中文摘要:

为了研究不同产地苹果贮藏期内酸度变化情况并对酸度进行预测,采用了计算机断层扫描(CT)技术对苹果进行了无损检测,并通过二次拟合建立预测模型。试验结果探明了苹果贮藏期内酸度的变化情况,建立了不同产地苹果酸度和CT值的响应曲面模型以及综合的酸度预测模型。验证试验结果表明,预测模型的平均误差率为12.14%,模型表现出了良好的预测效果。

英文摘要:

In order to study the changes of the acidity in apple produced in different habitat during the storage time and predict the acidity,Computed tomography(CT) was used in the apple nondestructive testing,and a prediction model was also established by the quadratic fitting.The changes of apple during the storage time were proven by the results,what’s more a response surface model combining the acidity and the CT number and an acidity prediction model were established.The confirmation experiment indicates that the average error rate was12.14%,which shows a good adaptability and predicting effect.
