Explore our industrial-grade isolated soy proteins, vital wheat glutens, and specialized plant derivatives optimized for food systems.
The global food manufacturing landscape is undergoing a critical transition. Food processors, industrial manufacturers, and vegan food developers are demanding ingredients that possess not only clean-label characteristics but also superior physical functionalities. High gel isolated soy protein represents the zenith of this functional performance, offering exceptional water-binding, oil-emulsifying, and structural elasticity parameters.
Xinrui Group, through its advanced plant extraction arm Shandong Kawah Oils Co., Ltd., delivers a high-gel isolated soy protein solution engineered to exceed structural requirements across cold-form, retort, injection, and extrusion settings. Using 100% domestic non-GMO soybeans, we manage the entire value chain—from seed pedigree monitoring to multi-phase spray drying operations—ensuring a minimum protein concentration of 90% (dry basis) with unparalleled batch-to-batch structural uniformity.
A technical examination of how isolated soy protein creates dense, robust polymeric networks.
High-gel isolated soy protein derives its functional excellence from the precise denaturation and reorganization of 7S (conglycinin) and 11S (glycinin) globulins. The 11S globulin, characterized by its disulfide-rich quaternary structure, is the primary driver of gel strength under thermal conditions. When exposed to heat, these proteins unfold, exposing hydrophobic zones that subsequently cross-link to form an intricate, three-dimensional macromolecular structure that traps water and lipids.
For emulsified meat networks, vegetarian patties, and seafood analogues, the stability of this matrix is critical. A standard gel strength rating exceeding 200g/cm² to 350g/cm² ensures that during mechanical slicing, high-temperature retorting, or freezing, the cellular structure of the food remains intact without synaeresis (water weepage) or lipid separation.
Our processing methodologies leverage the DACHUANYUAN spray drying tower system—the largest single-line spray drying tower in China. This configuration enables precise control over particle thermal exposure and shear speed, maintaining the raw protein's functional integrity. As a result, our proteins feature a highly soluble profile that rapidly hydrates to create a cohesive network, enabling cost-efficient formulas with high water-to-protein ratios.
How our vertical processing operations minimize risk and deliver cost efficiencies.
Xinrui Group operates on a circular economy paradigm. Established in 2003 and covering more than 1,000 mu, our group links agriculture, thermal power generation, municipal utilities, and deep agricultural processing. Under our integrated model, wheat and soybean processing feed back into circular energy loops, lowering production costs and guaranteeing consistent utilities supply during peak periods.
Our raw material supply chain relies on designated Non-GMO soybean planting bases in China. Shandong Kawah Oils Co., Ltd., processes 180,000 tons of soybeans annually, extracting non-GMO soy oil, low-temperature food-grade meal, isolated soy protein, and soy dietary fiber sequentially. Because we process the base seeds and low-temperature meal in-house, we control raw material freshness and protect the protein structures from heat damage before isolation.
Our wheat milling operation processes 500,000 tons of wheat flour annually, utilizing advanced tri-canter separation technology imported for vital wheat gluten and starch production. This closed-loop design ensures that all side-streams, including starch and pentosans, are directed to animal feed and industrial ethanol production, reducing waste and generating cost savings that we pass along to our partners.
Engineered to deliver performance, clean-label characteristics, and stability across demanding industrial environments.
Binds oil and water in a stable 1:5:5 matrix, preventing fat separation and ensuring a firm bite in cooked, canned, or fresh sausage formulations.
Maintains its physical gel strength under retort sterilization processes (exceeding 121°C), making it ideal for canned food formulations.
Processed with advanced deodorization systems to yield a clean flavor profile, minimizing beany off-notes and reducing flavor-masking costs.
Emulsified Sausages & Frankfurters: Adding our high-gel soy protein isolate to sausage blends creates a firm texture and stabilizes meat emulsions. It reduces purge loss during refrigeration and preserves succulence in pre-sliced cold cuts.
Vegetarian Products & Plant-Based Meat: For meat alternatives requiring a fibrous texture, our high-gel isolate acts as a structural adhesive. When combined with vital wheat gluten, it replicates the natural chew and resilience of muscle fibers.
Structured Tofu & Vegetarian Surimi: Varieties like our 9003B and 9005B isolated proteins are specifically designed for hydration stability and quick set speeds, producing a smooth, elastic tofu with reduced water loss.
Injected Meat Whole Cuts: Our dispersible grades (such as the 9020/9026/9028 series) are tailored for brine systems. They dissolve without clogging injection nozzles, distributing evenly to enhance yield and tenderness in whole-muscle hams and poultry products.
Our manufacturing sites operate under international quality assurance programs to support seamless global distribution.
We recognize that global food manufacturers require strict safety documentation and traceability. Shandong Kawah Oils Co., Ltd., and Guanxian Xinrui Industrial Co., Ltd., undergo regular third-party audits to maintain compliance with strict food contact and biological safety standards across major global regions.
Guanxian Ruichang Trading Co., Ltd. (the export branch of Xinrui Group) ensures direct shipment and efficient Customs clearance worldwide.
To streamline global supply chains, we established Guanxian Ruichang Trading Co., Ltd. in 2011 with a registered capital of 6 million Yuan. Operating as the direct exporting arm of Xinrui Group, Ruichang manages more than 70% of our factories' total output capacity, shipping products to buyers in Europe, the Americas, Southeast Asia, and the Middle East.
By integrating manufacturing with trade, we offer direct factory-to-port logistics, flexible container consolidation, customized pallet configurations, and container moisture protection. Whether you are procuring isolated soy protein, soy dietary fiber, vital wheat gluten, or food-grade ethanol, our export team manages the necessary health certificates, non-GMO identity preservation (IP) validations, and shipping schedules to minimize port delays.
