In this study, the emission patterns of reduced sulfur compounds (RSC) were investigated using four different types of food samples (boiled egg, milk, canned meat and strawberry) between fresh and decaying stages. To this end, the concentrations of RSCs were measured at storage days of 0, 1, 3, 6, and 9 under room temperature. Four sulfur compounds (H₂S, CH₃SH, DMS and DMDS) were selected as target compounds along with two reference compounds (CS₂ and SO₂). Their concentrations were quantified using GC-PFPD equipped with thermal desorption (TD) system. The boiled egg showed the highest concentration of H₂S (3,655 ppb) at D-1, while CH₃SH reached its maximum value of 64.4~78.5 ppb after 3 days. In milk samples, concentration of CH₃SH, DMS, and DMDS went up to 487, 16.3, and 578 ppb, respectively with the progress of decay (D-9). In case of canned meat, concentration of H₂S and CH₃SH peaked in the beginning (D-0) such as 345 and 66.6 ppb. In case of strawberry, CH₃SH and DMDS showed the maximum concentrations 135 and 50.5 ppb at D-1, respectively. The olfactometry dilution-tothreshold (D/T) ratio by air dilution sensory (ADS) test showed similar patterns when sum of odor intensity (SOI) was derived via conversion of odorant concentration data. The results of this study confirm that the time of strong RSC emissions is distinguished for each food type between fresh (e.g., strawberries) and decaying conditions (e.g., milk).
