A comprehensive overview of Xinrui Group's vertically integrated processing power, state-of-the-art technological infrastructures, and circular business model.
Established in May 2003, XINRUI GROUP has grown to occupy a vast footprint exceeding 1,000 mu. Driven by diversified agricultural industrialization, the group comprises several key subsidiaries: GUANXIAN XINRUI INDUSTRIAL CO., LTD. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd), SHANDONG KAWAH OILS CO., LTD., and dedicated wheat and non-GMO soybean planting bases. Together, the group coordinates energy generation, urban heating, municipal gas supply, and ultra-high capacity food and feed ingredient manufacturing, generating an annual industrial output value of 2.8 billion Yuan.
Our wheat processing capabilities at Guanxian Xinrui Industrial Co., Ltd. stand at a staggering 500,000 tons of wheat flour annually. Utilizing the advanced, imported European tri-canter separation technology, we operate a completely clean and closed production system to isolate wheat gluten, starch A, and starch B. Within our circular economy layout, starch B and pentosans are directly funneled into the production of high-grade bio-ethanol and specialized animal feeds. This eliminates production waste and guarantees a highly reliable supply chain.
Shandong Kawah Oils Co., Ltd., established in 2014, specializes in processing 180,000 tons of domestic Non-GMO soybeans annually. Integrating cultivation, seed research, deep processing, and export control, the facility utilizes step-by-step extraction to isolate Non-GMO soybean oil, low-temperature food-grade soybean meal, isolated soy protein, and soy dietary fiber. Our facility features a state-of-the-art spray drying tower from DACHUANYUAN, boasting one of the largest single-line production capacities in China.

Transitioning from commodity feed grains to functional plant protein isolates: How our customized protein solutions address global veterinary and aquaculture challenges.
Modern aquaculture relies heavily on stable water conditions and highly digestible protein sources to minimize nitrogenous waste. Our Vital Wheat Gluten (VWG-P/VWG-PS) provides excellent viscoelastic binder properties. This enhances pellet stability in water, ensuring feed does not disintegrate before ingestion.
Simultaneously, our food-grade Isolated Soy Proteins (9001BW/9000 series) deliver a rich amino acid profile to replace premium fishmeal, reducing feed conversion ratios (FCR) in shrimp, salmon, and marine carnivorous fish.
Young piglets suffer from immunological stress post-weaning, often triggered by the antigen proteins glycinin and beta-conglycinin found in commodity soybean meals.
Shandong Kawah Oils' Isolated Soy Protein (ISP) isolates these protein structures, lowering anti-nutritional factors (ANFs) to trace levels. This significantly reduces gut mucosal inflammation, prevents post-weaning diarrhea, and enhances the daily weight gain of weaning piglets.
Our wheat starch A and B fractions provide superior gelatinization indexes necessary for pellet durability. Using these starches as carbohydrates in poultry starter diets ensures consistent structural integrity of the feed.
This prevents nutrient segregation during transit and increases voluntary intake of critical high-potency micro-ingredients in broiler chicks.
Premium dog and cat dry kibbles, along with wet pet foods, require excellent emulsification properties. Our isolated soy proteins (Meat & Emulsion type like 9007B-A / 9007B-C) act as multi-functional emulsifiers and texture-modifying agents.
They bind water and fats, producing a highly desirable meat-like chunk texture and improving overall palatability while ensuring complete nutritional profiles.
Continuous R&D initiatives pointing towards micro-molecular enzymolysis, next-generation non-allergenic proteins, and digital production efficiency.

As global animal nutrition transitions from crude protein concentration to precision amino acid digestibility, Xinrui Group is spearheading research in bio-enzymatic cleavage technologies. Our goal is to commercialize low-molecular-weight peptides that bypass normal digestive constraints, enabling direct intestinal absorption in immunocompromised animals.
Our roadmap focuses on eliminating anti-nutritional factors (ANFs). By integrating specialized, target-specific enzymes into our low-temperature soybean meal extraction line, we are reducing oligosaccharide, lectin, and trypsin inhibitor counts to near zero. This optimization allows aquaculture and swine producers to replace expensive animal proteins completely.
Additionally, we are investing in advanced membrane separation systems to extract isolated soy proteins at low temperatures. This method retains the natural structure of the protein molecules, resulting in better water binding and emulsification. We are also testing automated online particle sizing to ensure consistent dispersion profiles.
How our vertically integrated infrastructure mitigates geopolitical and climate-related supply chain vulnerabilities.
Operating our own cogeneration power plants, urban heating systems, and municipal gas grid guarantees uninterrupted factory operations during winter energy spikes, ensuring consistent production schedules.
Utilizing China's largest single-line spray drying tower capacity ensures high-throughput batch consistency and excellent physical flow properties, which reduces dust during automated feed loading.
Guanxian Ruichang Trading Co., Ltd. handles direct exports from our factories, bypassing middle-man trading companies. This ensures clear logistics tracking and direct container loading for international shipping lines.
By integrating plantation, agricultural processing, bio-energy generation, and export logistics, Xinrui Group limits its exposure to raw material price spikes. Our Non-GMO crop contracts with local agricultural cooperatives ensure stable soybean and wheat prices, protecting our global partners from market volatility.
Our plants are strategically located with direct access to major rail networks and container ports. This allows us to offer flexible shipping terms (FOB, CIF, CFR) and guarantees fast turnaround times, even during high-demand shipping seasons.

Addressing the strict requirements of international feed mills, aquaculture integrators, and pet food brands.
For major aquafeed mills, Viscoelastic properties and water absorption indexes are critical specifications. Low-quality vital wheat gluten can fail to bind extruded pellets properly, leading to structural breakdown in water, high organic waste loads in ponds, and lower profitability.
Xinrui Group maintains a minimum crude protein content of 82% (dry basis) and wet gluten levels above 300% for all feed-grade vital wheat gluten exports. This guarantees excellent binding properties and digestibility in aquaculture environments.
For young animal nutrition, minimizing trypsin inhibitor activity and allergenicity is crucial. While standard soybean meals contain high levels of active antigens, our isolated soy proteins go through precise heat treatment and chemical isolation.
This process reduces trypsin inhibitors to less than 2.0 mg/g, ensuring optimal protein absorption and preventing intestinal issues in weaning pigs.
