Application of the E-Nose as a Non-Destructive Technique in the Early Detection of <i>Monilinia laxa</i> on Plum (<i>Prunus domestica</i> L.).

ABSTRACT: This study investigated the ability of an electronic nose system (E-nose) to detect early signs of fungal contamination in the red plum variety 'Black Splendor'. We focused on identifying changes in volatile organic compounds (VOCs) that occur with decay. For this purpose, we compared two groups of plums: a control group (healthy plums) and a group inoculated with Monilinia laxa. VOCs from both groups were analyzed and quantified using gas chromatography/mass spectrometry (GC/MS). In parallel, E-nose signals were recorded at two key moments of fungal development: an early and an intermediate phase. The results revealed a strong correlation between E-nose signals and the aromatic profile characteristic of fungal contamination in plums. Linear discriminant analysis (LDA) models, devel
