Explore our top-tier industrial proteins designed to optimize feed efficiency, emulsion properties, and animal health metrics globally.
Analyzing the nutritional physics, environmental leverage, and efficiency mechanics of plant proteins in modern animal husbandry.
In modern animal husbandry, dietary efficiency is no longer simply about bulk weight gain; it is about metabolic conversion optimization, immune resilience, and clean formulation. Animal feed-grade vital wheat gluten and starch B derivatives present a powerful alternative to traditional synthetic additives or highly volatile fishmeal resources. With a highly stable amino acid index and unmatched digestibility coefficients, these plant-based extracts support the digestive systems of multiple species, from sensitive shrimp post-larvae to high-performance dairy cattle.
The global feed market is undergoing a structural transition driven by resource scarcity, supply chain disruptions, and dynamic ecological regulations. Traditionally, animal feed relied heavily on animal-derived proteins like fishmeal, or volatile legumes. Today, gluten meal—derived from the deep-processing of wheat—has established itself as an essential component in global nutrition matrix formulations. Its rich crude protein content (typically exceeding 75% to 82% dry basis) makes it an excellent concentrate for high-demand stages in aquaculture and early-weaned animal diets.
The quality of wheat gluten feed is decided in the extraction phase. At Guanxian Xinrui Industrial Co., Ltd., we have replaced obsolete processing routes with the world's most advanced Tri-canter Separation Technology. This fully closed, hygienic production loop minimizes chemical manipulation, relying instead on high-speed mechanical centrifugal force to separate raw wheat flour slurry into its constituent parts: vital wheat gluten, high-purity Starch A, and secondary Starch B.
1. Milling and Slurry Hydration: Select domestic wheat is milled to precise flour specifications and hydrated to develop a stable gluten network.
2. Centrifugal Fractionation: The slurry is fed into high-speed three-phase decanters. Vital wheat gluten (wet elastic mass) is separated immediately, while the starch fractions divide into heavy Starch A (large granules) and light Starch B (pentosans and smaller starch granules).
3. Flash Drying and Pelleting: The gluten is dry-flashed in fraction-of-a-second cycles to retain its native viscoelastic properties. Concurrently, Starch B and pentosans are channeled directly into our integrated ethanol and feed manufacturing units, ensuring 100% biomass utilization.
Looking forward, our technical roadmap focuses on enzymatic hydrolysis optimization. By breaking down native gluten into bioactive low-molecular-weight peptides, we aim to design next-generation animal feeds with functional immunomodulatory benefits. These advanced peptides act directly on gut microflora, boosting systemic immunity and minimizing dependency on pharmaceutical supplements in global livestock farming.
Based in Shandong, China, the Xinrui Group leverages a vertically integrated circular economy model to protect global buyers against supply volatility. Operating since 2003 and spanning over 1,000 mu, our group achieves massive economies of scale by integrating electricity generation, steam supply, agricultural planting, deep-processing, and international trade under a single organizational framework.
Through Guanxian Ruichang Trading Co., Ltd. (established in 2011 with a registered capital of 6 million Yuan), the group exports vital wheat gluten, isolated soy protein, soluble dietary fiber, and superior grade ethanol directly to international customers. By managing the logistics directly from the manufacturing line to the shipping port, we eliminate intermediate handling fees and ensure complete control over transit conditions. Over 70% of our group's total production capacity is exported, serving major agricultural hubs across Asia, Europe, the Americas, and the Middle East.
The applications for our feed-grade products span a variety of specialized markets, each requiring unique functional characteristics:
Operating a global agricultural supply chain demands strict adherence to local and international food safety and biosecurity regulations. Every batch of gluten meal and starch produced at our plants undergoes rigorous quality control testing in our internal laboratories and is verified by independent third-party testing agencies such as SGS.
We maintain a comprehensive certification portfolio to simplify import clearance for our clients: HACCP, ISO9001, ISO22000, BRC, HALAL, KOSHER, and IP-NON GMO. These certifications guarantee that our materials are fully traceable from our wheat and non-GMO soybean planting bases directly to the final shipped cargo container.
Additionally, Shandong Kawah Oils Co., Ltd., a key subsidiary established in 2014, processes 180,000 tons of domestic non-GMO soybeans annually to extract premium food-grade soybean oil, low-temperature soy meal, isolated soy protein, and soy dietary fiber. Our single spray-drying tower line, designed by DACHUANYUAN, is the largest single production line in China, ensuring consistent quality and volume for customers requiring large-scale botanical protein supplies.

• Guanxian Ruichang Trading Co., Ltd.: The group's dedicated direct export entity, handling international shipping and documentation directly from our factories.
We have obtained a comprehensive set of international certifications to ensure compliance with strict regional regulations: HACCP, ISO9001, ISO22000, BRC, HALAL, KOSHER, IP-NON GMO, and SGS. Additional certifications can be arranged upon request to meet local market entry barriers.
Our feed-grade vital wheat gluten features a minimum crude protein content of 75% to 82% (on a dry basis), with a high digestibility rate exceeding 90%. This makes it a popular choice for aquaculture feed, piglet creep feed, and premium pet food formulations.
This process uses high-speed mechanical centrifugation instead of chemicals to separate protein from starch. This preserves the protein's native structure and functional properties, resulting in a cleaner product with zero chemical residues.
Xinrui Group operates its own cogeneration plant, supplying consistent steam and thermal energy to our spray drying and milling lines. This insulates our operations from external power grid disruptions and volatile energy prices, offering buyers long-term price stability.
We offer flexible packaging configurations including 25kg multi-wall paper bags, 50kg woven bags, and 1,000kg bulk jumbo bags (FIBCs), adapted to different storage and automated conveying systems.
Wheat gluten offers stronger binding properties (excellent for aquafeed pellets) and has significantly lower levels of anti-nutritional factors (ANFs) compared to standard soy meal. This makes it gentler on the digestive systems of juvenile animals, such as early-weaning piglets.
