Premium functional isolated soy proteins, high-grade ethanol, and vital wheat gluten ingredients processed under strict international standards.
XINRUI GROUP was established in May 2003, covering a total area of more than 1,000 mu. Following decades of integrated growth, we have developed into a highly diversified agricultural deep-processing collective with an annual production value of 2.8 billion Yuan. Our dynamic industrial layout spans from primary crop sourcing to advanced biochemical refinement, operating through core units including GUANXIAN XINRUI INDUSTRIAL CO., LTD. (formerly known as GUANXIAN RUIXIANG BIOTECHNOLOGY DEVELOPMENT CO., LTD) and SHANDONG KAWAH OILS CO., LTD.
Our infrastructure includes self-owned municipal-grade cogeneration plants for combined heat, power, and gas supply. This secures an uninterrupted, thermally stable environment for our high-capacity spray drying towers, ensuring steady operation and premium quality. By eliminating localized power grid instabilities and raw energy fluctuations, we offer reliable volume deliveries to global food groups.
To bridge manufacturing scale with global client requirements, GUANXIAN RUICHANG TRADING CO., LTD. was established in 2011 with 6 million Yuan in registered capital. Ruichang Trading oversees all direct exports, sending over 70% of the group's production volume—including isolated soy protein, vital wheat gluten, soluble dietary fiber, vermicelli, and ethanol—to clients worldwide.
Our manufacturing advantages are built on complete integration and advanced processing technologies. SHANDONG KAWAH OILS CO., LTD., founded in 2014 with 120 million Yuan in registered capital, is a leading provincial enterprise in agricultural industrialization. Our production line integrates raw material cultivation, advanced R&D, deep processing, and import/export channels.
We source local NON-GMO soybeans and extract high-purity edible soy oil, low-temperature defatted soy meal, isolated soy protein, and dietary fiber in an integrated processing flow. Our facility features a state-of-the-art spray drying tower from DACHUANYUAN. This system is the largest single-line spray drying unit in China, delivering consistent particle size, moisture control, and dispersion properties.
On the grain processing side, GUANXIAN XINRUI INDUSTRIAL CO., LTD. processes 500,000 tons of wheat flour annually. Using advanced tri-canter wet separation technology imported from Europe, we process wheat into high-purity vital wheat gluten and wheat starch (A and B grades). The starch byproducts and pentosans are directed into our integrated industrial systems to manufacture premium-grade bio-ethanol and animal nutrition feed, achieving a highly efficient circular economy.
Our closed-loop, automated processing systems protect product purity and functional integrity. High-pressure spray drying at Kawah Oils keeps the nitrogen solubility index (NSI) high while maintaining excellent water binding and emulsification properties. In our wheat line, tri-canter separation uses physical centrifugation rather than chemicals, protecting the native viscoelastic matrix of our Vital Wheat Gluten. This results in superior stretch, gas retention, and structural strength in baking and meat applications.
In B2B food applications, isolated soy protein is valued for both its nutritional profile and its key functional properties: water binding, oil emulsification, gelation, and dispersion. Shandong Kawah Oils manufactures specialty isolates tailored to specific industrial uses:
These grades are engineered to build strong protein networks that bind water and fat during thermal processing. They are ideal for high-speed chopping and emulsification lines (e.g., frankfurters, sausage links, meatballs), preventing syneresis and improving bite texture.
Specially processed to prevent sedimentation in liquid systems. These isolates hydrate quickly at neutral pH, offering low viscosity at high concentrations. They are ideal for meal replacements, protein beverages, dairy alternatives, and nutritional powder blends.
Formulated with a balanced ratio of 7S and 11S globulins to yield smooth curd textures and cohesive structures. These types are designed for traditional tofu production, plant-based seafood, and structured meat analogs.
Large food manufacturers require consistent functional performance. Our laboratory monitors key quality metrics, including:
Navigating global regulatory landscapes requires rigorous quality assurance. Shandong Kawah Oils and Guanxian Xinrui Industrial maintain a comprehensive certification portfolio to meet international market requirements.
Our raw material supply chain relies on strict IP Non-GMO tracking systems. From seed selection and planting to harvesting, transportation, defatting, and final isolation, every batch is verified to prevent GMO cross-contamination. This ensures full compliance with strict European and North American regulations.
We provide complete documentation—including trace analyses, allergen management plans, heavy metal assays, and microbiological profiles—to streamline customs clearance and quality approvals for international food brands.

The global plant-based protein market is transitioning from simple meat alternatives to high-functional, clean-label systems. As international buyers source raw ingredients, several key trends shape the market:
Modern consumers seek shorter ingredient lists with fewer additives. Functional soy proteins are designed to replace chemical stabilizers and emulsifiers, providing high water binding and emulsifying properties using only physical extraction.
Sustainable production is increasingly vital. By combining wheat milling, oil extraction, protein isolation, and co-generation, we reduce our carbon footprint, lower operational waste, and improve resource efficiency.
Beyond texture, plant-based proteins must meet specific nutritional needs. High digestibility (PDCAAS score close to 1) and balanced amino acid profiles make isolated soy proteins the primary choice for sports nutrition, clinical diets, and infant formulas.
