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 may be in liquid form, or in a dry granular form suitable for mixing in a conventional beverage or adding to other food products, 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: 4
Claim 1
Independent Claim 120 words
The method of preparing a highly stable nutritive composition in water miscible dry form, and suitable for mixing in a conventional beverage or adding to other food products, and comprising the steps of preparing an aqueous solution comprising water, gelatin, and metabolically available iron, drying the solution to produce a dried product, adding dry ascorbic acid to the dried product, 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 2
Independent Claim 120 words
The method of preparing a highly stable nutritive composition in water miscible dry form, and suitable for mixing in a conventional beverage or adding to other food products, and comprising the steps of preparing an aqueous solution comprising water, gelatin, and metabolically available iron, drying the solution to produce a dried product, adding dry ascorbic acid to the dried product, 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 3
Dependent Claim 24 words
The method as defined in claim 1 comprising the further subsequent step of reconstituting the dried product into a solution by adding water thereto.
Claim 4
Dependent Claim 24 words
The method as defined in claim 1 wherein the step of preparing an aqueous solution includes heating the solution to the boiling temperature thereof.
