Abstract
Abstract A water-soluble solid beverage cube, consisting of powdered glucose monohydrate, sucrose and hygroscopic flavor material, is prepared by mixing the ingredients, heating them above 95° F in a high humidity atmosphere, shaping the solidified mass and allowing the solid to cool. Additives may be added to the powdered mixture to increase the strength of the solid, improve its hygroscopic nature and alter its taste.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
81 words
A method of manufacturing a water-soluble solid beverage tablet comprising the steps of: forming a mixture consisting essentially of 16 to 40% powdered glucose monohydrate, 50 to 70% granular sucrose and 1 to 10% powdered hygroscopic flavor material, the sucrose being adjusted to give a total sugar content of between 90 and 95%; heating the mixture above 95° F in a sealed chamber until the mixture binds into a mass; forming the mass into predetermined tablet shapes; and cooling the tablets.
Claim 2
Independent Claim
81 words
A method of manufacturing a water-soluble solid beverage tablet comprising the steps of: forming a mixture consisting essentially of 16 to 40% powdered glucose monohydrate, 50 to 70% granular sucrose and 1 to 10% powdered hygroscopic flavor material, the sucrose being adjusted to give a total sugar content of between 90 and 95%; heating the mixture above 95° F in a sealed chamber until the mixture binds into a mass; forming the mass into predetermined tablet shapes; and cooling the tablets.
Claim 3
Dependent Claim
24 words
The method of claim 1 in which the step of cooling the tablets is performed by allowing the tablets to cool under atmospheric conditions.
Claim 4
Dependent Claim
16 words
The method of claim 1 in which said hygroscopic flavor material is a tea flavored material.
Claim 5
Dependent Claim
14 words
The method of claim 1 in which said mixture further includes secondary hygroscopic material.
Claim 6
Dependent Claim
14 words
The method of claim 1 in which said mixture further includes non-hygroscopic flavor material.
Claim 7
Dependent Claim
29 words
The method of claim 1 in which the step of forming the solid is performed by placing the powdered mixture in molds so that it solidifies directly into tablets.
