A method of extracting a target product from a milk raw material
By combining ultrafiltration and conductivity-adjusted pretreatment with strong and weak anion exchange chromatography, the problem of low extraction efficiency of multiple components from milk raw materials in existing technologies has been solved. This method achieves efficient and high-purity extraction of β-lactoglobulin, α-lactalbumin, casein micelles, lactose, and milk mineral salts, thereby improving the added value and resource utilization efficiency of milk by-products.

AI Technical Summary
Existing technologies struggle to efficiently and effectively extract β-lactoglobulin, α-lactalbumin, casein micelles, lactose, and milk mineral salts from dairy raw materials, resulting in problems such as high equipment investment, high energy consumption, low purity, and structural damage.
A method combining ultrafiltration and conductivity-adjusted pretreatment with strong and weak anion exchange chromatography was adopted. Impurities were removed by ultrafiltration, chromatographic conditions were optimized by precise conductivity adjustment, and membrane filtration technology was combined to achieve efficient extraction of multiple components.
It significantly improved the speed and efficiency of chromatography, enhanced the purity and stability of the target products, and achieved high-purity extraction of β-lactoglobulin and α-lactalbumin, thereby increasing the added value and resource utilization efficiency of dairy by-products.
