The global demand for plant-based proteins has experienced a paradigm shift over the past decade. Food manufacturers, meat processing enterprises, and beverage formulators are seeking highly functional raw materials to satisfy the rapidly expanding consumer preferences for clean-label, allergen-friendly, and sustainable protein sources. The 20kg bag packaging configuration has emerged as the definitive industrial standard for shipping and material handling across global supply chains.
From an operational standpoint, 20kg bags offer the ideal balance between physical handling safety compliance (limiting worker strain under standard warehouse operations) and automated batching compatibility. Large-scale recipe configurations in meat emulsification, protein fortification, and baking lines are structured around modular ingredient additions, where 20kg represents a repeatable, precise unit block. Furthermore, compared to bulk supersacks, 20kg multi-layer kraft paper bags with inner PE liners provide exceptional moisture barriers, preserving the structural integrity and dispersion characteristics of sensitive powder fractions during transoceanic shipping.
Established in May 2003, Xinrui Group has developed into a diversified industrial powerhouse covering over 1,000 mu. Under its integrated corporate umbrella, the group manages municipal cogeneration, urban heating, and gas supply systems, which actively feed energy into its core agri-processing subsidiaries: Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd) and Shandong Kawah Oils Co., Ltd.. The group achieves a massive annual output value of 2.8 billion Yuan.
Our wheat processing ecosystem is designed around a zero-waste, deep-processing circular economy model. Processing 500,000 tons of wheat flour annually, the plant outputs high-grade vital wheat gluten, wheat starch A, and wheat starch B. The starch B and pentosan fractions are subsequently recycled to manufacture industrial bio-ethanol and high-nutrition animal feed. By deploying the world's most advanced tri-canter separation technology for wheat gluten extraction, we maintain completely closed and sanitized process loops that surpass national and international peers in purity, consistency, and yield.
The functionality of isolated plant protein powder relies heavily on processing parameters. At Shandong Kawah Oils Co., Ltd. (established in 2014, with a registered capital of 120 million Yuan), we utilize strictly domestic Non-GMO soybeans to extract premium food-grade soybean oil, low-temperature soybean meal, isolated soy protein (ISP), and soy dietary fiber (SDF). The core step in protein extraction involves solubilizing the proteins under mild alkaline conditions, removing the insoluble fiber fraction via advanced centrifugation, and subsequently precipitating the proteins at their isoelectric point (pH 4.5).
To dry the protein isolate without causing thermal denaturation, we utilize the state-of-the-art DACHUANYUAN spray drying tower system. As the largest single production line in China, this drying system controls air volume, inlet temperatures, and atomization pressures to create particles with ideal dispersion, hydration, and density parameters. The resulting protein isolates exhibit excellent water absorption, emulsification, and gel strength, which are essential for applications in processed meats, dairy replacements, and nutritional beverages.
| Functional Category | Common Code & Type | Core Application | Primary Technical Characteristics |
|---|---|---|---|
| Meat & Emulsion Type | 9007B-C, 9001BW, 9001BH, 9006B, 9500 | Sausages, hams, canned meats | High gel strength, fat emulsification, water-binding capacity. |
| Meat & Injection Type | 9020, 9026, 9028 | Whole muscle hams, poultry injection | Low viscosity, high dispersibility, maintains texture after brine injection. |
| Tofu & Vegetarian Type | 9003B, 9003BA, 9005B | Analog meats, traditional tofu, vegetarian patties | Excellent fibrous texture formation, high thermal stability. |
| Beverage & Dispersion Type | 9030, 9032 | Protein shakes, meal replacements, dairy products | Instant solubility, minimal sedimentation, neutral taste profile. |
| Soy Dietary Fiber | SDF | Dietary fiber enrichment, baked goods, low-calorie diets | High water holding capacity, smooth texture addition, dietary health. |
| Vital Wheat Gluten | VWG-P, VWG-PS (Powder & Pellets) | Baking, noodle processing, aquafeed | High viscoelasticity, gas retention, structure enhancer. |
Our 9007B-C and 9020 series isolated soy proteins are specifically engineered to optimize yield and texture in meat systems. By creating stable oil-in-water emulsions, they prevent fat rendering and water separation during thermal processing, improving product sliceability and texture.
Deploying high-elasticity Vital Wheat Gluten (VWG-P) enhances flour strength and gas retention in bread and noodle formulations. Combined with Soy Dietary Fiber, this allows industrial bakeries to achieve high-fiber claims without compromising dough volume or crumb texture.
Our 9030 and 9032 dispersion series dissolve quickly in aqueous systems. They exhibit low viscosity and high solubility profiles, reducing grittiness and maintaining suspensions in ready-to-drink (RTD) meal replacements and powdered nutritional beverages.
Exporting ingredients globally requires strict regulatory compliance. Guanxian Ruichang Trading Co., Ltd. (founded in 2011 with 6 million Yuan of registered capital) serves as our dedicated export arm, directly handling shipping and customs compliance for our manufacturing facilities. Over 60% to 70% of our group's production capacity is exported directly to global buyers across Europe, the Americas, Southeast Asia, and the Middle East.
Our quality control processes ensure compliance with international standards. We maintain a robust certification suite, including HACCP, ISO9001, ISO22000, BRC, HALAL, KOSHER, and IP-NON GMO. We offer complete batch traceability, beginning at our dedicated Non-GMO soybean cultivation bases, continuing through low-temperature crushing, and concluding with final product packaging in 20kg bags. Third-party testing (SGS) is available for every shipment to verify protein content, heavy metal compliance, microbiological counts, and genetic purity.

We are an integrated group company named Xinrui Group that combines manufacturing and exporting. Our subsidiary, Shandong Kawah Oils Co., Ltd., produces 50,000 tons of isolated soy protein per year. Our wheat processing subsidiary, Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd), produces 30,000 tons of vital wheat gluten per year. All international trade operations are handled directly by our export arm, Guanxian Ruichang Trading Co., Ltd..
We hold a comprehensive set of international certifications, including HACCP, ISO9001, ISO22000, BRC (Global Standard for Food Safety), HALAL, KOSHER, and IP-NON GMO. We can also coordinate additional testing through SGS or Intertek to meet regional entry requirements.
Our 20kg bulk packaging consists of multi-wall, heavy-duty kraft paper bags with a heat-sealed interior polyethylene (PE) liner. This configuration provides resistance to moisture absorption, oxygen ingress, and mechanical tearing during container transport. We offer slip-sheet or palletized packing with stretch-wrapping for secure containerized transport.
When stored under cool, dry conditions (temperatures below 25°C and relative humidity below 60%), our isolated soy protein and vital wheat gluten maintain their functional properties for 12 to 24 months from the manufacturing date. We recommend keeping packages sealed until use to prevent moisture pickup.
Yes. Through Shandong Kawah Oils, we can adjust processing parameters during the extraction and spray-drying phases. This allows us to target specific gel indexes, viscosities, and emulsification ratios (such as 1:5:5 or 1:6:6 water-to-fat ratios) to match the requirements of your meat, bakery, or beverage production lines.
We operate a strict Identity Preservation (IP) system from seed selection to processing. Our soybean raw materials are sourced from controlled Non-GMO domestic cultivation bases. Every batch undergoes PCR testing to confirm the absence of genetically modified DNA sequences before entering the production facility.
With our integrated manufacturing plants (processing 180,000 tons of soybeans and 500,000 tons of wheat flour annually), we maintain consistent inventory reserves. Typical lead times for container-load orders (FCL) are 14 to 21 days from order confirmation, depending on customization and destination port requirements.
