Response to the results of the model flavor compounds was gave significance to the compound of 2,3,5,6 tetramethylpirazine, butanoic acid, 2-methoxy-phenol and ?-octalactone and not significantly different at 2, 5 dimethyl pyrazine.Keywords : cacao, fermentation, non fermented, fragrance and flavor, nurient composition</description><publisher lang="en-US">Balai Besar Penelitian dan Pengembangan Pascapanen Pertanian</publisher><contributor lang="en-US">Balai Besar Litbang Pascapanen Pertanian Jl.
