Abstract
ABSTRACT The present study provides the first data on the extraction kinetics of polyphenols from algerian Inula viscosa and aims to model the phenomenon of matter transfer involved. Different models have been applied and evaluated for different conditions of temperature, solid to liquid ratio and stirring speed. The operating conditions affect the kinetic parameters as well as the mass transfer properties. The diffusion coefficient values ranged from 2.25*10−12 to 31.44*10−12 m2.s−1. The Biot number vary from 45.37 to 92.35 which shows that internal mass transfer limits the extraction process. Activation energy (Ea) was found to be 25.22 KJ .mol−1.
