  Rose sparkling wines are photosensitive products thus subject to degradation by photo-oxidation over time when they are exposed on shelves. Consequently, its color gradually loses the most vibrant hues coupled with changes in aroma and flavor. An alternative to increase the shelf life of sparkling wines is the usage of light stabilizers, such as UV Absorbers (UVA) and Hindered Amine Light Stabilizers (HALS), substances that, when added to the packaging used for sparkling wines has the purpose of stabilizing the material, protecting the product. The purpose of this study was to evaluate the quality of rosé sparkling wines looking at the following properties: hue, colorimetric intensity, anthocyanins index and chemical characteristics using FTIR and visible-UV of Low Density Polyethylene films (LDPE) used as a protective layer for the exterior of colorless bottles.
