COLORIMETRIC IMAGE ANALYSIS AS A FACTOR IN ASSESSING THE QUALITY OF PORK HAM SLICES DURING STORAGE AN´ ALISIS COLORIM´ ETRICO DE IM´ AGENES COMO FACTOR DE EVALUACI ´ ON DE LA CALIDAD DE REBANADAS DE JAM ´ ON DE CERDO DURANTE ALMACENAMIENTO

This study analysed the colour changes of stored pork ham slices at two temperatures (4 and 8°C) to compare two imaging methodologies for estimating colour changes over time in CIELAB colour spaces through a DigiEyefi and stereoscope with digital image analysis. Colour space changes were analysed using a computer vision system for image segmentation analysis. It was determined that from the ninth day, changes could be perceived in the representative colour of ham slices using DigiEyefi. Finally, colour prediction equations with R 2 >0.85 were determined as a tool for electronic monitoring
