Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
132 words
A substantially dry mix for preparing a carbonated liquid yogurt comprising: (a) powdered yogurt; (b) sufficient edible, solid, at least partially water-soluble acid to produce a liquid yogurt having a pH of less than 7 when the mix is combined with water; and (c) sufficient solid metal carbonate in an amount from about 0.05 to about 0.25 by weight metal carbonate per one part by weight powdered yogurt to produce a carbonated liquid by solution of the metal carbonate in water when the mix is combined with water, wherein the solid carbonate is a mixture of a bicarbonate that dissolves quickly in water and quickly releases carbon dioxide and a carbonate that dissolves slowly in water and slowly releases carbon dioxide in a weight ratio of from about 0.5:1 to about 2:1.
Claim 2
Dependent Claim
132 words
A substantially dry mix for preparing a carbonated liquid yogurt comprising: (a) powdered yogurt; (b) sufficient edible, solid, at least partially water-soluble acid to produce a liquid yogurt having a pH of less than 7 when the mix is combined with water; and (c) sufficient solid metal carbonate in an amount from about 0.05 to about 0.25 by weight metal carbonate per one part by weight powdered yogurt to produce a carbonated liquid by solution of the metal carbonate in water when the mix is combined with water, wherein the solid carbonate is a mixture of a bicarbonate that dissolves quickly in water and quickly releases carbon dioxide and a carbonate that dissolves slowly in water and slowly releases carbon dioxide in a weight ratio of from about 0.5:1 to about 2:1.
