Resumen:
A hipothetical simplified description of the dynamic of ionic charge changes and unwinding of pectinic structure during the debittering process of green olives has been proposed. The change in the concentration of sodium and calcium ions during the debittering process was quantified in the olives flesh and in the lye by cuantification of Na and Ca. Also was evaluated the firmess of the olives during the process and reducing sugars were measure too. Finally the effective diffusion coeficients were calculated for sodium and calcium using a diffusion model for a composite flat plate and constant diffusion coefficients.
