Volatile Compounds in Honey Produced in the Central Valley of Ñuble Province, Chile

Headspace solid-phase microextraction (SPME) with an 85 µm polydimethylsiloxane (CAR/PDMS) fiber was used to extract compounds, and a gas chromatograph equipped with a mass detector (GC-MS) was used to identify the volatile in honeys. Thirty-four different volatile compounds from the of honey produced in the central valley of Ñuble, Chile, were extracted with fiber coating CAR/PDMS. The compounds were: 10 alcohols, 9 acids, 6 ketones, 3, 2 furans, 2 terpenes and 2 lactones. Only four of the compounds had never been reported before as honey compounds; being: 1,3-propanodiol, 2-methyl butanoic acid,3,4-dimethyl-3-hexen-2-one, and 6-methyl-5-octen-2-one. These four were found in three of the 10 analyzed samples. The compounds in the highest percentage of area were ethanol, acetic acid,1-hydroxy-2-propane, 3-hydroxy-2-butane, and furfural. However, the samples did not present a distinctive profile.
