Description

  The present invention relates to a composition for a dietary supplement.

  L-arginine is one of the conditional essential amino acids, and is known to have effects such as recovery from fatigue, immunity improvement, and blood flow improvement, and is used as an active ingredient in dietary supplements. In particular, a sufficient amount of replenishment is desired under the invasion of trauma, pressure ulcer, infection, and the like. Against this background, dietary supplements containing L-arginine are currently commercially available (for example, Non-Patent Document 1).

Isocal Jelly Arg (Nestlé Health Science Japan https://www.nestlehealthscience.jp/Products/jellyArg)

  However, L-arginine has a unique taste (bitterness, egumi, etc.). Nutritional supplements containing L-arginine currently on the market are often supplemented with other components (such as sweeteners) for suppressing the taste of L-arginine (Non-patent Document 1). However, even if a sweetener is added, the taste of L-arginine cannot be sufficiently suppressed, and other problems such as the aftertaste peculiar to sweeteners appear, and as a result, it becomes easy to eat. The current situation is that it has not been reached.

  Moreover, in the dietary supplement currently marketed, there exist a powder form, a tablet, a capsule, and a jelly type. Powders, tablets, and capsules are difficult to take alone, and must be taken with water. For this reason, taking L-arginine is a heavy burden for patients who are subject to moisture restriction or for bedridden patients (eg, pressure ulcer patients). Moreover, even if it is a healthy person, it is not easy to take powder, a tablet, and a capsule during and immediately after exercise. For this reason, as a form of a dietary supplement, a liquid or jelly type is desirable. Furthermore, the daily dose of pressure ulcer patients with many dietary supplements having a low L-arginine concentration relative to the desired dose is preferably 5 g.

  However, the jelly-type conventional product (for example, Non-Patent Document 1) has an L-arginine content of 2.5 g out of 66 g. Therefore, pressure ulcer patients must drink 2-5 bottles a day. For this reason, the burden of taking the patient is immeasurable. Further, in any of powder, tablet, capsule, and jelly type, when the concentration of L-arginine is increased, the above-mentioned problem of the taste of L-arginine becomes more serious.

  Therefore, the present invention provides a composition for dietary supplements containing L-arginine that sufficiently masks the taste of L-arginine. The present invention also provides a composition for a liquid or jelly-type dietary supplement that has an extremely high L-arginine content and is easy to take.

  The composition for a dietary supplement of the present invention comprises L-arginine, a taste masking agent containing a carboxyl group or an organic phosphate group, and water, and the molar concentration of the L-arginine is Amol / L. When the molar concentration of the taste masking agent is defined as Bmol / L, the number of functional groups of the taste masking agent is defined as x, and the valence of the functional group is defined as y, A / B ≦ x · y It is characterized by being.

  It is preferable that the concentration of the L-arginine with respect to 1 L of water at 20 ° C. is larger than 148.7 g / L. The taste masking agent preferably contains at least one of citric acid, phytic acid, succinic acid, acetic acid, tartaric acid, lactic acid, glutaric acid, and fumaric acid. Moreover, it is preferable that at least any one of L-ornithine and citrulline is included. Furthermore, it is preferable that thickening polysaccharide is included.

  According to the present invention, it is possible to provide a composition that has an extremely high content of L-arginine and is easy to take.

  The composition for a dietary supplement includes an amino acid, a taste masking agent, a dissolution enhancer, and water.

  As amino acids, L-arginine (5-guanidino-2-aminopentanoic acid (5-guanidino-2-aminovaleric acid)), L-ornithine (2,5-diaminopentanoic acid), citrulline (2-amino- 5- (carbamoylamino) pentanoic acid), lysine and the like.

  A taste masking agent is a compound that suppresses the taste of amino acids. The taste masking agent preferably has a functional group that promotes ionization of amino acids in water. The amino acid is ionized in water, so that the taste of the amino acid is suppressed.

