摘要: 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 (C-p) ranging from -60 to 90 degrees C (except the obvious phase change region from -20 to 20 degrees C). The content of bound water (W-b), immobilized water (W-i), and free water (W-f) were weighted and calculated. According to non-linear fitting of experimental data, the obtained empirical equation of C-p, temperature (T), W-b, W-i, and W-f of samples was:C-p = (a + bw(b) + cw(i)+ dw(f) + eT)/(1 + fw(b) + gw(i) + w(f)). The equation was in good correlation (R-2 > 0.95) with the experiment data and could provide a basis for improvement of processing parameters.
