Abstract

This study indicated that mackerel flesh can be prepared as an intermediate moisture deep-fried product. The fillet were cut into $2{\times}2{\times}1.5cm$ (about 4g each): then submerged in an infusion solution (lg flesh: 1ml solution) containing 45.9% of water, 6% of sodium chloride, 40% of sorbitol, 2.4% of propylene glycol, 0.7% of potassium sorbate, 3% of sugar, 2% of monosodium glutamate, and $0.6m{\ell}$ of alcoholic extracts from red pepper, and heated for 10 min at $105^{\circ}C$. The infused flesh was drained for 15 min and then coated with batter and crumb. The pieces were deep fried in soybean oil for 3 min at $170^{\circ}C$ and cooled on absorbent paper. The initial water activity of the product was 0.86. Judging from the results of experimental data such as peroxide value, TBA value, viable cell count and sensory evaluation, the quality of products were stable for 50 days at room temperature ($25{\pm}2^{\circ}C$).

어육을 이용한 중간수분식품의 제조를 위한 기초 자료를 얻을 목적으로 고등어육을 원료로써 튀김중간수분식품의 가공조건을 검토하고, 그 최적조건으로 중간수분식품을 제조하여 함기(含氣)포장한 후 상온($25{\pm}2^{\circ}C$)에 저장하면서 품질변화를 검토하였다. 고등어 튀김중간수분식품의 가공조건은 물 45.9%, 식염 6%, sorbitol 40%, propyleneglycol 2.4%, 솔빈산칼륨 0.7%, 설탕 3%, 글루탐산나트륨 2%, 고추 가루 추출물 0.6ml로 된 침지용액에 고등어 육편을 넣어 $105^{\circ}C$에서 10분간 가열하고난 후 식혀서 빵가루를 입히고 $170{\pm}5^{\circ}C$의 기름에서 3분간 튀김하는 것이었다. 위와같은 가공조건에서 제조한 제품은 수분활성 0.86이었고, 저장 중의 품질변화를 과산화물값, TBA값, 색조, 생균수 및 관능검사 등으로 평가한 결과 상온($25{\pm}2^{\circ}C$) 저장 50일까지 품질에 큰 손상없이 저장 할 수 있다는 결론을 얻었다.
