Abstract
Abstract Described is a novel composition of matter which is a natural red dyestuff composed of the ingredients: (i) a betalaine (red beet dye); (ii) Ascorbic acid or derivative or salt thereof (e.g. sodium ascorbate or isoascorbic acid [D-erythro-hex-2-enonic acid gamma lactone]); (iii) A phosphate (such as sodium hexametaphosphate and/or tetrasodiumphosphate) and, optionally, (iv) Ethylenediaminetetraacetic acid or a salt thereof. In addition, the foregoing composition may contain caramel color. Also described are processes of preparing such compositions and processes of adding same to foodstuffs, chewing gums and medicinal products.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
97 words
A composition having a stabilized red color comprising 100 parts by weight of red beet dye at 68° Brix and intimately admixed therewith an acid selected from the group consisting of ascorbic acid and erythorbic acid, the quantity range of said acid in said composition being from 15 to 30 parts by weight, and sodium hexametaphosphate, the quantity of said sodium hexametaphosphate being from 10 parts to 30 parts by weight of said composition, whereby said ascorbic acid derivative in combination with said sodium hexametaphosphate creates a light and heat stabilization effect on said red beet dye.
Claim 2
Dependent Claim
97 words
A composition having a stabilized red color comprising 100 parts by weight of red beet dye at 68° Brix and intimately admixed therewith an acid selected from the group consisting of ascorbic acid and erythorbic acid, the quantity range of said acid in said composition being from 15 to 30 parts by weight, and sodium hexametaphosphate, the quantity of said sodium hexametaphosphate being from 10 parts to 30 parts by weight of said composition, whereby said ascorbic acid derivative in combination with said sodium hexametaphosphate creates a light and heat stabilization effect on said red beet dye.
Claim 3
Dependent Claim
32 words
The composition of claim 1 having additionally added thereto ethylenediaminetetraacetic acid the quantity of ethylenediaminetetraacetic acid in said composition an effective amount of less than 20 parts by weight of said composition.
Claim 4
Dependent Claim
11 words
The composition of claim 1 wherein the acid is ascorbic acid.
Claim 5
Dependent Claim
22 words
The composition of claim 1 having an enhanced red color without a blue or violet sheen, having added thereto a caramel color.
Claim 6
Dependent Claim
36 words
A process for producing a dry dyestuff adjuvant for foodstuffs, said dyestuff being a red beet dye comprising the step of intimately admixing the composition of claim 1 with gum arabic and spray-drying the resulting composition.
Claim 7
Dependent Claim
43 words
The process for producing a dry dyestuff-containing additive for foodstuffs, said dyestuff being red beet dyestuff comprising the step of intimately admixing the composition of claim 1 with gelatin and encapsulating the resulting mixture by coacervating techniques whereby encapsulated color particules are produced.
Claim 8
Dependent Claim
29 words
A process comprising the step of intimately admixing a colorless foodstuff with the composition of claim 1 whereby a foodstuff having a red color which is stabilized is obtained.
