Description

  The present invention relates to a calcium-containing agent containing calcium derived from seawater.

The Japanese are generally considered to be overdose of sodium (about 12 g / day in terms of salt), and the goal is to take less than 10 g / day of salt.
Calcium is an essential mineral for maintaining the formation of bones and teeth and is an important mineral for the human body, but the average intake is below the nutritional requirement. Calcium is an important mineral that is defined as a nutrient of functional nutritional food as a nutrient necessary for bones and teeth. Calcium intake is deficient due to changes in Japanese dietary habits and results of 2010 national health and nutrition survey (Ministry of Health, Labor and Welfare) Then, it is a low value compared with the Japanese dietary intake standard (2005 version). Since calcium cannot be supplemented simply by ingestion from normal foods, supplements are made from fortified foods such as calcium-enriched milk and calcium supplements in the form of granules, tablets, capsules, and drinks. Calcium agents for the production of are desired.
There is a report that magnesium is lacking about 150 mg per day. Animal experiments have pointed out increased blood pressure, increased blood lipids, and narrowed blood vessel diameter due to magnesium deficiency.
As for potassium, nutritional requirements are sufficiently satisfied at present.
As a calcium agent raw material, Patent Document 1 (Japanese Patent Laid-Open No. 2003-33158) utilizing minerals, Patent Document 2 utilizing Japanese coral fossils (Japanese Patent Laid-Open No. 8-38104), and Patent Document 3 (Japanese Patent Laid-Open No. 2004-2004). No. 267085).
The ocean is an infinite resource for Japan, which has few resources. Patent Document 4 (Japanese Patent Laid-Open No. 10-313823) and Patent Document 5 (Japanese Patent Laid-Open No. 2002-172392) utilize minerals contained in seawater, which is a marine resource. The technology of patent document 6 (Unexamined-Japanese-Patent No. 2004-65196) and patent document 7 (Unexamined-Japanese-Patent No. 2001-295974) is disclosed.
The main mineral components in seawater are contained in the order of Na>Mg>Ca> K. Many kinds of minerals necessary for ingestion are abundantly contained, but as it is, sodium is excessive, and even if sodium is removed, the composition is rich in magnesium and has a strong bitterness that is difficult to use. Excluding sodium chloride, the magnesium component is the largest, containing about three times as much calcium. Magnesium and sodium have bitterness and entanglement (itchiness), and there is a limit to the use for food only by desalting sodium chloride.
In general, the main component is the composition shown in Table 1.

However,% is weight%.

  The present invention focuses on seawater containing various minerals and searches for mineral supply sources and easy-to-use dosage forms by changing the composition of the main mineral components, and is derived from seawater, preferably calcium as a main component. An object of the present invention is to provide an agent containing appropriate amounts of magnesium and sodium.

  The present invention uses seawater as a raw material, lowers the ratio of magnesium and sodium, and adjusts to increase the composition ratio of calcium. A calcium-containing agent mainly composed of calcium is proposed. The calcium-containing agent is preferably liquid. Suitable as a liquid calcium enriched beverage.

The main configuration of the present invention is as follows.
1. A calcium-containing agent derived from seawater, comprising at least three mineral components of calcium, magnesium, and sodium, wherein the weight ratio of calcium to magnesium (Ca / Mg) is 5 or more.
2. The calcium-containing agent according to 1., wherein the weight ratio of calcium and sodium (Ca / Na) is 1 or more.
3. The weight composition ratio of the three mineral components of calcium, magnesium and sodium is characterized in that Ca: Mg: Na is 1.0: 0.007 to 0.2: 0.005 to 1.0. 1. Or 2. The calcium-containing agent as described.
4. The calcium-containing agent according to any one of 1 to 3, which contains 1% by weight or more of calcium.
5. The calcium-containing agent according to any one of 1 to 4, which is a food additive.
6. The calcium-containing agent according to any one of 1. to 5. which is liquid.
7. A calcium beverage containing the calcium-containing agent according to any one of 1. to 5.

  The present invention has developed a calcium-containing agent derived from seawater, preferably calcium-based and preferably liquid. A calcium-containing agent having a calcium-rich composition was realized by adjusting the weight ratio of calcium and magnesium (Ca / Mg) and the weight ratio of calcium and sodium (Ca / Na). Calcium, magnesium and sodium are blended in a well-balanced manner, preferably containing other known trace mineral components derived from seawater (eg, potassium, iron, silicon, etc.) and useful as various mineral supplements. It is. Since the influence of magnesium and sodium has been reduced, there is little adverse effect on taste when used as a food additive, and versatility has expanded. It can also be used as a directly ingested beverage.

