View Tech SpecificationsFounded in 2007 with a current registered capital of 100 million Yuan, Guanxian Xinrui Industrial Co., Ltd. (formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd) is a cornerstone of deep agricultural processing. Our facilities process 500,000 tons of premium wheat flour annually, utilizing cutting-edge three-phase decanter separation technology imported from Europe. This advanced closed-loop process ensures the extraction of highly purified wheat gluten and A/B starches under strict sanitary conditions, placing our production quality at the forefront of the global industry.
To provide a fully integrated soy-based protein ecosystem, our subsidiary, Shandong Kawah Oils Co., Ltd., was established in 2014 with 120 million Yuan in registered capital. Managing the deep-processing of 180,000 tons of strictly non-GMO domestic soybeans annually, Kawah Oils operates one of China's largest single-line spray-drying towers engineered by Dachuangyuan. This high-capacity system produces soy protein isolates, dietary fibers, and cold-pressed soybean oils that set international standards for dispersion, emulsification, and purity.
Our global operations are managed directly by Guanxian Ruichang Trading Co., Ltd. (established in 2011). Ruichang Trading bridges our advanced production lines with overseas manufacturers, exporting over 70% of the group's capacity directly to critical global hubs. Our specialized logistical pathways serving the Incheon Port and Seoul Capital Area ensure a secure, direct-from-factory supply chain.
Seoul is a major hub for plant-based food innovation in East Asia. Driven by the "K-Vegan" movement, clean-eating trends, and dairy-free lifestyles, leading food manufacturers in the Seoul Metropolitan Area (including Gyeonggi province) are reformulating traditional and modern food products. Isolated Soy Protein (ISP) is a critical raw material for structural texturization and emulsion stability.
Our non-GMO isolated soy proteins (such as the 9001BH and 9007B series) are engineered to meet this local demand. They provide functional elasticity and water-retention profiles ideal for premium tofu manufacturing, plant-based alternative meats (meatballs, visual muscle structures), and protein-fortified health drinks sold in Gangnam, Mapo, and Yeouido retail channels.
South Korea’s cosmetic capital, Seoul (Myeong-dong and corporate R&D laboratories in Pangyo), depends on ultra-pure solvents for formulation extraction, clean preservation, and sanitization. The market for edible and high-purity agricultural alcohol is tightly regulated, demanding raw materials with low odor profiles and strict chemical compliance.
By leveraging wheat starch processing streams, our biorefinery plant produces Wholesale Ethyl Alcohol Ethanol 95% & 96% Superior Grade. This ethanol features minimized volatile organic compounds (VOCs), making it ideal for the production of premium Korean herbal extractions, high-end cosmetic bases, organic sanitizers, and specialty beverage formulations. We provide local supply chain stability to Seoul-based trading entities and manufacturing plants.
Globally, the agricultural processing sector is transitioning to integrated circular systems to reduce waste and carbon footprints. Utilizing every stage of wheat processing—ranging from primary wheat gluten to high-quality starches, and converting byproduct pentosan fractions into high-value bio-ethanol—allows us to buffer against global raw material volatility and supply Seoul-based buyers with highly competitive pricing structures.
How our advanced manufacturing plants utilize physical separation and thermo-mechanical processing to yield highly functional proteins and pure distillates.
Our vital wheat gluten extraction process avoids chemical solvents, utilizing density-driven mechanical separation. This preserves the natural, elastic protein matrix of the wheat gluten, resulting in high water absorption and gas retention parameters.
Shandong Kawah Oils operates one of China's largest spray-drying facilities. Controlled pressure-nozzle configurations manage droplet size distribution, ensuring consistent particle size, fast dispersion, and low dust levels in our isolates.
To produce superior-grade ethyl alcohol, we run fermented biomass through continuous multi-stage rectification columns. The process removes heavy aldehydes, fusel oils, and esters to yield a highly neutral taste and low odor profile.
Every grade of isolated soy protein is physically modified to perform reliably in specific environments:
Requires 1:5:5 water-to-fat binding ratios. High-gel protein isolates (9007B-C) build resilient thermoreversible gels that lock in moisture and fat, preventing cook-shrinkage in processed seafood and cold cuts.
Requires clean flavor release and low grit. Ultra-dispersible grades (9030/9032) prevent sedimentation in oat milk blends, meal-replacement powders, and high-protein ready-to-drink (RTD) retail formats.
Adding Vital Wheat Gluten (VWG-P) to local flour formulations boosts the wet gluten index, which improves dough elasticity, controls breakage during processing, and enhances noodle chewiness.
