Study TitleEvaluation of the effects of chitosan films as a replacement for conventional sulphur dioxide treatment of white wines
Study Type1H-NMR metabolomics
Study SummaryIn 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.

Collection ID:CO002346
Collection Summary:After alcoholic fermentation, the wine was bottled in glass bottles (750 mL) under four different conditions: i) without preservation treatment (2 bottles); ii) addition of 40 mg/L of free SO2 (4 bottles); addition of iii) a Ch-Ge film with 100 cm2 surface area (5 bottles) and iv) a Ch-Ge film with 25 cm2 surface area (3 bottles). All wine samples were stored in the absence of light at 10-15 ºC, for 12 months. After opening the bottles, the wine samples were immediately prepared for NMR analysis.
