ABSTRACT

Texture changes of canned shrimp were determined by sensory and instrumental methods. A direct relationship was found between sensory perception of toughness and instrumental shear forces measurements in canned shrimp packed in 2.6% brine in 307×113 cans, and processed at 124°C. Shrimp muscle toughened during the initial stages of heating and softened during the latter stages of processing. The softening of shrimp texture (shear values) was determined to follow apparent first order behavior. Regression analyses were used to establish apparent reaction rate constants, an apparent activation energy (24 Kcal/mole), textural D values and textural Z values (30°C).
