영장미역의 보장효과를 검토하기 위하여 생육장소, 생육시기별 성분을 조사하고 가열처리시간, 온도 및 처리액의 농도 차이가 보장효과에 미치는 영향을 검토한 결과는 다음과 같다. 1. 미역의 가공처리 적기는 포항, 여수지방은 12월 하순, 완도지방은 1월하순이었다. 2. 온도별 가열처리 효과는 $90^{circ}C$ 및 $100^{circ}C$에서 유기산, 휘발산의 증가가 비교적 적었고 색소이 감소도 적었다. 3. 농도별 가열처리 효과는, 해수와 포화식염수의 경우는 전성분 모두 저장중 큰 변화가 없었고 효과가 좋았으나 담수에서는 유기산, 휘발산이 현저하게 증가하였다. 4. 가열처리 시간별 효과는 성분변화에 큰 차이가 없었으나 20초간 처리한 것은 carotenoid의 감소가 현저 하였다. 염장 미역의 가열처리는 $90^{circ}C$ 및 $100^{circ}C$ 해수 중에서 40초간 처리하는 것이 좋았다. 본 연구는 1975학년도 문화부 학술연구 조성비로 이루어졌음.
To examine the storage effect of the dry cured cultured undaria pinnetifida, its components were researched according to different places and periods of production and in heat treatment of it, how the different time, temperature and salt concentration can effect on its storage was researched as follows. In Pohang and Yeosu districts the most suitable period of processing was around the end of December and in Wando district, around the end of January. When it was heat-treated separately at $90^{circ}C;and;100^{circ}C$ there of occurred the comparative low increase of organic acids and volatile acids, and the slight decrease of pigment. When it was heat-treated in sea water and satuarated NaCl solution, the obvious change was not found in all components, and in fresh water organic acids and volatile acids were conspicuously increased. When it was heat-treated according to the different heating time (long or short), there was no remarkable change in all components, but when heat-treated for 20 sec. the decrease of carotenoid was conspicuous. When heat-treated for 40 sec. separately at $90^{circ}C;and;100^{circ}C$ in sea water, better effect for storage was resulted.
