Abstract
A method for decolorizing a muscadine pomace grape extract by processing the clarified extract by ultrafiltration through a 500-5000 kDa microfiltration membrane to obtain a first permeate in which flavor components are removed. The retentate is subjected to ultrafiltration through a 25-100 kDa ultrafiltration membrane to obtain a second permeate and a second retentate. The polymeric condensed tannins are removed in the second retentate and the second permeate is the decolorized extract having increased levels of polyphenols and lowered levels of sugars and condensed tannins compared to the first retentate. The decolorized extract can be incorporated into skin care compositions, which can also include beta-glucan and grape seed extract. The skin care compositions can and applied to the skin to maintain healthy skin without discoloration, protecting against ultraviolet radiation, and inhibiting the production of anti-inflammatory mediators in skin cells.
