Abstract

Channel catfish fillets with different microwave heating times were evaluated by differential scanning calorimetry and low-field nuclear magnetic resonance to build suitable modeling of apparent specific heat capacity (Cp) ranging from −60 to 90°C (except the obvious phase change region from −20 to 20°C). The content of bound water (Wb), immobilized water (Wi), and free water (Wf) were weighted and calculated. According to non-linear fitting of experimental data, the obtained empirical equation of Cp, temperature (T), Wb, Wi, and Wf of samples was: C p = a + b w b + c w i + d w f + eT / 1 + f w b + g w i + h w f $$ {C}_{\mathrm{p}}=\left(a+b{w}_{\mathrm{b}}+c{w}_{\mathrm{i}}+d{w}_{\mathrm{f}}+ eT\right)/\left(1+f{w}_{\mathrm{b}}+g{w}_{\mathrm{i}}+h{w}_{\mathrm{f}}\right) $$ . The equation was in good correlation (R2 > 0.95) with the experiment data and could provide a basis for improvement of processing parameters.
