Efecto de un pretratamiento químico en el deshidratado del arándano por métodos combinados

Abstract

The objective of this paper was to study the chemical removal of blueberry skin at different soda concentrations and immersion times. In methodology, a surface response factorial design of type 22 was considered. As a response, blueberry skin removal was considered, either total or partial. The variables analyzed were soda concentration and immersion time. Results indicated that soda concentration had a marked positive effect, as did immersion time although to a lesser extent. Both variables should not be interpreted separately, given the considerable effect produced by their interaction. It can be concluded that adequate skin removal was achieved by using 1.5% NaOH for 5 seconds, without damaging the fruits.
