Abstract

As the studies on effective utilization of polyunsaturated lipids in sardine (Sardinops melanosticta), the conditions of deacidification, decoloring, and deodorization for processing of refined sardine oil were investigated In the process of refining, phosphoric acid treatment was not effective in removing phosphatides, and optimal condition to neutralize the crude sardine ill was treating for 30min at $40^{\circ}C$. with $0.5\%$ excess of 3M NaOH solution. Decoloring was optimized by adding $5\%$ bleaching earth and treating for 20min at $50^{\circ}C$ under vacuum, and deodorizing was done by steam destillation at $180^{\circ}C$ under 3 torr of vacuum. When deodorizing temperature exceeded $200^{\circ}C$, some changes occured in fatty acid composition and artifacts were appeared on GLC chromatogram.

정어리유의 고도불포화지질을 일상식생활을 통하여 효과적으로 이용하기 위하여 정제정어리건의 제조를 위한 탈산, 탈색, 탈취 등의 정제조건을 검토한 결과를 요약하면 다음과 같다. 1. 정어리유의 탄산은 알칼리처리가 효과적이었으며 2M NaOH용액을 $0.5\%$ 과잉첨가하고 $30^{\circ}C$, 30분처리가 적조건이었다. 일반적으로 행하는 인산처리는 탈검에 효과가 없었다. 2. 탈색은 산성백토만을 기름의 $5\%$정도로 첨가하고 감압하에서 $60^{\circ}C$ 20분간 처리하는 것이 가장 효락적이었다. 3. 탈취는 수증기증류가 효과적이었으며 4torr 이하로 감압하면서 $180^{\circ}C$ 이하의 온도에서 하는 것이 바람직하였고 $200^{\circ}C$ 이상에서는 현저한 요오드가의 감소와 지방산조성에 변화를 초래하였다.
