<p>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.</p> |
