Headspace solid phase micro-extraction (HS-SPME) followed by gas chromatography/mass spectrometry was used to analyze the volatile composition of lards from pig fat oil and suet. Totally 46 and 27 volatile compounds were identified in lards from pig fat oil and suet, respectively. The volatile composition of lard from suet mainly consisted of n-hexadecanoic acid, oleic acid, hexanal, nonanal, octanal, 2,4-decadienal,(E,E)-, 2-octenal,(E)-, 2-nonenal,(E)-, furan,2-pentyl-, and 2-heptenal,(E)-, and the predominant volatile compounds in lard from pig fat oil were nonanal, 2-heptenal,(E)-, 2-pentadecanone, octanal, 2,4- nonadienal,(E,E)-, hexanal, 2,4-decadienal, 2-octenal,(E)- and 1-octanol.
