Many studies that propose to investigate retention of carotenoids
in processed foods do not take into account the gain or loss of weight
during processing through incorporation or through loss of water or
water soluble solids. This could cause either underestimation or
overestimation of the true retention value. A simple calculation on
dry basis may also overestimate the retention of these compounds
(De Sá & Rodriguez-Amaya, 2004; Rodriguez-Amaya, 1999).
