As a global circular economy leader, we supply high-purity protein fractions, modified starches, and functional binders to international buyers. Explore our key wheat and soy segments.
The plant-based food ingredients paradigm is undergoing a massive evolutionary shift. Traditionally dominated by soy isolates and vital wheat gluten, industrial food developers are rapidly diversifying formulation matrixes to meet intense consumer demand for hypoallergenic labels and non-GMO claims. This is where Brown Rice Protein emerges as a frontrunner. Extracted from the high-protein brown rice (Oryza sativa) grain endosperm through complex structural enzymes, it delivers a highly bioavailable nutritional footprint free from the top eight global food allergens.
At Xinrui Group, we recognize that raw material supply chain vulnerability has challenged global brands. By bridging our deep grain refining capabilities—from processing 500,000 tons of wheat flour annually at Guanxian Xinrui Industrial to crushing 180,000 tons of soybean annually at Shandong Kawah Oils—we are scaling clean enzymatic extraction lines to serve as a reliable, direct manufacturer and exporter of brown rice protein solutions. Our focus remains on high digestibility, optimal dispersion index, and low heavy metal profiles, guaranteeing food safety benchmarks that align with NOP USDA Organic and European standards.
Achieving a neutral sensory profile, high solubility, and minimum 80% to 90% dry-basis protein content from brown rice requires strict process parameters. Traditional solvent extraction is obsolete; our green wet-milling technology uses a low-temperature biochemical process.
High-grade brown rice grains are wet-milled into a fine particle slurry to expose the protein-starch matrix.
Food-grade alpha-amylases break down starch polymers into soluble sugars, leaving structural proteins intact.
Centrifugal tri-canter systems separate insoluble fiber fractions from the protein-rich concentrate.
Ultrafiltration removes mineral impurities and controls heavy metal concentrations to ensure strict safety limits.
Low-temperature spray towers yield fine, consistent, dispersible powders with optimal solubility.
Xinrui Group operates a modern plant-based refining infrastructure. From grain sourcing to deep extraction, we maintain full control over quality and output.
Brown rice protein concentrates offer a complete amino acid profile rich in leucine and BCAAs, similar to whey. They provide a safe alternative for athletes with dairy, lactose, or soy allergies.
Because it is gentle on digestion and has very low allergenicity, our purified isolate is widely used in baby food formulas and enteral medical nutrition products.
When blended with Vital Wheat Gluten and Soy Protein Isolate, it yields high-strength texturized meat alternatives with improved fiber structure, water retention, and mouthfeel.
GUANXIAN XINRUI INDUSTRIAL CO., LTD. (formerly known as GUANXIAN RUIXIANG BIOTECHNOLOGY DEVELOPMENT CO., LTD) was established in 2007 with a registered capital of 100 million Yuan. The company processes 500,000 tons of wheat flour annually. Using this raw material, we produce wheat gluten, wheat starch A, and wheat starch B.
Starch B and pentosan are recycled for alcohol and animal feed production, forming a zero-waste industrial circular economy. Our facility utilizes advanced tri-canter separation technology for wheat gluten production, operating in a clean, closed, and fully automated environment. Our output, equipment, technology, and quality standards lead the domestic industry.
Established in 2014 with a registered capital of 120 million Yuan, SHANDONG KAWAH OILS CO., LTD. is a leading provincial enterprise in agricultural industrialization. We integrate seed selection, scientific R&D, deep processing, and export operations, processing 180,000 tons of NON-GMO soybeans annually.
We refine domestic NON-GMO soybeans into soybean oil, low-temperature food-grade meal, isolated soy protein, and dietary fiber. Utilizing high-efficiency spray drying towers from DACHUANYUAN, our facility houses one of the largest single-line soy protein isolate production systems in China.
Export operations are managed by GUANXIAN RUICHANG TRADING CO., LTD. (founded in 2011, 6 million Yuan registered capital). We export our isolated soy protein, wheat gluten, dietary fiber, starch, and ethanol directly to overseas buyers, representing over 70% of our group's capacity.
Established in May 2003, XINRUI GROUP covers an industrial footprint of over 1,000 mu. The group operates municipal cogeneration, urban heating, industrial gas supply, and raw agricultural processing networks.
By integrating municipal power generation with our wheat and soybean processing lines, we optimize energy usage, reduce carbon emissions, and lower production costs. This vertical integration ensures competitive pricing and reliable supply for our international buyers.
