摘　　要：红枣在自然干燥下的含水率下与其弹性模量有一定关系,以新疆阿克苏灰枣和骏枣为原材料,利用压力实验机和水分测定仪,研究在自然干燥下在不同含水率情况下压力值和弹性模量之间变化规律,建立含水率与弹性模量的数学模型,对灰枣和骏枣进行对比实验。实验结果表明:自然干燥下的红枣的含水率与弹性模量呈现出线性变化关系,即随干枣的含水率增大,弹性模量减少,不同品种的干枣在含水率相近的条件下,弹性模量不同,骏枣的弹性模量大于灰枣的弹性模量。There is a certain relationship between the moisture and the elastic modulus of the Jujube under the natural drying by the gray Jujube and Jun Jujube of Xinjiang Aksu as the raw material. Using pressure testing machine and moisture analyzer, the change regulation between pressure value and the elastic modulus was researched in different moisture under the natural drying, and the mathematical model was established. The results show that the moisture, content and the elastic modulus of the jujube showing a linear variation under natural drying. Along with the increase the moisture content of dried Jujube, elastic modulus decrease. The elastic modulus of varieties dried Jujubes is different under the similar condition of moisture content. The elastic modulus of Jun Jujube is greater than gray jujube.
