Optimization process parameters of foam mat drying in totapuri mango pulp with foaming agent GMS

Mango is widely preferred because of its excellent flavour and nutritional quality. Mango pulp from Totapuri was extracted and then was subjected to foam mat drying along with 5, 7, and 9% GMS and later with egg white as foaming agents and then dried at temperatures of 60, 70 and 80°C. Weight loss was used to estimate change in moisture ratio with respect to time and effective diffusivity. Three thin layer drying models were fitted to get the best fit model, which was selected on the basis of various statistical parameters.
