Abstract:
This research was conducted to analyse the normal fatty acid profile of Malabari goat milk. Six Malabari does on the sixth day of lactation were selected to conduct the trial. Milk samples were collected fortnightly on 14^th, 28^th, 42^nd and 56^th day. Fat separation was carried out according to ISO-IDF (2001) using n-pentane and diethyl ether after adding ammonium hydroxide solution to the milk. Lipid extraction was carried out, fatty acid methyl esters were prepared and gas chromatography analysis of the samples were done. The fatty acid profile of normal goat milk from Malabari goats were elucidated. The fatty acid detected in the milk samples of were categorised to short, medium and long chain fatty acids. The fatty acids like C14:0 (Methyl Myristate) and C15:0 (Methyl pentadecanoate) showed a significant difference (p<0.01) between the fortnights with the exception of a few. Similarly, C18:1(c9) (Methyl oleate) and C18:3 (Methyl linoleate) showed a significant difference (p<0.05) between most of the fortnights. The medium chain fatty acids (MCFA) and long chain fatty acids (LCFA) exhibited a significant difference (p<0.05) between most of the fortnights.
