Tailored high-solubility, gelling, and emulsifying isolated soy proteins specifically optimized for European Union regulatory standards and Spanish culinary texture profiles.
The Spanish food processing sector is undergoing a profound paradigm shift. Historically celebrated for its traditional cured meats, dry-cured sausages (such as Chorizo, Salchichón, and Fuet), and cooked ham lines, Spanish manufacturers are actively incorporating advanced functional plant proteins to optimize formulation yields, enhance emulsion stability, and satisfy the growing flexitarian consumer base.
With the rapid rise of plant-based culinary alternatives across major hubs like Barcelona, Madrid, and Valencia, isolated soy protein (ISP) has transitioned from a basic functional additive to a cornerstone ingredient. High-purity isolated soy protein (containing ≥ 90% dry-basis protein) acts as a highly efficient gelling agent, fat emulsifier, and water binder. The integration of ISP enables food companies in Spain to significantly lower manufacturing costs while improving the sensory profiles and nutritional footprints of their end products.
Furthermore, EU regulations regarding GMO traceability and deforestation-free supply chains (EUDR) dictate that soy protein sourcing must satisfy stringent, non-negotiable standards. As a premier manufacturer, our IP-Non-GMO certification represents a crucial competitive advantage for Spanish distributors seeking safe, clean-label, and reliable ingredients.
The global market for isolated soy protein is expected to continue its robust expansion trajectory, driven by clean-label food engineering and high-protein sports nutrition trends. As agricultural inputs face climate uncertainty, building a resilient supply partnership is essential for European purchasers. The modern food industry demands vertical integration. Our parent group, Xinrui Group, established in May 2003, commands massive scale with a deep-processing circular economy model that converts agricultural inputs into high-value functional proteins.
Operating through our specialized subsidiaries, Shandong Kawah Oils Co., Ltd and Guanxian Xinrui Industrial Co., Ltd, we process 180,000 tons of soybeans and 500,000 tons of wheat flour annually. Our raw materials are harvested from our own dedicated, rigorously monitored Non-GMO planting bases. By controlling every variable from seed sowing to chemical extraction, we buffer our Spanish partners against global raw material volatility and assure compliance with EU import regulations.
Our emulsion-type soy proteins (9001BW, 9007B-A) stabilize Spanish processed meats, locking in moisture and fats during thermal processing. They guarantee zero separation in frankfurters and vacuum-packed salchichón.
Designed for cooked hams (Jamón Cocido), our high-dispersibility injection-type proteins (9020/9026/9028) dissolve quickly in cold brine without clogging injection needles. They improve sliceability and texture.
For tofu, vegan tapas, and plant-based burgers, our specialized vegetarian soy proteins (9003B, 9005B) offer a fibrous protein matrix that mimics animal muscle fibers, providing excellent bite and chewiness.
How do we manufacture isolated soy protein with such high protein concentrations and functional adaptability? Our factory employs an advanced low-temperature extraction process paired with state-of-the-art spray drying technology. By executing the extraction inside clean, closed-loop facilities using tri-canter separation technology, we prevent protein denaturation and preserve the native gelling and emulsifying capacity of the soybean globulins.
The core of our processing line features a single-line spray drying tower imported from DACHUANYUAN. Boasting one of the largest single-line spray-drying capacities in China, this setup ensures unmatched physical uniformity, exceptional particle size distribution, and outstanding dissolution characteristics.

We are a fully integrated group company named Xinrui Group. The manufacturer of our isolated soy protein is Shandong Kawah Oils Co., Ltd, which produces 50,000 tons of isolated soy protein per year. Our wheat gluten is manufactured by Guanxian Xinrui Industrial Co., Ltd, which produces 30,000 tons of vital wheat gluten per year. All direct exporting operations are managed by our trading arm, Guanxian Ruichang Trading Co., Ltd, which simplifies customs and shipping paperwork to main Spanish ports such as Valencia, Barcelona, Bilbao, and Algeciras.
We hold IP-Non GMO (Identity Preserved), HACCP, ISO9001, ISO22000, BRC, HALAL, KOSHER, and SGS certificates. These certificates guarantee that all soybeans are strictly IP-Non-GMO from farm to processing, avoiding any cross-contamination. This ensures full compliance with EFSA requirements and Spanish local health and labeling laws.
Our emulsion-type isolated soy protein offers an excellent 1:5:5 emulsification ratio (1 part protein, 5 parts water, 5 parts lipids). This matches or exceeds the emulsifying power of sodium caseinate or plasma proteins under pasteurization conditions, providing Spanish meat manufacturers with an effective strategy to lower formulation costs without losing structure.
From confirmation and packaging alignment, production typically takes 7-10 days, followed by 3-5 days of rail/road transit to China's main ports (Qingdao/Tianjin). Ocean shipping from Qingdao to Spanish ports like Barcelona or Valencia takes approximately 30-35 days, bringing the total estimated lead time to around 40-45 days.
