Abstract
The physicochemical properties of chitin and chitosan produced from lobster shrimp (Metanephrups thomosonii) shell were investigated. Lobster shrimp chitin contained 6.84% nitrogen, 0.57% fat and 0.32% ash, while chitosan contained 7.52% nitrogen, 0.13% fat and 0.33% ash. Degree of deacetylation and molecular weight of chitosan were 67.5% and
가시발새우 껍질을 부가가치가 높은 자원으로 활용하기 위하여, 이들로부터 키틴과 키토산을 제조하여 물리화학적 특성을 살펴 보았다. 가시발새우 껍질에서 추출한 키틴의 일반성분은 질소 6.84%, 지방 0.57%, 회분 0.32%였으며, 수율은 15.7%였다. 키토산은 질소함량이 7.52%였으며 지방과 회분함량은 각각 0.13%와 0.33%였다. 그리고 탈아세틸화도는 67.5%, 분자량은
