Taste Compounds of Rapid Processed Sardine Sauce

숙성 정어리액젓의 정미성분

In order to investigate the organoleptic properties of rapid processed sardine sauce which was prepared using sardine autolysates and sardine meal koji, the taste endowing compounds were analysed. The chemical compositions of the rapid processed sardine sauce fermented for 15 days at $40^{\circ}C$ were $1.98\%$ in total nitrogen, $1.08\%$ in amino type nitrogen, $5,296.8mg\%$ in free amino acid, and the salinity was $13.0\%$ (W/V). the predominant free amino acid in the sauce were glutamic acid, lysine, aspartic acid, valine and leucine. Those amino acids held $53.9\%$ of total free amino acids. The content of IMP was $20.8mg\%$. The rapid processed sardine sauce was comparable to traditional anchovy sauce which was fermented at ambient temperature for one year in the distribution and concentrations of nitrogenous compounds and organoleptic properties.

자가 소화액 및 정어리 기질 코오지를 마쇄 정어리 육에 첨가한 후 $40^{\circ}C$에서 15일간 발효시킨 정어리액젓은 관능적 기호성이 멸치액젓과 유사하였으며, 그 화학적 성분 조성은 총질소 $1.98\%$, 아미노태질소 $1.08\%$, 유리아미노산 $5,296.8\%$, 핵산관련물질 $131.3mg\%$, 염도는 $13.0\%$의 수준이었다. 또한 주요 아미노산으로는 glutamic acid, Lysine, aspartic acid, leucine, valine등의 함량이 높았고, IMP의 함량은 $20.8mg\%$ 수준이었다.
