Claim 5:
6. A method for adsorbing proteins and/or metals from wine or other vegetable beverages, the method comprising at least one adsorption step wherein wine or other vegetable beverages is/are made to flow through a device comprising:
a tubular container filled internally at least partly with particles of support material coated with a layer of mesoporous nanostructured adsorbent material comprising titanium oxide, the layer having a thickness between 10 and 25 μm and the mesoporous nanostructured adsorbent material having pores of size between 15 and 50 nm, BET surface area between 90 and 100 m2/g and absorbent volume of the pores between 0.4 and 0.5 cm3/g;
an inlet conduit and an outlet conduit for a beverage to be stabilized, respectively positioned at the two ends of the tubular container, said inlet conduit and said outlet conduit being in fluid communication with the internal volume of the tubular container;
a first closure element and a second closure element, respectively positioned at the two ends of the tubular container, said inlet and outlet conduits passing through the first and second closure elements, wherein the first and the second closure elements are adapted to occlude a respective end section of the tubular container and to prevent escaping of the mesoporous nanostructured adsorbent material contained therein; and
a first filtering element positioned in an outlet section of the inlet conduit into the tubular container and a second filtering element positioned in an inlet section of the outlet conduit from the tubular container, the first and the second filtering elements having pores of dimensions adapted to retain inside the tubular container the particles of support material coated with the layer of mesoporous nanostructured adsorbent material,, to obtain adsorption of the of proteins and/or metals on the mesoporous nanostructured adsorbent material.
