Article history:
\n<\/em><\/strong>Received: January 20, 2020
\nAccepted: April 3, 2020<\/td>\n		Nonlinear regression analysis was conducted for thin layer drying characteristics of two onion varieties (white and red) and some quality characteristics were also examined. The experimental data obtained at drying temperatures of 40, 50, and 60 o<\/sup>C and thicknesses of 2, 4 and 6 mm, was subsequently fitted into four commonly used models (Henderson and Pabis, Lewis, Page, and logarithmic). Moisture diffusivity and activation energy ranged from 8.9 \u00d7 10-10 <\/sup>to 8.4 \u00d7 10-9 <\/sup>m2<\/sup>\/s and 55.98 to 65.68 KJ\/mol, respectively. Significant differences (p<\/em><0.05) were observed in the colour profile and rehydration ratio. The optimum desirable colour was obtained at
\n50 o<\/sup>C with 2 mm thick onion slices and the observed higher rehydration ratio indicates good quality of dried onions. Among the four selected drying models, the Page model predicted optimally (R2<\/sup> > 0.9) and was found to be better in describing dried onion varieties, while the Lewis model provided the least fit.<\/td>\n<\/tr>\n
