Xinrui Group: Integrating Agro-Industrial Processing

Pioneering High-Purity Proteins and Starches from Vertically-Integrated Production Ecosystems

Scale & Legacy

Established in May 2003, Xinrui Group spans over 1,000 mu. The group is home to major industrial components including regional cogeneration, urban heating, municipal gas utility supplies, and large-scale plant processing facilities. The annual group industrial output value reaches 2.8 billion Yuan, driven by advanced processing infrastructure and global trade integration.

Wheat Circular Value Chain

Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd) processes 500,000 tons of wheat flour annually. Utilizing advanced European tri-canter separation systems in a closed sanitary loop, we extract Vital Wheat Gluten, Wheat Starch A, and Wheat Starch B. Starch B and pentosan co-products feed directly into ethanol and animal nutrition units, eliminating waste.

Non-GMO Soy Processing

Shandong Kawah Oils Co., Ltd., founded in 2014, processes 180,000 tons of domestic Non-GMO soybeans annually. We systematically refine beans into Non-GMO soy oil, low-temperature food-grade soy meal, Isolated Soy Protein (ISP), and Soy Dietary Fiber (SDF). The facility integrates state-of-the-art spray drying towers from DACHUANYUAN, boasting one of China's largest single-line capacities.

Supply Chain Infrastructure & Production Technology

Unrivaled Processing Scale Combined with Precise Molecular Control for Optimal Functional Performance

Vertically Integrated Circular Economy Model

Operating in the agricultural processing industry requires both resource resilience and environmental accountability. At Xinrui Group, we have built a closed-loop circular economy industrial chain.

When raw wheat enters our facility, it undergoes wet milling using European-sourced tri-canter separation. Instead of discarding the secondary streams, we convert Wheat Starch B and pentosan compounds into high-grade industrial and food-grade ethyl alcohol (ethanol) and protein-rich animal nutrition feeds. Similarly, our non-GMO soybean crushing plant extracts oil, and transforms the protein-rich cake into food-grade low-temperature soy meal, which acts as the feedstock for Isolated Soy Protein (ISP) and Soy Dietary Fiber (SDF).

Direct-to-Buyer Factory Export Integration

To streamline global procurement, the group established Guanxian Ruichang Trading Co., Ltd. in 2011. Ruichang acts as the direct factory-to-buyer export arm, sending over 70% of the group’s total production capacity straight to international buyers in over 60 countries. This eliminates intermediary markups, guarantees origin authenticity, and provides direct technical communication lines between our plant scientists and our customers' R&D teams.

Global Sourcing Requirements, Compliance, and Industry Trends

How We Support International Food Brands and Multi-National Purchasing Networks

1. Localization Support & Regulatory Compliance

International food processing plants operate under strict sanitary rules. We address this by providing fully documented IP-Non-GMO traceability, ensuring that no cross-contamination occurs from farm fields to finished product packaging. Our logistics team handles phytosanitary licensing, certificate of analysis (COA) matching, customs declarations, and custom packaging labeling to fit regional markets (EU, North America, LATAM, APAC).

Whether it is meeting heavy metal limits for the European market or low-dust specifications for North American automated dumping stations, we adapt our processing parameters to ensure seamless local operation.

2. China Factory Supply Chain Advantages

Sourcing isolated soy protein directly from a Chinese processing giant offers distinct advantages:

  • Economies of Scale: High processing volume ensures stable pricing, even during global raw materials market fluctuations.
  • Raw Material Security: We source premium Non-GMO soybeans from dedicated local farming bases, securing supply continuity.
  • Energy Self-Reliance: Our integrated municipal cogeneration plant guarantees uninterrupted steam and electricity supplies for our spray drying towers.

Global Market Trends: Plant-Based Transition & Clean Labeling

The food industry is shifting toward cleaner ingredient labels and sustainable proteins. Soy protein isolate remains the choice for meat alternatives and functional foods due to its complete amino acid profile, high digestibility (PDCAAS score of 1.0), and reliable mechanical texturizing performance.

Our continuous research focuses on reducing naturally occurring phytates, improving flavor profiles, and increasing water binding capacities without using chemical additives. This supports clean label formulations that appeal to health-conscious consumers worldwide.

Frequently Asked Questions

Technical, Commercial, and Logistical Inquiries Answered by Our Chemical Engineers and Global Sales Directors

Are you a trader or manufacturer?
We are a vertically integrated group company named Xinrui Group that handles both manufacturing and direct exports.
  • Shandong Kawah Oils Co., Ltd. produces our Isolated Soy Protein (ISP) with an annual capacity of 50,000 tons.
  • Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd) produces our Vital Wheat Gluten with an annual capacity of 30,000 tons.
  • Guanxian Ruichang Trading Co., Ltd. handles global trade and export services, working directly under group management to manage shipment coordination.
What quality certificates do you have for international markets?
We maintain a robust compliance portfolio including HACCP, ISO9001, ISO22000, BRCGS (Global Standard for Food Safety), HALAL, KOSHER, and IP-NON GMO identity preservation certificates. We also collaborate with SGS for independent, batch-specific quality verification upon buyer request.
How do you guarantee that your soy protein products are Non-GMO?
We source our raw yellow soybeans from dedicated domestic planting bases that use only Non-GMO seeds. We utilize a strict Identity Preservation (IP) management system. This ensures separate collection, storage, and processing routes, preventing cross-contact with GMO materials. Each production batch undergoes PCR testing before warehouse release.
What is the difference between Emulsion, Injection, and Dispersion type proteins?
These designations correspond to differences in viscosity, gelling behavior, and oil-binding capacity:
  • Emulsion Type: Highly functional protein structure designed to bind large volumes of water and fat under high-speed mechanical shearing. Perfect for emulsified meats.
  • Injection Type: Low viscosity at cold temperatures, allowing it to pass through injection nozzles easily. It forms a stable gel inside meat fibers during cooking.
  • Dispersion Type: Highly soluble and fast-dispersing in aqueous environments, making it ideal for high-protein powdered beverages and food shakes.
What are the typical lead times and MOQ specifications for wholesale delivery?
Our standard Minimum Order Quantity (MOQ) is 1 FCL (Full Container Load), typically containing 20 metric tons. The standard shipping lead time is 15-20 days from order confirmation, allowing for batch inspection and customs clearance.
Can you supply custom bag sizes or private label packaging?
Yes, we offer flexible packaging options. The standard packaging format is 20kg or 25kg multi-layer kraft paper bags with inner PE liners. We can also provide 1-metric-ton bulk super sacks or custom-printed OEM paper bags to match your brand requirements, subject to specific volume commitments.
Do you offer free samples for pilot plant testing?
Yes, we supply sample quantities (typically 500g to 2kg) to food laboratories and R&D departments for evaluation. Please contact our trade department with your target specifications (gel strength, viscosity, NSI) to request a sample batch.
