| Abstract: | The conditions of isolating and purifying casein glycomacropeptide （CGMP） were studied by ammonium sulfate precipitation and TCA. The results show that the purity of CGMP produced was 91.2% when 20% and 65% ammonium sulfate precipitation and 12% TCA were used. The entire processing conditions were simple, fast, low cost, so it was suitable for the industry. |
