The kinetics of a batch solid–liquid extraction of total phenolic compounds from milled grape seed using 50% ethanol at temperatures (25–80 C) was studied. A new model includig the concept of broken and intact cells and a linear equilibrium at the solid–liquid interface was developed. Both equilibrium partition coefficient and effective diffusion coefficient were temperature-dependent.
