Membrane separation technology refers to a process that uses selective barriers (membranes) to separate components from a mixture based on their size, charge, or other properties. This technology is widely used in various industries, including water treatment, food processing, and pharmaceuticals. The main types of membrane separation processes include: 1. **Microfiltration (MF)**: Removes larger particles, such as bacteria and suspended solids, typically with pore sizes ranging from 0.1 to 10 micrometers. 2. **Ultrafiltration (UF)**: Separates smaller particles, including proteins and colloids, with pore sizes between 1 nanometer and 0.1 micrometers. 3. **Nanofiltration (NF)**: Targets divalent ions and small organic molecules, with pore sizes around 0.001 to 0.01 micrometers. 4. **Reverse Osmosis (RO)**: Removes almost all dissolved salts and small molecules, with pore sizes less than 0.001 micrometers. Membrane separation is advantageous due to its energy efficiency, low chemical usage, and ability to operate at ambient temperatures. However, challenges such as membrane fouling and limited lifespan must be managed to ensure optimal performance.

Innovatively applying membrane separation technology in the processing of colostrum products: The sterilization process uses membrane microfiltration technology, which completely reduces microbial levels through physical retention and removes microbial bodies, making the product safer. The process controls the temperature below 20°C, fully ensuring the biological activity of functional substances such as immunoglobulins. The concentration process uses membrane ultrafiltration concentration technology, which also utilizes physical filtration methods to concentrate colostrum while maintaining low temperatures throughout the process. This allows for the removal of some lactose and inorganic salts, making the final product suitable for a wider range of consumers, such as those who are lactose intolerant, and reducing the renal burden caused by high salt. The colostrum powder produced by this process has high immunoglobulin content, good solubility, and excellent taste.
