The Isolation of Taurine from the Oyster Shucking Juice Using Ion Exchange Column Chromatography

이온교환크로마토그라피를 이용하여 굴 박신액에서 Taurine의 분리

The study was attempted to isolate taurine from the oyster shucking juice known as one of the by-products of oyster processing using ion exchange column chromatography. Three hundred grams of the oyster shucking juice were loaded onto a column packed with 300 ml of the Dowex 50W $H^+$ form. And taurine-rich fractions were further purified in columns packed with 150 ml of Dowex 2 OH form and the 150 ml of Amberite IRA-410 OH form consecutively. The purity and the yield of taurine recovered from the oyster shucking juice by this method were 94.7% and 84.8%, respectively.

본 연구에서는 효과적으로 이용하지 못하는 굴박신액에서 이온교환 크로마토그라피로 taurine의 분리하고자 하였다. Dowex 50W $H^+$형과 Dowex 2 OH 형으로 처리한 용출액 중 흡광도가 높게 나타난 획분을 Amberite IRA-410 $OH^-$형에 다시 용출시켜 taurine을 흡착시킨 후 흡착한 taurine을 0.1M acetic acid로 용출시키면 수율과 순도가 84.8%와 94.9%인 taurine을 얻을 수 있었다.
