As food systems shift toward clean label ingredients, resource-efficient proteins, and functional alternatives, Isolated Soy Protein (ISP) has emerged as a cornerstone of modern nutrition technology. Derived entirely from domestic Non-GMO soybeans, our production methods separate non-protein components to produce an isolate with a dry basis protein content exceeding 90%.
Understanding the molecular properties of soy globulins (specifically the 7S beta-conglycinin and 11S glycinin fractions) is critical to capturing the full value of ISP. The 11S globulin, structured with disulfide bonds, provides thermal stability and high gel strength, making it ideal for the meat processing sector. Meanwhile, the 7S globulin exhibits excellent emulsification capacity, essential for stabilize fat-water interfaces in plant-based dairy substitutes and liquid emulsions.
Through precise adjustments of pH and ionic strength during processing, our state-of-the-art facilities yield isolated soy proteins tailored to different application profiles, including high dispersion, emulsion stability, injection performance, and gel structure creation.
Our core production facility, operated under Shandong Kawah Oils Co., Ltd (established in 2014, registered capital of 120 million Yuan), processes over 180,000 tons of Non-GMO soybeans annually. We operate a highly integrated plant extraction model that converts raw Non-GMO soybean seeds step-by-step into high-value oils, low-temperature food-grade meal, isolated soy proteins, and dietary fiber.
Key to our quality control is the implementation of the DACHUANYUAN Spray Drying Tower. Featuring the largest single-line capacity in China, this system ensures quick moisture elimination, preventing thermal degradation and preserving the natural solubility, gelation, and water-binding capacity of the soy proteins.
Additionally, Guanxian Xinrui Industrial Co., Ltd (established in 2007, registered capital of 100 million Yuan) processes 500,000 tons of wheat flour annually. Our circular production chain employs advanced tri-canter separation technology to isolate high-purity vital wheat gluten and starch, utilizing starch B and pentosans for clean energy, steam generation, and animal feed. This vertical integration reduces the environmental footprint of our operations and ensures supply chain stability for our global clients.
We design and manufacture functional proteins for specific food industries. Use our technical matrix below to identify the most suitable protein isolate for your applications.
| Product Type & Target Grade | Key Functional Attribute | Primary Industrial Applications | Benefits & Performance Advantages |
|---|---|---|---|
| Chopping & Emulsion Type (9002B, 9001BW, 9500) | High Emulsification & Gelation | Sausages, Frankfurters, Meatballs, Burgers | Binds free fat and water to improve texture and sliceability, reducing cooking loss during thermal processing. |
| Meat & Injection Type (9020, 9026, 9028) | Low Viscosity & High Dispersion | Ham, Bacon, Whole Muscle Meat Injections | Dissolves quickly in brine, penetrates deep into meat fibers, and enhances texture and product yield. |
| Vegetarian & Tofu Type (9003B, 9005B) | High Gel Strength & Cohesion | Plant-based Meats, Vegetarian Tofu, Simulated Seafood | Forms a firm, elastic, and thermo-irreversible protein matrix that mimics animal protein fibers. |
| Dispersion & Beverage Type (9030, 9032) | Excellent Solubility & Low Viscosity | Protein Shakes, Ready-To-Drink (RTD) Beverages, Dairy Alternatives | Remains suspended in liquid systems across a range of pH levels, offering a smooth mouthfeel without grittiness. |
| Soy Dietary Fiber (SDF) | Water Absorption & Dietary Enrichment | Bakery Products, Nutritional Bars, High-Fiber Supplements | Increases water retention, improves shelf-life, and provides clean-label dietary fiber enrichment. |
| Vital Wheat Gluten (VWG-P / VWG-PS) | Viscoelastic Matrix Formation | Noodle Processing, Baking, Aquafeed Pellets | Provides structure, elasticity, and gas retention in dough, or serves as a water-stable binder in aquaculture feeds. |
We are refining enzymatic modification technologies to selectively break down allergen proteins and reduce off-flavors, delivering cleaner-tasting plant protein solutions.
Optimizing soy protein structures for twin-screw extrusion allows the development of plant-based meats with fibrous textures similar to beef and poultry.
Improving the functional attributes of Soy Dietary Fiber (SDF) to enhance yield and crumb structure in gluten-free baking applications.
Operating internationally requires strict compliance with food safety and identity preservation regulations. Our export operations are managed by Guanxian Ruichang Trading Co., Ltd (founded in 2011, registered capital of 6 million Yuan). By directing exports straight from our production plants, Ruichang manages over 70% of our group's output, offering international buyers direct pricing, secure logistics, and full traceability.
To support buyers in the Americas, Europe, and Asia-Pacific, we offer comprehensive compliance documentation, regional sales support, and specialized laboratory formulations to match local regulations.
Founded in 2003, Xinrui Group covers an area of more than 1,000 mu. The group is designed as a circular industrial ecosystem. It includes Guanxian Xinrui Industrial Co., Ltd, Shandong Kawah Oils Co., Ltd, regional cogeneration facilities (supplying urban heating and industrial steam), gas supply systems, and dedicated non-GMO soybean and wheat planting bases. Our integrated production structure generates over 2.8 billion Yuan in annual output value.
This scale ensures stable energy costs, continuous steam supply for processing towers, and independence from local power disruptions. For international buyers, this means reliable lead times, even during energy shortages.
