Interactions of lipid and protein changes with bioelectrical measurements in frozen-stored hake and mackerel

In this study, we measured changes on several fish species during 5 months of frozen storage. The HP 4294A Precise LCR meter was used to measure impedance magnitude and phase at 200 frequencies from 100 Hz to 100 MHz. The protein solubility, TVBN and water holding capacity were determined. Unsaturated fatty acids and several aldehydes, alcohols and ketones were quantified. Results were statistically evaluated in SPSS with the aim of better understanding of the bioelectrical phenomena in fish tissues and determinig the best indicators of frozen storage deterioration.
