흡착법을 이용한 어유의 탈취

Deodorization of Fish Oil Using Adsorption Method

초록

어유의 탈취장치 대신 컬럼에 활성탄, 활성 알루미나, 실리카겔, 대나무 숯 등 흡착제를 단독 혹은 적당한 비율로 혼합하여 충진시켜 탈색과 동시에 탈취시킴으로서 효율적인 탈취효과를 검토하였다. 대멸치유의 탈검효과는 수산 30%를 어유 100 ml에 대하여 18 ml첨가한 것이, 탈산은 수산화 나트륨을 2.5%로 하여 $40^{\circ}C$에서 30분간 처리한 것이 효과적이었다. 탈취의 경우 흡착제(활성탄, 활성알루미나, 실리카겔)를 농도별로 단독 첨가할 경우는 실리카겔30% 첨가가, 그리고 흡착제를 혼합하여 첨가할 경우는 활성알루미나 30%와 실리카겔 10% 혼합 첨가가 가장 우수하였으나 흡착제에 녹차분말 2%를 첨가할 경우 큰 효과가 없었다. 대멸치유의 탈검, 탈산 및 탈취 후의 주요지방산 조성은 16:0, 20:5n-3, 18:1n, 16:1n-7, 22:6n-3 및 18:0이었다. 대멸치 정제유에 $\alpha$-tocopherol를 첨가하여 $25^{\circ}C$에서 40일간 저장시 산화 안정성은 대조구는 20일까지 항산화제를 첨가한 경우는 30일까지라 생각되며 $\alpha$-tocopherol 0.02%첨가보다 0.01% 첨가가 더 효과적이었다.

Abstract

Instead of deodorization appararus of fish oil, an adsorbent such as activated charcoal, activated alumina, silicagel, bamboo charcoal was packed in column alone or mixed with preparative ratio, and then test the effective deodorization with bleaching. In the progress of degumming, the effective method was 18 ml of 2.5% oxalic acid per 100m1 of crude large anchovy oil. The optical condition to deacidified was treating for 30 min at $40^{\circ}C$ with 2.5% sodium hydroride solution. The effective deodorization was added with 3% silicagel under the alone treating adsorbent, and mixed treating was 30% activated alumina and 10% silicagel but added to green tea powder was not effective. The major fatty acid of total lipid were 16:0, 20:5n-3, 18:1n-9, 16:1n-7 and 22:6n-3 after treatment of degumming, deacidfication and deodorizing in the large anchovy oil. The oxidative stability of refined anchovy oil added to $\alpha$-tocopherol was validated 20 days under the control, and 30 days in the case of $\alpha$-tocopherol. The 0.01% $\alpha$-tocopherol was more effective than 0.02% $\alpha$-tocopherol.
