A high oil content in fried banana chips shortens the shelf life of the product and causes a decrease in
product acceptability to consumers. The oil absorption problem associated with fried products might
be reduced by using hydrocolloids as edible coatings and modifying the frying process during the oil centrifuge
step of vacuum frying. The objective of this study was to determine the effect of edible coating
materials and the speed of the oil centrifuge step on the amount of oil absorption and the physical properties
of vacuum-fried banana chips. Compared with regular vacuum-fried products (control samples),
banana chips coated with either guar gum or xanthan gum solutions at 1.5% or centrifuged at a higher
speed than standard conditions (from 140 to 280 rpm) reduced oil absorption by 25.22%, 17.22% and
17.31%, respectively. Moreover, the combination of an edible coating and the higher centrifugation speed
resulted in a greater reduction of oil absorption (33.71%) compared with control samples. Therefore,
banana chips coated with an edible coating and produced using the higher speed during the oil centrifuge
step in the vacuum-frying process maintained a good quality with low oil content, representing a healthier
snack for consumers.
