摘要:

通过对速冻马铃薯条的感官评价和仪器测试(剪切、TPA压缩),分析感官评价项目与仪器测定指标的相关性,得到了感官评价项目的回归方程并建立了预测模型。然后通过样品的测定数据对预测模型进行验证,分析预测的平均误差在3.85%~5.98%之间,表明模型能较好的预测薯条的感官品质。

Abstract:

The aim of this study is to evaluate the practicability of evaluating sensory property through instrument method. Correlation analysis between sensory evaluation and instrumental measurement was conducted. Linear regression was used to establish a predictive model of sensory properties. The average errors of the regression equation were bebween 3.85% and 5.98%.
