Description
2113~86 PALATABLE LOW SALT SUBSTITUTES
1. Field of the Invention The present invention relates to compositions suitable as salt substitutes. In particular, the palatable compositions of the present invention comprise a nutritious, unique blend of various salt forms or, optionally, free acid forms, of a select group of organic acids, including Vitamin C. The compositions of the present invention also contain, but in relatively minor amounts, potassium chloride and sodium chloride.
1. Field of the Invention The present invention relates to compositions suitable as salt substitutes. In particular, the palatable compositions of the present invention comprise a nutritious, unique blend of various salt forms or, optionally, free acid forms, of a select group of organic acids, including Vitamin C. The compositions of the present invention also contain, but in relatively minor amounts, potassium chloride and sodium chloride.
2. Background of the Invention The overconsumption of sodium chloride has been blamed for a wide range of human ailments including high blood pressure, coronary disease and heart attacks.
Indeed, medical research has shown that a reduction in the amount of sodium salt intake can be accompanied by a corresponding decrease in the blood pressure of hypertensive patients. Thus, great emphasis has been placed on low "salt" diets in which most, if not all, the sources of sodium chloride salt are eliminated.
Many products abound in which the major constituent of the low "salt" formulation or salt substitute is potassium chloride or sodium iodide.
For example, "a sodium-free yet saline tasting composition of matter" is disclosed in United States Patent Number 2,968,566. Potassium chloride contributes about seventy percent by weight of the compositions described in particular examples of this patent, although the claimed composition can comprise from about forty to about ninety parts potassium chloride. Calcium 2113~8~
-ascorbate is only a minor constituent of the compositions disclosed in this patent. Language reciting a limitation of "from about four to about fifteen parts" of ascorbate (either as calcium ascorbate or as free ascorbic acid) appears as a specific element of the claims of this patent. Such a high proportion of potassium chloride, such as that disclosed in this patent, renders the resulting composition inherently susceptible to the bitter after taste of potassium chloride.
Vitamin C and its salts, including calcium ascorbate, are, of course, quite old in the art and have been utilized most commonly as stabilizers or preservatives, as well as in vitamin supplements.
Vitamin C has also been the subject of inventions relating to various granulation methods. For instance, Canadian Patent Number 846,155 discloses a method of granulating ascorbic acid with an alkali metal chloride.
More recently, United States Patent Number 5,077,310 discloses granulation products of calcium ascorbate which also contains a number of solid organic acids, including citric acid and ascorbic acid. The pH of the granulated product of this recent patent is preferably in the range of 5.5 to 7.0, and the product, thus, is described as being "prevented from being colored."
There, thus, remains a need for a dietary low "salt" substitute that possesses substantially all the desirable olfactory characteristics of conventional table salt, while significantly lowering the intake of sodium chloride. The discovery of such a palatable composition that is, in addition, able to provide nutritional amounts of calcium and Vitamin C would be a significant achievement.
' 2113~8~ -_ - 3 3. Summary of the Invention To the great surprise of the present applicants, the desirable palatable, dietary and nutritional characteristics, stated above, can be obtained in a composition having, as a principal component, the calcium salt of ascorbic acid. In particular, a palatable composition has been discovered which is suitable as a salt substitute and which comprises a mixture of about forty to about sixty percent by weight of the mixture (wt%) of the calcium salt of ascorbic acid, about five to about twenty-five wt% of the sodium salt of ascorbic acid, about fifteen to about twenty wt~ of sodium chloride and about one to about two wt% of potassium chloride. The palatable composition of the present invention may further contain free ascorbic acid in an amount that is up to about fifteen percent by weight of the mixture.
In a specific embodiment of the present invention, the palatable composition may also contain, in addition to the components described, above, the free acid, calcium salt, potassium salt, sodium salt or combinations thereof of at least one of the supplemental acids selected from the group consisting of gluconic acid, citric acid, tartaric acid or glutamic acid.
