The results indicated that the odor activity values (OAVs) of five aldehydes and two ketone were higher, and their contents in lean meat from Changbai Mountain black pig were significantly higher than in lean meat from lean-type pig. The OAVs of hexanal, heptanal, octanal, decanal and (E)-2-nonenal were higher, which caused the flavor difference between the breeds. The OAVs of acet
