This study aims to investigate the effects of various storage conditions on the flavor quality of citrus fruits and to integrate machine learning models for rapid, non-destructive detection. Raman spectroscopic analysis revealed significant variations in the characteristic peaks of citrus essential oils (C-H, C-C, and C<img>C bond vibrations) and sugars (C-H bending vibrations) at shifts of 756 cm⁻¹ , 1438 cm⁻¹ , 1602 cm⁻¹ , and 866 cm⁻¹ . In particular, off-flavor citrus exhibits significant changes in characteristic peaks, which related to changes in substance composition during flavor alteration. The intensity ratio of Raman characteristic peak indicates that D-limonene tends to degrade (I<sub>1438</sub>/I<sub>1529</sub> decreases), while the content of α-terpineol tends to increase (I<sub>1606</sub>/I<sub>1529</sub> increases) during the process of flavor quality change under different storage conditions. Machine learning results demonstrate that among the models used to identify off-flavor citrus, the Second-order Differentiation Support Vector Machine model performs optimally, achieving both accuracy and F-score of 100 %.

Cyclodextrins (CDs), which are tasteless and odorless, have garnered widespread attention due to their remarkable ability to mitigate off-flavors. They have been applied in plant-based products, dairy products, fruit juice, alcoholic beverages, and fish etc. In the present review, the volatile and non-volatile off-flavor compounds in foods were summarized first, and the mitigation mechanism of off-flavors by CDs were reviewed further. Additionally, various characterization methods were compared to investigate the mechanisms underlying the mitigation of off-flavors, including scanning electron microscopy, X-ray diffraction, Fourier-transform infrared spectroscopy, and molecular simulation etc. It is concluded that the primary mechanism by which CDs mitigate off-flavors involve the molecular encapsulation of odorants and precursors that cause off-flavors. Besides, the synergistic effect of cyclodextrins and other compounds further contribute to odor mitigation in foods, which should be paid more attention. β-cyclodextrin (β-CD) is generally applicable to five food systems, α-cyclodextrin (α-CD) and γ-cyclodextrin (γ-CD) may be more appropriate for smaller and larger molecules, respectively.
