| titleOfInvention | Method for obtaining tannin extract isolated from grapes, obtained tannin extract and use thereof |
| abstract | Methods for obtaining tannin extracts isolated from grapes using grape seeds are provided. The method includes: preparing grape seeds as a source of tannins; preparing an aqueous solution of a polyphenol solubilizer selected from the group consisting of urea, compounds containing SO groups, and sodium hydroxide, the concentration of which is in the range of 1% by weight and 15%; single extraction in autoclave reactor; isolated and directly concentrated to yield isolated extract. The present invention also relates to the tannin extract obtained. The new tannin extract isolated from grape seed includes a mixture of tannins and non-tannins, the composition of which provides the extract with improved antioxidant and light fastness. Tannin extracts isolated from grape seeds also include colorants. |
