Hydrocolloid type and pre-fry drying had significant
effect (p < 0.05) on coating pick-up (Table 1). As
shown in Figure 1, xanthan gum had the highest
coating pick-up for both treatments. The presence
of hydrocolloids in the coating formulation enhance
coating pick-up because of their ability to impart
viscosity (Hsia et al., 1992). Generally, coated chips
that were not pre-dried had higher coating pick-ups
(16.68-36.38%) than the pre-dried samples (15.71-
35.08%). This could be due to wetter surface of the
former. This was apparent because generally wet
surfaces are needed for solid particles to adhere.
Moreover, the binding effect of hydrocolloid is
