Premium functional isolated proteins engineered for water binding, emulsification, dispersion, and nutritional enrichment.
The global market for plant-based lean protein is undergoing a rapid, structural transformation. Driven by consumer awareness surrounding clean labels, sustainable production, and the functional superiority of plant-derived proteins, food manufacturers worldwide are seeking highly stable, clean, and non-GMO protein sources. Isolated Soy Protein (ISP) and Vital Wheat Gluten (VWG) stand at the forefront of this industrial shift, offering indispensable functional attributes like water absorption, emulsification, viscidity, and high nutritional density.
As a leading bulk manufacturer, Xinrui Group integrates agricultural sourcing, advanced physical wet-processing, and vertical downstream logistics. We supply high-grade lean protein ingredients to over 60 countries, addressing critical formulation challenges in meat processing, emulsified products, plant-based analogs, bakery goods, and low-viscosity beverages. Our state-of-the-art facilities ensure that global food brands access consistent particle sizes, optimal nitrogen solubility index (NSI), and high-purity non-GMO raw materials.
"Through continuous innovation in tri-canter separation and spray drying technologies, we have achieved a highly optimized manufacturing workflow that preserves protein integrity and nutritional bio-availability."
Our isolated soy protein is processed using exclusively domestic Non-GMO soybeans grown in dedicated, identity-preserved (IP) planting bases.
We utilize imported high-efficiency tri-canter centrifuge systems to isolate premium gluten fractions while preserving protein structure.
Our integrated model routes starch derivatives, pentosans, and processing wastewater back into clean energy and animal feed streams.
Tracing our foundation from May 2003, our corporate infrastructure spans over 1,000 mu, combining energy cogeneration, agriculture, and high-tech food manufacturing.
Originally established in 2007 as Guanxian Ruixiang Biotechnology Development Co., Ltd., Guanxian Xinrui Industrial Co., Ltd. has expanded its industrial processing capacity to mill over 500,000 tons of wheat flour annually. Through this facility, we produce high-grade wheat gluten, wheat starch A, and wheat starch B. To maximize resource efficiency, the pentosan and starch B are further utilized to produce high-grade bio-ethanol and premium animal feed. The core technology utilized in our wheat processing lines is the imported tri-canter separation method, providing a clean, completely closed-loop environment. Our capacity, machinery sophistication, and final product quality remain at the vanguard of the domestic industry.
Established in 2014 with a registered capital of 120 million yuan, Shandong Kawah Oils Co., Ltd. is a leading provincial agricultural industrialization enterprise. Kawah Oils operates a comprehensive system spanning agricultural cultivation, research and development, deep-processing, and export operations. Processing 180,000 tons of domestic non-GMO soybeans annually, Kawah Oils utilizes physical extraction processes to yield high-purity soybean oil, low-temperature food-grade soybean meal, isolated soy protein (with an annual output capacity of 50,000 tons), and dietary fiber.
Crucially, our isolated soy protein manufacturing uses the top-tier DACHUANYUAN spray drying tower. Featuring the largest single-line capacity in China, this setup ensures unmatched batch consistency, uniform thermal control, and pristine microbiological parameters, making our soy protein products perfect for sensitive pharmaceutical, beverage, and dairy applications.
Founded in 2011 to handle the group's global trade and logistics, Guanxian Ruichang Trading Co., Ltd. coordinates the distribution of isolated soy protein, wheat gluten, soluble dietary fiber, vermicelli, and superior grade ethanol directly to international B2B purchasers. With exports comprising over 70% of the group's production capacity, Ruichang Trading acts as the seamless bridge between advanced domestic manufacturing and global supply chains, providing localized regulatory compliance, customs clearance, and logistical tracking.
