Objective To deeply analyze the sensory quality of flavor during the ripening process of red cheese through various methods for measuring food flavor quality. Methods The volatile flavor compounds and sensory quality of red cheese at different ripening periods were analyzed by solid phase microextraction arrow-gas chromatography-mass spectrometry (SPME arrow-GC-MS), electronic nose, electronic tongue, and quantitative descriptive analysis (QDA). Results The results showed that there were differences in the flavor profiles of red cheeses at different ripening periods. A total of 85 kinds of volatile flavor compounds were identified in red cheese by GC-MS. The total content of acids, alcohols, aldehydes, and ketones first increased and then decreased, while the total content of esters continued to increase. Combined with the relative odor activity value (ROAV) analysis, 28 kinds of characteristic volatile flavor compounds were identified. QDA yielded that yogurt flavor, wine flavor, and sour flavor would enhance significantly (P<0.05) during cheese ripening. In addition, electronic tongue analysis demonstrated significant differences in sourness and bitter aftertaste among red cheeses at different ripening periods (P<0.05). Conclusion This study analyzes and compares the sensory quality of flavor during the ripening process of red cheese from multiple perspectives by combining various methods for measuring food flavor quality. This study not only improves the understanding of the sensory qualities of red cheese but also provides a reference for the development, quality control, and flavor improvement of novel fermented dairy products.
