The optimal conditions
determined by Derringer’s desired function methodology were as
follows: microwave power of 422 W, irradiation time of 169 s, pH of
1.4 and solid–liquid ratio of 1:16.9 g/ml with maximum pectin yield
(19.24%). Under the optimal conditions, the experimental values
(19.19 ± 0.07%) agreed with the predicted values (19.24%).
