Abstract
Abstract A nonhygroscopic pulverulent composition for preparing beverages with a lasting effervescence comprises a first component or group of components mixed with a second component or group of components capable of reacting mutually in the presence of water to evolve a gas. Each of said components or group of components is impregnated with the dry residue of a saccharose liquor or of a saccharose derivative liquor containing a water-soluble or a mixture of water-soluble polymers.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
64 words
A pulverulent effervescent, water-soluble, non-hygroscopic composition for use as the basis for diet or soft drinks, said composition comprising a mixture of components in particulate form capable of reacting mutually in the presence of water to evolve gas, characterized in that each of the particulate components is impregnated with the dry residue of a heat-treated saccharose or saccharose derivative ethanolic liquor containing gum arabic.
Claim 2
Dependent Claim
64 words
A pulverulent effervescent, water-soluble, non-hygroscopic composition for use as the basis for diet or soft drinks, said composition comprising a mixture of components in particulate form capable of reacting mutually in the presence of water to evolve gas, characterized in that each of the particulate components is impregnated with the dry residue of a heat-treated saccharose or saccharose derivative ethanolic liquor containing gum arabic.
Claim 3
Dependent Claim
31 words
A composition according to claim 1, wherein the heat treated ethanolic liquor has been subjected to a thermal treatment in an airtight container heated to a temperature of about 50° C.
Claim 4
Dependent Claim
48 words
A composition according to any one of claims 1 and 2, wherein a first component of the mixture comprises a salt or a mixture of salts of carbonic acid and wherein a second component of the mixture comprises an acid or a mixture of organic and/or inorganic acids.
Claim 5
Dependent Claim
65 words
A composition according to claim 3, wherein the acid or acids is selected from the group consisting of citric, tartaric, malic, ascorbic and orthophosphoric acid and mixtures thereof and wherein the salt is selected from the group consisting of a carbonate or a bicarbonate of an alkali metal, a carbonate of an alkali earth metal, and the salt of carbonic acid and an amino acid.
Claim 6
Dependent Claim
31 words
A composition according to claim 1, wherein at least one component of the mixture contains at least one member selected from the group consisting of sweeteners, colouring agents, and flavouring agents.
Claim 7
Dependent Claim
13 words
A composition according to claim 1, wherein the ethanolic liquor includes tragacanth gum.
Claim 8
Independent Claim
150 words
A method for preparing a pulverulent effervescent, water-soluble, non-hygroscopic composition for use as the basis of diet or soft drinks, said composition containing a mixture of components in particulate form capable of reacting mutually in the presence of water to evolve gas, which comprises (a) preparing a solution of saccharose or saccharose derivative in water containing a macromolecular polysaccharide or mixture of macromolecular polysaccharides which are water-soluble but insoluble or only partially soluble in ethyl alcohol; (b) adding ethyl alcohol to the above solution while stirring, to form a liquor; (c) storing the thus obtained liquor in an airtight container at a temperature of about 50° C.; (d) separately impregnating or coating the particles of each of said components with the liquor resulting from step (c) above; (e) separately drying the thus impregnated or coated particles; and (f) mixing together the dried impregnated or coated particles in the desired proportions.
Claim 9
Independent Claim
150 words
A method for preparing a pulverulent effervescent, water-soluble, non-hygroscopic composition for use as the basis of diet or soft drinks, said composition containing a mixture of components in particulate form capable of reacting mutually in the presence of water to evolve gas, which comprises (a) preparing a solution of saccharose or saccharose derivative in water containing a macromolecular polysaccharide or mixture of macromolecular polysaccharides which are water-soluble but insoluble or only partially soluble in ethyl alcohol; (b) adding ethyl alcohol to the above solution while stirring, to form a liquor; (c) storing the thus obtained liquor in an airtight container at a temperature of about 50° C.; (d) separately impregnating or coating the particles of each of said components with the liquor resulting from step (c) above; (e) separately drying the thus impregnated or coated particles; and (f) mixing together the dried impregnated or coated particles in the desired proportions.
Claim 10
Dependent Claim
55 words
Method according to claim 7, wherein the liquor of water-soluble macromolecular polysaccharides resulting from step (c) comprises approximately 100 parts by weight of an approximately 50:50 mixture of saccharose or of a saccharose derivative and of gum arabic, and approximately 64 parts by weight of an approximately 40:24 mixture of water and of ethyl alcohol.
Claim 11
Dependent Claim
56 words
Method according to claim 7, wherein the liquor of water-soluble macromolecular polysaccharides resulting from step (c) comprises approximately 110 parts by weight of an approximately 60:40:10 mixture of, respectively, saccharose or a saccharose derivative, gum arabic and tragacanth gum, and approximately 96 parts by weight of an approximately 80:16 mixture of water and of ethyl alcohol.
Claim 12
Dependent Claim
14 words
Method according to claim 7, wherein the composition comprises a mixture of two components.
Claim 13
Dependent Claim
75 words
A method according to claim 7, wherein at least one of the components itself comprises a mixture of at least two members, one member selected from the group consisting of a salt of carbonic acid, an organic acid and an inorganic acid, and at least one member selected from the group consisting of a sweetener, a coloring agent, an essential oil, and an extract of caffeine, of quinine, of tolu balsam or of cola nuts.
Claim 14
Dependent Claim
28 words
Method according to claim 7, wherein the impregnation or coating or particles is carried out by mixing the particles of selected components with the liquor under mechanical pressure.
Claim 15
Dependent Claim
25 words
Method according to claim 7, wherein at least one of the selected components is impregnated by dissolving the selected components and the liquor in water.
Claim 16
Dependent Claim
