This study investigated on the protein fractions characterization of sheep milk obtained by Comisana breed. Milk samples collected by 94 sheep were subjected to RP-HPLC analysis, in order to determine caseins and seroproteins contents. A total seroproteins content of 17.0 g/l was determined, while the total casein content was 39.0 g/l. The seroproteins content was further investigated by RP-HPLC, determining an α-lactalbumin content of 1.6 g/l, higher if compared to dairy cow’s milk, and two variants of β-lactoglobulin, with a content respectively of 16.7 g/l and 11.0 g/l. Since the RP-HPLC did not permit an accurate separation of the different variants of caseins, other studies are currently in progress using a proteomic approach.

Abstract

This study investigated on the protein fractions characterization of sheep milk obtained by Comisana breed. Milk samples collected by 94 sheep were subjected to RP-HPLC analysis, in order to determine caseins and seroproteins contents. A total seroproteins content of 17.0 g/l was determined, while the total casein content was 39.0 g/l. The seroproteins content was further investigated by RP-HPLC, determining an α-lactalbumin content of 1.6 g/l, higher if compared to dairy cow’s milk, and two variants of β-lactoglobulin, with a content respectively of 16.7 g/l and 11.0 g/l. Since the RP-HPLC did not permit an accurate separation of the different variants of caseins, other studies are currently in progress using a proteomic approach.
