摘要

In the literature, in general, the kinetics of bioactive compounds extraction from a solid–liquid system is described by diffusion models and by the Peleg model. In this study, four experiments on the kinetics of anthocyanin extraction from jambolan fruit, at different agitation frequencies of the medium (0, 50, 100, and 150?rpm), are described by various empirical models with up to two fit parameters. According to the statistical indicators, the best model to describe the kinetic processes was Page's, which was also used to determine the extraction rates (all decreasing) and estimate the process times for each agitation frequency. The extraction time for the 150?rpm frequency is approximately six times shorter than that for 0?rpm. Thus, the 150?rpm frequency can be recommended for industrial applications, as the process time is an important variable in the production cost.
