Title:
METHOD FOR PREPARING PRESERVATIVES IN THE WINE INDUSTRY
Document Type and Number:
WIPO Patent Application WO/2014/060989
Kind Code:
A3
Abstract:
A method for the preparation of preservatives in the wine industry comprising in an operating sequence the following steps: - extraction in which a plant species with antioxidant and antimicrobial properties is subject to a flow of sub-critical carbon dioxide to obtain a phytoextract mixture; - separation in which the phytoextract mixture resulting from the primary extraction step is subject to chromatographic extraction by means of the action of sub-critical carbon dioxide in order to separate said phytoextracts as a function of their mass; - mixing in which a part of the phytoextracts obtained from the separation step are mixed together with the addition of water.
