The total carotenoids content was 3.28 and 5.17 mg/100 g db in
IRD and FD samples, respectively (Fig. 1c). Drying showed a significant
effect of heat on total carotenoids with the highest levels in
lyophilized samples (p 0.05). Ndawula et al. (2004) reported bcarotene
contents of mango to be 5.9 mg/100 g db, which were
degraded on drying to 0.34e1.58 mg/100 g db level. The carotenoids
content values were within the range of previously reported
and supported the declining trends in values with driers operating
at higher temperature.
