Abstract

본 발명은 주로 폐기처분되는 게껍질로부터 부가가치가 높은 키틴 자원으로 활용하기 위한 것으로서, 특히 게껍질로부터 키틴을 최적조건 즉 효율적으로 분리할 수 있도록 한 분리추출방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention mainly relates to utilizing chitin resources with high added value from crab shells that are disposed of, and particularly relates to a separation and extraction method that enables the optimal separation of chitin from crab shells.

즉 수거된 게껍질을 깨끗이 세척, 건조, 분쇄한 다음 상기 분쇄된 재료를 재료 중량에 대하여 15배에 해당하는 1N HCl용액에 투입교반하면서 30분간 처리하여 재료 내에 함유된 회분을 제거하고 상기 재료를 다시 재료 중량에 대하여 15배에 해당하는 5% NaOH용액에 투입하여 65℃에서 교반하면서 1시간동안 처리하여 단백질을 제거한 다음 조키틴(탈색전의 키틴)을 얻고, 조키틴을 다시 재료중량의 10배 해당하는 0.32% NaOCl용액으로 탈색처리하므로서 게껍질로부터 키틴을 분리추출토록 하는 것이다.That is, the collected crab shells are washed, dried, and ground, and then the ground material is treated with 1N HCl solution, which is 15 times the weight of the material, and stirred for 30 minutes to remove ash contained in the material. Again, the solution was added to a 5% NaOH solution corresponding to 15 times the weight of the material and treated for 1 hour while stirring at 65 ° C. to remove the protein, to obtain a jochitin (chitin before decolorization), and the jochitin was again 10 times the weight of the material. By decolorizing with the corresponding 0.32% NaOCl solution, chitin is separated from the crab shell.
