The results indicated that incorporation of both U. intestinalis powder and particularly USP produced fingers with softer texture compared with the control (P 0.05). According to Pinero et al. (2008), changes in the hardness of meat products as a function of texturemodifying ingredients’ addition may be associated with the water retention properties of the ingredients. Therefore, the softer texture of Tsp compared with the two other treat- ments (P 0.05) could be attributed to the higher moisture content of USP containing fingers (Fig. 1).Softer texture of the treated samples compared to that of the control significantly affected the chewiness and gum- miness of fish fingers (Tsw and Tsp) and reduced them (P 0.05). Cohesiveness, referred to as the strength of the internal bonds, showed no significant difference between Tsw and Tsp (P [ 0.05); however, it was decreased sig- nificantly in both treatments as compared to that of control sample (P 0.05). The addition of USP and U. intestinalis powder to the fish fingers produced less degree of springiness as compared to Tc; such decrease was more pronounced in the USP added fingers (P 0.05). The results of warner–bratzler shear force test were also in accordance with the TPA parameters. The harder was the texture, the more force was needed to shear the product. However, no significant difference was observed between Tc and Tsw in some textural characteristics within several months of storage (P [ 0.05).
