The aim of this work was to determine the flavor active compounds of rambutan seed fat (RSF) and its mixtures with cocoa butter (CB) after fermentation 6 days and roasting at 150 C for 30 min in term of ester, alcohol, hydrocarbon, carboxylic acid, aldehyde, ketone and pyrazine compounds. The result showed total ester flavoring compounds increased in the range of – in the RSF mixtures as compared to CB,.Invite you to consult the documentation. | Journal of King Saud University – Science xxx (2017) xxx–xxx Contents lists available at ScienceDirect Journal of King Saud University – Science journal homepage: Identification of flavor compounds in rambutan seed fat and its mixture with cocoa butter determined by SPME-GCMS q H.

The industrial processing of this fruit produces seeds and peels as waste materials. The aim of this work was to determine the flavor active compounds of rambutan seed fat (RSF) and its mixtures with cocoa butter (CB) after fermentation 6 days and roasting at 150 °C for 30 min in term of ester, alcohol, hydrocarbon, carboxylic acid, aldehyde, ketone and pyrazine compounds. The result showed total ester flavoring compounds increased in the range of – in the RSF mixtures as compared to CB. Alcoholic flavoring compounds also found in the range of – of the total flavor in CB and RSF mixtures respectively. The most important flavoring compounds, Pyrazine, 2,6-dimethyl ( and ), Pyrazine, 2-ethyl-6-methyl ( and ), .
