Abstract
Abstract A highly stabilized, balanced nutritive composition useful in supplementing the diet of humans and/or animals so as to insure an adequate intake of a wide range of the essential nutrients. The composition can be prepared and marketed in either liquid or dry granular form, and includes ascorbic acid, metabolically available iron, and gelatin. The gelatin has been found to stabilize the ascorbic acid in the presence of iron and other recommended nutrients, and additionally, provides a natural source for nearly all of the essential amino acids. Further, the composition may and preferably does include all of the other recommended nutrients, without adversely affecting the stabilized nature of the nutritive composition.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
69 words
A highly stable aqueous solution useful as a nutritive supplement or nutritive composition and comprising water, ascorbic acid and metabolically available iron in quantities suitable for supplementing the human diet and materially assisting in assuring the intake of the recommended daily allowances thereof, and gelatin in such quantity as to effectively retard the deterioration of the ascorbic acid in the presence of the iron and without gelling the solution.
Claim 2
Dependent Claim
69 words
A highly stable aqueous solution useful as a nutritive supplement or nutritive composition and comprising water, ascorbic acid and metabolically available iron in quantities suitable for supplementing the human diet and materially assisting in assuring the intake of the recommended daily allowances thereof, and gelatin in such quantity as to effectively retard the deterioration of the ascorbic acid in the presence of the iron and without gelling the solution.
Claim 3
Dependent Claim
24 words
The aqueous solution as defined in claim 1 wherein the concentration of the gelatin with respect to the water is less than about 0.4%.
Claim 4
Dependent Claim
25 words
The aqueous solution as defined in claim 1 wherein the concentration of the gelatin with respect to the water is between about 0.1% to 0.4%.
Claim 5
Dependent Claim
106 words
A highly stable aqueous solution useful as a nutritive supplement or nutritive composition and characterized by substantial stability of the various ingredients in the presence of each other, and comprising water, ascorbic acid, metabolically available iron, gelatin, and other vitamins, minerals or other ingredients not subversive of the above characteristics, with the ascorbic acid and iron being present in such quantities as are suitable for supplementing the human diet and materially assisting in assuring the intake of the recommended daily allowances thereof, and with the gelatin being present in such quantity as to effectively retard the deterioration of the ascorbic acid and without gelling the solution.
Claim 6
Dependent Claim
106 words
A highly stable aqueous solution useful as a nutritive supplement or nutritive composition and characterized by substantial stability of the various ingredients in the presence of each other, and comprising water, ascorbic acid, metabolically available iron, gelatin, and other vitamins, minerals or other ingredients not subversive of the above characteristics, with the ascorbic acid and iron being present in such quantities as are suitable for supplementing the human diet and materially assisting in assuring the intake of the recommended daily allowances thereof, and with the gelatin being present in such quantity as to effectively retard the deterioration of the ascorbic acid and without gelling the solution.
Claim 7
Independent Claim
92 words
The method of preparing a highly stable nutritive composition comprising the steps of preparing an aqueous solution comprising water, gelatin, and metabolically available iron, and then adding ascorbic acid to the solution, with the iron and ascorbic acid being present in such quantities as are suitable for supplementing the human diet and materially assisting in assuring the intake of the recommended daily allowances thereof, and the gelatin being present in such quantity to effectively retard the deterioration of the ascorbic acid in the presence of the iron and without gelling the solution.
Claim 8
Independent Claim
92 words
The method of preparing a highly stable nutritive composition comprising the steps of preparing an aqueous solution comprising water, gelatin, and metabolically available iron, and then adding ascorbic acid to the solution, with the iron and ascorbic acid being present in such quantities as are suitable for supplementing the human diet and materially assisting in assuring the intake of the recommended daily allowances thereof, and the gelatin being present in such quantity to effectively retard the deterioration of the ascorbic acid in the presence of the iron and without gelling the solution.
Claim 9
Dependent Claim
35 words
The method as defined in claim 5 wherein the step of preparing an aqueous solution includes heating a solution which comprises water and gelatin, and then adding the metabolically available iron to the heated solution.
Claim 10
Independent Claim
117 words
The method of preparing a highly stable nutritive composition in a water miscible dry form, and suitable for mixing in a conventional beverage or adding to other food products, comprising the steps of preparing an aqueous solution comprising ascorbic acid, metabolically available iron, and gelatin, with the ascorbic acid and iron being present in such quantities as are suitable for supplementing the human diet and materially assisting in assuring the intake of the recommended daily allowances thereof, and with the gelatin being present in such quantity as to effectively retard the deterioration of the ascorbic acid in the presence of the iron and without gelling the solution, and then drying the solution to produce a dryed product.
Claim 11
Independent Claim
117 words
The method of preparing a highly stable nutritive composition in a water miscible dry form, and suitable for mixing in a conventional beverage or adding to other food products, comprising the steps of preparing an aqueous solution comprising ascorbic acid, metabolically available iron, and gelatin, with the ascorbic acid and iron being present in such quantities as are suitable for supplementing the human diet and materially assisting in assuring the intake of the recommended daily allowances thereof, and with the gelatin being present in such quantity as to effectively retard the deterioration of the ascorbic acid in the presence of the iron and without gelling the solution, and then drying the solution to produce a dryed product.
Claim 12
Dependent Claim
19 words
The method as defined in claim 7 wherein the drying step is carried out in the absence of heat.
