The
changes of textural properties (Hardness, adhesiveness, springiness,
cohesiveness, gumminess, chewiness and resilience) and shear force ofEsox
luciusunder different refrigeration temperature (4?℃and 0?℃) were measured by Texture Profile Analysis (TPA) model and the
Warner-Brazler of texture analyzer, meanwhile, changes of pH value,
electroconductivity and water-holding capacity were studied. The results
obtained from this study reveal that pH value of theEsox luciusmuscle
showed a downward trend in earlier stages of storage and then showed a upward
trend with the storage time increased, while electroconductivity and
adhesiveness generally showed a upward trend during the whole storage period,
and the two indicators ofEsox luciusmuscle
stored
at 0?℃ were less than that stored at 4?℃, what’s more,
water-holding capacity, hardness, springiness, cohesiveness, gumminess,
chewiness, resilience and shear force of the samples showed a declining trend
at vary degrees, and these indicators under 0?℃ were significantly higher than those under 4?℃.
