During the frozen storage period, a gradual hardening effect was observed in the control treatment (P.05). The effects of storage time on other textural parameters were small (P [ 0.05). The hardening effect of frozen storage has been mainly attributed to the chemical and structural changes in myofibrillar protein during storage, which results in the toughening of fish fingers (Lopez- Lopez et al. 2010). Due to the moisture retention ability of fibers, there were no changes in the hardness of Tsw and Tsp during this period (P [ 0.05). Moreover, Maqsood et al. (2012) pointed to the protective effect of antioxidants on the structural properties of final product through maintaining the integrity of muscle fibers and reducing the moisture loss.
