Evaluation of Mechanical Bruise of Apple During Transport and Storage

The law and the method of evaluation of apple bruise during transport, storage and impact were studied by using the Multiple Regression and Rheological model parament analysis. In this study,the delay bruise caused by viscoelastic deformation and the possibility of using it to predict the bruise of apple were emphasized. The math. model of relationship between mechanical bruise and primary affecting factors were found. The correlations among evaluating indexs were also given.
