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.
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).
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.
Impedance measurement has a potential to assess the quality of frozen chicken meat combining with quality indices.
本研究的目的是研究冻融鸡胸肉的电特性和品质,并探讨在不同冷冻储存时间下这些参数之间的关系。
将鸡胸肌肉的解冻样品在-18°C下冷冻储存不同时间(1、2、3、4、5、6、7和8个月)后进行评估。
结果表明,随着储存时间的增加,持水能力(WHC)和蛋白质溶解度降低,而硫代巴比妥酸反应性物质含量增加。在8个月的冷冻储存期间,样品的阻抗模量降低。Pearson相关系数表明,阻抗变化率(Q值)与pH、颜色、WHC、脂质氧化和蛋白质溶解度显著相关(p<0.05),表明冻融鸡胸肉的电特性和品质之间存在良好的关系。
阻抗测量结合品质指标有潜力评估冷冻鸡肉的品质。
