Founded in 2007, Guanxian Xinrui Industrial Co., Ltd. (formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd) is a high-tech modern enterprise with registered capital reaching 100 million Yuan. Operating under the umbrella of Xinrui Group (est. 2003), we specialize in the deep processing of premium wheat and soy resources into a wide range of highly functional proteins, dietary fibers, and starches.
Our key processing facility utilizes advanced tri-canter separation technology imported from international market leaders. This design enables a fully closed, pristine manufacturing line that yields high-purity vital wheat gluten and soluble wheat protein. Every step of the production process is carefully controlled, ensuring our output value, technology, and compliance stand at the absolute forefront of global standards.
Soluble wheat protein, often referred to as hydrolyzed wheat protein, is an invaluable structural modified plant-based macromolecule. Unlike conventional vital wheat gluten (which forms a highly viscoelastic, water-insoluble rubbery mass), soluble wheat protein undergoes a highly controlled enzymatic hydrolysis process. This reaction reduces the molecular weight distribution of gluten proteins while exposing hydrophilic polar groups, translating to superior water solubility, rapid dispersion, and excellent foaming and emulsifying capacities.
Consumers demand natural, plant-derived products. Soluble wheat protein serves as an excellent alternative to chemical emulsifiers and animal proteins (like casein or whey), functioning beautifully in complex beverage and food matrices.
By employing specific endo- and exo-proteases, our technical route splits peptide bonds at selective sites. This tailors the degree of hydrolysis (DH) to match specific viscosity requirements of global buyers.
The reduction in molecular weight significantly lowers the complexity of the protein. The resulting micro-peptides are easily absorbed, offering high bio-availability for health-focused products.
The global demand for high-performance plant proteins has transitioned from simple bulk purchasing to custom technical specification matching. Multi-national food processors, nutritional brand owners, and cosmetic formulators prioritize suppliers who can offer:
Enhances water binding, dough stretchability, and gas retention. Our soluble proteins improve crumb softness and extend shelf life by reducing starch retrogradation in bread and pastries.
Provides clouding, whipping, and foaming capacity without gritty sediment. Stays highly soluble in acid and neutral beverages, enhancing mouthfeel and protein density.
An exceptional source of glutamine peptides that support post-workout muscle synthesis. Rapid absorption rate makes it ideal for protein powders, shakes, and nutritional bars.
At Xinrui Group, innovation drives our market leadership. Over the next decade, we are expanding our enzymatic technological roadmap to isolate smaller peptide fractions with target bio-activities (e.g. antioxidant properties). Our R&D division is continuously optimizing the tri-canter separation parameters to further reduce waste and optimize energy utilization.
We are also investing heavily in agricultural traceability. Our dedicated Wheat and Non-GMO Soybean planting bases allow us to maintain a full pedigree of the grains we process. From seed selection to the final spray-drying tower, we guarantee full transparency to satisfy the most demanding regulatory frameworks globally.
Through our dedicated trading entity, Guanxian Ruichang Trading Co., Ltd. (established in 2011), we manage the export of over 70% of our group's production capacity directly to global clients. This streamlined approach merges manufacturing expertise with export efficiency, eliminating third-party agent overheads and providing our customers with absolute supply chain transparency.
We are a vertically integrated group company named Xinrui Group that handles both manufacturing and exporting. The production of our isolated soy protein is executed by Shandong Kawah Oils Co., Ltd. (producing 50,000 tons per year). Our vital wheat gluten and soluble wheat protein products are manufactured by Guanxian Xinrui Industrial Co., Ltd. (producing 30,000 tons of vital wheat gluten per year). Export logistics and trade contracts are directly processed through our trade integration arm, Guanxian Ruichang Trading Co., Ltd.
We maintain strict quality control, certified by HACCP, ISO9001, ISO22000, BRC, HALAL, KOSHER, IP-NON GMO, and SGS. Extra documentation, test results, and factory audit reports can be provided as requested.
Vital Wheat Gluten is in its native form, rendering it insoluble in water but highly viscoelastic, which is ideal for dough structuring and baking. Soluble Wheat Protein undergoes controlled enzymatic hydrolysis, breaking the protein structures into smaller peptides that dissolve easily in liquid matrices without losing structural nutritional properties.
Our raw materials are sourced directly from our dedicated Wheat and Non-GMO Soybean planting bases. This ensures full traceability from seedling selection through harvest, milling, extraction, and drying, guaranteeing clean raw materials for all plant protein products.
