摘要：
The invention relates to a polyphenol extract from white-grape residue. The invention relates to a straightforward method with few steps for obtaining extracts having antioxidant and anti-bacterial properties from white-grape residue. Due to the characteristics white-wine production, which is carried out by exclusively fermenting the must squeezed from the grapes, without any contact with the remains of pulp, skin and seeds, the residue generated during the method (white-grape bagasse) is very rich in polyphenols, since smaller amounts of same are transferred to the wine. The proposed procedure uses non-contaminating materials, takes place under gentle conditions and prevents the obtained eluates from containing suspended solids, enabling extracts rich in bioactive polyphenols to be obtained, which can be used on an industrial scale, essentially in the cosmetic, pharmaceutical and/or food industries.
