摘要： Blue honeysuckle fruits (Lonicera caerulea L.) is a small berry valued for its diverse bioactivities, though it presents challenges in storage and transportation. Volatile compounds are commonly linked to the quality of fruits and vegetables. This study examined the effects of controlled atmosphere (CA) storage on the quality and volatile composition of blue honeysuckle fruits. The fruits were stored under low CO2 (L-CO2: 5 % O2, 10 % CO2, and 85 % N2), high CO2 (H-CO2: 5 % O2, 20 % CO2, and 75 % N2), and normal condition (control) for 28 d. Results showed that L-CO2 optimally maintained physicochemical properties: highest total phenolic content (TPC, 55.61 mg GAE/g DW), lowest lipid peroxidation (MDA=319.03 nmol/g FW), and stable sugar/acid ratio. The volatile profiles were analyzed using gas chromatography coupled with mass spectrometry (GC-MS), electronic nose (E-nose), and gas chromatography coupled with ion mobility spectrometry (GC-IMS). H-CO2 treatment was most effective in stabilizing the volatile profile of stored fruits, preserving key aldehydes such as hexanal and 2-hexenal. Overall, L-CO2 treatment maintained physical and chemical properties, while H-CO2 treatment better preserved flavor by minimizing volatile loss and reducing off-flavor formation.
