Market Demand and Application Background of Soybean Concentrated Protein

In today's market, the demand for soybean concentrated protein (SPC) is on the rise. It is widely used in both the food and feed industries. In the food sector, SPC serves as a high - quality protein source, enhancing the nutritional value of products such as meat substitutes, dairy alternatives, and protein bars. In the feed industry, it provides essential amino acids for livestock and poultry, promoting healthy growth. The global market for SPC is expected to grow at a CAGR of around 5% in the next five years, according to market research.

Importance and Selection Criteria of Raw Materials

Penguin Group's SPC production technology starts with the careful selection of raw materials. Low - temperature defatted soybean meal and edible ethanol are the two key ingredients. Low - temperature defatted soybean meal ensures that the protein structure is not damaged during the production process. The ideal protein content of the low - temperature defatted soybean meal should be above 50%. When it comes to edible ethanol, its purity should be at least 95% to ensure efficient extraction of protein.

Removal of Anti - Nutritional Components

One of the critical steps in SPC production is the removal of anti - nutritional components, such as soybean sugars. Penguin Group uses a precise extraction and separation technology. Through this technology, the content of anti - nutritional components can be reduced to less than 1%. This not only improves the nutritional value of the product but also enhances its digestibility for both humans and animals.

Key Production Processes

Extrusion

Extrusion is a crucial step that affects the protein purity and functionality. During extrusion, the temperature and pressure are carefully controlled. The extrusion temperature is usually maintained between 120 - 150°C, which helps to denature the protein slightly and improve its solubility. This process can increase the protein solubility by about 10 - 15%.

Desolvation

Desolvation is used to remove the remaining ethanol from the product. The desolvation process is carried out under vacuum conditions to ensure that the ethanol content in the final product is less than 0.1%. This step is essential for the safety and quality of the SPC product.

Drying

Drying is performed to reduce the moisture content of the product. The moisture content of the final SPC product should be less than 8%. This helps to extend the shelf - life of the product and maintain its stability.

Ultrafine Grinding

Ultrafine grinding is the last step in the production process. It can make the particle size of the SPC product less than 100 microns, which improves its dispersibility and solubility in food and feed applications.

Equipment Production Capacity and Customization

Penguin Group's SPC soybean concentrated protein equipment has a diverse production capacity, ranging from 1 - 100 tons per day. This allows different enterprises, whether small - scale or large - scale, to choose the most suitable equipment according to their production needs. Moreover, the company also provides customized solutions to meet specific requirements of customers.

Future Development Trends

The future of SPC production technology is promising. There will be more research on improving the protein extraction efficiency and reducing the production cost. New technologies, such as enzyme - assisted extraction, may be introduced to further enhance the quality of SPC products.
