Select from our key high-purity non-GMO isolated soy proteins and plant ingredients, customized for optimal water-binding capability, gelation strength, and nutritional profile.
Xinrui Group represents a highly integrated circular economy industrial model, utilizing advanced raw ingredient sourcing and European-tier manufacturing standards to secure continuous, high-volume production for international food manufacturers.
The global shift toward plant-based alternatives and clean-label functional formulations has elevated the role of isolated soy protein (ISP) from a simple filler to a key structural element. Soy protein isolate is prized for containing all nine essential amino acids in concentrations that mimic high-quality animal proteins. In modern meat processing, emulsion preparation, dairy alternatives, and nutritional formulations, the demand for non-GMO high-purity protein fractions has grown exponentially.
Buying in standard bulk packages like Soy Protein Powder 20kg bags is critical for major operations. It represents a balance between ease of manual handling, optimization of automated bulk handling, moisture preservation, and logistics efficiency. Commercial recipes require raw ingredients to remain stable and functional through ocean shipping, prolonged storage, and high-shear industrial mixing. Our integrated industrial plants solve these problems by using advanced spray drying technology and clean-closed production circuits.
For large-scale food processors, the 20kg multi-layer kraft paper bag with a PE inner liner is the global standard. This design provides several distinct operational advantages:
The hermetically sealed PE inner film prevents water vapor transmission, which is crucial for preventing protein clumping and degradation over long transit times.
Optimized bag dimensions allow for secure stacking on standard pallets, maximizing container space. This lets us load up to 12 metric tons per 20' FCL (without pallets) or 10 metric tons (with pallets).
The 20kg weight allows operators to safely handle and dose bags without needing heavy lifting equipment, keeping batch compounding lines agile.
Our processing site, Shandong Kawah Oils Co., Ltd. (subsidiary of Xinrui Group), is a key agricultural processor. Our facility is designed around a sustainable, circular economy loop, processing 180,000 tons of domestic non-GMO soybeans every year. We refine our raw materials in a step-by-step process: first extracting crude non-GMO soybean oil, then producing food-grade low-temperature white flakes, which are finally processed into isolated soy protein and soy dietary fiber.
The core of our soy protein isolate quality is our spray drying process. We run a single-line spray dryer from DACHUANYUAN, which is the largest single-line system of its type in China. This technology provides precise control over particle size, hydration properties, and protein stability.
By adjusting temp zones and nozzle pressures, we can customize the physical properties of our protein powders. This allows us to produce high-gel formulas like 9007B-C, quick-dispersing drinks like 9030, and high-emulsion grades like 9001BW, meeting the diverse demands of food processing industries worldwide.
In addition to our soy operations, Guanxian Xinrui Industrial Co., Ltd. processes 500,000 tons of wheat flour annually. Our facility uses advanced, imported European tri-canter separation technology for wet wheat processing.
This closed loop separates starch and protein fractions cleanly, keeping our Vital Wheat Gluten (both powder and pellet forms) pure and functional. The residual pentosan and starch B fractions are routed directly into our integrated ethanol and feed loops, lowering production waste and securing cost stability for our customers.
Because soy protein isolates function differently depending on the application, we do not believe in one-size-fits-all products. We have developed specialized lines tailored to specific food systems and processing conditions:
Designed for processed meats, sausages, and hot dogs. Grades like 9007B-C, 9001BW, and 9500 form strong, heat-stable protein networks. They bind oil and water efficiently, helping to reduce cook shrink and maintain texture.
Designed for instant drink mixes, ready-to-drink (RTD) beverages, and nutritional powders. Our dispersion grades, such as 9030 and 9032, dissolve quickly without clumping or gritty textures, even at low shear.
Designed for traditional tofu, meat alternatives, and vegetarian foods. Grades like 9005B and 9003B are optimized for high gelation strength, helping producers control firm textures and keep yields consistent.
Designed for injecting whole cuts of meat, hams, and poultry. Grades like 9020, 9026, and 9028 have low viscosity and stay suspended in brine, helping processors inject meat evenly without blocking needles.
Established in May 2003, Xinrui Group has grown to span more than 1,000 mu, housing an integrated food ingredient business. The Group coordinates local combined heat and power systems, municipal heating networks, natural gas infrastructure, and high-volume raw crop processing plants.
Our global trade division, Guanxian Ruichang Trading Co., Ltd. (founded in 2011 with 6 million Yuan registered capital), acts as our direct export channel. Ruichang Trading exports isolated soy protein, wheat gluten, soluble dietary fiber, and ethanol directly from our factories to overseas customers. Over 60% to 70% of our group's total production capacity is exported, helping us coordinate manufacturing and logistics for global buyers.
Maintaining strict quality control is essential for global food ingredients. Our manufacturing plants operate under strict Hazard Analysis Critical Control Point (HACCP) programs and hold multiple international food safety and product certifications.
Our supply chains undergo regular third-party audits to verify trace IP (Identity Preserved) status, ensuring our soybeans remain non-GMO from planting to processing.

Technical details for procurement managers and food scientists evaluating our soy protein isolates.
We are a fully integrated group company named Xinrui Group, bringing together manufacturing and international export divisions. Under this structure, Shandong Kawah Oils Co., Ltd. operates as our soy protein isolate manufacturing facility, producing 50,000 tons of isolated soy protein annually. Guanxian Xinrui Industrial Co., Ltd. (formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd) produces 30,000 tons of vital wheat gluten per year. All direct global sales are handled through our export division, Guanxian Ruichang Trading Co., Ltd.
Our facilities hold several international certifications, including HACCP, ISO9001, ISO22000, BRC (British Retail Consortium), HALAL, KOSHER, and IP-NON GMO (Identity Preserved) from SGS. We can also provide other specific health certificates, phytosanitary documents, and laboratory analyses upon request.
Our standard isolated soy protein (ISP) maintains a minimum protein level of 90% on a dry basis. For special premium lines, we can hit 92% or higher. This high concentration is achieved by dissolving and separating non-protein components from low-temperature de-fatted soy flakes, ensuring a pure, functional protein product.
We manage our raw materials through an Identity Preserved (IP) system. This program tracks our soybeans from the seed supply and planting stages through harvest, factory reception, processing, and packaging. We run regular PCR tests in our quality control laboratories and use dedicated, clean containers to prevent cross-contamination.
Yes. We can customize the physical properties of our proteins by adjusting our spray drying parameters. For meat emulsions, we optimize the process for high gel strength and water absorption. For beverages, we adjust the process to keep viscosity low and dispersion rates high, preventing sedimentation in the final drink.
Our 20kg bulk soy protein powder has a shelf life of 12 months when stored in original, unopened packaging. To maintain performance, keep the bags in clean, dry warehouses below 25°C and at a relative humidity under 60%. Do not store products near strong odors or volatile chemicals.
