The volatiles of whole and homogenated tomato fruits collected by the headspace trapping method using Tenax GC and the simultaneous steam distillation method were identified by GC and GC-MS. Among over 100 GC peaks, 10 alcohols, 6 aldehydes, 4 ketones, 3 esters, 1 phenol and 1 acid were identified from hole tomato fruits, whereas 12 alcohols, 6 aldehydes, 5 ketones, 5 esters, 2 phenols, 1 hydrocarbon and 1 acid were identified from homogenated tomato fruits. By simultaneous steam distillation-extraction, 19 alcohols, 13 hydrocarbons, 9 esters, 9 ketones, 8 aldehydes, 2 phenols, 2 lactones, 2 furans, 1 acids and 2 others were identified among over 300 peaks.
