Premium functional proteins engineered for meat binding, dispersion, gelation, and dairy alternatives.
Pioneering circular economy systems and high-throughput production capacities to serve international B2B buyers.
As global consumer preferences undergo a generational shift towards clean-label nutrition, sustainable plant-based proteins, and functional meat alternatives, modern B2B procurement demands high-purity ingredients that perform reliably under complex thermal and mechanical processing.
Isolated Soy Protein (ISP) Food Grade stands at the pinnacle of this functional ingredient spectrum. Boasting a minimum protein content of 90% (on a dry basis), our isolated soy proteins are derived exclusively from premium, Non-GMO soybeans grown in our dedicated agricultural bases. Through advanced low-temperature extraction technology and high-efficiency spray drying towers, we protect the native protein structures to deliver superior gelation, emulsification, water-binding, and solubility profiles.
By combining the agricultural and deep-processing infrastructure of Shandong Kawah Oils Co., Ltd. with the wheat protein and circular economy capabilities of Guanxian Xinrui Industrial Co., Ltd., the Xinrui Group delivers unmatched supply security, producing over 50,000 metric tons of isolated soy protein annually.
Targeted solutions for food scientists, production directors, and purchasing managers across multiple industrial categories.
Optimized for frankfurters, sausages, and patties. Promotes tight oil-water emulsion matrices, preventing fat separation during high-temperature cooking.
Tailored variants (9003B, 9005B) offering robust gelation properties to mimic the fibrous texture of muscle tissue in vegetarian meat analogs and traditional silken tofu.
Dispersion types (9030, 9032) exhibiting low viscosity at high concentrations. Essential for infant formulas, meal replacement shakes, and functional beverages.
Specifically processed (9020, 9026, 9028) for high solubility and low viscosity, enabling complete penetration into whole muscle meats without clogging injector needles.
To help procurement teams find the precise grade matching their manufacturing setup, we maintain strict control over our key functional parameters:
| Functional Grade Type | Key Models | Protein (Dry Basis) | Moisture | Primary Industrial Utility |
|---|---|---|---|---|
| Meat & Emulsion Type | 9007B-C, 9500, 9001BW | ≥ 90.0% | ≤ 7.0% | High gel strength, emulsification for meat sausages and canned goods. |
| Vegetarian & Tofu Type | 9003B, 9005B | ≥ 90.0% | ≤ 7.0% | Fibrillar structure builder, ideal for meat analogs & silken tofu. |
| Beverage & Dispersion Type | 9030, 9032 | ≥ 90.0% | ≤ 7.0% | Instant dispersibility, neutral taste, low viscosity profiles. |
| Injection Type | 9020, 9026, 9028 | ≥ 90.0% | ≤ 7.0% | Excellent solubility, zero needle blockage, high yield rentention. |
Integrating modern agriculture, advanced tri-canter separation, and ecological industrial chains.
At Xinrui Group, sustainability is not merely a compliance check—it is the foundation of our engineering architecture. Our industrial park processes 500,000 tons of wheat flour annually alongside 180,000 tons of domestic Non-GMO soybeans.
In our wheat processing line, we utilize imported tri-canter separation technology to divide wheat flour into vital wheat gluten, starch A, and starch B. Starch B and pentosan are dynamically routed to ethanol fermentation plants and animal feed production units. Similarly, the low-temperature meal from our soybean crushing facility forms the direct raw material feed for the isolated soy protein and soluble soy dietary fiber extraction lines. This symbiotic loop minimizes energy overhead, reduces carbon footprint, and maintains cost-leadership.
The critical step in determining the functional dispersion and powder consistency of food-grade isolated soy protein lies within the drying phase. Shandong Kawah Oils features the largest single spray drying tower lines in China, engineered by Dachuanyuan.
By controlling air inlet temperatures, droplet size distribution, and residence time within the tower chamber, we ensure our protein powders maintain high solubility index scores (NSI) and are virtually free from heat-denatured grittiness.
Our current R&D pipeline is focusing heavily on two technical frontiers:
Witness our automated manufacturing, quality control laboratories, and large-scale bulk warehousing.
Meeting strict international regulations to ensure streamlined customs clearance and formulation approval.
Operating in a global marketplace means adhering to diverse and demanding regulatory landscapes. Guanxian Ruichang Trading Co., Ltd. oversees direct factory-to-port logistics for over 70% of the group's total output, exporting to over 60 countries across the Americas, Europe, and Southeast Asia. We provide comprehensive documentation packages including Certificate of Analysis (CoA), Allergen declarations, Heavy Metal testing reports, and GMO testing traces.
