Development and application of chemometrical methods based on 1H-NMR spectra of fruit juices – structural approach for analysis of wide and unbalanced datasets

• 1 H-NMR analysis with multivariate classification methods to authenticate fruit juices • standardized procedure to develop optimized classifying models for juice monitoring • guideline for selecting an optimal multivariate sampling method and a final model • fast and easy distinguishing organic orange juices from non-organic orange juices • fast and easy distinguishing NFC orange, apple and tomato juices from FC juices
