Influence of osmotic pre-treatment on convective drying of yellow pitahaya

Cylinders of pitahayas were osmotically dehydrated in sucrose 55 % (w/w) during 45 minutes as a pretreatment of convective drying. Hot air drying was performed at 50, 60 and 70ºC. Drying kinetics of osmodehydrated samples was compared to untreated samples. Effective moisture diffusion coefficients w...
