Explore our top-tier selection of industrial-grade Isolated Soy Proteins, Wheat Gluten, and functional dietary fibers designed for global food processing sectors.
Established in May 2003, Xinrui Group has cultivated a highly integrated, circular economy industrial network spanning over 1,000 mu. Driven by innovation, the group boasts an annual output value of 2.8 billion Yuan, successfully integrating agricultural biotechnology, municipal cogeneration energy, urban heating, and localized gas supply into one sustainable ecosystem.
Our primary manufacturing arms, Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd) and Shandong Kawah Oils Co., Ltd., operate state-of-the-art facilities processing 500,000 tons of wheat flour and 180,000 tons of soybeans annually. By cultivating our own domestic Non-GMO soybean and wheat planting bases, we guarantee complete supply chain traceability, setting the industry benchmark for plant protein processing globally.
Emulsion Isolated Soy Protein (ISP) is a highly functional macromolecule isolated from food-grade, defatted Non-GMO soybean meal. Structurally comprised of over 90% protein, its performance is dictated by the balance of two major globulins: glycinin (11S) and beta-conglycinin (7S). The 11S fraction, possessing multiple disulfide bonds, forms a rigid and heat-irreversible gel network. The 7S fraction, highly glycosylated, excels in molecular flexibility, allowing it to migrate rapidly to the oil-water interface to reduce interfacial tension.
Our emulsion-type Isolated Soy Proteins (such as models 9500, 9007B-A, and 9007B-C) are engineered to maximize these parameters. During processing, controlled enzymatic and thermal modifications expose the hydrophobic regions of the protein core. When sheared with water and lipids, these exposed hydrophobic sites bind oil droplets, while the hydrophilic regions project into the aqueous phase. This creates an extremely stable, viscoelastic emulsion matrix that survives thermal sterilization, mechanical cutting, and freeze-thaw cycles.
Exhibits exceptional water absorption capacities (up to 1:5.5 ratio), creating a firm protein gel network that locks in moisture and prevents fat syneresis during cooking.
Forces oil, water, and protein into a homogeneous suspension. Essential for minced meat products, maintaining structural integrity under high pasteurization heat.
Maintains texture and mouthfeel after high-shear industrial bowl cutters and ultra-high-temperature retort treatments, ideal for canned meats and sausages.
Different food applications require specific molecular properties. The table below outlines the primary industrial grades manufactured in our Shandong facilities to guide procurement teams in selecting the optimal protein matrix:
| Product Model | Primary Type | Emulsification Ratio (P:W:O) | Gel Strength (g/cm²) | Key Application Target |
|---|---|---|---|---|
| 9007B-A / 9007B-C | Meat & Emulsion Type | 1 : 5.0 : 5.0 | ≥ 350 | High-grade emulsified sausages, frankfurters, and meat cans. |
| 9500 / 9001BW | High-Gel Emulsion Type | 1 : 5.5 : 5.5 | ≥ 450 | Vegetarian meat analogues, premium hams, structured veggie steaks. |
| 9005B / 9003B | Tofu & Vegetarian Type | 1 : 4.5 : 4.0 | ≥ 300 | Traditional fresh tofu, freeze-dried tofu, and vegetarian snacks. |
| 9030 / 9032 | Beverage & Dispersion Type | Low viscosity dispersion | N/A | Nutritional powders, liquid dairy analogues, RTD beverages. |
Shandong is the global hub for non-GMO soy protein processing. Here is why our facility stands out in the competitive landscape.
Operating under Shandong Kawah Oils Co., Ltd., we utilize domestic Non-GMO soybeans as raw materials, extracting Non-GMO soybean oil, low-temperature food-grade meal, isolated soy protein, and dietary fiber in a continuous, closed-loop processing chain. Our manufacturing core features the spray drying tower from DACHUANYUAN, which represents the largest single production line capacity in China. This advanced facility enables a continuous output of 50,000 tons of isolated soy protein per year, guaranteeing stable physical properties across batches.
Additionally, Guanxian Xinrui Industrial Co., Ltd. processes 500,000 tons of wheat flour annually, utilising state-of-the-art tri-canter separation technology imported to refine wheat gluten, starch A, and starch B. This allows us to supply vital wheat gluten (30,000 tons/year) alongside soy proteins, providing a multi-functional botanical binder portfolio to global buyers.
By bypassing middle-tier trading agencies, our specialized exporter, Guanxian Ruichang Trading Co., Ltd. (founded in 2011 with a registered capital of 6 million Yuan), ships over 70% of our group's capacity directly to overseas food companies. This direct-from-factory export model ensures that cost savings are passed to procurement teams, while offering uncompromised communication on technical specifications, customized packaging, and regulatory documentation.
Our scale ensures reliable delivery of high-volume orders for global food producers, wholesalers, and distributors.
The global demand for plant-based ingredients is transitioning from a niche dietary trend to a core pillar of food industrialization. This transition is governed by three primary micro-trends:
Our Isolated Soy Protein portfolio is optimized for diverse food cultures and regional manufacturing standards:
For European frankfurters, Eastern European mortadella, and Latin American canned meats. The emulsion protein holds fat and water in a tight matrix, avoiding pocket formation during cooking.
For burgers, nuggets, and simulated seafood products. When combined with our vital wheat gluten, it recreates the fibrous, chewy texture of natural meat fibers.
For Asian markets. The 9005B and 9003B grades yield a smooth coagulation profile when treated with calcium sulfate or glucono-delta-lactone (GDL), producing firm tofu with high yield.
We adhere strictly to international quality control systems, guaranteeing that every shipment meets local food safety regulations.
