Explore our foundational range of isolates, dietary fibers, and functional wheat formulations.
The global demand for high-purity protein ingredients has reached unprecedented levels, driven by the structural rise of meat alternatives, clean-label food formulations, and nutritional supplements. At the core of this transition is Soy Protein Isolate 90% (SPI 90), a versatile ingredient that offers exceptional functional performance in emulsion, water binding, gelation, and dispersibility.
Establishment in 2003 marked the beginning of **Xinrui Group**. Spanning an industrial territory of over 1,000 mu and generating an annual output value exceeding 2.8 billion Yuan, we have developed a highly integrated, zero-waste agricultural processing circular economy. Our group encompasses diversified enterprises, including Guanxian Xinrui Industrial Co., Ltd. (processing 500,000 tons of wheat flour annually) and Shandong Kawah Oils Co., Ltd. (processing 180,000 tons of domestic Non-GMO soybeans annually).
By controlling the entire process from crop cultivation in our dedicated Non-GMO planting bases to refining and spray-drying, we deliver reliable raw materials directly to global brands, processing factories, and distributors.
How our advanced processing engineering yields soy protein isolate with optimal functional traits.
We source raw soybeans directly from certified Non-GMO planting bases. By maintaining strict Identity Preservation (IP) protocols, we guarantee traceabilities from field cultivation, harvest, transport, to crushing, ensuring zero contamination.
Shandong Kawah Oils Co., Ltd. features the state-of-the-art DACHUANYUAN spray drying tower. Operating as one of the largest single-line capacity systems in China, it facilitates quick, low-temperature water evaporation to prevent heat denaturation of proteins.
Imported tri-canter separation machinery is deployed in our wheat gluten production lines. This highly advanced separation engineering preserves native protein structures while achieving continuous, clean, and closed-loop operation.
At our manufacturing facility, raw soybeans are processed systematically to yield value-added derivatives. After low-temperature crushing and oil extraction, the defatted soybean flakes are processed through precise chemical extraction, acid precipitation, neutralization, and ultra-high-temperature (UHT) flash sterilization.
This closed loop prevents exposure to external contaminants, yielding consistent physical-chemical properties across every batch. Our circular model ensures that sub-products like pentosan, starch B, and soy dietary fiber are routed to secondary applications (such as animal feed and bio-ethanol production), lowering operational overheads and our environmental footprint.
Different manufacturing requirements dictate unique physical properties. Below is our professional grade formulation guide for industrial applications:
| Application Category | Target Product Grades | Key Performance Indicator | Industrial Processing Advantages |
|---|---|---|---|
| Meat & Emulsion | 9001BW, 9001B-Y, 9000, 9007B-A, 9007B-C, 9500, 9001BH, 9006B | High Emulsification & Water Retention | Promotes uniform fat-water-protein binding. Inhibits syneresis during cooking, improving bite texture and yield in sausages and frankfurters. |
| Saline Injection | 9020, 9026, 9028 | Ultra-low Viscosity & High Solubility | Dissolves instantly in brine solutions without clogging injection needles. Disperses evenly within whole muscle fibers of ham and bacon. |
| Vegetarian & Traditional Foods | 9003B, 9003BA, 9005B | Strong Thermal Gelation & Elasticity | Forms resilient, elastic protein networks upon heating. Ideal for structured vegetarian sausages, surimi, and tofu formulations. |
| Beverages & Nutrition | 9030, 9032 | High Dispersibility & Neutral Taste | Ensures low sediment formation in water. Provides a neutral sensory profile, perfect for protein powders, dietary shakes, and soy milk formulas. |
A closer look inside our advanced manufacturing workshops, showing processing lines and quality control practices.
Exporting over 60-70% of our output directly to clients globally requires strict adherence to international safety regulations. Our laboratories are equipped with modern analytical instruments to monitor heavy metal levels, microbiological indices, and protein concentration across all production lots.
We hold certifications including IP-NON GMO, BRC, ISO22000, ISO9001, HACCP, HALAL, and KOSHER. Each batch of Soy Protein Isolate 90% is traceable to the crop shipment level, providing safety and reliability for global food brands.
