凝胶软糖质构特性的感官评定与仪器分析研究

针对目前广州市场上不同品牌的凝胶软糖的质地特性进行感官评定与仪器分析的相关性研究。选用9种市售凝胶软糖,采用质地剖面检验法进行感官评定,质构仪(TPA模式)进行仪器分析,对感官评定与质构仪测定结果进行相关性分析。研究表明,凝胶软糖的仪器分析能很好地反映感官质构,其中质构仪测定出的硬度、弹性、咀嚼性与对应的感官指标有显著的相关性。选取主要仪器分析指标为自变量,感官评定指标为因变量,进行逐步回归分析,得到具有统计意义的感官硬度和感官弹性的预测方程。表明TPA质构分析和感官质构评价均能较准确地测定和反映目前市售凝胶软糖的质构。为利用质构仪测定定量表达凝胶软糖的感官质构提供理论依据。

Study on Sensory Evaluation and Instrumental Measurement of Texture Characteristics of Gel Candies

The correlations of sensory evaluation and instrumental measurement for the different commercially available gel candies in current Guangzhou market were studied in this paper.Nine common commercial gel candies were collected.Texture profile analysis with twelve trained panelists was used to evaluate the sensory characteristics of samples and TPA(texture profile analysis) was used as instrumental method.The results showed that there are correlations between the TPA experiment parameters,included hardness,sp...
