| Abstract: | The fatty acid profiles of black and white peanuts were analyzed and compared.The lipid fractions in black and white peanuts were extracted by Soxhlet extraction,followed by esterification with a potassium hydroxide/methanol solution.The fatty acid methyl esters(FAME)were analyzed by gas chromatography-mass spectrometry(GC-MS).A total of 19 and 17 fatty acids were identified in black and white peanuts,respectively.Unsaturated fatty acids represented 61.07%and 67.59%of the total fatty acids in black and whit... |
