In this study, papaya (Carica papaya) peel was dried using convection oven and microwave
drying methods to investigate the drying kinetics and the drying behavior in the attempt
to search for a feasible way to utilize waste peel. Three different drying temperatures
(45, 55, and 65 oC) and microwave powers (250, 440, and 600 W) were applied to dry
the papaya peel, wherein the drying data were fitted into the following seven drying
kinetic models: Lewis, Page, Modified
Page, Henderson and Pabis, Logarithmic,
Two-Term, and Approximation of Diffusion
models. The study outcomes indicated that
the Page model emerged as the best fitted
model for oven drying of papaya peels with
the highest coefficient of determination
(R2) value (0.994-0.996) for all the three
temperatures. As for microwave drying,
the Approximation of Diffusion model
exhibited the best fit owing to the highest
R2 value (0.996-0.999) for all the three
powers. The effective moisture diffusivity
