Habanero pepper (Capsicum chinense) is a source of phytochemicals or bioactive compounds that have shown benefits in human health. For phytochemicals extraction process, a prior drying is required. Therefore, the aim of this study was to evaluate the effect of drying temperature (30, 50 and 70 degrees C) on total capsaicinoids and total carotenoids, and the coefficients of water diffusivity during drying of sliced red habanero pepper. The results show that the bioactive compounds, present a major stability at high temperature (70 degrees C), the effective diffusivity increased with drying temperature and the activation energy of the process was calculated to 39.575 kJ mol(-1) K-1. Several theoretical aspects of average water diffusivity are discussed.
