Early Detection of Monilinia laxa in Yellow-Fleshed Peach Using a Non-Destructive E-Nose Approach

This study evaluated the performance of an electronic nose (E-nose) system for the early detection of fungal spoilage in yellow-fleshed peach (Prunus persica cv. ‘Carla’). Fruits were divided into two groups: one inoculated with Monilinia laxa and a non-inoculated control. Volatile organic compounds (VOCs) were identified and quantified via gas chromatography– mass spectrometry (GC–MS), while E-nose sensor responses were recorded at two post- inoculation stages: early and middle decay.
