Mechanical Properties of Apple Essentail in Respect to Damage

Apple is produced in one of the lergest volume of fruits in Hungary. The damage determinated mechanical properties are situated in sygnificant point amout all quality features. If we know them, we can design the different process (eg. Transport, packing, post harvest technologies). The solving of impact problem (Boussinesq) with a good rheological model (Poyntig-Thomson) is the base of our theoretical method. We expanded our results to investigation of transported apples (eg. in big box). The main results are: 1) The mechanical situation of apples can be characterized with a good described area. 2) The features of damage aren’t like points, but like an area. 3) We have given the firmness of Hungarian varieties depending of this one on the place of fruit surface, changing of the firmness depending on growing and storage temperature. 4) We give a model for determining the bruise of apple transported in crate in different circumstances. Our method can be used with different fruits which are similar to apple.
