The global shift toward plant-based nutrition has accelerated rapidly, moving from niche dietary preferences to mainstream macromolecular food engineering. At the core of this transition is Isolated Soy Protein (ISP), a highly refined phytoprotein containing not less than 90% protein dry weight. Food processing industries globally demand functional, highly emulsified, and dispersible protein solutions to address sensory expectations, clean-label requirements, and nutritional parameters.
By extracting proteins from low-temperature food grade soybean meal, our refinery lines partition functional storage proteins (primarily glycinin and beta-conglycinin). These isolates act as structural blocks, moisture managers, and fat binders in complex colloidal matrices. With the global demand for plant-based alternatives increasing at a double-digit compound annual growth rate (CAGR), having a secure, reliable supply chain of raw materials is essential for manufacturing stability.
Since our inception in 2003, Xinrui Group has built a circular agricultural processing network. We operate multiple production sites that connect crop cultivation, deep biotechnology refining, energy cogeneration, and global trade networks.
Established in 2014 with a registered capital of 120 million Yuan, Shandong Kawah Oils Co., Ltd. is our agricultural processing facility, processing over 180,000 tons of domestic NON-GMO soybeans annually. Kawah Oils manages the production chain from raw bean cleaning, oil extraction, to low-temperature meal production, culminating in high-purity protein extraction.
Founded in 2007 with a registered capital of 100 million Yuan, Guanxian Xinrui Industrial Co., Ltd. (formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd) forms our wheat processing division. Processing 500,000 tons of wheat flour per year, this plant produces Vital Wheat Gluten, Wheat Starch A, and Wheat Starch B.
Established in 2011 with a registered capital of 6 million Yuan, Guanxian Ruichang Trading Co., Ltd. serves as the direct export portal of the Xinrui Group. Ruichang Trading exports isolated soy protein, vital wheat gluten, soluble dietary fiber, vermicelli, and ethanol directly to international buyers.
Our isolated soy protein is processed using advanced physical and chemical refining techniques designed to preserve the functionality of the native protein structure.
Raw degreased soybeans are alkalized to solubilize globulins, followed by precision acid precipitation at pH 4.5. This isolates the high-purity protein fractions from soluble carbohydrates and dietary fibers.
Using one of China's largest spray drying towers, neutralized protein slurry is dried rapidly under controlled temperatures. This preservation step maintains the functional properties of the protein powder, including dispersion, solubility, and hydration.
Through controlled thermal shear and enzymatic modifications, we customize the ratio of 7S (beta-conglycinin) and 11S (glycinin) globulins. This process allows us to tailor the protein for specific requirements, such as high-gelation meat binding or low-viscosity beverage dispersion.
Different food matrices require specific protein behaviors. We refine and calibrate our isolates into distinct application types to optimize functional performance.
For processed meats, hot dogs, and canned goods, we offer the 9001BW/9001B-Y/9000 and 9007B-A/C series. These models are engineered to build strong protein networks that bind free water and emulsify lipids, maintaining structure during thermal processing.
Our 9020/9026/9028 injection-type proteins are designed for hams, bacon, and poultry breast processing. These isolates dissolve quickly without clogging injection needles.
For traditional tofu and plant-based meat alternatives, we supply 9003B and 9005B. These isolates provide the necessary structural framework to replicate animal muscle fibers when combined with Vital Wheat Gluten.
For nutritional shakes, dairy alternatives, and meal replacements, we supply the dispersion-focused 9030 and 9032 series. These isolates dissolve smoothly without grittiness.
Xinrui Group manages supply chain risks through geographical placement, industrial integration, and raw material controls. Situated in Guanxian, Shandong, we operate near key domestic NON-GMO soybean agricultural regions. This allows us to source raw materials with full traceability (IP Non-GMO status) while minimizing transportation costs and risks.
Our facilities maintain a range of internationally recognized certifications to ensure products meet food safety and religious dietary requirements across global markets.
