Notes:
: Ammonia ion-selective electrode (ISE) measurements, reported as apparent ammonia, were correlated to expert sensory assessments of 6 different fish species stored on ice and at room temperature. Total volatile base nitrogen (TVB-N), trimethylamine nitrogen (TMA-N), and apparent ammonia showed the same development trend during storage. ISE measurements and TVB concentrations had a correlation of r2= 0.92. Sensory assessment, using a 1- to 100-mm line scale with values 〉 50 considered unacceptable, resulted in an r2between sensory scores and ISE measurements of 0.78. Regression analysis predicted 19.6 mg/100 g of apparent ammonia in fish tissue at the sensory limit of 50, regardless of storage conditions. ISE measurements could be used in predicting borderline quality and decomposition.
