摘　　要：以石榴种子的含湿量作为主要因素,研究石榴种子的尺寸、内部孔隙率、硬度、坚实度等物理参数。干石榴种子的依赖于水分含量的物理性能的含水量范围定义为5.73-25.31%(湿基)。结果:算术平均直径:4.17-4.20mm,几何平均直径:3.56-3.77mm,硬度:47.28-82.11N,坚实度:16.96-35.64N·mm,内部孔隙率9.08-19.17%。结合水相对含量及运动特性随总体水分含量的减少而总体呈减少趋势。The purpose of this study was to determine the physical properties of dry pomegranate seeds depends on the water,as a function of the water content,for follow-up studies preparation method of supercritical extraction pomegranate seed oil.in this study,depends on the moisture content of dry pomegranate seed moisture content scope is defined as the physical properties of the 5.73-25.31%（wet basis）.Arithmetic average diameter：4.17-4.20 mm,geometric average diameter：3.56-3.77 mm,hardness：47.28-82.11 N,firmness：16.96-35.64N·mm,internal porosity：9.08-19.17%.Bound water relative content and movement characteristics decreased with the decrease of total water content.
