Abstract: It is necessary to establish a mathematical model for microwave enhanced extraction because the yield of natural pigment is affected by average microwave output power, microwave irradiation time, solvent amount, crushed degree of pomelo peel, and so on. In order to take all factors into account, a mathematical model which keeps in touch with experimental data has been established by “Dark-Box” method. Then the experimental data is further regressed by computer and the coefficients of nonlinear equation are obtained.

Key words: microwave, natural pigment, mathematical model
