2000; Ali et al., 2007, 2008), very few studies have evaluated
the meat quality and processing quality of duck
breast muscle that has undergone thaw-rigor.
The degree of thaw-rigor is greatly affected by thawing
temperature, and previous studies have evaluated
the quality characteristics of thaw-rigor muscle using
different thawing temperatures. The tested thawing
temperatures were 0 and 18°C on chicken muscles and
−2, 2, and 18°C on beef muscles (Yu et al., 2005; Lee et
al., 2007). Although the thawing temperature between
14 and 19°C did not affect the decrease in muscle shortening,
until recently, there has been very little research
to evaluate the effect of thawing temperature on meat
quality of the duck breast frozen prerigor as well as the
physicochemical properties of thaw-rigor duck breast
muscle.
Therefore, the objectives of this study were (1) to
evaluate the physicochemical properties of thaw-rigor
duck breast muscle thawed at 4 and 15°C and (2) to
evaluate the physicochemical properties of homogenates
prepared with the thaw-rigor muscle.
