Premium grade isolated soy proteins and plant-derived functional ingredients sourced from our fully integrated manufacturing complexes.
Founded in 2007, Guanxian Xinrui Industrial Co., Ltd. (formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd) launched with a vision to redefine the efficiency of plant protein extraction. Backed by registered funds of 100 million Yuan, the company processes 500,000 tons of wheat flour annually. Our closed-loop system utilizes wheat raw materials to yield premium wheat gluten alongside wheat starch A and wheat starch B. To ensure zero waste, secondary streams like starch B and pentosan are recycled for ethanol and high-nutritional-value animal feed.
This deep-processing circular economy represents our core ethos. By importing the industry's leading tri-canter separation technology for wheat gluten production, our lines operate within sterile, fully closed configurations. Today, our technological footprint, total output, and rigorous quality standards stand at the absolute forefront of the global ingredient industry.
To further establish leadership in the plant-based protein sector, Shandong Kawah Oils Co., Ltd. was established in 2014 with a registered capital of 120 million Yuan. Serving as a leading agricultural industrialization enterprise, Kawah Oils integrates raw agriculture, R&D, deep processing, and import/export capabilities, handling 180,000 tons of domestic Non-GMO soybeans per year.
The facility processes Non-GMO soybeans to extract edible oils, low-temperature meal, isolated soy proteins, and dietary fiber. Central to this extraction process is our state-of-the-art spray drying technology, utilizing the world-renowned Dachuanyuan spray drying tower system. With a single-line capacity that exceeds traditional industry benchmarks, it represents one of the largest single spray-drying lines in China, ensuring structural consistency, superior dispersion, and optimal particle-size distribution across all protein isolates.
Our wheat processing utilizes high-shear, multi-phase separation techniques to isolate gluten from wheat starches with zero thermal degradation, preserving molecular protein elasticity.
Ultra-large scale atomization ensures that every particle of soy protein isolate achieves consistent hydration, bulk density, and instant dispersion profiles required for beverage lines.
From seed selection to finished bag packing, our entire process is physically segregated and audited to guarantee zero cross-contamination with genetically modified varieties.
In standard isolated soy protein (ISP) manufacturing, the soy whey stream—comprising the soluble proteins, oligosaccharides, and minerals that remain after acid precipitation—has historically been viewed as a high-BOD (Biochemical Oxygen Demand) waste stream. Today, under the Xinrui Group's circular bio-refinery model, we are mapping a technology transformation that turns soy whey into a high-value protein resource.
The extraction of Soy Whey Protein relies on a multi-stage membrane separation system. First, ultrafiltration (UF) loops isolate soluble soy whey proteins (such as soybean basic globulin and 2S albumins) directly from the raw whey liquid. This is followed by nanofiltration (NF) and reverse osmosis (RO) to concentrate the permeate, reclaiming process water and purifying bioactive soy oligosaccharides (sucrose, raffinose, and stachyose) for prebiotic applications. This system reduces waste treatment overhead while capturing functional proteins with excellent foaming and gelling properties.
"By integrating multi-stage membrane recovery, our plants capture the valuable 2S albumin fraction from soy whey, providing B2B buyers with an ingredient that features an exceptional essential amino acid profile and high digestibility."
Industrial food processors face diverse functional requirements. Our research and development center bridges this gap with targeted formulations:
Operating out of Guanxian, Shandong, our production facilities represent a hub of Chinese industrial modernization. The integration of Guanxian Xinrui Industrial and Shandong Kawah Oils under the Xinrui Group yields unmatched supply chain resilience. By operating our own cogeneration power plant, urban heating networks, and local gas supply lines, our production facilities are shielded from municipal energy fluctuations. This ensures continuous operations and stable pricing even during global supply chain volatility.
Our raw material supply is secured through localized Non-GMO soybean planting bases. Because we control the agricultural inputs and manage logistics via our dedicated trading entity, Guanxian Ruichang Trading Co., Ltd., we maintain full chain-of-custody tracking. This integration offers global procurement managers reliable volume commitments, consistent batch quality, and transparent trace-back capability.
With exports accounting for over 60-70% of our total production capacity, our teams are deeply familiar with the regulatory, chemical, and physical parameters required by international buyers. Whether managing the viscosity curve of plant-based dairy, testing heavy metal limits for EU customs clearance, or managing strict microbial thresholds for infant nutrition, our integrated export team provides the documentation, certifications, and technical support required for seamless onboarding.
Explore our core plant-based protein fractions, dietary fibers, and functional wheat derivatives engineered for global distribution.
Export operations are managed through Guanxian Ruichang Trading Co., Ltd., founded in 2011 with 6 million Yuan in registered capital. Operating as the group's dedicated export window, Ruichang Trading ships isolated soy protein, wheat gluten, and soluble dietary fiber directly from our processing facilities to overseas ports. This direct-from-factory structure ensures clear chain of custody, reduces intermediate handling, and optimizes transit times.
By handling logistics internally, we offer comprehensive container monitoring, temperature-controlled transit options, and direct coordination with major shipping lines. This level of oversight ensures that our products reach your facility in peak condition, with complete traceability documentation.
