Project Title:Evaluation of the effects of chitosan films as a replacement for conventional sulphur dioxide treatment of white wines
Project Type:1H-NMR metabolomics
Project Summary:In this study, 1H-NMR metabolomics was used to evaluate the effects of using chitosan-genipin (Ch-Ge) films as replacement of sulfur dioxide (SO2) in white wines preservation, to circumvent adverse health consequences caused by SO2 intake, on the final compositional profile of white wines. To do so, differently sized Ch-Ge films (25 and 100 cm2) were tested, as well as SO2-tretment and untreated wines. The obtained data added important knowledge on the potential use of Ch-Ge films, particularly those of higher surface areas, as replacements for the use of SO2 in wine conservation, based on the changes noted in metabolite composition and their putative explanations in terms of wine chemical and biochemical characteristics.
