Porównanie wyników instrumentalnej i sensorycznej analizy tekstury wybranych gatunków serów

Abstract

For comparison of results of sensory and instrumental analysis, six kinds of fatty cheeses, of different hardness were subjected. Instrumental tests were carried out by the device in which viscoelastic materials were subjected to dynamic sinusoidal deformations (imitating the chewing process), letting for receiving stress as the relation of the time or the deformation. Statistical analysis of outcomes of the sensory assessment and results of the instrumental assessment showed a strong correlation between these results in case of measurements of the hardness (r = 0.84), springinesses (r = 0.75), guminess (r = 0.80) and chewiness (r = 0.84). The comparison between results of the sensory evaluation and instrumental assessment with use of the analysis of main components showed the strong positive correlation between hardness, springness and gumminess, and chewability, weaker positive correlation related to results of adhesiveness and cohesiveness.
