High-Quality Vegetarian Protein Powder Supplier & Factory

About Xinrui Group & Shandong Kawah Oils

Established in May 2003, Xinrui Group has grown into an industrial powerhouse covering a total area of more than 1,000 mu. Under its umbrella, the group integrates public cogeneration, urban heating, gas supply, and deep agricultural processing capabilities. Through decades of technological innovation, the group has founded Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd) and Shandong Kawah Oils Co., Ltd., establishing a fully traceble supply chain from wheat and Non-GMO soybean planting bases to final isolated proteins, dietary fibers, and functional starches.

Our export division, Guanxian Ruichang Trading Co., Ltd., established in 2011 with a registered capital of 6 million Yuan, handles direct export activities. It ensures over 60% to 70% of the group's massive plant-based protein output is shipped directly from the factory floor to overseas buyers, ensuring unmatched cost advantages, quality control, and transit times.

1. Technical Supremacy: The Infrastructure of China's Protein Manufacturing

The global demand for plant-based ingredients requires not only vast quantities but also absolute consistency in functional performance. As a premier vegetarian protein powder supplier and factory, our infrastructure represents the pinnacle of modern bio-refinement technology. At Guanxian Xinrui Industrial Co., Ltd., we process 500,000 tons of wheat flour annually. Our vital wheat gluten extraction employs advanced tri-canter separation technology imported from leading European suppliers. This completely closed and clean loop ensures starch A, starch B, pentosans, and gluten are separated with maximum purity, reducing environmental footprint and guaranteeing unmatched protein cohesion and elasticity.

For our soy protein isolation, Shandong Kawah Oils Co., Ltd. (established in 2014 with 120 million Yuan in registered capital) operates the largest single spray-drying production line in China. Our core system utilizes the internationally recognized Dachuanyuan spray drying tower. The precision-controlled evaporation and drying parameters maintain the natural protein structures of low-temperature food-grade soy meal. This level of process engineering preserves the gelation, emulsification, and water-binding properties necessary for advanced applications in the food industry.

2. The Circular Economy: Low Carbon Footprint and Cost Efficiency

In the modern agricultural sector, cost competitiveness and sustainability are interlinked. The Xinrui Group operates on a highly integrated circular economy model. By utilizing public cogeneration (combined heat and power generation), our facilities share energy inputs. The steam generated from our power stations drives the spray drying towers for soy protein and the tri-canter separators for wheat starch. This thermal integration lowers production costs compared to isolated factories that rely on municipal energy grids.

Furthermore, our material streams are circular. When we process wheat flour, the high-purity Wheat Starch A and Vital Wheat Gluten are separated. The secondary streams, Wheat Starch B and pentosans, are diverted into our integrated ethanol plants to produce superior-grade 95% and 96% ethyl alcohol and high-value animal feed. By converting potential waste into valuable co-products, we optimize yield, eliminate disposal costs, and reduce the overall carbon footprint of our plant proteins.

3. Global Sourcing Dynamics: Meeting International Regulatory and Technical Standards

B2B procurement of plant-based proteins requires strict adherence to international regulatory frameworks. Global food brands and pharmaceutical manufacturers demand verified quality systems. Xinrui Group addresses these requirements through our comprehensive testing protocols and certifications. We have established complete traceability systems to verify that our raw materials remain untainted by GMO strains, matching IP Non-GMO standards.

Our production facilities operate under ISO 9001 and ISO 22000 food safety management programs. In addition, we maintain HACCP controls, BRC (British Retail Consortium) certification, and religious dietary compliance including HALAL and KOSHER. These qualifications ensure our isolated soy proteins, vital wheat gluten, and soluble dietary fibers enter international markets without regulatory friction.

4. Application-Driven Product Engineering

Rather than providing a one-size-fits-all protein powder, our factory engineers plant proteins for specific food matrix applications:

• Emulsification and Meat Systems (9001BW / 9007B-C / 9500): Engineered with high solubility and dispersibility, these isolated soy proteins bind water and oil molecules in a stable matrix. This prevents fat migration and water syneresis during cooking, which is critical for emulsified sausages, hot dogs, and canned meats.
• Injection & Chopping Systems (9020 / 9002B): Formulated with low viscosity under high shear, these proteins flow through fine injection needles without clogging. They hydrate within muscle fibers, improving yield and tenderness in whole-muscle hams and poultry products.
• Beverage and Dispersion Systems (9030 / 9032): Designed to dissolve quickly at neutral pH, these powders display low sedimentation and low astringency. They are suitable for ready-to-drink (RTD) plant milks, meal replacement shakes, and functional nutritional mixes.
• Tofu & Vegetarian Systems (9003B / 9005B): These isolate grades are optimized for cohesive, firm curd formation under thermal treatment. They form the structural backbone of traditional tofu, sheet tofu, and textured vegetarian foods.
