Relationship between pH values and electrical conductivity, their usability in chicken breast meat evaluation as marker post mortal quality

Popis výsledku v původním jazyce

The meat quality parameters measured in carcass production at slaughterhouses tend to be essential for the control of its overall quality. In this experiment, two different groups of poultry, commercial broilers Ross 308 (n=24) and Lohmann Brown-Classic hens (n=24) in 3 independent batches (A, B, C) were used for pH and electric conductivity (EC) measurement at different times (45 and 180 minutes) after slaughter. Experiment was based on monitoring the dependence and applicability of pH and electric conductivity methods. There was found statistical difference (P &lt; 0.05) between pH values and electrical conductivity between broilers and hens after slaughter. Differences were confirmed in both two times of measuring (45 and 180 min), which allows the use of both of them, without the risk of delay in control process of poultry in slaughterhouse. There was no statistical difference (P &gt; 0.05) between pH values and electrical conductivity between independent batches, this showed the independence of these markers on the selected external factor. The last hypothesis of the experiment, that there is no difference (P &gt; 0.05) between the first and second measurement of pH and electrical conductivity between groups and batches, was confirmed. Averagely strong negative relationship was determined between pH and EC in times 45 and 180 minutes, only in broiler group (r = -0.61*, -0.74). Correlation increased in time, so using of a later measurement time (180 minutes) for pH or electrical conductivity is possible, and even more advantageous.
