Abstract

This study comparatively investigated the seasonal differences between winter and spring on fatty acid composition of mutton from Erdenedalai soum in Dundgovi Province, Mongolia. The results showed that oleic acid (C18:1 n-9) was the predominant fatty acid in all samples, accounting for 34.66%–43.57% of total fatty acids. Compared with winter samples, higher contents of palmitic acid (C16:0) and oleic acid were observed in spring samples, whereas butyric acid (C4:0) was markedly higher in winter samples. The lipid health indices indicated that the PUFA/SFA ratio ranged from 1.03 to 1.39, the n-6/n-3 ratio ranged from 1.33 to 1.89, and both the atherogenic index (AI) and thrombogenic index (TI) were at low to moderate levels. Overall, Mongolian mutton exhibited noticeable seasonal variation in fatty acid composition, and its lipid structure demonstrated a relatively balanced nutritional profile.
