Order direct testing samples to inspect structural characteristics, dispersibility, and emulsification performance across targeted food manufacturing matrices.
A deep analysis of chemical metrics, rheology profiles, and supply chain verification in enterprise plant-protein acquisition.
In high-throughput food manufacturing, plant protein is more than a nutritional additive; it is a structural cornerstone. Food engineers, research scientists, and procurement managers know that raw specification sheets do not fully capture behavior under sheer stress, high heat, and variable pH conditions. Requesting a physical evaluation sample allows organizations to evaluate structural functional behaviors beforehand.
Whether you are formulating emulsified meat products, plant-based cheese, high-protein beverages, or nutritional supplements, testing is key. The water binding capacity (WBC), gelation kinetics, and viscosity profile must align with your processing equipment. Evaluating physical samples prevents downstream batch losses and line downtime.
"Providing free protein powder samples enables collaborative testing between the factory and formulation laboratories, matching precise protein particle structures to operational requirements."
At Xinrui Group, we support this trial stage. Through our direct trading arm, Guanxian Ruichang Trading Co., Ltd, we deliver industrial-grade samples of Isolated Soy Protein, Vital Wheat Gluten, and Soy Dietary Fiber to verification labs globally.
Perform these quality checks on your free protein powder samples:
Our integrated plants run 24/7, processing 500,000 tons of wheat flour and 180,000 tons of soybeans annually, with over 70% of production exported globally.
We raw-source exclusively from identity-preserved, Non-GMO soybean fields in Northern China, managing the supply chain from planting to final protein isolation.
We operate China's largest single-line spray drying tower, manufactured by DACHUANYUAN, alongside imported European tri-canter separation equipment.
Fully certified under HACCP, ISO9001, ISO22000, BRC, HALAL, KOSHER, and SGS standards to meet the compliance audits of international food companies.
How shifting dietary patterns and international trade require high-efficiency industrial processing networks.
The demand for plant-based proteins is accelerating across both developed and emerging markets. Sourcing strategies are moving away from simple pricing models toward long-term agreements with vertically integrated processors. In North America and Europe, clean-label plant protein isolates are widely used in functional foods, sports nutrition, and meat-alternative formulations. Meanwhile, in developing markets, isolated soy protein is essential for maintaining moisture and texture in emulsified meat products, bakery lines, and dairy alternatives.
This dynamic has elevated the importance of offering free protein samples. Enterprise buyers require access to raw materials to test viscosity, dispersion, and emulsification performance. Testing raw materials under factory floor conditions helps brands maintain consistency and secure supply chains.
Matching specific protein grades to target food matrices and industrial production lines.
Our meat and emulsion-type proteins (9001BW/9001B-Y/9000 and 9007B-A/C) are designed to form strong heat-stable emulsions, holding water and fat in structured meat matrices like sausages and meatballs.
Our beverage-type proteins (9030/9032) are optimized for high solubility and dispersion, preventing sedimentation in ready-to-drink (RTD) beverages and dry mix formulations.
Vegetarian-grade proteins like 9005B and 9003B are developed to form strong protein networks under calcium or magnesium salt coagulation, essential for traditional tofu and meat analogues.
Inside our advanced production facilities: Sourcing low-temperature soybean meal and utilizing tri-canter separation.
The Xinrui Group operates an integrated circular processing model. At our wheat processing plant (processing 500,000 tons of wheat flour annually), we extract wheat gluten and wheat starch (A and B grades) using modern tri-canter separation equipment. The starch B and pentosan side streams are recycled directly into ethanol and animal feed production.
Similarly, Shandong Kawah Oils Co., Ltd sources local Non-GMO soybeans to extract soy oil, low-temperature meal, isolated soy protein, and dietary fiber. Every by-product is redirected back into the manufacturing cycle, supported by our cogeneration plant that provides steam, heat, and electricity to our operations.
A key asset in our soy protein isolate production is the DACHUANYUAN spray drying system installed at Kawah Oils. As China's largest single-line spray drying tower, it controls the heat exposure of the slurry, protecting the functional properties of the soy globulin proteins. This precise control over particle size distribution ensures fast dispersion in water, helping formulators achieve consistent results when testing our samples.

Technical answers regarding sample shipments, testing standards, and our circular production lines.
We are an integrated group company named Xinrui Group that handles both manufacturing and export operations. The soy protein isolate is manufactured by our subsidiary, Shandong Kawah Oils Co., Ltd, which has a production capacity of 50,000 tons of isolated soy protein per year. The vital wheat gluten is manufactured by Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd), producing 30,000 tons of wheat gluten annually. All international shipping, documentation, and customer service are managed by our direct export trading arm, Guanxian Ruichang Trading Co., Ltd. (established in 2011 with 6 million yuan of registered capital).
Our facilities are certified under HACCP, ISO9001, ISO22000, BRC, HALAL, KOSHER, IP-NON GMO, and SGS. We can provide copies of these certificates alongside sample shipments for compliance reviews.
Verified food manufacturers, R&D labs, and wholesale buyers can request free evaluation samples (typically 200g to 1kg) through our trading arm, Guanxian Ruichang Trading Co., Ltd. We ask that buyers provide details about their application requirements so we can recommend the appropriate grade (e.g., high-emulsification, injection, low-viscosity beverage, or tofu-coagulating type).
We operate an identity-preserved (IP) Non-GMO supply chain. Our raw materials are sourced from controlled planting bases in Northern China. Each step—from seed selection and planting to harvesting, transportation, and low-temperature oil extraction—is documented and audited to ensure zero cross-contamination.
Our integrated facility handles wheat milling, soy crushing, starch extraction, cogeneration, and ethanol distillation in one location. This circular process allows us to recycle by-products like starch B and pentosan into animal feed and alcohol production. This integration reduces waste and operating costs, helping us maintain stable pricing for our global partners.
