An authoritative analysis of processing innovations, functional properties, supply chain compliance, and international B2B application strategies.
In the rapidly changing global food ingredient supply chain, Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd.) and its dedicated subsidiary Shandong Kawah Oils Co., Ltd., stand as the vanguard of high-purity agricultural protein extraction and processing. Established in 2007, Xinrui Industrial began with a visionary integration of wheat processing, which now handles more than 500,000 tons of wheat flour annually. Our integrated biorefinery model extracts high-value assets step-by-step: Vital Wheat Gluten, Wheat Starch A, and Wheat Starch B. The residual components, starch B and pentosan, feed directly into our advanced alcohol distillation process, closing the loop on agricultural waste and delivering a highly sustainable circular economy.
To expand our botanical protein footprint, Shandong Kawah Oils Co., Ltd. was established in 2014 with 120 million Yuan in registered capital. Operating as a leading agricultural industrialization group, Kawah Oils processes 180,000 tons of domestic Non-GMO soybeans every year. Through sophisticated, low-temperature, food-grade soybean extraction methods, we isolate high-purity soybean oil, low-temperature defatted meal, premium isolated soy protein, and natural soy dietary fiber. Today, our international trading arm, Guanxian Ruichang Trading Co., Ltd. (founded in 2011), directly distributes these essential inputs to over 60 countries, successfully merging manufacturing power with agile global logistics.
"The core competitive advantage of Xinrui Group lies in the complete control of the value chain. By sourcing Non-GMO raw materials from certified domestic cultivation bases and operating the largest single-line spray drying tower in China, we deliver high physical-chemical consistency across every batch of soy protein isolate."
Modern food formulation demands more than simple nutritional metrics; it requires deep functional reliability, absolute allergen trace control, and unquestionable identity preservation. For multi-national procurement teams, sourcing soy protein involves managing complex variables: non-GMO verification, consistent gelation strength, viscosity targets, and heavy metal limits.
Under Google’s E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) criteria, trust is established by physical control over processing environments. Our soybean processing facility features state-of-the-art spray drying systems from Dachuanyuan, securing the highest drying throughput and particle size consistency in China. This advanced setup prevents protein denaturation, guaranteeing that functional properties like water binding capacity (WBC), oil emulsification, and suspension stability are fully preserved for the end application.
Our factory offers customizable solutions tailored to the unique physical-chemical requirements of diverse food matrices. Below is our key product classification:
Engineered for high-shear emulsification systems. These isolates form a highly stable, heat-irreversible protein matrix that traps moisture and fat particles, preventing oil migration in canned foods, sausages, and meatballs.
Characterized by exceptionally low viscosity and rapid dispersion in brine systems. These isolates easily flow through delicate injection needles, ensuring even distribution throughout whole muscle meats and hams.
Specifically designed to replicate structural texture and mouthfeel. Perfect for traditional tofu production and plant-based meat analogues that require high tensile strength and elastic bite characteristics.
Refined for high dispersion profiles and neutral flavor, making them ideal for plant-based milks, nutritional powdered shakes, and dairy-free nutritional beverages. These types maintain stable suspension under various pH profiles.
Our Soy Dietary Fiber offers outstanding water-binding capacities to extend product freshness, while our Vital Wheat Gluten (pellets/powder) delivers high viscoelasticity, making it an essential texturizer for bakery and high-protein aquafeeds.
Integrating wheat starch and high-grade industrial/food ethanol. Our closed-loop system processes raw wheat down to secondary and tertiary raw materials, yielding a circular economy that lowers environmental impact and stabilizes costs.
The production of isolated soy protein relies heavily on precise separation technologies. At Shandong Kawah Oils, we implement a step-by-step extraction starting with low-temperature defatted meal. Soluble proteins are dissolved in alkaline solutions, separated from insoluble dietary fiber via advanced centrifugation, and subsequently precipitated at their isoelectric point (pH 4.5).
Similarly, our wheat gluten processing lines utilize premium, imported tri-canter centrifugal separation systems. This technology isolates starch A, starch B, and gluten proteins under entirely closed and hygienic operating conditions. By maintaining temperature-controlled processing throughout, we protect the fragile disulfide bonds in wheat gluten, yielding a final powder with excellent hydration kinetics and viscoelastic properties.
For modern food processors, botanical proteins are functional ingredients that solve real-world shelf-life and structural problems. In meat processing, our isolated soy proteins function as a primary emulsifier, helping control cooking loss and oil separation in hot dog lines. In plant-based meat analogues, they provide the structural basis for realistic fibrous muscle textures.
For global procurement directors, our integrated industrial model offers a reliable shield against supply chain disruptions. Because Guanxian Ruichang Trading controls both the manufacturing process and direct export operations, we bypass third-party trading markups. This ensures transparent cost structures, full batch traceability, and shorter lead times from our plant directly to your destination port.

Our commitment to sustainable processing, decarbonization, and next-generation nutritional engineering.
As global food demands shift toward plant-based alternatives, the nutritional value of plant proteins is undergoing scrutiny. Xinrui Group's R&D division is focused on improving the organoleptic qualities of soy proteins, reducing their natural beany flavor profile through advanced thermal processing and clean enzyme treatments.
Our roadmap includes upgrading our low-temperature soybean extraction systems to improve natural protein recovery rates while reducing energy consumption. Additionally, we are optimizing the heat recovery systems on our Dachuanyuan spray drying towers to decrease carbon emissions per ton of soy isolate produced. By combining sustainability with clean-label functionality, we ensure our global partners remain ahead of changing food regulations and environmental standards.
Clear, direct answers regarding capacities, logistics, compliance standards, and production processes.
We are a fully integrated group company named Xinrui Group, combining raw agricultural processing, chemical extraction, and international distribution. The manufacturer of our soy protein isolate is Shandong Kawah Oils Co., Ltd, which produces 50,000 tons of isolated soy protein per year. The manufacturer of our wheat gluten is Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd), producing 30,000 tons of vital wheat gluten annually. All international sales and export logistics are managed by our trading subsidiary, Guanxian Ruichang Trading Co., Ltd.
Our facilities are fully certified under HACCP, ISO9001, ISO22000, BRC (British Retail Consortium), HALAL, KOSHER, and IP-NON GMO. We work closely with international verification agencies like SGS to provide pre-shipment inspections, heavy metal testing, and microbiological certifications as required by the destination country's regulations.
Our plant processes 500,000 tons of wheat flour annually. The process isolates premium Vital Wheat Gluten and high-grade Wheat Starch A. The secondary wheat starch (Starch B) and pentosan are transferred directly to our fermentation facility to produce food and industrial-grade ethyl alcohol, as well as animal feed. This closed-loop system reduces waste, stabilizes production costs, and minimizes our environmental footprint.
The difference lies in their physical-chemical behaviors: Meat-type isolates (like 9001BH or 9007B-C) form high-strength, heat-irreversible gels under shear forces to retain water and fat. Injection-type isolates (like 9020) are processed for low viscosity and rapid dispersion in brine, preventing needle clogging during meat injection. Beverage-type isolates (like 9030 or 9032) are optimized to disperse quickly and remain suspended in liquid foods without settling out.
We maintain a strict Identity Preservation (IP) system from farm to final packaging. We source our raw materials exclusively from certified Non-GMO domestic soybean cultivation bases. Every incoming batch of soybeans undergoes rapid PCR testing at our warehouse gates. The raw material is processed on dedicated lines at Shandong Kawah Oils, with no risk of cross-contamination from GMO oilseeds.
