ABSTRACT

Purple passion fruit is highly appreciated for its distinctive sweet flavour, low acidity, and aromatic profile, making it a desirable choice for fresh consumption and juice production. To ensure microbiological safety and extend shelf life, juice products typically undergo thermal pasteurization, which can alter their physicochemical properties and volatile composition, and ultimately impact consumer perception. However, the dynamics of the purple passion fruit volatilome, from fresh fruit to processed juice during storage, remain poorly understood. This study aimed to comprehensively characterize these transformations using an advanced analytical technique (two‐dimensional gas chromatography coupled with time‐of‐flight mass spectrometry).
