Engineered for food processing efficiency, high functional yield, and clean-label parameters.
Enabling modern mass production, high-yield margins, and structural integrity in animal proteins.
In the highly competitive global food processing market, meat processors face the dual challenge of maximizing product yield while preserving natural meat texture, juiciness, and sliceability. Injection-grade Isolated Soy Protein (ISP) is specifically engineered to address these challenges. Unlike standard chopping or emulsifying soy proteins, injection-type proteins require exceptionally low viscosity, instant solubility, and highly stable dispersion properties under low temperatures and saline conditions.
When injected using multi-needle machines into whole muscle meats (such as hams, bacon, chicken breasts, and turkey cuts), these proteins migrate deeply into the muscle fibers. Upon thermal processing, they form a cohesive cold-set gel matrix that binds free water, seals in natural fats, and dramatically reduces cook shrink, leading to higher industrial yield margins.
Engineered at the molecular level for rapid dispersion and zero needle clogging.
The performance of Isolated Soy Protein (ISP) 9020/9026/9028 relies on advanced extraction processes that optimize the balance of 7S and 11S globulins. This precise molecular control gives our injection-type soy proteins unique industrial advantages:
Under dynamic cold temperatures, the protein particles remain completely dispersed without swelling prematurely. This guarantees seamless flow through needle nozzles as small as 1.5mm, eliminating machine downtime caused by clogging.
Industrial brines are packed with high concentrations of sodium chloride, sodium tripolyphosphate (STPP), and other additives. Our injection series is specially modified to resist salting-out effects, maintaining solubility even in saturated saline solutions.
Once injected and subjected to cook cycles (65°C - 80°C), the protein proteins undergo irreversible thermal gelation. This traps moisture inside the meat myofibrils, preventing water loss during vacuum packaging and storage.
Processing 180,000 tons of Non-GMO soybeans and 500,000 tons of wheat flour annually.
Established in May 2003, Xinrui Group spans over 1,000 mu and has developed into a fully diversified agricultural industrialization giant with an annual output value of 2.8 billion Yuan. Our vertical integration strategy begins at our dedicated Wheat & Non-GMO Soybean Planting Bases, ensuring strict raw material traceability from seed to finished powder.
Our subsidiary, Shandong Kawah Oils Co., Ltd. (established in 2014 with 120 million Yuan registered capital), processes 180,000 tons of domestic Non-GMO soybeans annually. Through advanced fractionation techniques, we extract low-temperature food-grade soybean meal, isolated soy protein, soybean oil, and dietary fiber. Our manufacturing facility features the largest single production line in China, powered by a state-of-the-art spray drying tower imported from Dachuanyuan, delivering unmatched consistency in particle size and solubility.
Under Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd), established in 2007 with 100 million Yuan registered capital, we process 500,000 tons of wheat flour annually. Using the industry's most advanced, fully closed tri-canter separation technology, we manufacture high-purity vital wheat gluten, wheat starch A, and wheat starch B.
By Utilizing our starch B and pentosan coproducts for high-grade alcohol and animal feed production, we run a zero-waste, eco-friendly closed-loop production system. This advanced efficiency allows us to mitigate raw material price fluctuations, offering our global B2B buyers highly competitive pricing, secure supply lines, and consistent product quality.
How global food manufacturers integrate our injection proteins into regional products.
For European and North American style cooked hams, injection rates often range between 30% and 80%. Using Isolated Soy Protein 9020/9028 in injection brines helps maintain structural integrity, prevents syneresis (water purging), and provides clean sliceability, allowing processors to achieve uniform, high-speed slicing with minimal waste.
In industrial chicken breasts, turkey rolls, and wings, our injection-type protein acts as a clean binder that enhances tenderness. It integrates seamlessly with phosphate salts to lock moisture inside the delicate muscle fibers of poultry, keeping the meat tender and juicy even under extended heat-lamp warming or reheating.
For meat emulsions requiring stable fat-and-water binding, our dual-purpose Meat & Emulsion Type (9007B-C, 9001BW) proteins form a strong matrix when blended with ground meat. This prevents fat separation during cooking, giving sausages a firm bite, springy elasticity, and a smooth appearance.
In the fast-growing plant-based meat sector, our Vegetarian Type Isolates (9003B, 9005B) offer excellent emulsification and binding properties, mimicking the texture and chewiness of animal proteins. These soy protein isolates provide a high-protein, clean-label foundation for vegetarian burgers, tofu products, and vegan sausages.
Meeting the evolving demands of quality control, sustainability, and market agility.
With rising health consciousness and strict regulations in the European Union and other regions, clean sourcing has become a top priority for B2B buyers. The demand for certified Non-GMO Isolated Soy Protein is growing rapidly. Our rigorous Identity Preservation (IP) system guarantees complete traceability from planting bases to final shipping container, offering our customers a clean-label product that builds consumer trust.
Modern food processing plants are increasingly automated. High-speed multi-needle injection systems require highly consistent ingredient inputs to prevent needle blockages. Variation in powder grind size or solubility can lead to costly downtime. Xinrui Group ensures reliable consistency by using state-of-the-art spray drying systems, allowing processors to run automated lines without interruptions.
Global procurement teams prefer to work directly with manufacturers rather than middlemen to ensure reliable supply. Guanxian Ruichang Trading Co., Ltd. (founded in 2011 with 6 million Yuan registered capital) serves as our dedicated export arm. Ruichang exports over 70% of our group's total production directly to international clients, integrating manufacturing, quality control, and global logistics under one roof to simplify procurement.

We are a group company named Xinrui Group integrating manufacturing and exporting. The manufacturer of soy protein isolate is Shandong Kawah Oils Co., Ltd which produces isolated soy protein 50,000 tons per year. The manufacturer of wheat gluten is Guanxian Xinrui Industrial Co., Ltd. (formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd) which produces vital wheat gluten 30,000 tons per year. The exporter is named Guanxian Ruichang Trading Co., Ltd.
We have HACCP, ISO9001, ISO22000, BRC, HALAL, KOSHER, IP-NON GMO, SGS etc. Other certificates are available as your request.
Industrial injection relies on automated multi-needle systems. If the protein swells and thickens prematurely, it will clog the injection needles, causing uneven brine distribution and production line delays. Our injection-grade isolates are formulated to remain highly fluid in cold brine, dissolving quickly and only geling during the heat cooking phase.
We control our supply chain from the start at our raw material source. We use only Chinese domestic Non-GMO soybeans, processed at our Kawah Oils facility. We run third-party genetic testing on our batches, maintaining full Identity Preservation (IP) documentation for trace verification from planting to export.
Thanks to our integrated operations under Guanxian Ruichang Trading Co., Ltd., we handle logistics directly from our factory floor. Standard orders are prepared and loaded within 10 to 15 days, ensuring prompt shipping to global destinations.
