Select from our key industrial plant-based proteins and food additives engineered to enhance emulsification, water binding, and nutritional profiles.
In the contemporary global food manufacturing sector, ingredients are no longer viewed merely as bulk inputs, but as functional pillars that define the texture, structural integrity, and clean-label compliance of commercial foods. The shift towards plant-based diets, coupled with the optimization of manufacturing efficiency, has placed high-quality plant proteins—specifically Isolated Soy Protein (ISP) and Vital Wheat Gluten (VWG)—at the core of technical food science innovations.
As standard-setting suppliers, factories must demonstrate not only volume scale but deep-tier molecular expertise. Food ingredients undergo complex thermodynamic and mechanical processing, requiring strict controls over parameters such as the Nitrogen Solubility Index (NSI), gelling temperatures, and shear resistance. This whitepaper analyzes the key technical factors determining functional efficiency, crop processing traceability, and global supply configurations required by Tier-1 food processors.
Evaluating soy and wheat protein behaviors under temperature, pH shifts, and mechanical shear. Optimizing amino acid ratios and protein structures to match exact formulation targets.
Deploying strict Identity Preservation (IP) systems across the entire supply chain. Total protection from GMO crossover from seed and cultivation to refining towers.
Direct factory delivery combined with integrated trade infrastructure. Providing bulk maritime supply chains and localized compliance pipelines for global partners.
Established in May 2003, Xinrui Group represents a highly integrated industrial organization covering an area of more than 1,000 mu. Driven by a mission of sustainable agriculture and modern circular economy principles, the group has developed a robust circular industry chain that connects raw material farming, steam/power cogeneration, urban heating, gas supply, and deep agricultural processing.
Today, the group boasts an annual output value of 2.8 billion Yuan, powered by two massive primary refining divisions: Guanxian Xinrui Industrial Co., Ltd. (flour processing and wheat derivatives) and Shandong Kawah Oils Co., Ltd. (soybean processing and protein isolation). The export operations are managed by Guanxian Ruichang Trading Co., Ltd., facilitating high-speed shipping directly to global hubs.
Under Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd), established in 2007 with a registered capital of 100 million Yuan, we have integrated the world's most advanced wet extraction systems: the **Tri-Canter separation technology** for vital wheat gluten and starch processing. Unlike legacy systems, this closed-loop, highly clean, automated production line separates wheat starch A, wheat starch B, and vital wheat gluten with zero waste discharge.
Byproducts of this refining cycle, including starch B and pentosans, are directly routed into our bio-ethanol and animal feed facilities, creating a true waste-free circular industrial model. Our technical capabilities, safety equipment, and final product purity lead the industry nationally.
Established in 2014 with a registered capital of 120 million Yuan, Shandong Kawah Oils Co., Ltd. is a leading provincial agricultural industrialization enterprise. The facility processes 180,000 tons of domestic Non-GMO Soybeans annually, utilizing a vertical extraction model that yields high-purity soybean oil, low-temperature food-grade soybean meal, isolated soy protein (ISP), and dietary fiber.
Our core advantage lies in our state-of-the-art spray drying system. We operate the premier DACHUANYUAN spray drying tower, featuring the largest single-line drying capacity in China. This advanced engineering ensures uniform particle sizes, excellent solubility, and pristine color profiles, preventing denaturation during the final thermal stages of isolation.
To support global supply stability, Kawah Oils owns and manages dedicated Wheat & Non-GMO Soybean Planting Bases. This ensures full traceability and strict agricultural control from the seed onward. Once processed, our ingredients are directly managed for global delivery by Guanxian Ruichang Trading Co., Ltd. (founded in 2011, 6 million Yuan registered capital).
Ruichang Trading exports isolated soy protein, vital wheat gluten, soluble dietary fiber, vermicelli, and superior grade ethanol directly from our factories to global partners, with the export ratio exceeding 70% of the group's total production capacity. This integration guarantees consistent pricing and eliminates middleman margins.
Our functional proteins and dietary fibers are designed for specific chemical interactions within food systems, guaranteeing premium texture and consistency.
Our Isolated Soy Protein products (purity >90% on dry basis) are extracted from domestic non-GMO soybeans using advanced acid-precipitation and neutral-dissolution processes. They are categorized based on functional parameters:
Extracted from high-quality wheat using our closed-loop tri-canter technology, our Vital Wheat Gluten provides exceptional viscoelasticity, cohesion, and structural integrity. Available in two main formats:
Constructed from non-GMO soy cell-wall structures, our Soy Dietary Fiber combines high water-binding capacity (up to 1:10) with excellent oil absorption. It improves yields and extends shelf life in bakery goods while enhancing digestive health profiles.
Analyzing the strategic advantages of China's agricultural manufacturing hubs and localized market adaptation protocols.
We work directly with regional regulatory bodies across the EU, North America, LATAM, and the Asia-Pacific region. Our team provides specialized document packages (COA, Allergen Statements, Non-GMO declarations, and Heavy Metal reports) to ensure fast customs clearance and regulatory alignment with FDA, EFSA, and local standards.
Operating in Guanxian, Shandong, we benefit from vertical integration. Our self-managed power and heating cogeneration plants shield our production processes from energy market fluctuations. Our close proximity to Qingdao Port allows us to provide cost-effective freight shipping, maintaining competitive pricing for high-volume orders.
We do not just supply raw powders; we deliver solutions. Kawah Oils and Xinrui Industrial operate advanced R&D application labs. We work directly with food manufacturers to customize gel strength, viscosity, dispersion rates, and protein levels, matching the unique target parameters of your specific production lines.
Food safety is at the core of our business. Our production processes conform to international quality management systems. Our facilities are regularly audited by third-party verification bodies, ensuring that every batch of isolated soy protein and vital wheat gluten meets strict safety standards.
We hold verified certificates including HACCP, ISO9001, ISO22000, BRC (BRCGS), HALAL, KOSHER, IP-NON GMO, and SGS. This comprehensive certification suite allows our products to integrate smoothly into high-standard food processing plants worldwide.