  The causal relationship between ionization of amino acids and suppression of amino acid taste is presumed as follows. By the ionization of amino acids, functional groups that make the taste of amino acids ionize. It is speculated that the taste of amino acids is suppressed by ionization of this functional group.

  In addition, when an amino acid is L-arginine, the functional group which makes the taste of L-arginine is a guanidyl group. The functional group that tastes L-ornithine is an amino group, and the functional group that tastes citrulline is an amino group.

  The functional group that promotes ionization of amino acids preferably has an acidic functional group or a basic functional group. Examples of the acidic functional group include a carboxyl group and an organic phosphate group.

  Examples of the taste masking agent include organic acids such as citric acid, phytic acid, succinic acid, acetic acid, tartaric acid, lactic acid, glutaric acid, and fumaric acid.

Here, the molar concentration of the amino acid whose taste is to be suppressed is Amol / L, the molar concentration of the taste masking agent is Bmol / L, the number of functional groups that promote ionization of amino acids is x, and the valence of this functional group is y And when we define each
(Formula 1) A <= B * x * y
It is preferable that

  The dissolution accelerator is a compound that improves the solubility of amino acids in water, and is preferably an acid that promotes ionization of amino acids in water. As the dissolution accelerator, it is preferable to use a compound applicable to the taste masking agent. Thereby, the effect of a dissolution accelerator and a taste masking agent can be exhibited with one compound.

  Addition of a solubility enhancer increases the solubility of L-arginine in water. For example, the solubility of L-arginine in water at 20 ° C. is 148.7 g / L, but the solubility of L-arginine in water at 20 ° C. is greater than 148.7 g / L by the addition of a solubility promoter. As the addition amount of the dissolution accelerator, the above-described formula 1 may be applied.

  As the composition, a thickening polysaccharide may be further added. By adding the thickening polysaccharide, a jelly-like composition can be obtained. Whether the thickening polysaccharide is added or not is not required to add the thickening polysaccharide when a liquid is desired as the final composition state. On the other hand, if a jelly shape is desired as the final composition state, a thickening polysaccharide may be added.

  A thickening polysaccharide is a water-soluble polysaccharide having a high viscosity. Examples include glucomannan, guar gum, locust bean gum, tamarind gum, carrageenan, xanthan gum, gum arabic, karaya gum, pectin, agar, alginic acid, sodium alginate, propylene glycol alginate, gellan gum, pullulan, curdlan and the like. For example, guar gum, locust bean gum, and tamarind gum are obtained by extraction from legume fruit. Carrageenan is obtained by extraction from algae. Pectin is obtained from citrus fruits, apples and the like. Xanthan gum and curdlan are obtained from microorganisms. Thickening polysaccharides further include those used as thickening stabilizers. A thickening polysaccharide may be used independently or may be used in combination of 2 or more type.

  In the present invention, materials, additives, and the like that are commonly used in foods and pharmaceuticals can be used as appropriate as long as the effects of the present invention are not impaired. For example, sweeteners (aspartame, stevia, sucralose, erythritol, etc.), acidulants (malic acid, ascorbic acid, phytic acid, etc.), excipients (dextrin, starch, reduced maltose, etc.), preservatives (sodium benzoate, paraoxy Benzoic acid etc.), pH adjusters (phytic acid etc.), fragrances, fruit juices, colorants etc. can be used. These materials and additives are appropriately added in each step by a method commonly used by those skilled in the art.

  According to the present invention, unique tastes such as L-arginine can be suppressed. Further, according to the present invention, a liquid or jelly-like product having a high content ratio of L-arginine or the like can be produced. As a result, the production cost and distribution cost of the composition can be reduced.

  The method for producing the composition for a dietary supplement is not particularly limited, but after adding an amino acid, a taste masking agent, and a dissolution accelerator to water and dissolving it, other additives such as thickening polysaccharides are added. An agent may be added.
