WHO WE ARE

Xinrui Group: Integrating High-Output Sourcing & Advanced Refining

Founded in May 2003, Xinrui Group spans a total area of over 1,000 mu. Driven by two decades of industrial growth, the Group has built a diversified and highly efficient circular economy. Our holdings encompass urban cogeneration, regional gas supply, and deep processing of high-grade raw ingredients, reaching an annual output value of 2.8 billion Yuan.

Our operation runs two core primary processing divisions:

Guanxian Xinrui Industrial Co., Ltd. processes 500,000 tons of wheat flour annually, utilizing cutting-edge tri-canter separation technology to manufacture high-yield vital wheat gluten and wheat starch.
Shandong Kawah Oils Co., Ltd. handles the deep processing of 180,000 tons of soybeans annually, using Chinese non-GMO soybean crops to extract low-temperature food-grade soy meal, isolated soy proteins, soy dietary fiber, and non-GMO soy oil.

Export operations are managed through Guanxian Ruichang Trading Co., Ltd., facilitating clean transport, documentation, and compliance support to international buyers, representing over 60%-70% of the Group's production output.

Macro Industry & Formulation Solutions

Applying advanced biochemical research to create functional food-grade soy proteins that optimize emulsion, viscosity, and moisture retention.

Emulsification & Structuring

Our Soy Protein Isolate features high dispersion properties, designed to stabilize high-fat and water matrices in emulsified sausages, reducing oil separation and moisture loss during thermal cycles.

Vegetarian & Alternative Meats

Providing custom vegetarian types (9003B, 9005B) with high gelation strength. These proteins form a dense, fibrous structure resembling muscle tissue, which is essential for plant-based meat formulations.

Beverage Dispersion & Nutrition

Our ultra-fine dispersion proteins (9030, 9032) feature low viscosity and neutral flavor profiles, designed for rapid dissolution in plant milk products, RTD nutritional beverages, and meal replacements.

GLOBAL INDUSTRIAL POSITION

State-of-the-Art Processing: DACHUANYUAN Spray Drying Technology

Shandong Kawah Oils Co., Ltd. operates a high-capacity, single-line spray drying facility. Equipped with a spray drying tower of the DACHUANYUAN design, this plant represents the largest single production line in China for soy protein isolate.

Advanced Production Architecture:

Continuous Defatting: Our facility processes domestic Chinese non-GMO soybeans at low temperatures, preserving the native globulin proteins (7S and 11S fractions).
Acid Precipitation & Alkaline Dissolution: Precise pH adjustments optimize the protein dispersion index (PDI) while removing low-molecular-weight sugars and off-flavors.
Flash Pasteurization & Spray Drying: Micro-nozzle atomization ensures uniform particle size distributions, facilitating rapid reconstitution in liquid systems.

Continuous Processing Sequence

01

Raw Sourcing

100% Identity-Preserved (IP) Non-GMO Soybeans.

02

Low-Temp Extraction

Preserves functional protein fractions without heat denaturation.

03

Purification & Drying

High-atomization spray drying to control density and hydration.

Certified Quality & Regulatory Compliance

Our facilities are verified by international testing bodies, meeting food safety standards across all major export markets.

Identity Preserved (IP) Non-GMO

ISO 9001 & ISO 22000

HACCP Safety Standard

Halal & Kosher

BRC Global Standard

Industrial Innovation & Future Outlook

A structured approach to developing functional, clean-label plant protein isolates and zero-waste manufacturing systems.

Active

Phase 1: Flavor Optimization & Clean Label

Advanced Deodorization & Hexanal Reduction

Applying natural enzyme-assisted rinsing steps and mild extraction to reduce hexanal levels (the compound behind grassy soy flavors). This enables high inclusion rates in dairy alternatives and sensory-sensitive foods without masking agents.

In Progress

Phase 2: Closed-Loop Wheat & Soy Co-Processing

Zero-Effluent Water Recovery & Biomass Conversion

Optimizing our wheat-alcohol circular chain. Co-products like starch B and soluble pentosans are converted into industrial-grade ethanol and animal nutrition, reducing raw material waste and lowering carbon footprints.

Future

Phase 3: High-Moisture Extrusion (HMEC) Texturizers

Targeted Functional Textures & Protein Restructuring

Configuring soy protein fractions (specifically balancing 7S globulin for gelation and 11S for elasticity) to support high-moisture meat-alternative lines, creating realistic steak and poultry textures.

Frequently Asked Questions

Detailed technical, commercial, and operational information for procurement managers, food scientists, and global trade partners.

Are you a trader or manufacturer?

We are an integrated group company named Xinrui Group combining manufacturing and direct export capabilities. The production of isolated soy protein is handled by our subsidiary, Shandong Kawah Oils Co., Ltd, with an annual capacity of 50,000 tons. Our wheat gluten is manufactured by Guanxian Xinrui Industrial Co., Ltd. (formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd), producing 30,000 tons of vital wheat gluten per year. All global trade, export logistics, and customs documentation are managed directly by our dedicated export arm, Guanxian Ruichang Trading Co., Ltd.

What certifications do you have?

Our facilities are certified to international standards, including HACCP, ISO9001, ISO22000, BRC (Global Standard for Food Safety), HALAL, KOSHER, IP-NON GMO (Identity Preserved), and audited by SGS. Custom documentation and local laboratory verifications are available upon request.

How do you guarantee that your soy protein is 100% Non-GMO?

We operate a dedicated Identity Preservation (IP) system from seed selection to final packaging. We source domestic non-GMO soybeans directly from controlled agricultural bases. Every crop batch undergoes PCR testing upon receipt, and we maintain complete segregation in our production lines to prevent cross-contamination.

What is the typical protein concentration on a dry basis?

Our Isolated Soy Protein grades feature a minimum protein concentration of 90% (N x 6.25, dry basis). Moisture content is kept below 7.0%, and ash content is below 6.0%, ensuring optimal purity and ingredient stability.

Can you supply custom viscosity or gelation grades?

Yes, our plant features advanced thermal and enzymatic modification systems. We manufacture specific profiles: high-gelation grades (9007B-C, 9005B) for processed meats and tofu, high-dispersion, low-viscosity grades (9030, 9032) for beverages, and injection grades (9020) for meat processing.
