Abstract

This study investigated microstructural changes in broad bean seeds at 0 and 8 °C at a vacuum degree of 97 kPa using an SEM. The cellular-morphology distributions changed obviously with time and temperatures. Although cell rupture occurred, higher temperatures caused more cells to contract more actively. The cell size was primarily affected by moisture content, while the cell shape was simultaneously influenced by temperature and moisture content. The diameter correlated well with moisture loss and shrinkage during dehydration (correlation coefficients > 0.96). However, the correlation was not strong (most correlation coefficients < 0.9) when the cell shape was considered.

摘要

本研究使用 SEM 研究了蚕豆种子在 0°C 和 8°C、真空度为 97 kPa 的情况下的微观结构变化。细胞形态分布随时间和温度变化明显。尽管发生了细胞破裂，但更高的温度会导致更多细胞更积极地收缩。细胞大小主要受水分含量的影响，而细胞形状同时受温度和水分含量的影响。直径与脱水过程中的水分损失和收缩密切相关（相关系数 > 0.96）。然而，当考虑细胞形状时，相关性不强（大多数相关系数 < 0.9）。
