Discover the massive manufacturing capabilities of Xinrui Group and Shandong Kawah Oils
Established as a global industrial leader, XINRUI GROUP was founded in May 2003 and has expanded to cover an extensive footprint of more than 1,000 mu. With a commitment to clean, high-tech circular production, the group generates an annual output value of 2.8 billion Yuan. Under its umbrella, we integrate urban utilities (including livelihood cogeneration, urban heating, and gas supply) with ultra-scale agricultural deep-processing bases. This vertical integration guarantees massive production output and pricing stability for our global bulk food processing clients.
Formerly known as Guanxian Ruixiang Biotechnology Development Co., Ltd, this branch was founded in 2007 with registered funds of 100 million Yuan. By leveraging advanced tri-canter separation technology imported from premium international machinery brands, the plant runs a completely clean, sealed, and automated processing line. The facility processes 500,000 tons of wheat flour annually, deriving high-grade vital wheat gluten, wheat starch A, and wheat starch B. The residual starch B and pentosan are recycled into alcohol and animal feed production, forming a zero-waste, highly efficient circular economy industrial chain.
Established in 2014 with 120 million Yuan in registered capital, Shandong Kawah Oils Co., Ltd. serves as our primary production arm for high-purity soy products. We utilize premium domestic, strictly Non-GMO soybeans as our starting raw material. Through advanced, stepwise extraction, the facility produces Non-GMO soybean oil, low-temperature food-grade soybean meal, isolated soy protein, and soluble dietary fiber. The core extraction line is powered by the internationally recognized DACHUANYUAN spray drying tower system, giving the facility the single largest production line capacity in China.
To provide seamless export operations, Guanxian Ruichang Trading Co., Ltd. was established in 2011 with a registered capital of 6 million Yuan. Operating as the specialized export gateway of the Xinrui Group, Ruichang handles the direct export of isolated soy protein, vital wheat gluten, soluble dietary fiber, vermicelli, and ethanol. More than 70% of our group's production capacity is shipped directly to overseas food manufacturers, ensuring rapid international delivery, customized customs clearance coordination, and optimized cargo routing.
Why multinational corporations choose Xinrui Group as their long-term clean-label plant protein partner.
We source our soybeans directly from domestic planting bases, maintaining rigorous identity preservation (IP) audits to guarantee 100% Non-GMO status from seed planting to final processing.
With self-owned livelihood cogeneration, steam heating, and natural gas infrastructure within our industrial park, we bypass volatile regional utility prices to offer highly competitive, stable wholesale rates.
Equipped with China's largest single-line spray drying tower (designed by DACHUANYUAN), we comfortably scale production volumes dynamically to meet high-volume seasonal spikes of global giants.
In modern industrial food manufacturing, soy protein isolate is no longer utilized merely as a cheap filler. It has become a key functional additive. Global procurement managers demand strict physical-chemical performance, consistency, and zero contaminants. Our technical team works directly with global R&D departments to provide custom-adjusted soy protein solutions:
| Functional Category | Specific Protein Grade | Primary Industrial Use Cases | Key Functional Advantage |
|---|---|---|---|
| Meat & Emulsion | 9007B-A / 9007B-C / 9500 / 9001BW | Frankfurters, bologna, dynamic emulsified meat loaves, canned luncheon meats. | High water and fat binding capacity; locks in moisture during sterilization. |
| Injection & Brine | 9020 / 9026 / 9028 | Whole muscle hams, poultry breasts, premium injected bacon. | Low viscosity under cold brining, high penetration, leaves no visible needle marks. |
| Tofu & Vegetarian | 9003B / 9005B / 9003BA | Analogue meat patties, plant-based nuggets, traditional soft/firm tofu. | Structured network formation, mimicking the fibrous elasticity of real muscle. |
| Beverage & Dispersion | 9030 / 9032 | Plant milks, meal replacement shakes, infant formula, protein bars. | Exceptional solubility index, smooth mouthfeel, excellent acid stability. |
Providing functional, tailor-made solutions across global culinary and manufacturing sectors.
Designed for clean-label, low-sodium hams and sausages. Our 9020 Injection type dissolves completely into curing brines without precipitating. Once injected into whole muscle tissue, it interacts with meat proteins during tumbling to maximize yield and eliminate purge losses in vacuum packaging.
For tofu manufacturers requiring consistent coagulating patterns, our 9005B grade provides uniform protein cross-linking. In plant-based mock meats, it acts as a binder that retains structural integrity when subjected to extreme freezing, thawing, and subsequent frying.
In high-protein meal replacements, typical plant proteins suffer from sedimentation and sandy textures. Our dispersion-optimized 9030 grade features high nitrogen solubility (NSI), guaranteeing a velvety, clean liquid profile without grit or bitter aftertastes.
At a molecular level, our isolated soy proteins are extracted through aqueous enzymatic treatment, followed by isoelectric precipitation and spray drying. The resulting powder consists of more than 90% protein (dry basis), primarily composed of globulins (7S glycinin and 11S beta-conglycinin). The balance between these fractions dictates the gelation, water-holding capacity, and viscosity of the final food matrix. Under the thermal shear of food extruders, these globulins denature and realign into parallel fibrils, mimicking animal muscle fibers to perfection. Our DACHUANYUAN spray drying towers carefully preserve the native structure of these proteins, ensuring optimal performance for global food scientists.
Ensuring complete peace of mind through international safety standards and third-party audits.
To support global supply chains, our factory conforms to the world's most demanding food safety protocols. We maintain an independent Quality Control department equipped with high-performance liquid chromatography (HPLC), gas chromatography, and real-time PCR testing to monitor GMO traces and ensure pesticide-free batches. Our compliance certificates include:
