Abstract
Chitin was isolated from red snow crab (Chinonecetes japonicus) and deacetylated by boiling alkaline solution to produce chitosan. The physical properties of chitosan solution and its film properties was examined, As the molecular weights of chitosan was increased from 297Kpa to 319Kpa, the tensile strength, degree of elongation and water permeability of chitosan film were increased. As the degree of deacetylation of chitosan was increased, the tensile strength, the degree of elongation and water permeability of chitosan film were increased. As the concentration of chitosan solution was increased, the degree of elongation and water permeability of film were increased, whereas the tensile strength of film was decreased, As the pH of chitosan solution was increased, the tensile strength and water permeability of film were decreased, whereas the degree of elongation of film was increased.
Chitosan을 이용하여 필름을 제조하여 chitosan의 탈아세틸화도와 분자량, chitosan의 농도, pH등에 따른 chitosan 필름의 인장강도, 인장율 및 수분 투과도 등을 조사한 결과는 다음과 같다. Chitosan 조제조건으로는
