Objective:
The objective of this research was to study the electrical properties and quality of frozen-thawed chicken breast meat and to investigate the relationship between these parameters at different times of frozen storage.
Methods:
Thawed samples of chicken breast muscles were evaluated after being kept in frozen storage at -18°C for different periods of time (1, 2, 3, 4, 5, 6, 7, and 8 months).
Results:
The results showed that water-holding capacity (WHC) and protein solubility decreased while thiobarbituric acid-reactive substances content increased with increasing storage time. The impedance module of samples decreased during 8-month frozen storage. Pearson correlation coefficients showed that the impedance change ratio (Q value) was significantly (p<0.05) related to pH, color, WHC, lipid oxidation and protein solubility, indicating a good relationship between the electrical properties and qualities of frozen-thawed chicken breast meat.
Conclusion:
Impedance measurement has a potential to assess the quality of frozen chicken meat combining with quality indices.
