The relationship between the flavor and the heating time of niboshi-soup (extract of dried small sardine) was examined by sensory evaluation. During the heating of niboshi-soup, it was observed from panel scores that the flavor turned to be more preferable.Volatile, neutral and basic components in the head space vapor of niboshi-soup were investigated by gas chromatography and thin layer chromatography. The volatile neutral components of unheated and heated niboshi-soup were identified as follows; paraffins (C4-C8), n-aldehydes (C2-C6), iso-butyraldehyde, n-alcohols (C1, C3, C4) and iso-alcohols (C3, C4). The volatile basic components were ammonia, dimethylamine and trimethylamine. The amounts of most of these volatile components decreased during the heating.It appears that the decrease of the low-boiling volatile components contributes to the increased flavor acceptability of the heated niboshi-soup.
