Modified maize and cassava starch solutions were prepared accord-ing to the manufacturer’s instructions: heating the cassava starch
suspension (1.5g/100 g of water) at 95C for 10 min;
and heating the maize starch suspension (2.5 g/100 g of water) at 90C for 2 min.
In order to evaluate the effects of the starch and of the appli-cation temperature of the edible coating on the carotenoid content
of slices of dried pumpkin, native starch coating and modified corn and cassava coating were applied at the gelatinization temperature
(80-90C) and in the previously cooled solution (30C).
The slices were soaked in the starch solutions for 1 min, pre-dried through draining,
on perforated stainless steel trays at room temperature for 50 min in the dark.
They were turned over at 25 min and dried in a forced air oven at 70C for a period of 8e10 h until moisture content of approximately 10 g/100 g.
