Abstract
The effect of blanching and/or glucose impregnation at atmospheric pre ssure or in vaccum on the kinetics of moisture transfer during the fir st falling rate period of air drying of apple was analyzed. The moistu re diffusivity of water (Deff) was strongly decreased by glucose uptak e during impregnation step as well as volume shrinking Studies of the cell structure rising transmission electron microscopy revealed that b oth pretreatments did not modify in a great extension rite cell wall r esistance to water flux.
