DETERMINATION OF SHRINKAGE AND SHAPE CHANGE OF APPLE SLICES DURING DRYING

One of the most important factors for customers choosing to buy is food appearance.Thus, Shrinkage plays an important role in determining the quality of the dried products.This paper presents a method based on computer vision to determine shrinkage and shape changes of apple slices during drying.The computer vision system consisted of a digital camera, illumination chamber, computer hardware and software was developed to capture and process the images.The drying experiments were carried out at 50, 60, 70 and 80 ° C and at the air velocities of 1, 1.5 and 2 m/s for constant sample thickness of 4 mm at a thin layer dryer.Variations in area, perimeter, major and minor diameters and diameters parallel and perpendicular to airflow were measured in intervals one minute during drying.Shrinkage variations showed a linear behavior with the moisture content changes at the examined conditions.Image analysis was successfully applicable to measure shape change of apple during drying.
