Headspace fingerprinting as an untargeted approach to compare novel and traditional processing technologies: A case-study on orange juice pasteurisation

► Untargeted approach to compare novel and traditional processing technologies. ► Takes into account unexpected and unintended effects of (novel) processing. ► Volatile profile of heat, HP and PEF pasteurised orange juice comparable. ► During refrigerated storage, indirect impact differences (enzyme inactivation) revealed. ► Multivariate data analysis (PCA, PLS, PLS-DA).
