Direct determination of the thiobarbituric acid value in trichloracetic acid extracts of fish as a measure of oxidative rancidity
The possibilities of the direct determination of the thiobarbituric acid (TBA) value in trichloracetic acid (TCA) extracts instead of distillates were evaluated. Tests carried out on herring ( Clupea harengus L.), redfish ( Sebastes marinus L.), cod ( Gadus morhua L.), plaice ( Pleuronectes platessa...
