Abstract
This study aims to find the taste compounds of wild loach, Misgurnis mizolepis, which is important fresh-water fish in this country. In order to elucidate the origin of the taste of wild loach meat, free amino acids, organic bases, nucleotides and their related compounds, organic acids, sugars and minerals were analyzed, and then followed by organoleptic test of synthetic extract prepared on the basis of the analytical data. Sensory evaluations of synthetic extracts prepared by omitting each extractive components were carried out by a triangle difference test, and changes in taste profile were assessed. In free amino acid composition, histidine, threonine, glycine, lysine, alanine were abundant. IMP and AMP were dominant in the wild loach in content. Total creatinine and butyric acid were abundant. As for the minerals,
미꾸라지의 정미성분을 밝힐 목적으로 미꾸라지배육중의 유리아미노산, 핵산관련물질, 유기염기, 유기산 및 무기질을 분석하고, 이 분석치를 기초로 하여 표준시약으로서 합성엑스분을 조제하여 천연엑스분과 맛을 비교하였으며 Omission test를 실시하여 각 성분들이 맛에 미치는 영향을 조사하였다. 유리아미노산의 함량은 histidine이 가장 많았고 그 외 threonine, glycine, lysine, alanine등이 많았다. 핵산관련물질은 IMP가 117.7mg/100g으로 가장 많았으며 유기염기중에는 creatinine이 353.7mg/100g으로서 가장 많았다. 유기산의 경우 브티르산이 월등히 많았으며 당류의 함량은 모두 극미량이거나 흔적량에 불과하였다. 무기질의 함량은
