Explore our flagship commercial-grade Soy Protein Isolates, Soy Fibers, and Wheat Gluten products engineered for high functional efficacy.
A globally integrated plant protein manufacturing powerhouse utilizing sustainable agricultural systems and leading bioseparation technologies.
Established in May 2003, Xinrui Group represents a highly integrated modern agricultural conglomerate covering a total area of more than 1,000 mu. Under our diversified business model, we manage a deep circular economy loop comprising sustainable power generation, municipal steam heating systems, urban natural gas utility support, and large-scale agricultural deep-processing operations. Generating an annual output value of 2.8 Billion Yuan, our operations span multi-stage facilities optimized to yield peak productivity and industrial reliability.
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. Processing 500,000 tons of high-grade wheat flour annually, the facility utilizes raw wheat feedstock to manufacture Vital Wheat Gluten, Wheat Starch A, and Wheat Starch B. Driven by sustainable development, our Wheat Starch B and pentosan co-products are directly routed to upstream bio-alcohol (ethanol) manufacturing units and eco-friendly animal feed formulations, creating a closed-loop zero-waste processing matrix.
Established in 2014 with a registered capital of 120 million Yuan, Shandong Kawah Oils Co., Ltd. stands as a key provincial leading agricultural industrialization enterprise. Operating custom-built industrial infrastructure, Kawah Oils processes 180,000 tons of Identity-Preserved (IP) Non-GMO soybeans annually. We execute continuous step-by-step extraction starting with food-grade Non-GMO low-temperature desolventized soybean meal, leading to high-performance Isolated Soy Proteins, functional dietary fibers, and organic oils.
Our facility houses the advanced spray drying tower technology from DACHUANYUAN. Sporting a massive single-line manufacturing volume, it represents one of the largest single isolated soy protein production lines operational in China, ensuring structural consistency, dry flowability, and clean microbiology for global markets.
To serve international customers with speed and efficiency, Guanxian Ruichang Trading Co., Ltd. was founded in 2011 with a registered capital of 6 million Yuan. Functioning as the dedicated international trading and logistics arm of Xinrui Group, Ruichang handles the direct export of low-temperature Isolated Soy Protein, Vital Wheat Gluten, Soluble Dietary Fiber, vermicelli, and superior-grade bio-ethanol. By exporting over 70% of the Group's production volume, Ruichang offers direct factory prices, optimized logistics, and end-to-end quality assurance.
Deep molecular insights into enzymatic bioconversion, structural functionalization, and high-purity protein refining processes.
Unlike harsh traditional hydrochloric acid (HCl) extraction methods that risk generating harmful 3-MCPD (3-monochloropropane-1,2-diol) residues, Kawah Oils and Xinrui Group emphasize advanced enzyme-driven multi-protease biocatalysis. We use precision endopeptidases and exopeptidases to selectively sever peptide bonds in our organic vegetable proteins, resulting in a controlled Degree of Hydrolysis (DH) that preserves beneficial nutrition and enhances flavor delivery.
To achieve exceptional purity in our Vital Wheat Gluten, we run imported high-capacity tri-canter separation lines. Operating under clean, closed, and fully automated conditions, this three-phase separation process isolates pure gluten, dense Wheat Starch A, and lighter Starch B. The process minimizes thermal stress on the protein molecules, leaving their natural visco-elasticity, water absorption, and structure intact.
To process raw liquid protein isolate into a stable, highly dispersible food powder, we utilize a large-capacity DACHUANYUAN spray drying tower. Operating at custom inlet temperatures and utilizing high-velocity atomization nozzles, the tower flashes off moisture without scorching the product. This protects structural properties like emulsification strength, gelling ability, and nitrogen solubility.
How our organic hydrolyzed and isolated proteins solve challenging functional problems in commercial food processing.
For emulsion type sausages, meat analogs, and canned meat products, our meat-type isolated soy proteins (9006B, 9001BW, 9007B-C) build strong heat-induced gel structures. They bind water and oil phase particles, preventing fat release during thermal processing. Our Vital Wheat Gluten creates fibrous structures that mimic animal muscle tissues, improving chewiness and bite.
Our beverage-grade dispersion types (9030, 9032) offer good stability in acidic and neutral liquid formulations. Low molecular weight organic hydrolyzed proteins exhibit high solubility, clarity, and stability in dynamic pH environments. This makes them ideal for infant formulas, sports protein drinks, clinical nutrition, and plant-based milk products.
Organic Hydrolyzed Vegetable Protein (HVP) acts as a clean-label ingredient rich in glutamic acid and other sensory-active peptides. It intensifies flavor profiles in soups, snacks, and vegetarian dishes, eliminating the need for synthetic flavor additives and monosodium glutamate (MSG).
Combining localized raw material sourcing, automated processing, and integrated energy systems for stable industrial production.
Global food manufacturing requires high supply chain reliability. Located in Guanxian, Shandong, China, Xinrui Group utilizes a localized industrial integration model to buffer against resource market volatility. By sourcing raw inputs directly from our dedicated wheat and Non-GMO soybean planting bases, we maintain raw material traceability while optimizing raw costs.
Additionally, we run a cogeneration plant that supplies clean energy directly to our extraction and spray drying units. This vertical energy integration protects our manufacturing operations from regional power interruptions and reduces manufacturing emissions, keeping production costs stable through high-volume production cycles.
This closed-loop system is managed by ERP logistics control, linking raw crop entry to physical container delivery at Qingdao port, assuring buyers of uninterrupted product supply.
