High-performance functional protein matrixes designed for meat chopping, emulsification, and water-binding capacity
Scale, integration, and infrastructure driving global competitiveness
Isolated Soy Protein (ISP) is not merely a high-protein ingredient; it is a complex biopolymer system engineered to stabilize multi-phase colloidal mixtures. In meat formulation, bakery systems, and vegetarian meat analogs, the stability of the food matrix relies entirely on the structural integrity of the protein matrix during processing.
When utilizing ISP for emulsion systems (often referred to as an "emulsion gel" with a ratio of 1:5:5 of Protein:Water:Oil), the polypeptide chains undergo dynamic changes. Under high-shear force chopping, the protein globule unfolds, exposing its hydrophobic amino acid residues to the fat phase, while the hydrophilic regions remain oriented toward the aqueous phase.
Our flagship emulsion types, including 9001BW and 9007B-C, are specifically designed to have a high surface activity, lowering the interfacial tension at the oil-water boundary and forming a robust visco-elastic film around oil droplets. This film resists thermal denaturation during cooking, retarding oil separation (syneresis) and maintaining the firm texture of processed meats.
| Property | Emulsion Type (9001BW/9007B-C) | Injection Type (9020/9026/9028) | Dispersion Type (9030/9032) |
|---|---|---|---|
| Protein Content (Dry Basis) | ≥ 90.0% | ≥ 90.0% | ≥ 90.0% |
| Moisture | ≤ 7.0% | ≤ 7.0% | ≤ 6.5% |
| Emulsification Ratio (P:W:O) | 1 : 5 : 5 (Min Stability Guarantee) | 1 : 4 : 4 (Optimized Viscosity) | N/A (Dispersion Focused) |
| Gel Strength (g/cm²) | 800 - 1200 | 200 - 400 | Low Gel / Pure Dispersion |
| NSI (Nitrogen Solubility Index) | 35% - 45% | 70% - 85% | > 90% |
Operating across a total area exceeding 1,000 mu, Xinrui Group has developed a deeply integrated circular economy. Founded in May 2003, our production network spans from raw agricultural bases to thermal power cogeneration plants and end-product processing systems.
Our soybean processing hub, Shandong Kawah Oils Co., Ltd. (established in 2014), handles 180,000 tons of domestic Non-GMO soybeans annually. Low-temperature meal is extracted and routed straight to our state-of-the-art protein isolation line. We utilize custom-engineered spray drying towers developed by DACHUANYUAN, which represent the largest single-line spray-drying systems in China.
On the wheat side, Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd) processes 500,000 tons of wheat flour annually. Our advanced tri-canter separation system ensures high-yield extraction of vital wheat gluten (VWG), starch A, and starch B. This industrial symbiosis yields unmatched thermal efficiency and guarantees a continuous raw material supply, shielding our global clients from supply chain disruptions.
By utilizing group-owned cogeneration plants (urban heating, gas, and electricity), Xinrui Group reduces carbon emissions per ton of soy protein by 22% compared to standard coal-reliant plants. This vertical power integration ensures that drying and concentration lines run uninterrupted, preventing protein degradation caused by sudden processing shutdowns.
Overcoming texture collapse, syneresis, and phase separation under extreme processing conditions
By adjusting the enzymatic hydrolysis of soy globulin, we tune the molecular weight of the peptides, targeting a specific HLB ratio optimized for meat fats and vegetable oils.
Our ISP forms stable gels at temperatures starting from 75°C to 80°C. Once gelled, the protein matrix becomes irreversible, locking in moisture and fats during sterilization.
All raw materials originate from strictly managed, geographical identity-preserved Non-GMO soybean cultivation zones in northeastern China.
Globally, the protein landscape is splitting into two clear pathways: cost-optimization of meat systems and structure-building in meat alternatives.
Underwritten by international standard audits and seamless factory-direct custom clearances
For multinational procurement leads, raw material compliance is paramount. Under the supervision of Guanxian Ruichang Trading Co., Ltd. (our group’s specialized trade integration vehicle established in 2011), over 70% of our production volume is shipped directly to customers in Europe, North America, Southeast Asia, and the Middle East.
