ABSTRACT DESCRIPTION The present invention relates to methods selective extraction and / or prepurification of neighboring proteins and components (such as glycoproteins, pseudoproteins, conjugated proteins) contained in milk products in all forms, including including colostrum, using at least one precipitation stage. These processes are characterized in that they include at least one so-called precipitation step by adding at least one fatty acid of formula general CH3- (CH2) n-COOH in which n is a number integer at least equal to 4, and / or derivative and / or substituted acidic of said acid (s), said or said fatty acids and / or derivatives and / or substituted for acidic character being fluids at the temperature of treatment, and in quantity such as the initial report r between its or their mass in acid equivalent caprylic, and that of the proteins contained in the material to be treated initially and that we want precipitate is between 0.5 and 4.5, the pH being acid, the precipitation step being followed by step of separating the precipitate and the fraction liquid (Figure 1). |
