Abstract

To produce high quality fish oil products, additional deodorization experiments on purified fish oil from squid using columns filled with citric acid or gluconic acid were performed. A deodorization effect on the fish oil was observed on both the citric acid and gluconic acid columns. These effects were more efficient on the columns packed with 3 g of organic acid than those with 1 g or 2 g of organic acid. In addition, a better effect was observed in the column packed with gluconic acid than that with citric acid. Peroxide value (POV) and acid value (AV) of the sample treated with citric acid was the as same as the non-treated sample. However, POV and AV of the sample treated with gluconic acid were about 10% higher than the non-treated sample. Contents of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) of the samples treated with citric acid or gluconic acid columns were about 0.5% higher than the non-treated sample. In conclusion, deodorization of squid fish oil by organic acid could be an efficient method to produce high quality fish oil products.

오징어 정제어유에 대한 부가적인 탈취과정을 통해 고품질의 제품을 생산하기 위하여 유기산의 일종인 citric acid 및 gluconic acid를 이용한 칼럼을 제작하고 여기에 오징어 정제어유를 통과시키는 방법으로 어취제거 실험을 행하였다. 그 결과, citric acid 및 gluconic acid 칼럼 모두에서 우수한 어취제거 효과가 나타났으며, 유기산 1 g과 2 g을 사용한 경우보다 3 g을 사용한 경우에 더 우수한 어취제거 효과를 얻을 수 있었다. 또한, citric acid를 사용한 칼럼에서 보다 gluconic acid를 사용한 칼럼에서 더 높은 어취제거 효과를 얻을 수 있었다. 한편, 과산화물가(POV) 및 산가(AV)를 측정한 결과, gluconic acid칼럼을 통과한 시료는 미처리 대조군에 비해 약간 높은 수치를 나타냈으며, citric acid 칼럼을 통과한 시료는 미처리 대조군과 비슷한 수치를 나타냈다. 결론적으로, gluconic acid 칼럼을 이용한 탈취실험의 경우는 탈취효과는 뛰어난 반면 과산화물가와 산가가 약간 증가하는 결과가 나타났고, citric acid칼럼을 이용한 탈취실험의 경우는 탈취효과는 약간 떨어졌지만 과산화물가와 산가는 미처리 대조군과 비슷한 수치를 나타냈다. 본 연구에서 유기산 칼럼을 이용하여 성공적인 어취제거효과를 얻을 수 있었으며, 어유의 주요 성분 변화는 거의 관찰되지 않음을 확인할 수 있었다.
