Premium functional proteins engineered for meat processing, vegan analog structures, high-dispersion nutritional beverages, and clean-label dietary products.
Driven by global dietary shifts toward plant-based nutrition, clean labeling, and food security requirements, Soya Bean Protein Powder—especially Isolated Soy Protein (SPI)—has evolved into a foundational functional ingredient for global food systems.
Globally, soy protein derivatives are essential across multiple food sectors. Large-scale food processing companies rely on the functional properties of soy proteins, such as gelling, emulsification, and water/fat binding, to improve product texture, nutrition profiles, and cost structure. From the high-yield meat processing plants of Latin America and Eastern Europe to the sports nutrition brands of North America and Europe, the demand for highly functional, stable, and Non-GMO soy ingredients continues to climb.
However, sourcing high-quality soy protein is challenging. Disrupted supply chains, fluctuating raw material costs, and strict regulatory standards require B2B buyers to partner directly with fully integrated manufacturers. Sourcing from verified Chinese producers offers major advantages in supply reliability, technical specialization, and pricing efficiency.
Established in 2003, Xinrui Group has built a diversified agricultural processing model spanning over 1,000 mu, achieving a circular economy that optimizes wheat and soy derivatives.
Established in 2014 with a registered capital of 120 million Yuan, Shandong Kawah Oils Co., Ltd. serves as a leading enterprise in agricultural industrialization. Our facility processes 180,000 tons of Non-GMO soybeans annually, utilizing trace-monitored domestic raw materials to extract Non-GMO soybean oil, low-temperature food grade soybean meal, isolated soy protein, and dietary fiber in an integrated, step-by-step loop.
Our spray drying equipment features a state-of-the-art Dachuanyuan spray drying tower. With a single-line capacity leading the region, it stands as the largest single production line in China, ensuring consistent batch consistency, particles configuration, and functional index stability.
Our sister entity, Guanxian Xinrui Industrial Co., Ltd. (formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd), established in 2007 with a registered capital of 100 million Yuan, processes 500,000 tons of wheat flour annually. Utilizing advanced tri-canter separation technology, this closed-loop system extracts vital wheat gluten, wheat starch A, wheat starch B, and pentosan—utilizing byproducts for cogeneration and regional heating systems.
Industrial scale combined with regional raw material sourcing and technological optimization delivers reliable supply, consistent quality, and competitive pricing.
Operating integrated wheat and Non-GMO soybean planting bases allows us to enforce strict identity preservation (IP). Every batch of soybean meal entering Shandong Kawah Oils is traceable, preventing cross-contamination with genetically modified varieties.
By utilizing advanced German and domestic tri-canter separation and spray drying systems, we control denaturation rates and protein dispersion speeds. This results in high nitrogen solubility index (NSI) numbers for dispersion types and superior gel networks for meat grades.
Our facility's circular economy utilizes cogeneration, urban heating, and gas supply systems. This reduces our dependence on external municipal utilities, lowers thermal production costs, and protects buyers from utility-driven price hikes.
Not all soy protein isolates are the same. We manufacture functional proteins tailored to specific industrial processes, formulations, and production parameters.
Grades: 9001BW, 9001B-Y, 9000, 9007B-A, 9007B-C, 9500
Designed for emulsified sausages, frankfurters, and canned meats. These grades bind water and fat in a 1:5:5 matrix, reducing cook shrink, stabilizing fat during thermal processing, and improving bite texture.
Grades: 9030, 9032
Engineered for dry-blend meal replacements, powdered proteins, and liquid RTD beverages. These low-viscosity isolates disperse quickly in water without clumping, providing neutral taste and mouthfeel.
Grades: 9003B, 9005B
Formulated for vegan burgers, plant-based seafood, and traditional block tofu. These grades provide the protein structure required to hold dietary fiber and wheat gluten in realistic meat-like textures.
| Functional Category | Typical Grades | Protein (Dry Basis) | Moisture | Ash | pH Value | Primary Industrial Use |
|---|---|---|---|---|---|---|
| Beverage & Dispersion | 9030 / 9032 | ≥ 90.0% | ≤ 7.0% | ≤ 6.0% | 6.8 - 7.5 | Meal replacements, dairy-free shakes, instant protein powders |
| Meat & Emulsification | 9001BW / 9007B-A / 9500 | ≥ 90.0% | ≤ 7.0% | ≤ 6.0% | 6.8 - 7.5 | Emulsified sausages, meatballs, ham injection systems |
| Vegetarian & Tofu | 9003B / 9005B | ≥ 90.0% | ≤ 7.0% | ≤ 6.0% | 6.8 - 7.5 | Meat alternatives, block tofu, high-gel vegetarian foods |
| Chopping Type | 9002B | ≥ 90.0% | ≤ 7.0% | ≤ 6.0% | 6.8 - 7.5 | High-speed bowl chopping meat operations, fine emulsification |
We operate a low-carbon, zero-waste processing loop where the output of one processing line fuels another.
Our wheat processing facility (500,000 tons/year) extracts wheat starch A and wheat gluten. The residual starch B and pentosan are recycled for industrial alcohol and ethanol production. Meanwhile, our cogeneration plant supplies energy for both the soybean oil extraction and wheat starch drying processes. This circular design cuts logistics emissions, lowers energy costs, and helps global B2B clients meet their Scope 3 ESG targets.
Closed-loop system that cuts water usage and guarantees product purity.
Captures thermal energy for drying systems, reducing fossil fuel dependence.
Handling international logistics, compliance certification, and direct factory-to-port export operations.
Founded in 2011 with a registered capital of 6 million Yuan, Guanxian Ruichang Trading Co., Ltd. is the dedicated export arm of Xinrui Group.
By managing logistics internally, we export over 70% of our production capacity directly to overseas buyers. This system eliminates third-party broker fees, shortens shipping times, and provides direct contact with our production engineers. We export isolated soy protein, wheat gluten, soluble dietary fiber, vermicelli, and food-grade ethanol to clients worldwide.
Our production processes follow international safety, dietary, and trace-liability standards. Shandong Kawah Oils and Guanxian Xinrui Industrial hold certifications from top auditing organizations.
