Direct supply of functional proteins, fibers, and starches from China's largest single-line industrial processing cluster.
The global food industry is experiencing an unprecedented structural transition driven by plant-based dietary shifts, clean label initiatives, and functional performance expectations. Isolated Soy Protein (ISP), with a minimum protein concentration of 90% on a dry basis, sits at the absolute core of this transformation. As food processors design meat analogs, nutritional beverages, and high-emulsion cold-cut matrices, the requirement for highly specific, functional, and clean-tasting protein isolates is expanding exponentially.
However, the global protein supply chain is plagued by systemic issues: volatile pricing, fluctuating gel strengths, GMO contamination risks, and high carbon footprints. Today's procurement directors are no longer simply looking for bulk raw materials; they demand engineered food matrices that guarantee high emulsion capabilities, excellent solubility profiles, and rigorous non-GMO identity preservation (IP). This is where advanced industrial systems and circular manufacturing loops provide a decisive advantage.
Critical Factor: To achieve reliable emulsion stability, the modern food formulation process demands isolated soy proteins with high gel strength, specific viscosity levels, and zero beany flavor profile. Our production lines are specifically tuned to address these physical-chemical requirements.
How we leverage closed-loop manufacturing and advanced extraction systems to deliver unmatched cost efficiency and product consistency.
Founded in 2003, Xinrui Group spans over 1,000 mu, uniting diverse industrial plants to form a unified circular economy model. Our operational efficiency is built upon deep raw material utilization: processing 500,000 tons of wheat flour annually to extract premium vital wheat gluten and starch, and routing by-products into high-grade ethanol and animal feed. This minimizes environmental impact while maximizing yield per ton of grain.
Our dedicated subsidiary, Shondong Kawah Oils Co., Ltd (established in 2014), handles our non-GMO soybean processing. Extracting edible soybean meal, soy protein isolate, and dietary fiber under strict quality controls, the plant represents China's leading agricultural scale. We control the supply chain from our dedicated planting bases straight to the final spray-drying towers.
The core of our soybean isolate facility is the state-of-the-art spray drying tower system sourced from DACHUANYUAN, featuring one of the largest single-line capacities in China. This configuration enables us to achieve ultra-fine powder particles, high solubility index, and excellent heat dispersion, preventing thermal damage to critical protein structures.
In our wheat processing lines (Guanxian Xinrui Industrial Co., Ltd.), we utilize imported tri-canter separation systems. This closed-loop technology extracts premium wheat gluten powder and pellets with exceptionally clean protein fractions. With integrated logistics managed by Guanxian Ruichang Trading Co., Ltd., we export more than 70% of our capacity to over 50 countries, facilitating seamless industrial and trade integration.
We engineer distinct functional categories of Isolated Soy Protein to resolve specific formulation issues in varied global food applications.
Designed for emulsified sausages, frankfurters, and cold cuts. Excellent water-binding and fat-holding capacity. Maintains structure during thermal processing and reduces purge loss.
Perfect for plant-based burgers, nuggets, and traditional vegetarian tofu matrices. Provides structural chewiness and realistic bite texture mimicking animal muscle fibers.
Engineered for high solubility, low viscosity, and clean sensory properties. Dissolves rapidly in liquid formulations without chalkiness, suitable for meal replacement shakes.
Extremely low viscosity combined with zero particulate settling. Easily injected directly into whole-muscle meats like hams and bacon to improve juiciness and yield.
An excellent natural water-binder and structural enhancer. Boosts dietary fiber content in baked goods and meat preparations while maintaining moisture retention.
Leveraging our wheat processing cluster to provide high-elasticity wheat gluten pellets and powder, alongside premium binding starches for bakery applications.
