چکیده انگلیسی
The relationship between the mixing state of wheat flour-water systems and the mechanical energy generated using a vertical mixer was revealed. To determine the mixing state, we measured the color changes in the systems using a color difference meter by adding caramel color regent as the indicator and measured the spin-spin relaxation time (T2) by a low-field 1H NMR technique. The mixing progress was calculated and presented in terms of an “action number”. As mixing progressed, the net energy increased and the net power also increased gradually, but after reaching its maximum value of 0.8Â kJ, it decreased. At the boundary of this inflection point, the state of the wheat flour-water mixture greatly changed. The relationship between the net energy and the color of the mixture, a turning point appeared at the net energy of 0.8Â kJ, and this behavior was consistent with the NMR T2 relaxation data.
