Advanced structural isolates designed for superior emulsification, water-binding capacity, and gel formulation
In the contemporary global food manufacturing and chemical synthesis sectors, plant-derived proteins have evolved from simple dietary substitutes into essential functional components. The modern industry relies heavily on soy protein extract (including isolated soy proteins, concentrated proteins, and dietary fibers) to solve structural, emulsion-stability, and nutritional challenges in large-scale formulations. Driven by global clean-label policies, plant-based nutrition demands, and economic cost-efficiency targets, food conglomerates are restructuring their supply chains around vertically integrated manufacturers.
Soy protein extracts represent a multi-billion-dollar global commodity. Historically dominated by commodity-grade crushers, the industry has undergone a technological pivot. Today's commercial applications demand precise physical-chemical characteristics: controlled gel strength, custom viscosity profiles, and clean sensory properties. Regional demands vary greatly; North American and European markets require high-purity isolates with specific dispersion ratings for alternative dairy products and performance beverages. Simultaneously, major food processors in Latin America, Eastern Europe, and Southeast Asia look for reliable functional proteins that offer superior fat and water binding properties to optimize processed meat systems.
Our operational platform is anchored by Xinrui Group (established in May 2003, spanning over 1,000 mu, generating an annual output of 2.8 billion Yuan). Through its specialized subsidiaries, the group operates a highly efficient circular economy industrial chain. Under this structure, Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd.) processes 500,000 tons of wheat flour annually, producing vital wheat gluten, wheat starch A, and wheat starch B. To maximize resource recovery, starch B and pentosan are recycled for alcohol and animal feed production, utilizing advanced tri-canter separation technology.
Our soy protein extraction operations are managed by Shandong Kawah Oils Co., Ltd. (established in 2014, with a registered capital of 120 million Yuan). Shandong Kawah Oils is a provincial-level agricultural industrialization enterprise that integrates cultivation, research, deep-processing, and import/export operations. Processing 180,000 tons of domestic Non-GMO soybeans annually, Kawah Oils produces premium food-grade low-temperature soybean meal, isolated soy proteins, and dietary fibers.
A major asset of our soy protein production line is the specialized spray drying tower engineered by DACHUANYUAN. As one of China's largest single-line spray drying towers, it ensures uniform particle size distributions, consistent moisture levels, and stable dispersion characteristics in our final products. This high-capacity system minimizes thermal damage to the protein structures, maintaining the high emulsification and gelling indexes required by major food manufacturers.
All international logistics and trade are managed directly by Guanxian Ruichang Trading Co., Ltd. (founded in 2011 with a registered capital of 6 million Yuan). By directing more than 60-70% of our production volume to overseas markets, Ruichang Trading bridges our raw production capability with complex global trade frameworks, offering direct factory exports to our global partners.
The manufacturing model of Shandong Kawah Oils highlights why Chinese production leads the global plant protein market. Our competitive advantage relies on three pillars: scale integration, local raw material control, and energy self-reliance.
By integrating municipal heating, cogeneration plants, and gas supply systems within the Xinrui Group, our manufacturing facilities operate with highly optimized steam and electrical energy profiles, insulating production from energy cost spikes.
We source raw materials from our dedicated domestic wheat and Non-GMO soybean planting bases. This ensures strict identity preservation (IP) from cultivation to final processing, fulfilling strict European and North American non-GMO standards.
Operating one of the largest single spray-drying lines in China allows us to produce high volumes with excellent batch-to-batch consistency. Our large-scale operations ensure stable supply and pricing even during global market shifts.
In addition, our location in Shandong's agricultural corridor grants us access to direct highway networks and key deep-water ports (such as Qingdao Port). This enables swift delivery and secure logistics across North America, Europe, the Middle East, and Southeast Asia.
Soy protein extracts are highly complex, versatile macromolecules. Our specific product lines are optimized for distinct food processing and industrial matrices:
In hot dogs, sausages, and luncheon meats, water and fat binding are critical for quality and yield. Our Meat & Emulsion type isolates (such as 9007B-C, 9007B-A, and 9001BW) are engineered to establish high-viscosity emulsions that remain stable under thermal processing. These proteins form structured gels that bind free water and encapsulate fat droplets, improving product texture and reducing purge loss during shelf storage.
For whole muscle meats, hams, and poultry cuts, protein isolates must dissolve quickly without clogging injection needles. Our Injection-type isolates (9020, 9026, 9028) feature low viscosity under high shear, clean dispersion, and low dust levels. They penetrate deep into muscle tissues, binding water during curing and cooking to enhance juiciness and sliceability.
The formulation of meat alternatives requires proteins that can texturize and form chewable fibrils. Our Vegetarian-type isolates (9003B, 9005B) are tailored for high water absorption and thermo-irreversible gelation. They work well in both high-moisture extrusion (HME) and low-moisture extrusion processes, creating textures that closely mimic animal muscle tissue.
Liquid systems demand protein stability across different temperatures and pH levels. Our Dispersion-type isolated soy protein 9030 is modified to dissolve quickly in water, providing a smooth mouthfeel and preventing sedimentation in protein powders, meal replacements, and plant-based milk formulations.
In international B2B food ingredient procurement, product safety and certification compliance are non-negotiable. Shandong Kawah Oils and Guanxian Xinrui Industrial run under strict quality management systems verified by leading global bodies.
We maintain clean-label trace programs and carry certifications including IP-NON GMO, BRC (British Retail Consortium), HACCP, ISO9001, ISO22000, HALAL, and KOSHER. For buyers in Europe and the Americas, our IP Non-GMO certification guarantees that our soybeans are isolated from GMO varieties throughout the planting, harvesting, transportation, crushing, and extraction stages.
Our logistical teams manage shipping container space, moisture-controlled ocean freight packaging, and custom bulk bag systems (typically 20kg, 25kg, or customized super-sacks). This level of care ensures that our high-purity protein powders arrive free from contamination, clumping, or moisture damage.

We are a fully integrated group company named Xinrui Group. Our soy protein isolate is manufactured directly by Shandong Kawah Oils Co., Ltd, which produces 50,000 tons of isolated soy protein annually. Our vital wheat gluten and starch are manufactured by Guanxian Xinrui Industrial Co., Ltd., which processes 500,000 tons of wheat flour per year. Export operations are managed by our trading subsidiary, Guanxian Ruichang Trading Co., Ltd.
We hold HACCP, ISO9001, ISO22000, BRC, HALAL, KOSHER, and IP-NON GMO certifications. We also work with independent testing bodies like SGS to meet specific destination import standards.
Our Emulsion-type proteins (e.g., 9007B-C) form a strong, elastic, and thermo-irreversible gel that binds fat and water in finely chopped meat systems. In contrast, our Injection-type proteins (9020) are designed with a lower viscosity profile. They disperse easily without clogging needles and bind water within the muscle structure of whole cuts without creating tough surface layers.
We source soybeans exclusively from our verified Non-GMO planting bases in China. Our Identity Preservation (IP) program monitors the crop from seed distribution to farming, transportation, crushing, and final protein extraction, preventing cross-contamination with genetically modified grains.
Our standard Minimum Order Quantity (MOQ) is 1 FCL (Full Container Load). Lead times vary between 15 and 30 days depending on the destination port and packaging specifications. We offer customized packaging options including 20kg, 25kg, and super-sacks.
