该数据集呈现了由虾废料制备的不同γ（γ）辐照前后（10 kGy和20 kGy）的壳聚糖的形态特征、元素组成和官能团。利用傅里叶变换红外光谱（FTIR）和X射线衍射（XRD）对γ辐照壳聚糖进行了表征。使用Perkin Elmer Pyris Diamond DSC以10 °C/分钟的加热速率和设定为100 ml/分钟的流速的动态合成大气空气进行热重分析/差热分析（TG/DTA）。我们观察到，与未辐照的壳聚糖相比，经γ辐照的壳聚糖具有较短的聚合物尺寸、小孔和具有活性烷基和羟基的致密结构。我们的数据为虾壳聚糖暴露后的结构提供了基线理解，这意味着生物聚合物变得更加稳定，并被认为适用于广泛的食品工业应用。
This dataset presents morphological features, elemental composition and functional groups of different pre- and post-gamma (γ)-irradiated chitosan (10kGy & 20kGy) prepared from shrimp waste. The γ-irradiated chitosan was characterized using Fourier transfer infrared (FTIR) spectroscopy and X-ray diffraction (XRD) analyses. Thermogravimetry/differential thermal analysis (TG/DTA) were performed using Perkin Elmer Pyris Diamond DSC with a heating rate of 10 °C/minute and dynamic synthetic atmospheric air set at flow rate of 100 ml/minute. We observed γ-irradiated chitosan to have shorter polymer size, small pores and compacted structure with active alkyl and hydroxyl groups when compared to non-irradiated chitosan. Our data provides baseline understanding for structure of shrimp chitosan after60Co exposure which means, the biopolymer becomes more stable and is considered suitable for vast food industry applications.
