Abstract

Abstract: The separating conditions of bovine colostrums whey by hollow fiber ultra-filtration were confirmed on the basis of single factor tests as the result of ultra-filtrating temperature 25 ℃ and pressure 0.10 MPa. The purity of IgG extracted by caprylic acid-ammonium sulphate method is higher than that of IgG extracted by saturated ammonium sulphate solution method, reaching 85%. But saturated ammonium sulphate solution method is more feasible for industrial mass production.

Key words: bovine colostrums, ultra-filtration, salt out, immunoglobulin (IgG)
