Industrial grade isolated soy proteins and functional fibers for optimal texture, stability, and nutritional delivery in bar manufacturing.
The global protein bar market has transitioned from a niche bodybuilding supplement to a mainstream, daily nutritional solution for active consumers, professionals, and health-conscious demographics. Today, brands must meet multi-layered demands: high protein delivery, low glycemic index, clean label requirements, vegan suitability, and exceptional texture that prevents the product from turning hard over its shelf life.
Raw ingredient quality is the single most critical factor in determining a protein bar’s success. The selection of Isolated Soy Protein (ISP) and wheat gluten dictates the water-binding capacity, extrusion efficiency, mouthfeel, and protein digestion parameters. Global brands are increasingly pivoting towards plant-based protein foundations that offer reliable organoleptic characteristics, cost stability, and supply chain predictability.
Information Gain: Industrial-scale protein bar extrusion requires proteins with controlled denaturation indices to ensure bars maintain soft textures for 12+ months. Our tailored ISP 9030 & 9003B grades are specifically optimized to inhibit moisture migration and retrogradation.
Analyzing key pain points faced by procurement officers, food chemists, and contract manufacturers globally.
Consumers demand verified ingredients. Sourcing certified IP Non-GMO raw materials with full genetic trace records from crop to container is paramount to regulatory compliance in the EU and NA markets.
Processing plant-based protein bars on high-speed industrial lines demands exact powder densities and particle size distribution. Poor solubility leads to grid blockages; high viscosity disrupts bar shape integrity.
Overcoming the natural beany notes of soy isolates without chemical masking agents is a core R&D challenge. High-emulsion type proteins like Kawah Oils' ISP series offer a clean taste panel profile.
Established in May 2003, Xinrui Group has developed into a highly diversified industrial group covering more than 1,000 mu, achieving an annual output value of 2.8 billion Yuan. We operate specialized subsidiaries, including cogeneration, urban heating, and gas supply systems, which fuel our massive agricultural processing facilities.
Our core asset, Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd), established in 2007 with a registered capital of 100 million Yuan, processes 500,000 tons of wheat flour annually. Using state-of-the-art imported tri-canter separation technology, we produce high-grade vital wheat gluten, wheat starch A, and wheat starch B. To fulfill our commitment to a zero-waste circular economy, starch B and pentosans are dynamically routed into the production of high-purity industrial ethanol and animal feed.

Established in 2014 with 120 million Yuan in registered capital, Shandong Kawah Oils Co., Ltd. stands as a provincial leading agricultural industrialization enterprise. The company integrates crop plantation, scientific research & development, deep manufacturing processes, and import/export operations.
Processing 180,000 tons of domestic plant-sourced NON-GMO soybeans annually, Kawah Oils utilizes advanced sequential extraction lines. We step-by-step produce premium non-GMO soybean oil, low-temperature food-grade soybean meal, isolated soy protein, and soy dietary fiber.
Our core production asset is the industry-leading DACHUANYUAN spray drying tower. With a single production line capacity unmatched in China, it represents the pinnacle of modern powder engineering, guaranteeing uniform particle shape, exceptional dispersion properties, and zero contamination risks.
Combining mechanical automation, automated closed-loop production, and clean-in-place (CIP) protocols to ensure uninterrupted B2B product supply.
We minimize biological contact and airborne contaminants by implementing closed, automated packing terminals right after the DACHUANYUAN spray dryer, guaranteeing pristine hygiene standards before export.
By leveraging Xinrui Group’s dedicated municipal heating and gas cogeneration utilities, our factories operate under a highly stable energy cost structure, buffering global clients from sudden energy price spikes.
Situated in Shandong, the heart of agricultural logistics in China, we manage integrated transportation lanes. Via Guanxian Ruichang Trading Co., Ltd. (founded in 2011, capital of 6M Yuan), we export over 70% of our capacity directly to overseas destinations.
Different markets dictate specific physical and nutritional traits. Here is how our raw materials address global formulation standards.
Targeting clean labels, low-net-carb profiles, and high protein targets. Sourcing requires functional non-GMO soy protein concentrates with exceptional binding capability to accommodate sugar alcohols and keto-friendly lipid matrices without fat separation.
Strong emphasis on non-GMO identity preservation (IP certificates) and compliance with clean manufacturing frameworks. Products require high-dispersion proteins (like ISP 9030) to facilitate soft cold-extrusion without chemical texturizers.
Snackification of protein bars targeting lighter portion sizes, green-tea/matcha flavors, and dietary fiber supplementation. Utilizing Soy Dietary Fiber in combination with isolated soy proteins provides crispness, reduces caloric density, and satisfies digestive wellness positioning.
Our raw materials pass rigorous international audits to ensure seamless customs entry and absolute safety compliance.

We are a fully integrated group company named Xinrui Group, consolidating manufacturing assets and exporting pathways. The production of isolated soy protein is handled by Shandong Kawah Oils Co., Ltd (annual capacity of 50,000 tons). The wheat gluten is processed by Guanxian Xinrui Industrial Co., Ltd. (formerly Guanxian Ruixiang Biotechnology Development Co., Ltd), producing 30,000 tons of vital wheat gluten per year. All direct exports are managed under our integrated trading division, Guanxian Ruichang Trading Co., Ltd.
We hold HACCP, ISO9001, ISO22000, BRC, HALAL, KOSHER, and IP-NON GMO certifications. Additional testing reports and target audits can be facilitated upon request.
Different protein grades perform differently in bars. High gelling types (like ISP 9500) provide structure, whereas dispersion-optimized types (like ISP 9030) prevent moisture absorption from the sugar syrup matrix, preventing protein bars from hardening over time. Food scientists typically blend these proteins with soy dietary fibers to achieve the perfect balance between soft extrusion and structural stability.
Through Ruichang Trading, we export over 70% of our production volume. With close proximity to major ports and fully automated logistics packing, we regularly secure large-scale contracts with flexible scheduling and reliable delivery windows.
