A tentative characterization of volatile compounds from Iberian dry-cured ham according to different anatomical locations. A detailed study

Abstract

The aim of this work was to carry out a characterization of the volatile fraction of 23 Iberian dry-cured hams by GC-iontrap- MS. Two different locations -subcutaneous fat and musclefrom the slices taken parallel to the femur from each ham were analyzed. The analyses were done by Gas Chromatography-Mass Spectrometry with a polar capillary column and after a previous extraction using the Purge and Trap method. A total of 109 volatile compounds were identified, twenty-eight of which for the first time in Iberian dry-cured ham (isopropanol, 4-methyl-5-decanol, 2-butyl-1-octanol, 2-etoxy-ethanol, 2-ethyl-phenol, 2-hexen-1-ol, 3,5-octadien-2-ol, 2-decen-1-ol, 5-ethylcyclopent-1- enecarboxaldehyde, 2,4-heptadienal, 6-nonenal, cyclopentanone, 3-ethenyl-cyclohexanone, 2-methyl-cyclopentanone, 6-octen-2-one, 5-methyl-2-(1-methylethyl)-cyclopentanone, 3,5-octadien-2-one, 2-hydroxymethyl-2,3,3-trimethyl-oxirane, 2-ethyl-hexyl 2-propenoate, 1-methoxypentane, 2,3-dihydrofurane, 2-D-2-pentadecyl-1,3-dioxolane, hexyl octyl eter, eucalyptol, di-(3-methyl-buthyl) eter, piperidine, isopropylamine and 2-ethenyl-pyridine).
