Title

Drying kinetics of apples with pectin coatings

Abstract

In this work results considering convection drying kinetics under constant conditions of raw and osmodehydrated apples, coated or uncoated with pectins are presented. It was found that coatings based on low methyled pectin caused decrease of drying rate for the considered temperature range 50-90° regardless of presence or absence osmotic dehydration before drying. However coatings based on high methyled pectin had not the effect on drying kinetics of raw apples dried at 70°C and caused in a small degree increase of drying rate for osmodehydrated apples.
