Premium soybean isolate and agricultural formulations optimized for global food processors, meat industries, and beverage manufacturers.
The manufacturing of premium-grade Isolated Soy Protein (ISP) is a highly complex process requiring precise control over chemical, physical, and thermal parameters. Our modern processing plant utilizes advanced low-temperature extraction technology starting from strictly monitored Non-GMO Soybeans. The isolation of soy globulins (mainly 7S and 11S proteins) from soybean meal is achieved through a multi-stage process of solubilization at mild alkaline pH, followed by acid precipitation at the isoelectric point (pH 4.5).
By optimizing these extraction ratios, we guarantee that our soy proteins maintain their natural bio-activity, offering superior gelation, emulsification, water-binding, and fat-absorption properties. Our core technical advancement lies in the spray drying systems. Shandong Kawah Oils Co., Ltd. operates the largest single production spray-drying line in China, powered by the advanced DACHUANYUAN spray drying tower. This ensures consistent particle size distribution, outstanding solubility indexes, and excellent thermal stability, preventing protein denaturation during downstream processing.
How different industries utilize our specific protein formulations to enhance texture, yield, and nutritional profile.
For sausages, frankfurters, and meat batters, models like 9001BW, 9007B-C, and 9500 act as powerful structural binders. They form strong heat-irreversible gels that lock in water and fat, preventing separation during cooking, decreasing formulation costs, and enhancing product texture.
Designed for rapid dispersion and stability. High-Quality 9030 & 9032 Dispersion Type Proteins are engineered for nutritional powdered mixes, protein bars, ready-to-drink (RTD) dairy alternatives, and infant formulas, ensuring low viscosity and smooth mouthfeel.
As plant-based diets surge globally, our 9003B and 9005B Vegetarian Proteins supply high water-binding capacity and unique viscoelastic properties needed to replicate the fibrous bite of whole muscle meats, traditional tofu, and meat alternatives.
Founded in May 2003, Xinrui Group spans a massive footprint of over 1,000 mu, driving diversified agricultural processing, cogeneration, municipal heating, and gas supply. This deeply integrated structure supports a low-carbon, circular economy that is highly efficient:
In the modern international market, supply chain reliability is paramount. Guanxian Ruichang Trading Co., Ltd. (founded in 2011 with a registered capital of 6 million Yuan) functions as the specialized import/export arm of Xinrui Group. By integrating factory production and foreign trade, we export directly from our manufacturing facilities to over 50 countries, covering Europe, North America, Southeast Asia, and South America.
Our strategic plant placement in Shandong Province, China, provides close proximity to major deep-water ports (such as Qingdao Port), enabling streamlined containerized and bulk ocean freight. By owning our dedicated cogeneration facilities and direct agricultural planting bases, we buffer our global clients from energy cost fluctuations and volatile raw material pricing, ensuring a consistent supply of soy protein isolates and wheat gluten throughout the year.
We utilize the most advanced separation technologies, including tri-canter separator systems for wheat proteins, and large-scale automated spray drying towers for soy isolates.
For vital wheat gluten and starch production, we imported advanced tri-canter separation systems. The entire manufacturing process operates in a fully enclosed, sanitary, clean-in-place (CIP) environment, ensuring peak purity and microbiological safety. The resulting Vital Wheat Gluten (VWG-P and VWG-PS) provides exceptional elasticity, cohesion, and water absorption capacity, ideal for baking, meat processing, and high-performance animal feeds.
Our non-GMO soy dietary fiber (SDF) lines process soybean cotyledon materials to extract highly functional dietary fiber. Combining high water-holding, oil-holding, and swelling capacities, this dietary fiber serves as an excellent fat replacer and texturizer in clean-label baked goods, processed meats, and dietary supplements.
We maintain rigorous quality management frameworks to comply with international food safety standards across global regions.

We are a large diversified group company named Xinrui Group integrating manufacturing, domestic distribution, and direct global exporting.
Our subsidiary, Shandong Kawah Oils Co., Ltd, is the dedicated manufacturer of isolated soy protein and soy dietary fiber, processing 180,000 tons of soybeans per year with a production capacity of 50,000 tons of isolated soy protein annually.
Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd) manufactures our vital wheat gluten (30,000 tons per year), wheat starch, and technical-grade ethanol.
Guanxian Ruichang Trading Co., Ltd. acts as our dedicated in-house international trade company, streamlining customs, logistics, and documentation directly from the factory floors to your destination port.
We hold a comprehensive set of international food safety, quality, and religious certifications to support global importing requirements, including: HACCP, ISO9001, ISO22000, BRC (British Retail Consortium), HALAL, KOSHER, IP-NON GMO, and SGS audits. Other custom testing certificates and localized documentations can be generated at the client's request.
We operate our own dedicated, audited Non-GMO soybean planting bases. We run strict identity preservation (IP) systems across the entire supply chain. Every batch of soybean raw material undergoes PCR testing at reception. Processing lines are exclusively non-GMO to avoid cross-contamination, ensuring compliance with strict European and American import laws.
For meat processing (sausages, hot dogs, meat balls), we suggest 9001BW, 9007B-C, or 9500 (Meat & Emulsion Type) due to their excellent emulsion stability and high heat-induced gel strength. For instant powdered drinks or liquid beverages, we recommend 9030 or 9032 (Dispersion Type), which are optimized for rapid wetting, low viscosity, and clean taste profiles.
Our Isolated Soy Protein, Soy Dietary Fiber, and Vital Wheat Gluten products have a standard shelf life of 12 to 24 months from the date of manufacture when stored in their original unopened packaging (usually 20kg or 25kg multi-layer kraft paper bags with PE liners). They should be kept in dry, cool conditions below 25°C and under 60% relative humidity, away from strong odors and direct sunlight.
