摘要:

采用顶空- 固相微萃取法提取猪板油和猪肥油的挥发性成分,用气相色谱- 质谱进行分离鉴定。实验结果显示,两种猪脂中分别鉴定出46 种和27 种挥发性成分。猪板油中的主要挥发性成分是棕榈酸、油酸、己醛、壬醛、辛醛、(E,E)-2,4- 癸二烯醛、(E)-2- 辛烯醛、(E)-2- 壬烯醛、2- 戊基呋喃、(E)-2- 庚烯醛等;而猪肥油中的主要挥发性成分是壬醛、(E)-2- 庚烯醛、2- 十五酮、辛醛、(E,E)-2,4- 壬二烯醛、己醛、2,4- 癸二烯醛、(E)-2- 辛烯醛、1 - 辛醇等。

Abstract:

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.

Key words: leaf fat, suet, HS-SPME, GC-MS, volatile compounds
