Summary: | Headspace solid-phase microextraction (SPME) with an 85 µm
Carboxen polydimethylsiloxane (CAR/PDMS) fiber was used to extract
volatile compounds, and a gas chromatograph equipped with a mass
spectometry detector (GC-MS) was used to identify the volatile
compounds in honeys. Thirty-four different volatile compounds from the
headspace of honey produced in the central valley of Ñuble
Province, Chile, were extracted with fiber coating CAR/PDMS. The
identified compounds were: 10 alcohols, 9 acids, 6 ketones, 3
aldehydes, 2 furans, 2 terpenes and 2 lactones. Only four of the
volatile compounds had never been reported before as honey compounds;
these being: 1,3-propanodiol, 2-methyl butanoic acid,
3,4-dimethyl-3-hexen-2-one, and 6-methyl-5-octen-2-one. These four
compounds were found in three of the 10 analyzed samples. The compounds
found in the highest percentage of area were ethanol, acetic acid,
1-hydroxy-2-propane, 3-hydroxy-2-butane, and furfural. However, the
analyzed samples did not present a distinctive profile.
La extracción de compuestos volátiles desde el espacio de
cabeza de mieles se realiza mediante microextracción en fase
sólida (SPME), utilizando una fibra de 85 µm de Carboxen
polidimetilsiloxano (CAR/PDMS), el análisis de los compuestos
volátiles se realiza mediante cromatografía de gases con
detector de masa (GC-MS). Un total de 34 diferentes compuestos
volátiles fueron extraídos desde el espacio de cabeza de
mieles provenientes del valle central de la provincia de Ñuble con
la fibra de CAR/PDMS. Los compuestos identificados fueron 10 alcoholes,
9 ácidos, 6 cetonas, 3 aldehídos, 2 furanos, 2 terpenos y 2
lactonas. De los compuestos volátiles sólo tres no han sido
reportados con anterioridad en mieles, estos compuestos fueron:
1,3-propanodiol, ácido 2-metil butanoico,
3,4-dimetil-3-hexen-2-ona, 6-metil-5-octen-2-ona. Estos cuatro
compuestos se encontraron en sólo tres de las 10 muestras
analizadas. Los compuestos que se encontraron en un mayor porcentaje de
área fueron etanol, acido acético, 1-hidroxi-2-propano,
3-hidroxi-2-butano y furfural; sin embargo, las muestras analizadas no
presentan un perfil aromático característico. |
