Barcelona and the wider Catalonia region stand as the vibrant heartbeat of Southern Europe's plant-based transition and advanced food processing industry. Backed by world-class food tech hubs and progressive culinary institutes, Barcelona's food manufacturers demand protein ingredients of exceptional functional profile and strict regulatory certification. Shandong Kawah Oils Co., Ltd, under the umbrella of the renowned Xinrui Group, meets this demand head-on by exporting superior-grade, non-GMO Isolated Soy Protein engineered for high emulsification, water binding, and gelling properties.
Operating as our global direct trade integration vehicle, Guanxian Ruichang Trading Co., Ltd manages seamless container logistics from our industrial refining complex directly to the Port of Barcelona. This bypasses intermediary costs and delivers massive economies of scale to Catalonian processors, meat manufacturing specialists (such as traditional charcuterie operations looking to transition to hybrid formulations), and advanced functional beverage brands.
Specially curated isolated soy protein formulations optimized for Spanish charcuterie, vegan alternatives, and nutritional formulations.
Catalonia represents one of the largest food manufacturing sectors in Europe, accounting for nearly 24% of Spain’s total food industry turnover. Within this framework, Barcelona is historically anchored as a major center for pork processing, charcuterie manufacturing, and modern meat packing. Landmark regional specialties, ranging from cured Spanish sausage (Fuet and Salchichón) to emulsified boiled hams and mortadella products, rely heavily on clean-label additives that can successfully mimic texture, stabilize fat-water matrices, and reduce formulation costs.
As the European Union moves aggressively toward sustainability goals and consumers opt for meat reduction, Barcelona has evolved into a global hotbed for meat alternative startups and hybrid protein formulations. In Catalonia, plant-based startups, corporate R&D divisions, and industrial pilot plants are working closely to design products with high organoleptic score ratings. Our Isolated Soy Proteins (ISP) act as the functional backbone in these developments. The extremely high protein concentration (≥90% on dry basis) allows processors to bind fat and water structurally, which mimics the sensory chewiness of myofibrillar animal proteins while retaining a highly desirable clean taste profile.
Understanding the molecular properties of soy globulins (specifically the 7S β-conglycinin and 11S glycinin ratios) is crucial for precision product formulation. Our advanced manufacturing facility, Shandong Kawah Oils Co., Ltd, implements state-of-the-art pH shift extraction technology and sophisticated spray-drying parameters to alter the tertiary structure of proteins. This ensures excellent dispersion, fast hydration, and robust gel matrix formations under heat processing.
Non-GMO low-temperature desolventized soybean flakes undergo mild alkaline extraction (pH 7.2–8.0) to maximize the solubility of high molecular weight 7S and 11S globulins, preserving their native configurations.
Acidification to the isoelectric point isolates the soy protein fraction from soluble sugars and fibers. This ensures an ultra-clean taste profile, removing off-flavors and oligosaccharides that cause digestive discomfort.
Precise sodium/potassium hydroxide neutralization returns the protein slurry to pH 6.8–7.2. High-temperature short-time (HTST) sterilization removes microbial loads while maintaining protein functional integrity.
Our single-line capacity DACHUANYUAN spray drying towers control atomization and heat profiles. This controls particle size distribution, density, and solubility indices, generating instantly soluble powder particles.
By optimizing these production steps, we achieve precise control over the Water Holding Capacity (WHC) and Oil Holding Capacity (OHC), vital parameters for food safety, quality, and cost management in the plant-based and meat industries of Spain.
Solving texture, viscosity, and emulsification challenges across diverse food categories.
Specifically developed for hot dogs, mortadella, frankfurters, and canned luncheon meats. Promotes a strong 1:5:5 water-fat-protein binding structure that prevents fat separation under retort sterilization.
Our low-viscosity, high-dispersion soy protein isolates (such as the 9020/9026 series) allow seamless passage through injector needles without clogging, enhancing sliceability and water retention in premium hams.
Specially engineered dispersion-grade soy protein isolates (9030/9032) demonstrate high solubility, low dusting, and zero grit texture. Ideal for acidic sport drinks, protein bars, and infant formula bases.
Established in May 2003, the XINRUI GROUP covers a total area of more than 1,000 mu. Driven by industrial modernization and local community support, the group operates a highly efficient circular economy industrial chain. This complex integrates wheat deep processing (processing 500,000 tons of wheat flour per year into gluten, starch, pentosan, alcohol, and animal feed) alongside our specialized soybean processing operations. With a cumulative annual output valuation exceeding 2.8 billion Yuan, we possess the raw material control and financial stability to secure massive supply agreements for our European partners.
Our primary facility for Isolated Soy Protein, SHANDONG KAWAH OILS CO., LTD (established in 2014 with a registered capital of 120 million Yuan), functions as a provincial leading agricultural industrialization enterprise. Processing 180,000 tons of local non-GMO soybeans annually, the facility produces high-grade oil, low-temperature soy meal, protein isolates, and soy dietary fibers. Our focus on modern spray drying tower tech makes this the largest single isolated soy protein production line in China, ensuring maximum chemical and functional stability.
Our production facilities maintain the most stringent Quality Management Systems (QMS) to comply with Spanish food regulations and EFSA directives.
