摘要: 以熟肉为研究对象,比较感官评定和两种仪器测定方法(剪切法和质构剖面分析)之间的差异和关联性。结果表明:剪切力与感官评定的硬度、多汁性呈显著相关性(r=0.73、-0.71);质构剖面分析硬度与感官评定的硬度相关性显著(r=0.81),质构剖面分析的粘聚性与感官评定的弹性、多汁性、油性分别呈显著相关性(r=-0.79、-0.67、-0.81)。通过建立仪器分析与感官评定间的数学模型,本实验提示质构剖面分析更能全面预测猪肉感官品质。进一步的实验参数验证了质构剖面分析回归方程预测的准确性。

Abstract: Pork texture was assessed by two instruments determination(shear method and texture profile analysis,TPA)and also by sensory evaluation on cooked meat.Shear force is significantly(p<0.05)correlated with sensory hardness and juiciness (r=0.73,-0.71,respectively).The hardness of TPA is significantly(p<0.05)correlated with sensory hardness(r=0.81)and the cohesiveness of TPA significantly(p<0.05)correlated with sensory springiness,juiciness, and greasiness(r=-0.79,-0.67, -0.81,respectively).Stepwise regressions between instruments and sensory evaluation are obtained,and the better model belongs to TPA parameters for prediction of sensory characteristics.Also,TPA prediction models are verified.
