Volatiles of durian pulp from different cultivars in Thailand, Malaysia and Indonesia were already reported. However, no study of volatiles from Philippine ＂Puyat＂ durian is available. ＂Puyat＂ is the most preferred by consumers in the Philippines due to its firm flesh with sweet and buttery taste. Aroma volatile compounds were analyzed by headspace solid phase microextraction （HS-SPME） method and gas chromatography-mass spectrometry （GC-MS）. Volatiles were extracted for 1 h using 65 μm PDM/DVB SPME fiber and separated by DB-WAX capillary column （30 m × 0.25 mm id × 0.25 μm film thickness）. Durian pulp produced 22 volatiles composed of 15 esters, six sulfurs and one thioacetal. Ethyl propanoate, ethyl octanoate, propyl propanoate, ethyl 2-methyl butanoate and diethyl disulfide were the major compounds identified. These compounds were also reported to be the most abundant in durian cultivars of other countries. Results of this study can then be used for future development of postharvest technologies to control the production of volatiles from Philippine durian pulp.展开更多
