Study on the Prediction Model of Acidity in Apple Produced in Different Habitats

Abstract:

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.
