Direct from our state-of-the-art production facility, custom-engineered to meet global food manufacturer guidelines.
Founded in May 2003, XINRUI GROUP has built a diversified agricultural deep-processing industrial layout spanning more than 1,000 mu. Driven by integration, our operations encompass civil cogeneration, municipal heating, natural gas supply, and raw material processing capacities designed to maximize economic yield and resource recovery.
Within this ecosystem, GUANXIAN XINRUI INDUSTRIAL CO., LTD. (formerly known as GUANXIAN RUIXIANG BIOTECHNOLOGY DEVELOPMENT CO., LTD), established in 2007 with 100 million Yuan in registered capital, processes 500,000 tons of wheat flour annually. Our advanced tri-canter separation production line converts raw wheat into vital wheat gluten, wheat starch A, and wheat starch B. To close the industrial loop, Starch B and pentosans are directed into clean ethanol and high-nutrient animal feed production, establishing a sustainable, closed-loop circular economy.
Export activities are managed by GUANXIAN RUICHANG TRADING CO., LTD., founded in 2011 with 6 million Yuan in registered capital. Direct export channels transfer isolated soy protein, wheat gluten, soluble dietary fiber, vermicelli, and ethanol to global customers, accounting for over 70% of the group's capacity and ensuring highly integrated manufacturer-to-buyer transactions.
Our dedicated soy extraction subsidiary, SHANDONG KAWAH OILS CO., LTD., established in 2014 with a registered capital of 120 million Yuan, is a key agricultural industrialization leader. The facility processes 180,000 tons of locally sourced, strictly NON-GMO soybeans annually. Through modern extraction and fractionation protocols, raw beans are separated into premium food-grade soybean oil, low-temperature meal, isolated soy protein (ISP), and dietary fiber.
At the center of our engineering setup is the advanced spray drying installation designed by DACHUANYUAN. This system features one of the largest single-line spray drying capacities in China. The processing line operates under highly clean, automated controls that prevent contamination while ensuring consistent powder particle distribution, hydration rates, and protein functional retention.
By monitoring the extraction pH, precipitation isoelectric points, and flash thermal conditions, we produce isolated soy protein with optimal molecular structures. This allows us to supply functional proteins tailored for emulsification, gelation, and dispersion in food systems worldwide.
How we design isolated protein matrices to solve structural challenges in meat, beverage, and plant-based formulations.
Our meat and emulsion-type proteins (such as the 9007B and 9001BW series) utilize controlled shear alignment. They create tough thermal-reversible gel matrices that lock in fat and moisture during high-shear meat chopping and cooking processes.
For RTD beverages, dairy alternatives, and powder mixes, our dispersion types (like the 9030 and 9032 series) are engineered for low viscosity under high concentration. This guarantees fast wetting, zero graininess, and stable suspension profiles.
From seed selection at our dedicated agricultural bases through extraction and shipping, our Identity Preserved (IP) systems prevent GMO contamination. Every shipment is fully traceable back to its origin farm.
Reducing unit energy costs and logistics delays through strategic plant design and utility integration.
Xinrui Group operates its own civil cogeneration plant, municipal heating network, and local gas supply systems. By generating steam and power on-site, Kawah Oils and Guanxian Xinrui Industrial significantly reduce production costs compared to facilities reliant on public energy grids.
This thermal integration ensures that energy-heavy spray drying processes remain cost-effective and immune to standard power grid fluctuations. Additionally, byproduct utilization pathways (such as using wheat starch B for industrial ethanol) allow us to operate with minimal raw materials waste and solid environmental compliance.
Operating a dedicated trading arm (Guanxian Ruichang Trading) right next to our production site enables rapid customs clearance, container consolidation, and direct-to-port logistics. This close proximity helps reduce transit times and keeps shipping lanes running smoothly.
Selecting the right protein characteristics for your specific food manufacturing application.
Our main ISP product range features high protein content (≥90% dry basis) designed for meat injection, emulsion systems, fresh tofu production, and instant nutritional drinks.
Extracted from high-quality soy hulls, our fiber offers excellent water-binding capacity and dietary enrichment for bakery products, health foods, and low-calorie diets.
Our wheat gluten features natural viscoelastic properties that help improve dough strength, enhance gas retention, and optimize texture in artisanal baking and noodle production.
Processed through our clean tri-canter separation lines, this starch serves as an excellent thickening agent, binder, and texturizer in food manufacturing.
Explore our deep-processed products, developed and verified to comply with strict international regulatory standards.
Our processing lines undergo regular third-party audits to comply with food safety regulations in Europe, North America, and the APAC region.
