Abstract
The disclosure provides a method for selectively removing sulfites, for example bisulfite anionic species, from a beverage comprising free sulfite by providing an effective amount of a non-ionic, solid phase material and contacting the beverage with the solid phase material thereby sequestering the free sulfite on the non-ionic, solid phase material and providing a beverage having a reduced amount of free sulfite that otherwise maintains the general chemical composition with which it started. The disclosure further provides a device for selectively removing sulfite from a beverage comprising a container for receiving a beverage comprising free sulfite, said container enclosing a non-ionic, solid phase material capable of sequestering free sulfite, and a modular apparatus comprising a sulfite capture module and optionally a sediment filter module or an aeration module. Optionally, the non-ionic solid phase material is food-safe.
