1:10 diluted whole raw milk were offered to pure HA and HA
microbeads as described in Section 2.6. All of the proteins, except of casein, were adsorbed on pure HA (Fig. 7A) with none selectivity. Whereas only α-LA (the small proteins are α-lactalbumin and β-lactoglobulin
in milk) adsorbed on HA microbeads (Fig. 7B) and there was a preferential adsorption of α-LA compared with other milk proteins, the band ofα -LA disappeared after adsorption (Fig. 7B)
