| 摘 要： | 挥发性盐基氮(TVB-N)是反映水产品鲜度变化的重要指标之一。通过测定不同贮藏温度下的TVB-N随时间的变化值,并配合感官评价和汁液流失率的测定,研究其与生鲜水产品草鱼(Ctenopharyngodon idellus)腐败的相关关系,并建立TVB-N值与贮藏时间和贮藏温度之间的动力学模型。结果表明,挥发性盐基氮的值与贮藏温度及时间均呈正相关,即温度越高,时间越长,TVB-N值越大且增长趋势越明显,感官评分下降,汁液流失率上升,指标变化均反应水产品腐败程度加深。不同温度下TVB-N值随贮藏时间变化呈显著正相关(R20.987)。其一级反应动力学模型和阿伦尼乌斯方程对TVB-N值的变化有很高的模拟精度。挥发性盐基氮变化阿伦尼乌斯方程的回归系数为7.77×109。

Study on the Relationship Between TVB-N and Fresh Grass Carp Fillet Storage Time and Temperature |

| Abstract: | Total volatile basic nitrogen﹙TVB-N﹚ is one of the important indexes to evaluate the freshness of aquatic products. To study the relationship of TVB-N and fresh grass carp fillet spoilage, changes of TVB-N,sensory qualities and juice leak-age rate with time at different storage temperature were investigated by periodically determination. The kinetic model was es-tablished between TVB-N value and storage time and temperature. The results showed that TVB-N values were positively correlated with storage temperature and time,that is, the higher the temperature, the longer the time,TVB-N value will be higher and the growth trend is more obvious. Accompanied by a decline in sensory scores,drip loss rate was on the rise. In-dicators of changes response to the deepening of the degree of corruption of aquatic products. The TVB-N values were signif-icantly positively correlated with storage time in difference storage temperature ﹙R2>0.987﹚. The first order reaction kinetics model and the Arrhenius equation have very high simulation precision to the change of TVB-N values with time and temper-ature. The regression coefficient of Arrhenius equation in TVB-N change is 7.77×109. |
