Effect of Methodology on Total Volatile Basic Nitrogen (TVB‐N) Determination as an Index of Quality of Fresh Atlantic Cod ( Gadus morhua)
ABSTRACT Six different published methods of determining TVB‐N were evaluated for accuracy, precision, suitability as an index of quality, and both cost and speed of determination, using gutted Atlantic cod stored in ice for up to 18 days. Although the method of determination affected the actual valu...
