Drying Kinetics and Total Phenolic Content of Dried Mentha arvensis Linn Leaves

The objective of this study is to investigate the effects of sun drying and infrared drying on drying characteristics and total phenolic contents (TPC) of MA leaves. Infrared drying temperature was ranged from 50⁰C to 80⁰C; average temperature of natural sun drying and enhanced sun drying was 34 ± 1.2⁰C and 45.67 ± 0.5⁰C respectively. To represent the experimental data, five different empirical models (Lewis, Page, Henderson & Pabis, Two-term Exponential and Midilli et. al) were used. The best model was selected based on highest R 2 , lowest RMSE and�� . TPC of dried leaves was determined and it was found that enhanced sun drying method gave the highest TPC.
