چکیده انگلیسی
Despite studies on umbelliferous fruits flavor makeup, nothing is known regarding roasting impact on their fruit aroma. Five major umbelliferous crops viz., anise, caraway, coriander, cumin and fennel were analyzed via headspace solid-phase microextraction to reveal for 117 volatile constituents. Oxygenated monoterpenes amounted for the major volatile class in raw fruits at 75% with (E)-anethole, carvone, β-linalool, cuminaldehyde and estragole as major components in anise, caraway, coriander, cumin, and fennel, respectively. Difference was observed in fennel fruit “estragole” levels derived from different origins. Upon roasting, several novel volatiles were detected viz. pyrazines and flavored Milliard type volatiles. Major flavor intensified response was detected in cumin with an increase in its “cuminaldehyde” levels versus a decrease of estragole levels in fennel. Roasted cumin exhibited highest peroxide value 14.2â¯mEq O2/Kg, whereas the least was detected in fennel at 6.1â¯mEq O2/Kg, though with both values not representing a health hazard.
