Engineered high-functional proteins tailored to diverse global applications, directly exported from our integrated Chinese manufacturing facilities.
In the rapidly evolving global food science sector, the demand for stable, high-functional plant macromolecules has reached unprecedented levels. As a leading manufacturer and exporter of Non-GMO plant proteins, Xinrui Group—incorporating the production powerhouses of Shandong Kawah Oils Co., Ltd. and Guanxian Xinrui Industrial Co., Ltd.—engineered state-of-the-art agricultural deep processing ecosystems.
Our vertically integrated processing methodologies guarantee that every metric ton of Isolated Soy Protein (SPI) preserves its vital functional traits: high gelling, superior emulsification, controlled dispersion, and high water-binding capacity. We operate from the heart of China's prime soybean processing region, utilizing regional Non-GMO crops to produce high-purity protein fractions that satisfy international food production, pharmaceutical, and nutritional frameworks.
With a massive combined milling and extraction scale—milling 500,000 tons of wheat and processing 180,000 tons of Non-GMO soybean seeds annually—we achieve unmatched consistency and security of supply. Through our dedicated export branch, Guanxian Ruichang Trading Co., Ltd., we deliver more than 60-70% of our production volume directly to over 50 countries, facilitating seamless global trade integrations.
Uncompromising quality backed by monumental industrial capacity and advanced extraction technologies.
The technological core of our soybean protein isolation is housed at Shandong Kawah Oils Co., Ltd. (established in 2014, registered capital of 120 million Yuan). As a provincial-level leading agricultural industrialization enterprise, Kawah Oils integrates raw crop cultivation, advanced biochemistry research, deep extraction, and global trade operations.
Our primary manufacturing advantage lies in our state-of-the-art processing facility featuring the highly advanced spray drying tower from DACHUANYUAN. Boasting the largest single production line capacity in China, this drying system manages protein particle distribution with extreme precision, avoiding heat-induced denaturation and preserving the primary functional groups of the proteins.
Parallel to this, our sister operation, Guanxian Xinrui Industrial Co., Ltd. (established in 2007, registered capital of 100 million Yuan), processes 500,000 tons of wheat flour annually. Implementing the cutting-edge tri-canter separation system imported from Europe, the entire manufacturing chain remains completely clean, closed, and sanitary, setting the benchmark for the domestic plant macromolecule industry.
Aligning physical chemistry attributes of proteins with practical food manufacturing workflows.
For sausages, hams, burgers, and cold cuts, protein gelling determines bite, sliceability, and moisture retention during cooking.
Liquid formulations require proteins to remain suspended without settling or introducing chalky textures.
Vegetarian analogs depend on fibrous textures, stretch, and chewiness to replicate the sensory qualities of meat.
Enhancing nutritional values while maintaining dough rheology and structure during baking.
Xinrui Group was established in May 2003, covering a total area of more than 1,000 mu. After years of rapid expansion, we successfully engineered a diversified, self-sustaining circular economy. Our operations integrate urban heating, co-generation systems, and clean gas supply alongside our deep agricultural processing structures.
By utilizing our own municipal co-generation facilities, we guarantee stable, uninterrupted energy supply to our extraction lines. This integration lowers energy overheads and ensures stable manufacturing costs regardless of external energy fluctuations.
Furthermore, the wheat process circular chain utilizes Starch B and pentosan for eco-friendly animal feed and alcohol production. By ensuring that every fraction of our input raw materials is utilized, we achieve high process yields and minimize our ecological footprint.
This complete closed-loop model extends down to our Wheat and Non-GMO Soybean Planting Bases. Operating with localized control over the planting seed selections and cultivation parameters, we guarantee pure genetic integrity of the raw grains before they enter our production lines.

Evaluating the future trajectory of global plant protein sourcing and processing technology.
Consumers and regulators worldwide are shifting away from genetically modified crops. Maintaining a strictly documented Identity Preserved (IP) system from seed selection to final powder packaging is now a baseline requirement for high-end European and North American markets.
Formulators no longer accept one-size-fits-all soy protein isolates. The market expects application-specific molecular weights, controlled gel strengths, and targeted viscosity curves to optimize specific meat or beverage production lines.
ESG compliance is becoming a critical sourcing filter. Modern factories must utilize co-generation networks, minimize water waste, and optimize thermal efficiencies through vertical integration, similar to the industrial circular ecosystem run by Xinrui Group.
Fully verified, certified, and compliant processing ensuring seamless international customs entry.
At Shandong Kawah Oils and Guanxian Xinrui Industrial, the safety of plant protein molecules is our absolute operational priority. We utilize strict chemical analysis and in-line infrared spectroscopy to analyze moisture, protein density, fat concentration, ash limits, and microbiological counts on every production run.
By integrating advanced wet extraction technology and the DACHUANYUAN spray drying system, we achieve stable physical profiles: free-flowing powders, consistent color values, and excellent hydration dynamics.
To support international imports, our export division, Guanxian Ruichang Trading Co., Ltd., coordinates all necessary documentation, including IP-Non-GMO declarations, phytosanitary certifications, heavy metal testing, and allergen protocols.
