Highly functional isolated soy protein models specifically calibrated for local sausage processors, traditional Bulgarian Lukanka charcuterie, and emulsion stabilization.
As an active member of the European Union, Bulgaria's food manufacturing industry has undergone a radical transformation. Traditional meat production facilities—ranging from regional producers of historical dried sausages (like *Lukanka*, *Sujuk*, and *Karnache*) to modern industrial poultry and pork processing centers in Sofia, Plovdiv, and Varna—increasingly require high-performance, cost-effective binding and emulsification solutions.
At the same time, the Balkan region is experiencing an unprecedented surge in plant-based and vegan alternatives. Today's consumer trends show a rising demand for clean-label, dairy-free spreads, and meat replacements. This requires a stable supply of Non-GMO Isolated Soy Protein that delivers high gel strength, exceptional water absorption, and superior fat emulsion qualities.
Our advanced production facilities, operating under rigorous international food standards, serve as the vital link. By supplying premium soy isolates, we help Bulgarian food technologists optimize recipe costs while elevating nutritional profiles, satisfying both local regulatory guidelines and discerning modern consumers.
Strict adherence to European GMO regulations (EC No 1829/2003). Every batch supplied to the Bulgarian market is certified non-GMO, tracing directly back to localized contracted crop fields.
Specifically engineered to maintain emulsion stability through intense thermal processes, ensuring minimal water and fat separation in retail packaging.
Why leading global and regional European manufacturers prioritize our integrated circular supply chain.
Our 9000 & 9007 series features a customized molecular structure that absorbs water and fat in a 1:5:5 ratio, guaranteeing excellent sliceability and texture preservation under refrigerated transport across Bulgaria.
For cured meats and whole muscle products, our injection type proteins (9020/9026/9028) dissolve rapidly at low temperatures without clogging needles, maintaining high dispersal rate and high yields.
Designed to eliminate the typical "beany" flavor note through specialized wash and drying technologies, providing an optimal neutral base for vegan yogurts, protein drinks, and plant-based sausages.
Unveiling our vertically integrated circular economy model that guarantees quality from planting to delivery.
GUANXIAN XINRUI INDUSTRIAL CO., LTD. (formerly known as GUANXIAN RUIXIANG BIOTECHNOLOGY DEVELOPMENT CO., LTD) was established in 2007 with registered funds of 100 million Yuan. The company processes 500,000 tons of wheat flour per year. Using premium wheat materials, we produce vital wheat gluten, wheat starch A, and wheat starch B. The downstream byproducts like starch B and pentosan are recycled for alcohol and animal feed production. This deep-processing circular economy industry chain maximizes raw material efficiency and lowers overall environmental impact.
We imported the most advanced tri-canter separation technology for wheat gluten production, ensuring a completely clean, closed, and modern facility. Output value, equipment sophistication, and quality standards sit at the absolute forefront of national counterpart metrics.
Our dedicated trading arm, GUANXIAN RUICHANG TRADING CO., LTD., founded in 2011 with 6 million Yuan registered capital, directly exports isolated soy protein, wheat gluten, soluble dietary fiber, vermicelli, and ethanol to overseas customers. The export volume represents over 70% of the group company's production capacity, bridging the gap between factory floor and global buyers.
Established in 2014 with 120 million Yuan registered capital, SHANDONG KAWAH OILS CO., LTD. is a leading provincial agricultural industrialization enterprise. Kawah Oils integrates raw material planting, research and development, deep processing, and export functions.
Processing 180,000 tons of domestic Non-GMO soybeans annually, the facility systematically extracts premium non-GMO soybean oil, low-temperature food grade soybean meal, isolated soy protein, and dietary fiber.
Our advanced isolated soy protein production features the state-of-the-art DACHUANYUAN spray drying tower. With a single-line capacity that leads domestic scales, it represents the largest single production line in China, ensuring massive batch consistency and uninterrupted logistics for high-volume contracts.
Documented proof of premium quality standards, rigorous safety testing, and automated industrial plants.
To ensure zero friction at the Bulgarian customs borders, our isolated soy proteins are backed by comprehensive certification documents. We continuously maintain qualifications required by top-tier global food brands:
Xinrui Certificate 1
Xinrui Certificate 2
Xinrui Certificate 3
Xinrui Certificate 4
Xinrui Certificate 5
