A comprehensive overview of how Isolated Soy Protein (ISP) acts as the ultimate structural building block for modern meat analogs.
Replicating the complex texture, mouthfeel, and moisture-holding capacity of animal muscle fibers remains one of the largest hurdles in food science today. Ordinary protein powders fail to match the fibrous structure of cooked meat, leading to mushy textures or dry crumbly bites. Isolated Soy Protein (ISP) solves this by presenting a minimum of 90% dry-basis protein content with functional molecular chains optimized for cross-linking.
Through precise thermal-induced gelation and high shear tolerance, our ISP grades form stable gel matrices that lock in fat and moisture. Whether utilized in high-moisture extrusion (HME) processes, emulsified vegetarian sausages, or restructured meat formulations, our solutions mimic the elastic, resilient texture that global consumers demand.
Leveraging deep industrial scale and zero-waste ecosystems to supply resilient protein solutions globally.
Founded in 2007, Guanxian Xinrui Industrial Co., Ltd. (formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd) operates on a registered capital of 100 million Yuan. We process 500,000 tons of wheat flour annually, extracting vital wheat gluten, wheat starch A, and wheat starch B. The downstream residual starch B and pentosan are recycled directly into producing premium ethanol and sustainable animal feed.
Our sister enterprise, Shandong Kawah Oils Co., Ltd., established in 2014 with 120 million Yuan of registered capital, processes 180,000 tons of domestically grown, IP-certified non-GMO soybeans annually. From agricultural plantation management to extraction, spray drying, and international trade via Guanxian Ruichang Trading Co., Ltd., the Xinrui Group represents a diversified industrial ecosystem generating 2.8 billion Yuan in annual output.
How the molecular configuration of Shandong Kawah Oils' ISP guarantees superior gelation, emulsification, and injection performance.
Our ISP undergoes a precise heat denaturation process, opening the globulin chains to facilitate rapid cross-linking. When cooked, this creates a resilient 3D gel network that mimics animal muscle behavior, providing a satisfying bite and chewiness.
By balancing hydrophobic and hydrophilic amino acid sites on the protein chain, our emulsion-type ISPs (9007B-A, 9007B-C, 9500) wrap oil droplets securely. This prevents oil separation during high-temperature canning or chopping, maintaining juicy mouthfeel.
Designed specifically for ham and whole-muscle meat processing, our Injection ISP (9020) exhibits highly dispersed, low-viscosity behavior in brine solutions. It passes through fine injection needles without clogging, binding water inside the meat matrix upon thermal pasteurization.
| ISP Grade Code | Primary Functional Type | Key Application Field | Water Binding / Emulsification Ratio |
|---|---|---|---|
| 9002B / 9001BH / 9006B | Chopping & Meat Type | Meatballs, Quick-frozen Fillings, Frankfurters | 1:5:5 (Protein : Water : Oil) |
| 9007B-A / 9007B-C / 9500 | Meat & Emulsion Type | Emulsified Sausages, Canned Meats, Deli Slices | 1:5.5:5.5 (High Emulsion Stability) |
| 9020 / 9026 / 9028 | Injection Type | Hams, Whole Muscle Poultry, Seafood Treatment | High Dispersion, Low Viscosity at Cold State |
| 9003B / 9005B | Tofu & Vegetarian Type | Traditional Tofu, Meat Analogs, High-protein Foods | Firm Gel Strength & Neutral Taste Profile |
| 9030 / 9032 | Beverage & Dispersion | Protein Drinks, Dairy Alternatives, Dry Blends | Ultra-High Solubility & Low Viscosity |
Inside our state-of-the-art facilities utilizing advanced spray drying technology to guarantee batch-to-batch consistency.
Temperature fluctuations and uneven drying are the primary causes of variable gel strength in soy protein isolates. At Shandong Kawah Oils, we have deployed the DACHUANYUAN spray drying tower, featuring the largest single-line processing capacity in China. This advanced engineering system uses ultra-fine atomization and precise computer-controlled hot air profiles to ensure that each protein particle is dried uniformly.
Furthermore, our wheat protein processing relies on imported tri-canter separation technology. This creates a fully closed, clean-in-place (CIP) line that keeps the wheat starch and vital wheat gluten free from environmental contaminants. This integration not only reduces biological risk factors but also lowers utility consumption, keeping our pricing highly competitive.
How we help multinational food manufacturers manage risk, optimize formulations, and achieve sustainability targets.
With our localized planting bases, we guarantee a closed identity preserved (IP) system from the seed to final packaging. Rigorous testing checks for GM traits at multiple stages, shielding your brand from regulatory non-compliance.
By producing both Isolated Soy Protein and Vital Wheat Gluten (VWG-P/VWG-PS) under one corporate group, we offer blended systems that create realistic, pull-apart fibrous textures in vegan chicken nuggets, steaks, and burgers.
Guanxian Ruichang Trading Co., Ltd. handles 70% of the group's output for direct export. By bypassing intermediaries, global purchasers gain direct factory pricing, rapid lead times, and comprehensive document clearance support.
Our commitment to food safety is verified by the world's most rigorous third-party auditing schemes.
Xinrui Group operates on the core belief that international food trade demands strict adherence to tracebility and sanitation. Our production lines comply with BRC Global Standards for Food Safety, and we implement a robust HACCP hazard analysis protocol throughout the factory floors.
Our clean-label soy protein isolates and vital wheat gluten are fully certified Halal and Kosher, ensuring suitability for diverse consumer groups. We also cooperate with world-recognized inspection agencies like SGS to run regular audits and product testing on chemical purity, microbiological profiles, and allergen controls.

We are a vertically integrated group company named Xinrui Group. The manufacturer of our Isolated Soy Protein is Shandong Kawah Oils Co., Ltd., producing 50,000 tons per year. The vital wheat gluten is manufactured by Guanxian Xinrui Industrial Co., Ltd., producing 30,000 tons per year. The direct exporter representing the group for international clients is Guanxian Ruichang Trading Co., Ltd.
We hold certifications including HACCP, ISO9001, ISO22000, BRC (Global Standard for Food Safety), HALAL, KOSHER, IP-NON GMO, and SGS. Other chemical or structural certificates can be provided upon customer request.
Domestically grown Chinese soybeans are historically non-GMO (Identity Preserved). Compared to massive bulk import varieties, they possess a higher protein-to-fat ratio and lack genetically modified herbicide resistance traits. This allows for cleaner labeling and conforms strictly to European Union (EFSA) import requirements.
Our circular model connects wheat processing and soybean processing. Byproducts from one stream, such as low-grade starch, are directly utilized to generate industrial-grade ethanol and steam power. This vertical integration keeps energy costs low and enables us to pass these cost-efficiencies down to global food brands.
