中文摘要：通过分析真空包装罗非鱼肌肉的质构、颜色、水分指标等物性特征与感官评价和微生物生长的相互关系,探讨物性参数用于评价鱼肉新鲜度的可行性。结果表明,随着贮藏时间的延长,罗非鱼新鲜度不断下降,感官指压弹性和颜色分值逐渐下降,耐冷菌和肠杆菌呈指数增长;水分相关指标与新鲜度没有明显关联;仪器法测定的硬度和a*值呈下降趋势,与感官评价的指压弹性和颜色分值具有良好的线性关系。

外文摘要：The relationship between the physical properties including texture, color, moisture related indicators, sensory quality and microbial growth were investigated to explore the feasibility of fish freshness evaluation by physical parameters. The results showed that, with the extension of storage time, fish freshness declined with the descending of the scores of finger-pressure elasticity and color in sensory evaluation, and exponential growth of psychrotrophs and enterobacteriaeeae. Moisture related indicators showed no obvious correlation with fish freshness. The hardness and a＊ value which were measured by instruments showed decreasing trend and good linear relationship with the scores of finger-pressure elasticity and color index in sensory evaluation.
