What the research is about
This study aimed to evaluate the freshness of ice stored rainbow trout by bioelectrcal impedance measurements. Rigor mortis, ATP-related (adenosine triphosphate) components, K-value, and hardness of rainbow trout muscle during storage were monitored along with impedance.
Research conclusion
Impedance measurement has a great potential for predicting the freshness of the rainbow trout during ice storage.
Assurant Innovations take
Bioelectrical impedance measurement with the Fish Analyzer is a great way to measure fish freshness. It had a strong correlation with the K-value as this is a standard accepted to measure fish freshness. It’s quick, non destructive and portability to give accurate results anytime/anywhere is a great tool to have to determine fish freshness.
