Gelatinization of wheat flour without or with black tea infusion was analyzed by a differential scanning calorimeter (DSC, Q100) equipped with a thermal analysis data station (TA Instruments, Newcastle, DE, USA). Wheat flour (2 mg) and 4 μL of water or tea mixture were added into aluminum pan. Pans were sealed and stood for 1 h at room temperature. The scanning temperature range and heating rate were 25–135 °C and 10 °C/min, respectively. An empty aluminum pan was used as reference. Onset (To), peak (Tp), and conclusion (Tc) temperatures, and enthalpy change (ΔH) of gelatinization were recorded.
