Adsorption isotherms for red chilli (Capsicum annum L.)

The adsorption equilibrium moisture contents for red chilli were determined experimentally in relative humidity range of 11-97% at the temperatures of 20, 30, 40, and 50 degrees C. Six equilibrium moisture content models were fitted to the experimental data. The modified Oswin model was the best fitted equation for relative humidity range of 11-97% for the adsorption data of red chilli.
