Patent

CA 2379509

The lees or "dregs" produced during wine making are rich sources of antioxidants. Unexpectedly, these materials show significant antibacterial properties as well as antioxidant properties. The lees of red wine which consist of tannins and plant pigments precipitated around crystals of potassium tartarate can advantageously be used directly as a tonic or demulcent. The material can also be used topically for disinfecting the skin, etc. In addition, it is possible to use organic polymers to bind the pigments and/or solubilize them from the tartaric salt to facilitate their use or to make a relatively pure pigment/tannin component.

Les lies ou résidus obtenus lors de la production du vin sont des sources riches en antioxydants. Ces produits présentent, de façon inattendue, des propriétés antibactériennes marquées ainsi que des propriétés antioxydantes. Les lies de vin rouge constituées par des tannins et des pigments végétaux précipités autour de cristaux de tartrate de potassium peuvent être avantageusement utilisées directement comme toniques ou émollients. Le produit peut également convenir, en usage local, pour désinfecter la peau, etc. En outre, il est possible d'utiliser des polymères organiques pour lier les pigments et/ou les solubiliser des sels tartriques en vue de faciliter leur emploi ou d'obtenir un composant pigment/tannin relativement pur.
