smooth mouthfeel with no grittiness.
Primary Grades: 9003B, 9005B
Formulated to create strong, elastic, and heat-reversible gels, these grades are ideal for traditional tofu, vegetarian meats, and plant-based seafood, delivering a firm, clean bite.
Primary Grades: Food-grade SDF
Extracted from Non-GMO soy hulls, this dietary fiber offers high water-holding capacity and nutritional value. It is widely used to improve crumb structure in baking and enhance fiber content in health foods.
Primary Grades: Non-GMO SPC
A cost-effective protein option with good functional binding properties, ideal for processed meats, bakery products, and pet foods.
Modern procurement teams require more than just technical specifications; they need reliable supply chain compliance and risk mitigation. For isolated soy protein, this centers on certified non-GMO status. Our plant-based ingredients are fully traceable back to our planting bases, backed by Identity Preservation (IP) Non-GMO certification.
Our production plants maintain rigorous food safety management systems, supported by regular third-party audits. By sourcing directly from a vertically integrated manufacturer, international buyers can reduce price volatility, secure reliable shipping lines, and ensure consistent quality across all production batches.
To verify our circular economy model and industrial scale, please review our direct facility photos. These show our integrated wheat processing plants, grain silos, and soy extraction systems. Our operations are designed to balance high output with environmental responsibility, using waste-recycling systems to reduce energy and water intensity.
