Abstract: Provided are methods for manufacturing a multi-ingredient beverage filter cartridge comprising the steps of: adding an amount of a first soluble beverage medium to the container having an internal bottom end, sidewall, and an access opening opposite the internal bottom end; leveling at least a portion of a top surface of the added first soluble beverage medium so that such top surface is substantially in the range of 1 mm to 11 mm from the internal bottom end; adhering a filter medium to the sidewall such that the filter medium does not contact the first soluble beverage medium, top surface; adding an amount of a second soluble beverage medium to the container such that the second soluble beverage medium forms a layer on top of the filter medium; and enclosing the container with a sealed lid.

Abstract: The invention relates to cellulosic composite compositions which contain cellulose derived from coffee parchment. The compositions are especially useful as coffee filters, but may also be used in any way traditionally used for cellulosic composite materials.