Consistent with the objectives of the present invention, the applicants have further found that palatable compositions, having a preferred salty and nonbitter taste, include those with a pH value of about 3.5 to about 5.5, most preferably, about 4 to about 5.
Yet another ob~ective of the present invention relates to providing a method of enhancing the flavor of comestible solid or liquid matter comprising the addition of an effective flavor-enhancing amount of at least one of the various palatable low "salt" substitute compositions disclosed or equivalent to those disclosed in the present specification.
It is a further objective of the present invention to provide palatable compositions that resist discoloration and absorption of atmospheric moisture.
Any further objectives of the present invention will be apparent to the reader skilled in the art upon further reflection of the contents of the present disclosure, including the detailed description, immediately following, which serves merely as a further illustration of specific embodiments of the instant invention.

4. Detailed DescriPtion of the Invention As described previously above, the present invention relates to a low "salt" substitute that possesses substantially all the desirable olfactory characteristics of conventional table salt, while significantly lowering the intake of sodium chloride.
In addition, the palatable composition of the present invention, provides nutritious amounts of an essential vitamin, Vitamin C, and an important dietary supplement, calcium ion. All this is obtained from a composition comprising a mixture of about forty to about sixty percent by weight of the mixture of the calcium salt of ascorbic acid, about five to about twenty-five percent by weight of the mixture of the sodium salt of ascorbic acid, about fifteen to about twenty percent by weight of the mixture of sodium chloride and about one to about 4 ~ ~
two percent by weight of the mixture of potassium chloride. The palatable composition of the instant invention may further comprise from zero, or close to zero, to about fifteen percent by weight of the mixture 5 of free ascorbic acid.
The calcium ascorbate component of the instant invention is preferably in crystalline granular form (See, for example, United States Patent Number 4,251,449), or, further, can be in the form of a dihydrate (See, for example, united States Patent Numbers 2,596,103 and 2,631,155).
In a preferred embodiment of the instant 15 invention, the pH of 3.5 grams of the palatable composition, when dissolved in 100 mL of distilled deionized water, should fall in the range of about 3.5 to about 5.5, preferably about 4 to about 5. Such preferred compositions have a more appealing, agreeable 20 taste.
Other preferred compositions include those in which the amount of the sodium salt of ascorbic acid and the amount of the free ascorbic acid are approximately 25 equal in the mixture that also contains calcium ascorbate, sodium chloride and potassium chloride.
Other suitable salt substitute compositions contain a mixture in which the amount of the calcium ascorbate present is about equal to the sum of the respective 30 amounts of sodium ascorbate, free ascorbic acid, if present, and sodium chloride.

Also, generally, the calcium ascorbate comprises about forty to about sixty percent by weight of the mixture, 3S preferably about fifty percent.
2113~86 In particular embodiments of the invention, the mixture of ascorbates and potassium chloride and sodium chloride is further supplemented by the free acid form of gluconic acid, citric acid, tartaric acid or glutamic acid. Alternatively, the calcium, potassium or sodium salts of these supplemental organic acids may be added. Likewise, any combination involving the free acid, calcium, potassium or sodium salts may be utilized. However, the presence of such supplemental ingredients are generally limited to about one to about ten percent by weight of the mixture, preferably about two to about six percent by weight.
The palatable composition of the present invention may further comprise other components that would have utility apparent to those of ordinary skill in the art. For instance, it may be useful to include binders (e.g., a water-soluble cellulose), a sugar, a repellant, a lubricant, other vitamins, flavoring agents, and the like.
The granulated composition should further be of a desirable size mesh, for example, in the range of about 20 mesh to about 80 mesh, preferably about 30 to about 50 mesh.
Preferred low salt compositions of the present invention may be prepared by the following method.
Mixtures such as those listed in the Table, were ground in a pestle mortar until the powder had an average particle size of about 80 to about 100 mesh.
