Abstract
The present invention relates to the treatment of particular filteraids to reduce the beverage soluble iron. In the method of the invention, a particulate filteraid, such as diatomite, is contacted with an aqueous solution of particular chelating agents. The process is applicable to treatment of loose filter media and is also applicable to the treatment of filter media in filter sheets. Lowering the pH during the time that the filter media is being contacted by the chelating agent produces an optimum affect.
Claims11
A method for reducing the iron content in beverages processed through a particulate filteraid by treating the filteraid prior to use as a filter for beverages by a method comprising contacting a particulate filteraid with a polydentate ligand to provide a treated filteraid, forming said filter aid into filter sheets comprising said filter aid and cellulose pulp and contacting said filter sheets with a beverage so as to form a complex between a substantial amount of beverage soluble iron contained in said beverage with said ligand.
