20090035431 | Filter Layer - The invention relates to a filter layer containing an adsorbent for the directed removal of a substance which adversely affects the taste from a fluid composition, in particular from wine. As adsorbent, particular preference is given to using a zeolite which has the periodic structural unit (PSU) of faujasites, in particular with a ratio of Si/Al of ≧5, preferably ≧10. The filter layer of the invention is able to remove 2,4,6-trichloroanisole (mainly responsible for the cork taste) from wine; other advantageous flavours are, in contrast, largely not removed. | 02-05-2009 |
