In this study, chitin was exclusively extracted from shrimp shells (Marsupenaeus japonicas) through a green solvent called deep eutectic solvent (DES), and various types of DES were utilized to extract chitin. The physicochemical properties of the obtained chitin were compared with the conventional method. A high purity of chitin was obtained while using DES-8 (choline chloride-malonic acid) with a yield of 19.41% ± 1.35%, and purity was confirmed using C nuclear magnetic resonance. The DES-produced chitin was utilized to produce chitin films and was compared with standard chitin films. The obtained films were characterized by SEM, AFM, TGA, DSC, FTIR, mechanical properties, moisture sorption, swelling behavior, and biodegradation. The DES film showed similar properties to the standard film, while the mechanical properties, swelling behavior, and biodegradation of the DES chitin films proved to be similar to standard chitin film. These chitin films can be used as wound healing resources.
在这项研究中，甲壳素是通过一种名为深共晶溶剂（DES）的绿色溶剂从虾壳（日本沼虾）中专门提取出来的，并且使用了各种类型的 DES 来提取甲壳素。对获得的甲壳素的物理化学性质与传统方法进行了比较。使用 DES-8（氯化胆碱-丙二酸）获得了高纯度的甲壳素，产率为 19.41%±1.35%，并使用 C 核磁共振进行了纯度确认。用 DES 生产的甲壳素用于生产甲壳素薄膜，并与标准甲壳素薄膜进行了比较。通过 SEM、AFM、TGA、DSC、FTIR、力学性能、吸湿性、溶胀行为和生物降解对获得的薄膜进行了表征。DES 薄膜表现出与标准薄膜相似的性能，而 DES 甲壳素薄膜的力学性能、溶胀行为和生物降解性能与标准甲壳素薄膜相似。这些甲壳素薄膜可用作伤口愈合资源。
