Chicken Flavor: the Identification of Some Chemical Components and the Importance of Sulfur Compounds in the Cooked Volatile Fraction

摘要

SUMMARYMeat and water slurries of both leg and breast muscle from heavy hens were cooked in a nitrogen atmosphere. Some of the chemical components in the volatile fraction were identified by solubility classification, derivative preparation, and/or functional group analysis in combination with gas chromatography and/or qualitative chemical analyses and odor evaluation. Twenty‐nine compounds in the volatiles from leg muscle and 25 compounds from breast muscle were identified by the functional‐group trapping technique followed by gas chromatography of the effluent fractions. Qualitative chemical tests revealed 19 major classes of compounds and a few specific compounds.Removal of sulfur compounds resulted in an almost complete loss of “meaty odor” in both dark and light meat. Removal of the carbonyls from the volatile fraction resulted in a loss of “chickeny‐flavor” and intensification of the “meaty or
