Abstract

The fatty acid composition and cholesterol content of 22 camel’s milk samples from different regions of Kazakhstan were determined, in different seasons and with different camel species (Bactrian, dromedary and hybrids). Camel milk fat differed from mammalian fats by its high content of the long-chain fatty acids C14:0, C16:0, C18:0 and C18:l. Great differences in fatty acid composition occurred between regions. Short-chain fatty acids (C8:0 and C10:0) were in higher proportion in spring and long-chain fatty acids (C17:0 and C17:1) in autumn. Dromedary milk had a higher proportion of C17:0iso and C18:1 than Bactrian milk. The ratio of unsaturated/saturated acid was more favorable in camel’s milk compared with that of cows or other mammalians. All of these parameters gave a nutritional advantage to camel’s milk, although it had a higher content of cholesterol (37.1 mg·100 g−1) than cow’s milk. Multivariate analysis allowed the identification of four types of fatty acid profiles with a clear opposition between the samples rich in short-chain fatty acids and the samples rich in long-chain fatty acids. These results confirmed that environmental and farming conditions allowed modulation of the lipid composition of camel’s milk.

Abstract

22 (C14:0 C16:0 C18:0 C18:1) (C8:0 C10:0) (C17:0 C17:1) iso-C17:0 C18:1 (37.1 mg·100 g−1)

Résumé

La composition en acides gras et la teneur en cholestérol ont été déterminées dans 22 échantillons de lait de chamelle du Kazakhstan, provenant de différentes régions, à différentes saisons et de différentes espèces (chameau de Bactriane, dromadaire et hybrides). La matière grasse du lait de chamelle comprend comme acides majeurs C14:0, C16:0, C18:0 et C18:1. Les acides gras à chaînes courtes (C8:0, C10:0) sont en proportion plus élevée au printemps et ceux à chaînes longues (C17:0, C17:1) en automne. Le lait de dromadaire a surtout une plus forte proportion en C17:0iso et C18:1 que le lait de Bactriane. Le rapport acides insaturés/acides saturés est en faveur du lait de chamelle comparé au lait de vache. Cette composition donne un avantage nutritionnel au lait de chamelle, mais sa teneur en cholestérol (37,1 mg·100 g−1) est plus élevée que dans le lait de vache. L’analyse multivariée a permis d’identifier quatre types de profils d’acides gras avec une claire opposition entre des laits riches en acides à courtes chaînes et des laits riches en acides à longues chaînes. Ces résultats confirment que l’environnement et les conditions d’élevage permettent de moduler la composition des lipides du lait de chamelle.
