摘要
The bacterial kinetics and quality indexes [sensory quality, total volatile basic nitrogen (TVB-N), thiobarbituric acid value, biogenic amine, and amino acids] were analyzed on salmon inoculated with Pseudomonas fluorescens during storage under different temperatures (30, 10, and 4 A degrees C). The bacterial kinetics revealed that P. fluorescens showed a steady growth at low temperatures (10 and 4 A degrees C). The TVB-N yield factors of the sample stored at 4 A degrees C indicated that each bacterial cell of P. fluorescens displayed greater spoilage activity at low temperatures. A remarkable correlation was found between the production of biogenic amines and bacterial counts. The results also highlighted that P. fluorescens cultured at 4 A degrees C had higher demand for amino acids.
