Physicochemical properties and sensory characteristics of sausage formulated with surimi powder.

The objectives of this study were to determine the physicochemical properties and sensory characteristics of fish sausage made with 100 % threadfin bream (Nemipterus japonicus) surimi powder (SP100), a mix of 50 % surimi powder and 50 % frozen surimi (SP50), and a control (100 % frozen surimi). No significant differences in protein content and folding test results (P > 0.05) were detected among the SP100 and SP50 samples and the control. Gel strength of SP100 was lower (P > 0.05) than that of the control. The texture profile analysis (TPA) values (hardness, cohesiveness, springiness, and chewiness) of SP100 were significantly lower (P < 0.05) than those of the control. However, the TPA values of SP100 and SP50 were still within the textural range of Malaysian commercial fish sausages. The water holding capacity, and emulsion stability of SP100 were significantly lower (P < 0.05) than those of SP50 and the control. Of the cooking properties measured, SP100 had lower (P < 0.05) cooking yield, moisture retention, and fat retention than the control. Quantitative descriptive analysis (QDA) performed by 12 trained panelists showed that sensory characteristic (hardness, cohesiveness, springiness, and chewiness) scores of SP100 were lower than those of SP50 and the control. The use of surimi powder in fish sausage did not differ with that of control in the term of color, odor, or oiliness scored by panelists. The drying process impacted the texture properties of surimi when it was used in fish sausage. However, the use of surimi powder in fish sausage formulation is still accepted since the TPA values of SP100 and SP50 were still within the textural range of Malaysian commercial fish sausages.
