Fig. 3. Left panel: SDS-PAGE without or with dithiothreitol (DTT) of homogenates prepared from meat emulsions added transglutaminase (T), 100 (1), 500 (2), or 1500 (3) ppm green
tea extract (GT) and control meat emulsions without any addition (C) stored at 5 °C for 1 day. Staining was conducted with Sypro Ruby to detect proteins. Right panel: Pixel intensity
of non-reduced or reduced myosin heavy chain (MHC) without or with DTT, respectively. Letters (a–c) denote significant difference (P b 0.05) between MHC without DTT. Letters (w–
z) denote significant difference (P b 0.05) between MHC with DTT.
