Abstract:
Volatile odor compounds of ground dark roasted Arabica coffee beans from
Chiang Rai province were extracted by using solid phase microextraction (SPME) prior
analysis by gas chromatography-mass spectrometry. Three fibers with different polarity
including divinylbenzene/carboxen/polydimethylsiloxane (DVB/CAR/PDMS),
polydimethylsiloxane (PDMS) and carboxen/polydimethylsiloxane (CAR/PDMS) were
investigated for extraction of volatile odor constituents. Fifteen low polar compounds were
detected with PDMS fiber. The key odor volatiles were sotolone, decanal and cis-pinocarvyl
acetate, while twenty high polar constituents were found when using CAR/PDMS fiber with
the major compounds of indole, 2-furanmethanol, sotolone and acetic acid. For
DVB/CAR/PDMS fiber which can be extracted with board range of chemical compounds,
twenty-eight compounds were investigated. The major volatiles were 2-furancarboxaldehyde,
2-furanmethanol, sotolone and larixinic acid. Different amounts of volatile odor components
of ground dark roasted Arabica coffee beans from Chiang Rai were related to chemical
composition on each fiber. The DVB/CAR/ PDMS fiber was considered to be the best fiber
for extraction of odor volatiles of ground roasted Arabica coffee beans due to the highest
number of detected volatile components compared to other fibers. It is noted that the solid
phase microextraction technique is more sensitive to extract the volatile components which
played the significant role as the key scent in dark roasted Arabica coffee beans.
