KINETIC OF COLOUR CHANGE OF AIR DRIED FORTIFIED APPLES WITH VITAMIN E

The kinetics of color changes in dehydrated apples fortified with vitamin E is evaluated starting from the CIE-L*a*b * coordinates, tone (hab*) and chromes (Cab*), during 180 days and storage temperatures of 4, 20 and 30ºC. Due to translucency of samples, the Kubelka–Munk’s theory of multiple light...
