Comparison between Holstein Cow’s Milk and Japanese-Saanen Goat’s Milk in Fatty Acid Composition, Lipid Digestibility and Protein Profile

Abstract

The fatty acid composition, the lipid digestibility and protein profile of Japanese-Saanen goat’s milk were characterized. Caprine milk contained substantial quantities of C_4:0 to C_10:0 fatty acids as compared with Holstein cow’s milk. The lipids of the former showed significantly higher digestibility in vitro by porcine lipase than those of the latter (P<0.05). As determined by SDS–PAGE, the respective contents of α_s1-casein, one of the major allergens, were 3.9% and 33.7% in caprine and bovine milk.
