Premium range of functional proteins engineered for meat binding, gelling strength, and rapid dispersion.
In high-yield food processing, the thermodynamic gelation capacity of Soy Protein Isolate (SPI) is a core determinant of final product quality. Gelling is not merely a swelling phase; it is an ordered molecular restructuring process. Under structured heat treatments, the globular fractions of soy protein—predominantly glycinin (11S) and beta-conglycinin (7S)—undergo structural denaturation. This chemical shift exposes hydrophobic regions that were previously folded inside the native protein molecules.
When temperatures exceed the denaturation point (typically above 70°C for 7S and 90°C for 11S), the unfolded polypeptide chains align, allowing hydrophobic interactions, hydrogen bonding, and disulfide exchange reactions to establish a robust, cohesive three-dimensional network. This cross-linked matrix effectively traps water molecules and fat globules, forming a strong, viscoelastic gel. Achieving a precise balance between water absorption, oil retention, and thermal stability requires meticulous extraction processes, uniform spray-drying conditions, and high-performance refining systems.
As a leading global soy protein isolate gel manufacturer, we optimize the extraction and purification processes to preserve these structural protein profiles. This ensures that food producers can achieve stable gelation matrices under high-shear industrial chopping, injection, and thermal processing environments.
The global demand for high-gelling isolated soy protein is driven by two main sectors: the traditional emulsified meat industry and the rapidly expanding plant-based analog sector. As commercial processing scales up, buyers look for proteins that solve critical production challenges:
Our production facilities represent the cutting edge of modern Chinese bioprocessing. Shandong Kawah Oils Co., Ltd. (a subsidiary of the Xinrui Group) processes 180,000 tons of domestic non-GMO soybeans annually. We use a step-by-step extraction process to yield cold-pressed non-GMO soybean oil, low-temperature food-grade soybean meal, high-gel isolated soy protein, and soluble soy dietary fiber.
Our factory features China's largest single-line spray drying system from DACHUANYUAN. This advanced drying tower ensures consistent particle size, uniform dispersibility, and gentle thermal drying. By minimizing heat damage during drying, we preserve the protein’s functional gelling properties.
The Xinrui Group's circular industrial model connects raw material sourcing with complete processing. Our wheat processing facility, Guanxian Xinrui Industrial Co., Ltd., processes 500,000 tons of wheat flour annually, using advanced tri-canter separation technology to extract vital wheat gluten and wheat starch.
This circular loop uses processing by-products to manufacture alcohol and animal feed, minimizing waste. Integrating raw material cultivation, advanced refining, and direct global export under one group guarantees supply chain stability and high cost-efficiency.
Functional proteins must meet the specific processing demands of different applications. Our isolated soy protein series is designed for targeted performance across key food sectors:
Types: 9001BW / 9007B-C. Designed for high-speed chopping lines. It builds a strong protein-water-oil emulsion that prevents shrinkage and juice loss during boiling, canning, or baking.
Types: 9003B / 9005B. Developed for meat-free products, tofu, and plant-based burgers. It provides the firm, elastic texture required to mimic natural meat fibers.
Types: 9020 / 9026 / 9028. Features low viscosity and high solubility. Extracted to flow smoothly through fine injector needles without clogging, binding inside whole muscles to improve sliceability.
Types: 9030 / 9032. Engineered for rapid dispersion and low viscosity. Ideal for dairy alternatives, powdered nutrition blends, and acidic beverages where solubility is key.
Established in May 2003, Xinrui Group spans over 1,000 mu. The group operates across cogenerated power supply, municipal heating, natural gas distribution, wheat deep processing, non-GMO soybean processing, and raw agricultural base management, generating an annual output value of 2.8 billion Yuan.
Under our integrated structure:
To support global exports, we maintain strict quality control standards throughout our processing cycle. Each batch of isolated soy protein is fully traceable back to its planting source, verifying its non-GMO identity. Our factories are certified by leading international food safety and product standard organizations:
