摘要
目的:研究苦杏仁和燀苦杏仁的吸湿行为,探讨苦杏仁和燀苦杏仁吸湿能力差异的原因。方法:运用静态称重法测定并绘制苦杏仁和燀苦杏仁吸湿动力学曲线和吸湿等温线,用多种吸湿模型进行拟合并评价,筛选最佳拟合模型。通过组织结构特点、种子生命力检测和低场核磁共振成像技术(LF-MRI)分析苦杏仁和燀苦杏仁吸湿特性。结果:一级模型和Peleg模型可以较好地拟合苦杏仁和燀苦杏仁的吸湿等温线和吸湿动力学曲线,苦杏仁的吸湿能力高于燀苦杏仁的吸湿能力。组织结构分析和LF-MRI结果表明,苦杏仁种皮的存在导致苦杏仁和燀苦杏仁吸湿行为不同。结论:苦杏仁和燀苦杏仁吸湿行为的研究可为苦杏仁和燀苦杏仁的贮存条件和干燥工艺的选择提供实验依据。
Objective:To study the hygroscopic behavior of Armeniacae Semen Amarum and scalded Armeniacae Semen Amarum,to explore the reason of difference of moisture absorption capacity between Armeniacae Semen Amarum and scalded Armeniacae Semen Amarum.Methods:The static weighing method was used to measure and draw the hygroscopic kinetic curve and hygroscopic isotherm of Armeniacae Semen Amarum and scalded Armeniacae Semen Amarum,a variety of hygroscopic models were used for fitting and combining evaluation to screen the best fitting model.The moisture absorption characteristics of Armeniacae Semen Amarum and scalded Armeniacae Semen Amarum were analyzed by the characteristics of organizational structure,seed vitality detection and low-field magnetic resonance imaging(LF-MRI).Results:The first-level model and Peleg model could better fit the hygroscopic isotherm and hygroscopic kinetic curve of Armeniacae Semen Amarum and scalded Armeniacae Semen Amarum,the moisture absorption capacity of Armeniacae Semen Amarum was higher than that of scalded Armeniacae Semen Amarum.Microstructure analysis and LF-MRI results showed that the existence of seed coat of Armeniacae Semen Amarum led to the difference of moisture absorption behavior between Armeniacae Semen Amarum and scalded Armeniacae Semen Amarum.Conclusion:The study of moisture absorption behavior of Armeniacae Semen Amarum and scalded Armeniacae Semen Amarum can provide experimental basis for the selection of storage conditions and drying process of Armeniacae Semen Amarum and scalded Armeniacae Semen Amarum.
