Integration of non-target metabolomics and sensory analysis unravels vegetable plant metabolite signatures associated with sensory quality: A case study using dill (Anethum graveolens)

Using dill (Anethum graveolens L.) as a model herb, we reveal novel associations between metabolite profile and sensory quality, by integrating non-target metabolomics with data. Low night temperatures exposure to UV-enriched light was used modulate plant metabolism, thereby improving quality. Plant age is crucial factor associated accumulation of ether ?-phellandrene, volatile compounds flavour. However, analysis showed that neither these has any strong association taste. Rather, amino acids alanine, phenylalanine, glutamic acid, valine, leucine increased in samples exposed eustress were positively sour Increases organic changed the taste from lemon/grass more bitter/pungent dill-related Our procedure reveals approach establish links effects eustressors on quality may be applicable broad range crops.
