|Abstract:||Pediococcus acidilactici UP02 was used as a starter for the fermentation of tempoyak (Durio zibethinus 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 P. acidilactici 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 P. acidilactici 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 P. acidilactici UP02 treatment were observed to have 48 compounds, mainly composed of dimethyl disulfide and diethyl disulfide followed by ethane,1-1-bis ethylthio.|
