Direct from our state-of-the-art facilities: Engineered with precise functional properties for emulsification, gelation, and dispersibility.
Driving the transition to healthy, functional, and sustainable plant-based food systems.
The global demand for plant-based proteins is undergoing a major paradigm shift. No longer limited to specialty nutritional products, functional ingredients like Isolated Soy Protein (ISP) and Soy Dietary Fiber (SDF) are now core elements of mainstream clean-label foods, processed meats, bakery items, and dairy-free formulations.
As food manufacturers optimize cost structures and seek stable clean-label functional alternatives, soy protein isolates have become essential. Thanks to their rich amino acid profile, high digestibility (PDCAAS = 1.0), and excellent water-binding and fat-emulsification properties, they are the functional base of choice for today’s food formulation scientists.
Xinrui Group supports global industrial buyers with a robust production network. Through integrated seed processing, extraction, spray drying, and international trade, we deliver reliable performance and high functional consistency across every batch.
A diversified agricultural industry group generating 2.8 billion RMB in annual output value.
Established in 2007 (formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd), our group features a fully circular agricultural economy processing model. Utilizing advanced tri-canter separation technology in our wheat processing lines, we maintain a clean and closed loop system. We process 500,000 tons of wheat flour annually, extracting high-purity wheat gluten and wheat starch (A and B grades), while converting starch B and pentosan into bio-ethanol and animal feed.
Established in 2014 with 120 million Yuan in registered capital, Shandong Kawah Oils is our dedicated soybean processing powerhouse. Handling 180,000 tons of domestic Non-GMO soybeans annually, Kawah Oils operates a complete, multi-step extraction system. The facility yields Non-GMO crude oil, food-grade low-temperature soybean meal, high-purity isolated soy protein (ISP), and soy dietary fiber. The heart of our production is the DACHUANYUAN spray drying tower, featuring the largest single-line processing capacity in China.
A closer look at the advanced chemical and physical properties that set our ingredients apart.
We modify the protein structure of our Isolated Soy Protein (ISP) to adjust its ratio of 7S (conglycinin) and 11S (glycinin) globulins. The 7S fraction provides excellent emulsification, while the 11S fraction delivers high gel strength. By balancing these globulins, we create specialized grades designed for specific industrial food applications.
For example, our 9001BW, 9001B-Y, and 9000 Meat & Emulsion types are engineered for strong fat-to-water binding. When processed at high shear rates, these proteins form a stable matrix that prevents fat separation and minimizes water purge during thermal sterilization.
Meanwhile, our 9020 Injection type is designed to keep viscosity low before injection, then form a strong, elastic gel during cooking. This makes it ideal for improving yield and texture in premium whole-muscle ham and poultry products.
| Product Type | Key Grades | Protein content (dry basis) | Primary Functional Traits | Target Food Applications |
|---|---|---|---|---|
| Isolated Soy Protein (Emulsion) | 9001BW, 9001B-Y, 9000, 9007B-A, 9007B-C, 9500 | ≥ 90% | High emulsification, robust heat-induced gel strength, excellent fat binding. | Frankfurters, sausages, canned meat products, vegetarian hot dogs. |
| Isolated Soy Protein (Injection) | 9020, 9026, 9028 | ≥ 90% | Ultra-low viscosity during processing, high dispersion, clean solubility. | Injected hams, poultry breasts, bacon, seafood preservation. |
| Isolated Soy Protein (Beverage) | 9030, 9032 | ≥ 90% | Acid-stable, high nitrogen solubility index (NSI), low beany flavor. | Nutrition powders, RTD plant-milk, sports drinks, infant formula. |
| Isolated Soy Protein (Vegetarian) | 9005B, 9003B | ≥ 90% | Fibrous structure formation, high water absorption. | Tofu, meat analogues, plant-based patties, structured burgers. |
| Soy Dietary Fiber | SDF-100, SDF-200 | ≥ 65% (TDF) | High water holding capacity, crumb texture improvement, clean label. | Bakery goods, high-fiber dietary snacks, processed meat extension. |
| Vital Wheat Gluten | VWG-P, VWG-PS (Pellets) | ≥ 75% | High viscoelasticity, gas retention, chewiness. | Bread baking, noodles, pet treats, aqua-feed binders. |
How our proteins perform in regional recipes and food processing lines around the world.
In high-speed processing lines across Europe and North America, our 9001BW and 9500 Emulsion type proteins act as secondary binders. They hold fat and water together in sausages and cold cuts during cooking, helping to maintain texture and reduce purge even when using automated high-speed packaging.
For meat processors aiming to increase yield by 30% to 50% without altering meat texture, our 9020 Injection Isolated Soy Protein disperses quickly in brines. It passes smoothly through fine needles without clogging, and gels inside the muscle fibers during pasteurization.
For meatless alternatives, our 9005B and 9003B proteins create the fibrous, chewy texture that consumers expect. When combined with our Soy Dietary Fiber, they lock in moisture to produce juicy, tender plant-based patties, nuggets, and tofu products.
Combining raw material security, green energy integration, and direct factory exports.
Our processing facility, Shandong Kawah Oils Co., Ltd., is situated in the heart of China’s major non-GMO soybean growing region. We source raw materials directly from local farming communities and our own dedicated planting bases. This close partnership guarantees a steady, traceable supply of high-purity, IP-certified non-GMO soybeans, insulating our production from volatile international grain markets.
Xinrui Group’s industrial park features a built-in cogeneration facility that generates heat, steam, and electricity. By producing our own energy, we reduce our carbon footprint and gain a reliable source of power. This setup protects our spray drying operations from external power outages and helps us maintain stable, competitive pricing for our global customers.
Founded in 2011, Guanxian Ruichang Trading Co., Ltd. is our group's dedicated export arm. Ruichang exports over 70% of our production volume directly to customers worldwide, including isolated soy protein, wheat gluten, and soluble dietary fiber. By handling our own logistics, we minimize intermediate fees, speed up customs clearance, and give our buyers real-time visibility into their shipments.
Every product batch is manufactured under strict international food safety standards.
We perform comprehensive physical, chemical, and microbiological testing on every production lot. From raw soybean inspection to the final packaging stage, we monitor for heavy metals, pesticide residues, and microbial activity to ensure our products meet or exceed the regulatory standards of the EU, FDA, and Asian markets.
