METHOD OF PREVENTING OR REDUCING OFF-FLAVOR IN A BEVERAGE USING SILANE-TREATED SILICA FILTER MEDIA |
摘要 |
The present invention provides a method for preventing or reducing off-flavor in a beverage. Silane-treated silica filter media are synthesized. By contacting the beverage with the silane-treated silica filter, one or more off-flavor substances or off-flavor precursors bind to the silane-treated silica filter media and are removed. Beverages that tend to develop off-flavor upon storage such as alcoholic, fruit, and vegetable beverages, are suitable for the present invention. The present invention provides a method that can reduce the level of off-flavor substances such as trans-2-nonenal, diacetyl, and cis-3-nonenal. The present invention also provides a method that can reduce the level of off-flavor precursors such as linoleic acid. The silica filter media useful for the present method include rice hull ash, oat hull ash, or diatomaceous earth. |
