Abstract:

The effect of blanching and glucose concentration before drying on the rate of moisture movement during the early stages of air dehydration of strawberries at 55 °C was studied. It was found that the effective diffusion coefficient of water in strawberries (D eff ) was strongly affected by heat pretreatment, but glucose dipping after blanching caused no additional effect. Electron microscopic studies of strawberry tissues were used to explain this behavior through a modification of cellular structure, disruption of cell membranes of heat-treated fruit and subsequent cell wall alteration during the osmosis step. © 1995.
