Resumen
HEADSPACE SOLID-PHASE MICROEXTRACTION (SPME) WITH AN 85 ÊM CARBOXEN POLYDIMETHYLSILOXANE (CAR/PDMS) FIBER WAS USED TO EXTRACT VOLATILE COMPOUNDS, AND A GAS CHROMATOGRAPH EQUIPPED WITH A MASS SPECTOMETRY DETECTOR (GCMS) 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 NUBLE 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.
