Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an alginic acid-containing beverage having low saltiness and sourness.

[0002]

2. Description of the Related Art Alginic acid or its salt is known as a typical non-fermentable dietary fiber that is not assimilated by intestinal bacteria, and has recently attracted attention as a material having health effects such as improving bowel movements and suppressing cholesterol absorption. Has been done. Conventionally, when preparing an acidic beverage containing alginic acid, the pH has been adjusted to acidic with an organic acid such as citric acid, lactic acid, or malic acid after preparing a solution of neutral alginate. However, this production method has a problem that the concentration of metal ions released from alginate increases with a decrease in pH, the salty taste is enhanced, and the taste of the beverage is impaired. Furthermore, since the organic acid is added, the sourness of the beverage becomes unnecessarily strong, and there is a problem that it is difficult to adjust the appropriate sourness to suit the taste.

[0003]

An object of the present invention is to provide an alginic acid-containing beverage having a high content of alginic acid, which does not have strong salty taste or sourness.

[0004]

Means for Solving the Problems The present inventor has previously dispersed an insoluble alginic acid in water, and adjusted the pH by adding a carbonate to obtain an alginic acid-containing beverage having an excellent palatability in which saltiness and sourness were alleviated. It was found that it can be obtained.

The present invention provides an alginic acid-containing beverage obtained by adding carbonate or bicarbonate to alginic acid or a mixture of alginic acid and its salt and water.

BEST MODE FOR CARRYING OUT THE INVENTION Examples of the salt of alginic acid or a salt thereof (hereinafter referred to as alginic acid) used in the alginic acid-containing beverage of the present invention include alkali metal salts such as sodium salt and potassium salt. The sodium salt is preferred. Alginic acid has a weight average molecular weight of 200, which is measured by a high performance liquid chromatography (HPLC) method.
000 or less, preferably 100,000 or less, especially 4
It is preferably from 50,000 to 80,000.

Examples of carbonates used in the alginic acid-containing beverage of the present invention include alkali metal salts such as sodium salts and potassium salts, with sodium salts being particularly preferred. Examples of the bicarbonate include alkali metal salts such as sodium salt and potassium salt, and sodium salt is particularly preferable. As the carbonate or bicarbonate, sodium hydrogen carbonate is particularly preferable.

The alginic acid-containing beverage of the present invention preferably contains 0.1 to 50% by weight, preferably 0.2 to 20% by weight, particularly preferably 1 to 10% by weight, of alginic acid as alginic acid. The alginate is preferably used in combination of 0 to 2 parts by weight with respect to 1 part by weight of alginic acid for convenience of seasoning and production. The carbonate or bicarbonate added during the production of the alginic acid-containing beverage of the present invention is from 0.01 to
20% by weight, preferably 0.1-10% by weight, in particular 0.
It is preferred to add an amount corresponding to 1-5% by weight. The content weight ratio of the alginic acid (A) to the carbonate or bicarbonate (B) is (A) / (B) = 100/1 to 1/10,
It is preferably 10/1 to 1/1, particularly 6/1 to 3/1.

The alginic acid-containing beverage of the present invention comprises water or 5
By adding alginic acid or alginic acid and an appropriate amount of alginic acid in warm water heated to 0 ° C. or higher, preferably 50 to 60 ° C., first, carbonate or bicarbonate is added to an acidic liquid in which , Manufactured as a beverage adjusted to an appropriate pH. When using warm water, 50 ℃ or more,
It is preferable to set the temperature to 50 to 60 ° C. because dispersion and dissolution are easy. At this time, the pH was 3.8 at 20 ° C.
With the above, most of the alginic acid is dissolved to obtain a transparent or translucent beverage, and at a pH of less than 3.8, an insoluble alginic acid is obtained as a beverage.

The alginic acid-containing beverage of the present invention further comprises 2
The pH at 0 ° C is preferably 4.6 or less, but the range in which alginic acid can be sufficiently dissolved is 3.8 to 4.6.
Is preferred, and particularly when adjusted to 4.0 to 4.4, the balance between saltiness and sourness is further adjusted, and the palatability becomes excellent.

The pH adjusting agent is adjusted by a carbonate or bicarbonate to be added, and these are present as carbonate ions after dissolution, or the bicarbonate disappears as water and carbon dioxide, so that the acidity is excessive. It can be adjusted without being strongly resistant to water, and for the purpose of imparting an appropriate sourness, citric acid (crystalline or anhydrous), lactic acid, DL-malic acid, L-tartaric acid, DL
-Tartaric acid, acetic acid, oxycarboxylic acids such as fumaric acid, phosphoric acid or salts thereof may be adjusted alone or in combination, and in particular, citric acid (crystal), citric acid (anhydrous) commonly used in beverages, DL-malic acid, trisodium citrate, monopotassium citrate, tripotassium citrate, sodium lactate, DL-sodium malate are preferably used.

The viscosity of the alginic acid-containing beverage of the present invention is 2
20 mPa · s or less, preferably 4 to 15 mPa · s, especially 5 to 12 mPa · s, when measured with a B-type viscometer at 0 ° C., have a suitable fibrous texture and texture and throat It is preferable in that the workability becomes good. The viscosity can be adjusted by adjusting the molecular weight and content of alginic acid. Pectin, low molecular weight pectin, guar gum, low molecular weight guar gum, hemicellulose, gum arabic, glucomannan, locust bean gum, pullulan, xanthan gum, gellan gum. , Tara gum, psyllium seed gum, carrageenan, laminaran, curdlan, tamarind seed gum, karaya gum,
It may be adjusted by adding thickening polysaccharides such as tragacanth gum, carboxymethyl cellulose, and propylene glycol alginate.

In addition to these components, sweeteners, fruit juices, antioxidants such as vitamin C and the like may be added to the alginic acid-containing beverage of the present invention. It is preferable to add these components after returning the liquid in which the alginic acid is dissolved in carbonate or bicarbonate to room temperature. Further, since the pH may change by adding fruit juice, vitamin C, etc., the pH adjusting agent may be added to adjust the pH.

The alginic acid-containing beverage of the present invention is preferably used for health purposes such as supplementation of dietary fiber and improvement of bowel movements.
