Effects of Ozone Treatments on the Physicochemical Changes of Myofibrillar Proteins from Silver Carp (Hypophthalmichthys molitrix) during Frozen Storage

Figure 4

Change in protein patterns of silver carp surimi during frozen storage. Tc: two washing cycles using ice water only; To1: first and second washing cycle using ice water containing 8 mg/L ozone and ice water, respectively; To2: first and second washing cycle using ice water and ice water containing 8 mg/L ozone, respectively. (a) Protein sample was dissolved in loading buffer without β-mercaptoethanol; (b) protein sample was dissolved in loading buffer with β-mercaptoethanol; STD: kaleidoscope protein standard; MHCXL: cross-links of myosin heavy chain; MHC: myosin heavy chain; AC: actin; TM: tropomyosin; TN T: troponin-T; MLC 1: myosin light chain 1.
