This is the first report on the physicochemical properties of chitin obtained from larvae and imagoes of black soldier flies (Hermetia illucens). Scanning electron microscopy revealed differences in surface morphologies of the two types of chitin. The crystalline index values of chitins from adult flies and larvae were 24.9% and 35%, respectively. This is a trait that differentiates these biopolymers from chitins extracted from other sources described so far. X-ray diffraction patterns and IR spectroscopy revealed that both types of samples of chitin were in an α crystalline form. Also, the results of elemental analysis, thermal stabilities and FTIR spectroscopy of the chitins from larvae and adults of H. illucens were similar, which points to a general similarity in their physicochemical structure.
这是关于从黑水虻（Hermetia illucens）幼虫和成虫中提取的几丁质物理化学性质的首份报告。扫描电子显微镜显示这两种几丁质的表面形态存在差异。成年黑水虻和幼虫的几丁质结晶指数值分别为24.9%和35%。这是将这些生物聚合物与迄今所描述的从其他来源提取的几丁质区分开来的一个特征。X射线衍射图谱和红外光谱表明，两种几丁质样品均为α晶型。此外，黑水虻幼虫和成虫的几丁质元素分析、热稳定性和傅里叶变换红外光谱结果相似，这表明它们的物理化学结构总体相似。
