Periodic Reporting for period 1 - AMINE_REMOVAL (Removing of biogenic amines of the wine by selective adsorption on functionalized porous solids)
Reporting period: 2016-06-01 to 2018-05-31
The main objective of this study was to synthesize functionalized materials that allow the selective removal of BA from wines evaluating also the effect on other wines components and on the organoleptic characteristics.
Amine_Removal has allowed the obtaining of a solid material based on functionalized silica that allows the partial removal of histamine, spermidine, spermine, cadaverine and putrescine from wines. For the application of the treatment in batch, solid dose should be adapted taking account the type of wine, initial contents of BA and the required removal considering the legal (or suggested) limits for the BA content. On the other hand, the effects on wine parameters and components were, in general, not significant or not negative for the organoleptic characteristics, except for some ethyl esters related with fruity aroma. In this sense, the effects on aroma depended on the wine type. Thus, in the case complex wines (aged on wood), the deviation of the aroma produced by the esters could be masked by the global wine aroma.
