Determination of the ammonia content of fish as an objective quality assessment method
In order to evaluate the possibilities of the determination of ammonia as an objective quality assessment method for fish and crustaceans a series of storage experiments was carried out on cod ( Gadus morhua L), redfish ( Sebastes marinus L), plaice ( Pleuronectes platessa L) , herring ( Clupea hare...
