Abstract

Extracción de la quitina en una etapa única por hidrólisis enzimática en medio ácido La presente invención se refiere a un método para la extracción enzimática de la quitina, caracterizado porque dicho método se realiza en un solo paso en el que la quitina se obtiene por hidrólisis enzimática de la materia prima constituida por biomasa animal, que comprende quitina, dicha hidrólisis enzimática utiliza una enzima activa en medio ácido. La invención también se refiere a un proceso de optimización de dicho método de extracción enzimática de la quitina. La invención se refiere además a las quitinas susceptibles de ser obtenidas por dicho método de extracción enzimática
