Guanxian Xinrui Industrial Co., Ltd. (formerly recognized as Guanxian Ruixiang Biotechnology Development Co., Ltd.) was established in 2007 with a registered capital of 100 million Yuan. Pioneering structural changes in agricultural deep processing, the company handles over 500,000 tons of wheat flour annually. Implementing advanced tri-canter separation technology, we extract high-grade wheat gluten and wheat starches (A and B grades) through an automated closed-loop system, mitigating environmental impact while driving industrial efficiency. The byproduct Starch B and pentosan are recycled directly into high-yield alcohol and animal feed production plants, representing a fully closed-loop circular economy.
Under our parent corporate umbrella, Shandong Kawah Oils Co., Ltd. was established in 2014 with 120 million Yuan in registered capital. It processes 180,000 tons of domestic Non-GMO soybeans annually, extracting high-purity soybean oil, low-temperature food-grade soybean meal, dietary fibers, and elite Isolated Soy Proteins (ISP). Backed by the state-of-the-art spray drying systems from DACHUANYUAN, our single-line capacity stands as a benchmark of scale and control within the domestic plant protein industry. Direct global distribution is managed by Guanxian Ruichang Trading Co., Ltd. (est. 2011), ensuring seamless end-to-end tracebility, regulatory clearance, and optimized logistics.
Isolated Soy Protein (ISP) intended for liquid dispersion requires deep alterations at the macromolecular level to avoid precipitation, sedimentation, and chalky mouthfeel. Beverage-grade ISP (specifically models like 9030 and 9032) undergoes physical-chemical modification to expose hidden hydrophilic groups along the protein chains. This decreases the steric hindrance of the polypeptide segments, improving hydration properties in aqueous solutions.
Technical Insight: By shifting the isoelectric point behavior during isolation and configuring optimal ionic-strength buffers, our beverage-grade ISP maintains high nitrogen solubility index (NSI > 90%) even after undergoing harsh high-temperature short-time (HTST) or ultra-high-temperature (UHT) thermal processing cycles.
In contrast to standard structural meat-grade proteins designed to gel and entrap water/fat under shear (such as 9007B-C or 9001BW), beverage-grade proteins focus on dispersion and stability. These proteins behave as natural amphiphilic surfactants, aligning at the oil-water interface to minimize interfacial tension. This prevents coalescence and phase separation in plant-based milks, RTD protein shakes, nutritional formulas, and acidic dairy alternatives.
Choosing the correct protein isolate requires matching the functional requirements of your application with the physical-chemical attributes of the specific grade. The table below outlines the core properties of our specialized ISP portfolio:
| Grade / Model Name | Primary Application Type | Solubility & Dispersion Index | Emulsification Power | Viscosity Profile (at 10% Sol.) |
|---|---|---|---|---|
| 9030 / 9032 | Beverage, Dairy, RTD Liquids | Excellent (NSI > 90%) | Moderate-Stable | Low (Fluid, Non-Gelling) |
| 9007B-C / 9007B-A | Meat & Emulsified Products | Moderate | High (Fat binding) | High (Forms rigid gel) |
| 9020 / 9026 / 9028 | Injection, Whole Muscle Meat | High | Moderate | Very Low (Cold dispersion) |
| 9003B / 9005B / 9003BA | Tofu, Vegetarian Analogues | Moderate-High | Moderate-High | Medium-High (Thermal gel) |
| 9500 Series | Premium Emulsified Franks & Hams | Moderate | Extraordinarily High | High Gel Strength |
Modern global beverage buyers face several critical formulation and supply chain challenges:
The global demand for high-protein functional beverages is rising. Integrating local production with international trade logistics allows Xinrui Group to cushion enterprise partners against price fluctuations. Our structural integration (owning energy cogeneration, gas supply, urban heating, wheat processing, and soybean crushing divisions) ensures stable utility overhead costs, shielding our production plants from macroeconomic price shocks.
Looking ahead, we are refining structural modification processes using enzymatic hydrolysis. This technique produces specific bio-active peptides with enhanced functionality. Furthermore, our dietary fibers and wheat starches (A and B grades) support the development of synergistic thickening and stabilization solutions. These products allow food manufacturers to source their entire texturizing and protein enrichment profiles from a single supplier.

Exporting over 60-70% of our production volume to competitive overseas markets, our products meet rigorous global regulatory, nutritional, and religious requirements. Our plants maintain high certification ratings from international third-party auditors:
Expert answers regarding functionality, logistics, and compliance
We are a vertically integrated group company named Xinrui Group that handles both manufacturing and export trading. The actual manufacturer of our isolated soy protein is Shandong Kawah Oils Co., Ltd (producing 50,000 tons of ISP annually). The vital wheat gluten is manufactured by Guanxian Xinrui Industrial Co., Ltd. (producing 30,000 tons annually). All international trade, invoicing, and logistics operations are managed by our export branch, Guanxian Ruichang Trading Co., Ltd.
Our operations are fully certified under HACCP, ISO9001, ISO22000, BRC, HALAL, KOSHER, and IP-NON GMO (audited by SGS). If your target country or formulation requires custom testing or additional health certificates, please request them through our sales engineers.
Our beverage-grade ISP (such as 9030) is modified to enhance thermal stability. It does not denature or cross-link easily during UHT cycles (e.g., 137°C for 4 seconds). This thermal resistance, combined with low viscosity, prevents sedimentation and minimizes fouling in pasteurizers and heat exchangers.
Our typical shelf-life is 12 to 18 months when stored in cool, dry conditions below 25°C. Packaging consists of multi-wall paper bags with food-grade polyethylene inner liners, available in 20kg or 25kg formats. We also provide large bulk bags for high-volume processors.
We utilize an Identity Preservation (IP) system that tracks soybeans from seed selection and local growing fields through harvest, storage, crushing, and final chemical extraction. Each batch undergoes PCR testing to confirm the absence of genetically modified DNA strands before shipping.
