Abstract

This study was carried out to prepare the flavoring substance using sardine for instant soup, and to examine the taste compounds and storage stability of the product. In preparation of product, raw sardine are gutted, boiled for 10 minutes and smoked 3 times to $9{\sim}10%$ moisture content at $80^{\circ}C$ for 8 hours. The smoked-dried sardine meat were followed to be 50 mesh of particle size. The powdered-dried sardine were mixed 4.0% sugar, 20.0% table salt, 3.0% monosodium glutamate, 0.2% black pepper, 0.2% garlic powder and 0.2% onion powder, Finally the powdered instant soup product were vacuum packed in a laminated film(PET/A1 foil/CPP) bag, and then stored at room temperature for 120 days. The effect of smoking on enhancing flavor and on preventing lipid oxidation of product during storage were observed. From the chemical analysis and omission test, the principal taste compounds of product were IMP, 478.2mg/l00g; free amino acids such as glutamic acid, histidine, arginine, phenylalaine 3292.5mg/l00g; non-volatile organic acids such as lactic acid, ${\alpha}-ketoglutaric$ acid, 712.2mg/l00g; total creatinine 409.0mg/100g, and small amount of betaine, TMAO. Fatty acid composition of product were mainly consisted of polyenoic acids such as 20:5, 22:6, followed by saturated acids, monoenoic acid. The major fatty acid were 16:0, 16:1, 18:1, 20:5 and 22:6. From the results of sensory evaluation and chemical experiments during storage, the vacuum packed product were good condition for preserving the quality during storage for 120 days. We may conclude that the quality of present product was not inferior to that of seasoning powder of anchovy on the market, and it can be commercialized as a flavoring substance in preparing soup and broth.

새로운 풍미계 조미료를 개발할 목적으로 정어리를 원료로 하여 우리나라 사람의 기호에 맞고 즉석수우프로 이용할 수 있는 정어리분말수우프의 제조를 시도하였다. 생정어리의 내장을 제거한 후 자숙하여 일부 피하지방을 제거하고 훈연실에서 8시간$(80^{\circ}C)$ 훈연한후 실온에서 15시간 엄증하는 조작을 3차례 반복하였다. 이를 분쇄기로써 50 mesh 크기로 분쇄한 다음 여기에 설탕 4.0%, 식염 20.0%, Na-glutamate 3.0%, 후추가루 0.2%, 마늘가루 0.2% 및 양파가루 0.2%를 첨가하여 PET/AI foil/CPP 적층필름에 충전한 후 진공포장하였다. 제품제조시 훈연처리는 제품의 풍미향상 및 지질의 산화방지에 효과적이었다. 정어리분말수우프제품의 수분함량은 $9{\sim}10%$, 조지방함량은 7% 내외이었고, 아미노질소량은 $67.5{\sim}72.5mg/100g$이었다. 주요한 정미성분으로는 1MP가 478.2mg/100g, glutamic acid(2168.4mg/100g), histidine, argnine, alanine, phenylalanne 등 유리아미노산이 329.5mg/100g, lactic acid(576.9mg/100g), ${\alpha}-ketoglutaric$ acid 등 불휘발성 유기산이 712.2mg/100g 함유되어 있었다. 이외에 total creatinine이 409.0mg/100g, 미량의 betaine 및 TMAO로 이루어져 있었다. 정어리분말수우프의 정미성분을 열수로 추출하여 omision test 및 관능검사한 결과 맛 성분에의 기여도는 핵산관련물질, 유리아미노산, 유기산 순이었고 본 시제품을 시판멸치분말 수우프와 비교할 때 손색이 없었다. 지방산조성은 $C_{20:5}$$C_{22:6}$을 주체로 한 폴리엔산이 전체의 43.3%를 차지하였고 다음이 포화산(36.0%), 모노엔산(20.7%) 순이었다. 주된 구성지방산은 $C_{16:0},\;C_{16:1},\;C_{18:1},\;C_{20:5},\;$$C_{22:6}$ 등이었다. 제품저장중 품질안정성에 대해 검토한 결과 진공포장함으로서 저장중 지질산패, 갈변 등 품질저하를 억제시킬 수 있었다.
