Highly functional isolated soy proteins, wheat gluten, and starch compounds manufactured under absolute quality controls.
Food-grade Isolated Soy Protein (ISP) represents the apex of modern plant protein refining technology. Derived from 100% Non-GMO soybeans through sophisticated chemical and structural extraction processes, ISP features a protein dry-matter content exceeding 90%. By stripping away the soluble carbohydrates, oligosaccharides, fats, and crude fiber, the resulting protein matrix delivers unparalleled emulsification, water absorption, gelation, and dispersibility attributes.
The manufacturing architecture deployed across the production facilities of Shandong Kawah Oils Co., Ltd. preserves the natural state of these functional proteins. Our extraction plants utilize low-temperature defatted soybean meal, isolating the crucial 7S (beta-conglycinin) and 11S (glycinin) globulins that govern texturizing characteristics. This deliberate extraction method guarantees exceptional gel strength and structural integrity, satisfying the rigorous physical requirements of complex global processed food formulations.

Discover how our specialized isolated soy protein grades adapt to demanding production environments and regional preferences.
Specifically designed for sausages, hot dogs, and meatballs, our 9007B-C and 9001BW grades create resilient protein matrices. They bind moisture and encapsulate fat droplets, mitigating cook-shrinkage and securing stable shelf-life across temperature fluctuations.
Addressing the surging demand for plant-based nutrition, our 9003BA and 9005B grades optimize the structural elasticity of vegetarian meats, traditional tofu, and vegan analogues. They mimic the bite profile and chewiness of animal proteins.
For instant energy blends, infant formulas, and protein waters, our 9030 and 9032 dispersion isolates offer low-viscosity, high-dispersibility, and low-dust profiles, avoiding sedimentation in liquid systems.
In whole-muscle poultry and meat processing, using standard proteins can clog injection needles. To resolve this, we engineered our 9020/9026/9028 injection-type isolates. These formulations disperse immediately, migrating through muscle fibrils to enhance cooking yields and ensure uniform texture.
Pioneering tomorrow's sustainable protein isolation technologies through research and strategic manufacturing upgrades.
Our commitment to technical excellence is rooted in ongoing engineering investments. Shandong Kawah Oils Co., Ltd. operates the largest single-line spray drying tower in China, engineered by DACHUANYUAN. This system features specialized temperature zones, preventing protein denaturation and ensuring uniform particle morphology.
Our wheat processing division, Guanxian Xinrui Industrial Co., Ltd., implements advanced tri-canter separation technology for wheat gluten production. This process minimizes raw water consumption and protects the native, viscoelastic properties of the gluten structure, separating starches A and B cleanly.
Looking ahead, our technical roadmap centers on two initiatives: zero-carbon production facilities utilizing our own cogeneration energy loops, and chemical-free enzyme modification. By adjusting enzymatic treatments, we are tailoring our protein isolates to have specialized molecular weights. This allows us to customize protein behavior for specific food matrices, from low-fat spreads to dairy alternatives.
Optimizing resource loops to stabilize costs and maintain consistent raw material supply for international buyers.
Founded in May 2003, Xinrui Group spans over 1,000 mu, anchoring a model of agricultural industrialization. Our circular system integrates raw material sourcing, processing, energy generation, and environmental management, insulating our operations from external market disruptions.
Guanxian Xinrui Industrial Co., Ltd. processes 500,000 tons of wheat flour annually. This process extracts wheat gluten and high-grade wheat starch A, while starch B and pentosan are funneled into ethanol fermentation. Our group's cogeneration plant provides urban heating, gas supply, and the process steam needed for our spray towers. This setup lowers energy overheads and guarantees production uptime during seasonal energy shortages.
Shandong Kawah Oils Co., Ltd., established in 2014 with 120 million Yuan in registered capital, processes 180,000 tons of local Non-GMO soybeans each year. This step-by-step extraction process yields Non-GMO oil, low-temperature soy meal, isolated soy protein, and dietary fiber, capturing value at every stage of production.

Exporting to food processors worldwide requires precise regulatory compliance and raw material traceability. Through Guanxian Ruichang Trading Co., Ltd. (our integrated import and export division founded in 2011), we ship over 70% of our production volume directly to overseas markets. Our export logistics leverage rigorous Identity Preservation (IP) protocols, ensuring that our Non-GMO soybean supply chain remains segregated and untainted from cultivation through to packaging.
This comprehensive tracking program is paired with strict third-party analysis. Every batch of isolated soy protein is tested for genetically modified DNA traces, pesticide residues, and heavy metals. This documentation matches the requirements of major international customs borders, supporting smooth port clearance and reliable production scheduling for our clients.
Verified by globally recognized auditing bodies to meet strict safety, dietary, and quality standards.
