The global functional food landscape is undergoing a systemic transition. Wholesale food distributors, industrial processing plants, and international brand owners are increasingly demanding highly functional, allergen-safe, and sustainable plant-based proteins. As a premier wholesale vegan protein powder supplier and factory, Xinrui Group (including Shandong Kawah Oils Co., Ltd. and Guanxian Xinrui Industrial Co., Ltd.) is positioning its advanced processing capabilities at the forefront of this industrial revolution.
Our vertically integrated agricultural model ensures absolute quality control from seed to processing. By managing our wheat and non-GMO soybean planting bases, processing over 500,000 tons of wheat flour, and crushing 180,000 tons of non-GMO soybeans annually, we establish a secure, continuous, and highly efficient raw material stream. This robust control framework mitigates supply-chain vulnerabilities, providing raw ingredients that exceed global food safety standard thresholds.
Achieving superior functionality in vegan protein powders requires advanced extraction engineering. Rather than relying on standard thermal precipitation methods that denature proteins and ruin emulsification capabilities, Xinrui Group employs specialized technological pipelines:
For vital wheat gluten and wheat starch extraction, we imported state-of-the-art wet extraction tri-canter separation lines. This closed, fully automated circuit separates starch A, starch B, pentosans, and wheat gluten proteins under strict temperature-controlled settings. It maintains native protein molecular structures and preserves optimal viscoelastic properties.
Shandong Kawah Oils features the largest single-line spray-drying tower in China, engineered by Dachuanyuan. This technology utilizes short-exposure high-dispersion thermal airflow to dehydrate protein droplets instantly, yielding isolated soy protein powder with excellent dispersibility, solubility, and hydration metrics.
Our circular ecosystem runs on high-efficiency resource utilization. Byproducts such as starch B and pentosans are instantly funneled into ethanol distilleries or processed into high-nutrition animal feeds. Our co-located cogeneration plant supplies steam and electricity directly, lowering energy costs and carbon footprint.
Our comprehensive ingredient lineup is engineered for seamless integration across a wide range of localized and international application scenarios:
In food processing plants, managing the water-fat matrix is critical. Emulsion-type soy protein isolates (e.g., 9007B-C, 9007B-A, 9500, 9001BW) act as structural binders. When subjected to high shear during meat processing, these proteins create a stable emulsion network, preventing water separation and fat leakage during cooking. This improves chewiness and texture in sausages, burgers, and plant-based meat substitutes.
For structured and reformed meats, our chopping-type (9002B) and injection-type (9020/9026/9028) isolated soy proteins are ideal. The injection grades feature ultra-low viscosity under high-pressure flow, allowing them to penetrate deep into muscle tissues without blocking nozzles, resulting in juicier poultry and pork products.
RTD (Ready-To-Drink) vegan shakes and powder blends require high dispersibility and a neutral flavor profile. Dispersion-type isolates (9030/9032) are formulated to prevent sedimentation. Their high solubility across varying pH levels ensures a smooth mouthfeel without grittiness, providing clean labeling options for sports nutrition brands.
Traditional bean curd production demands controlled coagulation. Our tofu-grade isolates (9003B, 9005B) deliver high gel strength and excellent color uniformity, helping tofu manufacturers standardize production, increase yields, and extend shelf life.
Our Vital Wheat Gluten (VWG-P, VWG-PS) serves as a natural dough conditioner. By strengthening the gluten matrix, it improves gas retention, loaf volume, and crumb structure in bread, noodles, and high-protein bakery applications.
In today's complex supply chain environment, mitigating risks is essential for food brands. Guanxian Ruichang Trading Co., Ltd. serves as our group's dedicated export division, streamlining international trade operations:

Established in May 2003, Xinrui Group has grown into a diversified agricultural processing enterprise covering more than 1,000 mu. The group encompasses several specialized operational units, including Guanxian Xinrui Industrial Co., Ltd., Shandong Kawah Oils Co., Ltd., and Guanxian Ruichang Trading Co., Ltd. We operate a highly efficient circular economy industrial chain that links public cogeneration, municipal heating, gas utility services, and deep agricultural processing.
Our wheat processing facility, Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd., established in 2007 with 100 million Yuan registered capital), processes 500,000 tons of wheat flour annually. Utilizing advanced tri-canter separation systems, we produce high-grade vital wheat gluten, wheat starch A, wheat starch B, and pentosans, optimizing raw materials with minimal waste.
For non-GMO soy extraction, Shandong Kawah Oils Co., Ltd. (established in 2014 with 120 million Yuan registered capital) serves as our production hub, processing 180,000 tons of local non-GMO soybeans annually. We produce non-GMO soybean oil, low-temperature food-grade soybean meal, isolated soy protein, and dietary fiber. Our facility features China's largest single spray-drying line, built by Dachuanyuan.
Our facilities conform to international quality control systems. We hold comprehensive food safety and environmental certifications to ensure compliance in markets worldwide.
