Abstract: <i>Pediococcus acidilactici </i>UP02<i> </i>was used as a starter for the fermentation of tempoyak (<i style="">Durio zibethinus</i> Murr.), a traditional Indonesian fermented fruit. The flavour of tempoyak was compared to those in spontaneous fermentation (no starter added). The results showed that addition of <i style="">P. acidilactici</i> UP02 in tempoyak fermentation decreased the quantity of sulphur components, reduced the sugar content, and increased various non-sulphur compounds as well as, non-volatile acidity and contents of organic acids (lactic, malic, and acetic). Sensory evaluation showed that there was no significant difference among the samples for sourness and aroma. However, the <i style="">P. acidilactici </i>UP02-inoculated sample was more acceptable than the sample with no-starter treatment. On the basis of the results of GC-MS, the flavour components of tempoyak with <i style="">P.</i> <i style="">acidilactici</i> UP02 treatment were observed to have 48 compounds, mainly composed of dimethyl disulfide and diethyl disulfide followed by ethane,1-1-bis ethylthio.
