Explore our primary wholesale and high-emulsion isolated and concentrated soy protein lines tailored for global food manufacturing.
Established in May 2003, Xinrui Group spans a massive industrial area of more than 1,000 mu. Under its strategic umbrella, the group has developed a vertically integrated circular economy model that includes agricultural cultivation, advanced biotechnology processing, cogeneration energy, urban heating, and global supply systems.
Our state-of-the-art facilities process 180,000 tons of NON-GMO soybeans annually via our subsidiary, Shandong Kawah Oils Co., Ltd., alongside a massive wheat deep-processing division, Guanxian Xinrui Industrial Co., Ltd., which handles 500,000 tons of wheat flour per year.
In modern food industrial engineering, Soy Protein Concentrate (SPC) represents a critical ingredient category. Unlike native soy meals or crude flours, SPC is processed to contain a minimum of 65% to 70% protein on a dry weight basis by removing the soluble non-protein carbohydrates (primarily oligosaccharides like raffinose and stachyose). This concentration process eliminates flatulence-causing sugars and bitter beany off-flavors, delivering a highly digestible, functional protein module.
The physical-chemical attributes of high-quality SPC include exceptional water-holding capacity (WHC), superior fat-binding capabilities, and stabilizing emulsification networks. These molecular behaviors are vital for preventing syneresis (water loss) in processed meat products, ensuring uniform fat distribution, and providing structure in plant-based meat analogs.
Shandong Kawah Oils Co., Ltd. (established in 2014 with 120 million Yuan registered capital) operates as a leading enterprise in agricultural industrialization. Our factory integrates planting, research and development, processing, and global logistics. The raw materials used are sourced from our dedicated NON-GMO Soybean Planting Bases. Through advanced wet-extraction techniques, we process 180,000 tons of soybeans annually, extracting NON-GMO soybean oil, low-temperature food-grade soybean meal, isolated soy protein, and dietary fiber sequentially.
At the heart of our soy protein production line is the spray drying tower sourced from DACHUANYUAN, featuring a single-line production capacity that ranks as one of the largest in China. This system ensures high-efficiency water evaporation under controlled thermal conditions, preserving the protein's native globular state and preventing premature thermal denaturation.
This soy system works alongside Guanxian Xinrui Industrial’s wheat circular economy. By milling 500,000 tons of wheat per year, we extract vital wheat gluten, starch A, and starch B. Pentosan and starch B are fed directly into alcohol (ethanol) fermentation and animal feed production. This closed-loop design ensures maximum raw material valorization and reduces chemical waste to zero.
Global B2B food manufacturers face double-pronged pressures: maintaining reliable supply chains and verifying stringent non-GMO status. Buying directly from our integrated trade entity, Guanxian Ruichang Trading Co., Ltd. (established in 2011), allows enterprises to bypass intermediary margins. Over 70% of our group’s production capacity is exported directly to international markets, ensuring pricing transparency.
Our China-based supply chain capitalizes on the proximity of raw material cultivation in Shandong, direct energy input from our own cogeneration plants, and high-capacity maritime logistics through Qingdao port. This structural setup helps buffer overseas buyers against global raw material price fluctuations.
Different global food markets require targeted functional qualities. We customize our formulations across several specific profiles:
Reliability in global logistics requires strict certification compliance. Shandong Kawah Oils and Guanxian Xinrui maintain comprehensive quality systems verified by international bodies:
Our rigorous Identity Preservation (IP) system tracks each soybean batch from the field to the finished protein package, providing complete trace-back documentation. We also comply with ISO9001 and ISO22000, ensuring complete allergen management and microbiological control.
Comprehensive wheat and soy derivatives produced via our integrated circular processing factories.
