The study found that the fermentation treatment followed by roasting treatment significantly increase the browning index and melanoidin content in powder and fat, respectively. Six and 9 days fermentation followed by roasting possessed highest value of browning index ( and AU, respectively) and melanoidin content,.

Previous finding showed that rambutan seed could be utilized by extracting the fat that could be utilized as confectionery fat with improved characteristic by fermentation and roasting treatment. The study to evaluate the cocoa-like flavor compounds development as the effect of these process was carried out. The rambutan seed was fermented for 3, 6, and 9 days followed/unfollowed by roasting process at 150°C for 30 min. The browning index of the powder, the Maillard Reaction Products (MRPs) and the volatile flavor compounds of the rambutan seed fat were analysed. The study found that the fermentation treatment followed by roasting treatment significantly increase the browning index and melanoidin content in powder and fat, respectively. Six and 9 days fermentation followed by roasting possessed highest value of browning index ( and AU, respectively) and melanoidin content ( and AU, respectively). The result also showed that fermentation of rambutan seed followed by roasting process could successfully developed desired pyrazine compounds, in which the contribution of the pyrazine content could be as much as of total flavor compound of rambutan seed fat.
