Outline
To establish a scientific and systematic methodology for evaluating the characteristic quality attributes of frozen fried dough sticks.
The 12 commercially available mainstream brands of frozen fried dough sticks were selected as the research subjects. The measurements of quality indicators including textural properties, chromaticity, flavor compounds and nutritional composition were conducted. The fuzzy binary comparison decision-making method was performed to identify key sensory evaluation indicators across 5 dimensions: visual, olfactory, auditory, gustatory and tactile perceptions. Key indicators were further screened and comprehensively evaluated through correlation analysis, principal component analysis and cluster analysis.
The total of 20 indicators that could be categorized into 6 principal components with a cumulative variance contribution rate of 91.217% were selected. The cluster analysis, taste, internal structure, brightness (L*), red green ratio index (a*), sodium chloride content, moisture content and fat content were identified as the core evaluation indicators for the quality of frozen fried dough sticks.
The quality evaluation system developed in this study enables an objective and quantitative assessment of the overall quality of frozen fried dough sticks. It not only provides guidance for consumer decision-making but also offers a precise scientific basis for optimizing formulations and advancing the industrial production of healthier, low-oil, and low-salt frozen fried dough sticks.
