Premium agricultural raw materials sourced directly from our proprietary planting bases, processed via state-of-the-art wet milling and extraction lines.
Established in May 2003, XINRUI GROUP has built a highly diversified and vertically integrated agricultural industrial ecosystem. Spanning an expansive area of more than 1,000 mu, the Group has established modern business units including people's livelihood cogeneration, urban heating, gas supply, and deep processing sectors. With an annual output value reaching 2.8 billion Yuan, the group stands as a key regional anchor for agro-biotechnology.
At the heart of our operations, GUANXIAN XINRUI INDUSTRIAL CO., LTD. (formerly known as GUANXIAN RUIXIANG BIOTECHNOLOGY DEVELOPMENT CO., LTD) was established in 2007 with registered capital of 100 million Yuan. The facility annually processes 500,000 tons of high-grade wheat flour, deriving vital wheat gluten, wheat starch A, wheat starch B, pentosan, and downstream derivatives, establishing a model for circular green manufacturing.
To maintain structural and functional dominance, Guanxian Xinrui Industrial Co., Ltd. imported the industry's most advanced tri-canter separation technology for vital wheat gluten processing. The entire manufacturing process runs on a closed, fully sanitized loop to eliminate cross-contamination.
Complementing our grain processing capabilities, SHANDONG KAWAH OILS CO., LTD. was founded in 2014 with a registered capital of 120 million Yuan. As a provincial leading agricultural industrialization enterprise, Kawah Oils processes 180,000 tons of NON-GMO soybeans annually. The company uses domestic NON-GMO raw materials to systematically extract high-purity soybean oil, low-temperature food-grade soy meal, isolated soy protein, and dietary fiber, featuring a spray drying tower from DACHUANYUAN which represents the largest single production line in China.
Global production infrastructure driven by circular economy efficiency and rigorous scientific management.
A technical guide on how enzymatic hydrolysis controls peptide chain lengths to optimize functional performance in personal care, cosmetics, and nutritive formulations.
Utilizing proprietary protease cocktails to break peptide bonds, yielding consistent molecular weight distributions. Standardized molecular weight ranges from 500 Da to 5000 Da ensure optimal bio-affinity and solubility.
Low-molecular-weight oligopeptides (<1000 Da) deeply penetrate hair shafts to repair internal structures. High-molecular-weight proteins (>3000 Da) form a protective, moisture-retentive film on the cuticle surface.
Rich in glutamic acid, proline, and cystine, which are critical for disulfide bond cross-linking. Hydrolyzed wheat protein actively reinforces hair elasticity, reduces static charge, and boosts tensile strength.
The next generation of plant-based functional ingredients requires tailored biochemical characteristics. At Xinrui Group, our R&D initiatives focus on targeted molecular customization. Traditionally, hydrolyzed wheat protein (HWP) served as a generic film-former in cosmetics or a volume enhancer in food systems. Today, our research is refining enzymatic cleavage processes to synthesize targeted peptides that possess specific bioactive properties. By manipulating hydrolysis time, temperature, and enzyme concentration, we can precisely target the peptide bond profile of wheat gluten.
Looking forward, our technical roadmap aims to integrate advanced artificial intelligence modeling to predict peptide functionality based on raw material batch profiles. This system will allow us to continuously refine the solubility index, stability under extreme heat, and compatibility with surfactant formulations. For cosmetic applications, our future molecular lineages focus on maximizing the content of sulfur-containing amino acids to closely match the keratin structure of human hair, offering a vegan alternative to animal-derived keratin.
The manufacturing footprint of Guanxian Xinrui Industrial Co., Ltd. demonstrates how high-throughput processing can coexist with resource efficiency. Our modern plant incorporates a closed-loop "Circular Economy" model. The wheat flour (processed at a rate of 500,000 tons per year) undergoes wet separation via high-performance tri-canter systems.
We provide raw material solutions for diverse global industries. In the personal care sector, our hydrolyzed wheat proteins offer anti-irritant and conditioning benefits in shampoos, body washes, and facial cleansers.
In the food processing industry, our functional proteins function as binders, texturizers, and emulsifiers. By coordinating research across our grain milling facilities and Shandong Kawah Oils' non-GMO soybean plants, we offer customized protein blends. These combinations help manufacturers optimize sensory profiles, crumb structure, and water absorption in plant-based meats, dairy alternatives, and baked goods.
From wheat gluten to non-GMO soy protein isolates, discover our comprehensive range of high-performance proteins.
To coordinate international commerce and distribution, GUANXIAN RUICHANG TRADING CO., LTD. was founded in 2011 with a registered capital of 6 million Yuan. Operating as the direct commercial and export hub of the Xinrui Group, Ruichang Trading manages the international distribution of soy protein isolate, vital wheat gluten, soluble dietary fiber, vermicelli, and ethanol.
By exporting more than 70% of the Group's production capacity directly to overseas customers, we ensure transparent pricing, direct support, and stable logistics. This setup bridges the gap between agricultural processing and global trade, ensuring efficient delivery to major international ports.
At SHANDONG KAWAH OILS CO., LTD., we utilize domestic NON-GMO soybeans to produce high-purity oil, low-temperature soybean meal, and isolated soy protein. Our spray drying technology from DACHUANYUAN represents the largest single production line in China.
This scale allows us to support clean-label food manufacturers. Whether you require emulsifiers for processed meats or soluble proteins for beverage dispersions, our integrated plants deliver consistent functionality across production batches.
