Discover high-functionality isolates, functional wheat proteins, and refined circular ingredients tailored for global food manufacturing.
Founded in 2003, Xinrui Group spans a total operational area of more than 1,000 mu. Driven by resource efficiency and process integration, the group has developed a robust circular economy model that bridges clean energy, plant protein science, and global logistics. Xinrui Group manages municipal cogeneration, urban heating, gas supply networks, alongside a highly advanced grain deep-processing architecture that mills over 500,000 tons of wheat flour annually.
By coupling clean energy infrastructure directly with agro-industrial manufacturing, our facility achieves unmatched cost-efficiencies, zero-loss heat recapture, and a vastly reduced carbon footprint compared to standard protein isolates manufacturers globally.
Established in 2014 with a registered capital of 120 million yuan, Shandong Kawah Oils Co., Ltd. stands as a provincial-level leading agricultural industrialization enterprise. We integrate domestic non-GMO soybean plantation, biotechnology R&D, processing engineering, and cross-border trade.
Extracting maximum value from domestic raw non-GMO soybeans, the plant executes a stepwise fractionated extraction process: low-temperature food-grade meal, premium crude oil, highly functional isolated soy proteins, and dietary fiber. The core spray-drying plant is engineered by the prestigious DACHUANYUAN, constituting one of the largest single spray-drying lines in China.
This technical foundation ensures our soy protein isolates possess consistent particle size distributions, superior dispersion properties, and exceptional emulsifying performance.
A deep structural analysis of plant-based macro trends, functional requirements, and supply chains.
The global demand for high-purity protein ingredients has undergone a paradigm shift. Once treated primarily as meat extenders or texture fillers, plant-based proteins—headed by Soy Protein Isolate (SPI)—are now critical functional biomolecules. Environmental policy pressures, ESG mandates for carbon reduction, and consumer leanings toward clean-label, allergen-conscious alternatives have pushed global food manufacturers to scale up plant-protein integrations.
In addition, rising livestock operational costs and supply chains vulnerable to geopolitical fluctuations have highlighted soy protein isolates as a highly cost-effective, nutritionally complete protein reserve. Crucially, the PDCAAS (Protein Digestibility-Corrected Amino Acid Score) of soy protein isolate is 1.0, matching egg whites and dairy casein, making it the most viable large-scale substitute for animal proteins.
Our raw material strategy utilizes exclusively non-GMO soybeans grown locally. As European and North American regulations tighten regarding genetically modified foods and chemical residues, non-GMO status has transitioned from a marketing premium to a regulatory gatekeeper. Backed by Guanxian Ruichang Trading Co., Ltd. (founded in 2011), which manages overseas distribution, more than 70% of our production output is directly exported to major international hubs across Europe, Asia-Pacific, and the Americas.
This integrated structure eliminates intermediary delays and guarantees that full batch trace logs, phytosanitary profiles, and certificates of analysis (COA) are transmitted transparently from our Shandong factory directly to the client's QA departments.
Our production facilities utilize modern separation technology to ensure high protein purity and optimal functionality. For wheat starch and gluten extraction, we utilize state-of-the-art Tri-Canter separation systems. This fully closed loop utilizes centrifuge technology to separate starch phases A and B and wheat gluten while preventing microbial contamination.
For soy protein isolation, Kawah Oils employs a multi-step chemical and physical extraction process designed to protect the native protein structures while removing anti-nutritional factors (such as trypsin inhibitors and off-flavor compounds):
Adapting molecular functional profiles to specific production lines, matrix compositions, and process limits.
Emulsion grades like 9500, 9007B-A, and 9001BW are engineered for thermal stability and high water-and-fat binding capacity. They build stable protein-lipid-water matrices in sausages, hot dogs, and minced products, preventing water syneresis and oil separation during cooking cycles.
Formulations such as 9030 and 9032 feature high dispersion rates, low viscosity at high concentrations, and excellent solubility in neutral beverages, protein drinks, and dry-mix powders. They maintain smooth mouthfeel and clean flavor without chalky textures.
Specialized injection grades like 9020/9026/9028 dissolve quickly in salt/phosphate brines, passing through fine injection needles without clogging. They improve yield, sliceability, and succulence in whole-muscle hams and poultry products.
Isolated soy proteins like 9003B and 9005B are tailored for high gelling capacity. They are designed to interact with calcium/magnesium coagulants or thermal coagulators to form firm, elastic textures in analog cheeses, tofu, and high-protein vegan meals.
Our circular economic model maximizes grain utilization, yielding valuable co-products that support various adjacent industries:
Soy Dietary Fiber (SDF): Derived during the extraction of soy protein isolate, our food-grade SDF offers excellent water-binding capacity and dietary fiber enrichment. It improves crumb structure and moisture retention in baked goods and increases yields in processed meat matrices.
Vital Wheat Gluten (Pellets & Powder): Ground from premium wheat flour via clean Tri-Canter centrifugation, our vital wheat gluten acts as an essential viscoelastic agent for baking and milling applications. The pelletized form (VWG-PS) serves as a durable, nutrient-dense ingredient in aquafeed and pet food formulations.
Superior Grade Ethyl Alcohol (Ethanol 95% / 96%): Utilizing the recovered pentosans and starch B fractions from wheat processing, our advanced fermentation plant produces high-purity ethanol for use in spirits, pharmaceutical bases, sanitizers, and industrial solvents.
We maintain strict adherence to global food safety standards and certifications to ensure seamless international compliance.
Certified under HACCP, ISO9001, ISO22000, BRC, HALAL, KOSHER, and IP-NON GMO schemes.