The present invention is a calcium-containing agent rich in calcium containing abundant types of minerals made from seawater, preferably a liquid calcium-containing agent.
As examples, seawater off Sakagoe, Ako City, Hyogo Prefecture was collected and analyzed for minerals. As a result, it was sodium 10,000 mg / liter, magnesium 1,200 mg / liter, and calcium 365 mg / liter.
Using this seawater, minerals are concentrated and separated by various methods to produce samples with different weights of calcium, magnesium, and sodium, taste evaluation is performed, and details are described below.

Hereinafter, preferred embodiments will be described. Since magnesium is contained in seawater about three times as much as calcium, the influence of magnesium is too great for components other than sodium chloride. This is adjusted to finish in a preferable state rich in calcium.
As a production method, calcium is recovered from raw seawater and concentrated, for example, in the process of heating and concentrating seawater, a precipitate is collected using a precipitation difference, and this precipitate is preferably water. Alternatively, by re-dissolving in sea water or a mixture thereof, and further adding a concentration process, the mineral composition of the remaining dissolved solution can be changed according to the precipitation difference. A residual solution having a desired mineral composition can be collected to obtain a liquid calcium preparation having the composition ratio of the present invention.
Moreover, the liquid calcium containing agent can also be obtained by re-dissolving the deposit which precipitated in the process of concentrating seawater, exchanging the positive ion and negative ion in a liquid, and adding a concentration process further. A liquid calcium-containing agent using only seawater as a raw material can also be obtained by combining the above methods.
The production method will be described with respect to the concentration method and the ion exchange bittern method, but is not limited thereto.

<Concentration method>
Taking the process of concentration while evaporating water from seawater as an example, the order of precipitation of the main components is calcium carbonate, calcium sulfate, and sodium chloride. Other trace mineral components are also precipitated and mixed in the middle. The deposition order is not clearly divided, but is deposited while overlapping, so that the composition ratio of the elements contained in the precipitate varies depending on the sampling time.
The precipitate is collected at the timing when calcium carbonate and calcium sulfate mainly precipitate. This precipitate is low in solubility mainly with calcium carbonate and calcium sulfate, becomes a hardly soluble solid with this compound, and is a dosage form that is difficult to use. When hydrochloric acid is added to the precipitate and mixed, the precipitate is converted into highly soluble calcium chloride, and a high-concentration solution calcium agent can be obtained. The precipitate will also contain magnesium, sodium, and the like.
When sodium carbonate is added during the concentration process, the proportion of calcium carbonate in the precipitate increases, so the mixing ratio of the magnesium compound can be lowered. Moreover, it will also precipitate in the form of magnesium carbonate.
By controlling the timing of precipitation in the process of evaporating and concentrating moisture, the amount of sodium carbonate added, etc., it is calcium-rich and the ratio of elements contained in the precipitate can be adjusted. Since trace minerals other than the main elements calcium, magnesium and sodium are inevitably mixed, a calcium-rich liquid preparation containing trace minerals can be obtained. This liquid preparation may be made into a solid calcium-containing agent by, for example, concentrating to dryness.

<Ion-exchange bittern extraction method>
Nigari, which is a by-product of salt production using ion exchange, can be used as a raw material. The composition of this ion-exchange bittern is a compound of calcium chloride, magnesium chloride, and sodium chloride, and magnesium is contained more than calcium as in seawater, which is why it is called “bitter juice”.
Using this as a raw material, sodium carbonate is added to form calcium carbonate, which is precipitated and collected. The collected precipitate is rich in calcium and contains magnesium and sodium.
By adding hydrochloric acid to the precipitate, a liquid agent containing calcium chloride, magnesium chloride, sodium chloride and trace elements can be produced.
The ability to adjust the composition ratio of each element with the amount of sodium carbonate added and the timing of precipitation is performed in the same manner as in the above concentration method.

The liquid calcium preparation of the present invention thus obtained is rich in calcium and contains magnesium, sodium, potassium, and other trace minerals.
Ca / Mg of about 5 to 150 and Ca / Na of about 1 to 200 can be produced. The calcium content can be 1% by weight or more.

The present invention is suitable as a food additive or food. The types of food include meat products such as croquettes, sausages, hams, bacon, kamaboko, chikuwa, tsukudani, dried fish products such as dried and boiled and even smoked seafood, fried chicken, konjac, tofu, instant soup, Sprinkles, sake, soft drinks, fruit drinks, supplements, snacks, bread, rice cakes, liquid seasonings, miso, soy sauce, sake and the like.
Care must be taken when using it in liquid foods that aggregate when the amount of minerals such as milk and fermented milk increases, but it can be used especially for supplements, snacks, breads, soft drinks, etc. whose physical properties are not easily changed.
