Principal component analysis (PCA) and orthogonal projection to latent structures-discriminant analysis (OPLS) supervised data analysis of modelling youngversus old mature fruit specimens analysed via SPME GC–MS for their volatile metabolites. PCA score (A) and loading plot (B) (n = 3); OPLS-DA score plot (C) and loading S-plot (D). Segregation in both score plots showed enrichment of alcohols, aldehyde and ketone compounds in young fruit.
