Resumen
Quality changes induced in fresh papaya slices after cutting were evaluated using digital image analysis of colour and fractal metrics besides structural changes. Radial slices of papaya (65% and 85% ripe) were exposed to a controlled environment to simulate extreme conditions on a salad bar. Colour variation and mechanical-structural changes depended on surface dehydration, exposure time, and ripening stage. Relationship between fractal dimension, lacunarity, and time showed evidence of patterns associated with non-homogeneous colour changes related to structural variations. Fractal metrics had potential to reflect noticeable colour changes that would be useful for monitoring shelf stability of minimally processed papaya.
