A tentative characterization of volatile compounds from Iberian Dry-Cured Ham according to different anatomical locations. A detailed study | Una tentativa de caracterización de los compuestos volátiles del jamón curado Ibérico según su localización anatómica. Un estudio detallado

anglais. 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).

espagnol; castillan. El objetivo de este trabajo fue llevar a cabo una caracterización de la fracción volátil de 23 jamones curados de cerdo ibérico mediante GC-ion-trap-MS. Se analizaron dos zonas diferentes de las lonchas tomadas paralelas al fémur de cada jamón, Grasa subcutánea y magro. El análisis se realizó mediante cromatografía gaseosa en columna capilar de alta polaridad con detección de espectrometría de masas y extracción previa de la fracción volátil mediante purga y trampa. Un total de 109 compuestos volátiles fueron identificados, veintiocho de ellos descritos por primera vez en Jamón ibérico curado (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-methyl-ethyl)-cyclopentanone, 3,5-octadien-2-one, 2-hydroxymethyl-2,3,3-trimethyl-oxirane, 2-ethyl-hexyl 2-propenoate, 1-methoxy-pentane, 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).
