On the evaluation of textural qualities of fish paste products (heat induced gels), the relationships between the instrumental measurements (e. g. jelly strength and creep elements) and sensory evaluation were investigated using 4 species of fish. The sensory evaluations were done by using 12 descriptive 7-point rating scales.
An application of factor analysis showed the onomatopoeic features of sensory evaluation and the relationships between its sensory evaluation in the instrumental measurements as follows: (1) the characteristics of heat-induced gel were rheologically subdivided into three categories, viz. “hardness (stiffness)”, “elasticuess”, and viscousness"; (2) they corresponded to the distortional aspects of time in creep elements; and (3) both “hardness (stiffness)” and “viscousness” corresponded universally to jelly strength.
