Summary

Different measurement methods have been applied to study Granny Smith apple texture during shelf-life. The destructive and non-destructive indicators correlated well. Of the non-destructive methods, the acoustic impulse technique seems superior to the random vibration test because of its efficiency and less variation. Apple mealy texture is associated with the high internal air space. Microscopy observations indicated that the mealiness of apple relates to the separation of cells rather than the extent of tissue rupture. Tensile and compression tests may not conclusively indicate the degree of mealiness but may possibly indicate if apple is mealy or not as the apple flesh strength falls below a certain level.
