[Technical Field] The present invention relates to a calcium replenishment solution prepared using fish scales as a raw material and a method for producing the same. [Background Art] Fish scales contain around 20% calcium and are attracting attention as a source of calcium supplementation. In particular, the scales of sardines, which are caught in a huge amount in Japan, tend to peel off even when washed with water, and the huge amount of sardines that are caught in Japan means that a huge amount of scales come out, making it difficult to reuse them as a source of calcium. This is what is desired. However, fish scales cannot pass through the throat because they are flaky, and calcium cannot be absorbed into the body because the surface is covered by the epidermis. It is a thing,
There was a problem that it was difficult to use it as a calcium supplement source. [Object of the Invention] The present invention has been made in view of the above points, and its first object is to provide a calcium replenishment solution that can effectively absorb the calcium content of fish scales into the body. A second object of the present invention is to provide a method for producing a calcium replenishing solution that can easily produce such a calcium replenishing solution. [Disclosure of the Invention] The calcium replenishment solution according to the present invention is characterized by dissolving fish scales in a citric acid solution, and the method for producing the calcium replenishment solution according to the present invention includes: The present invention is characterized in that the fish scales are blended in a citric acid solution in the present state and the fish scales are dissolved in the citric acid solution.The present invention will be described in detail below. Fish scales can be used by simply washing them with water and drying or dehydrating them, but by soaking them in warm water at around 70 to 80 degrees Celsius, you can remove the fish odor and remove the collagen that adheres to the surface of the fish scales as a film. It is desirable to use the product after removing the mucilage.
By mixing and stirring the fish scales and an aqueous solution of citric acid, the fish scales are dissolved in the citric acid solution, and this solution is filtered to obtain a filtrate as a calcium replenishment solution. here,
Fish scales can be dissolved in a citric acid solution by mixing them with the citric acid solution in their flaky form, but it is necessary to crush the fish scales before dissolving them in the citric acid solution. Therefore, it is possible to easily produce a calcium replenishment solution. Of course, a calcium replenishment solution can also be prepared by dissolving crushed fish scales in a citric acid solution. Further, the higher the concentration of the citric acid solution, the higher the dissolution rate of fish scales, but it is usually preferable to set the concentration to about 1% to 10%. When the concentration is less than 1%, it becomes difficult to dissolve fish scales in the citric acid solution. The amount of fish scales added to the citric acid solution is
Of course, it is determined depending on the intended calcium content of the calcium replenishment solution, and it also varies depending on the concentration of the citric acid solution, but generally the dry weight is 10 g or more per 1 citric acid solution.
About 30g is preferable. The calcium replenishment solution prepared in this way can be used, for example, as part of the raw materials for nutritional drinks and nutrient-containing soft drinks, for the purpose of replenishing calcium content in these nutritional drinks and nutrient-containing soft drinks. Can be done. In this case, citric acid is used to add acidity to nutritional drinks and soft drinks, and the calcium replenishment solution according to the present invention, which is prepared by dissolving fish scales in citric acid, is used in nutritional drinks and soft drinks. This means that it can be used without any particular fear of impairing the taste of drinking water. Furthermore, citric acid is produced in the metabolic cycle of living organisms, known as the tricarboxylic acid cycle (citric acid cycle), and it goes without saying that it does not have any negative effects on the human body. Nor. In addition, as seen in the Examples and Comparative Examples below, fish scales can be dissolved with various organic acids, and especially malic acid, lactic acid, and acetic acid dissolve calcium in fish scales at a high dissolution rate. However, organic acids other than citric acid are inappropriate for calcium absorption into the body. That is, calcium is absorbed in the body mainly in the duodenum, and the pH of the biological fluid in the duodenum is 4.8 to 8.2. A solution prepared by dissolving fish scales in these organic acids has a pH of around 3, but when this solution reaches the duodenum, it is neutralized by biological fluids and the pH becomes high. At this time, with organic acids other than citric acid, as the pH increases, the dissolution rate of calcium decreases significantly and it precipitates as a precipitate, and the calcium precipitated as a precipitate is not absorbed into the body and is not absorbed by the body. This will result in a significant decrease in efficiency. Therefore, in the present invention, citric acid is selected and used as the organic acid for dissolving fish scales. Next, the present invention will be specifically explained with reference to Examples. Example 1 After washing the scales of sardine with water,
The scales were immersed in warm water of 70 to 80°C and left to stand for 10 minutes with occasional stirring to remove the fishy odor and the sticky substance (collagen) adhering to the surface of the scales. Next, the scales were washed again with water, pressed on a drainboard, and dehydrated for 5 minutes in a centrifuge to obtain sample fish scales with a water content of 30.6%. When the calcium in this fish scale was quantified, the total calcium content was 156.8 mg/g. To quantify calcium, accurately place approximately 5 g of fish scales in a platinum dish, carbonize at low red heat, transfer this to a 300 ml tall beaker with water, gradually add 10 ml of hydrochloric acid, and then add water to make approximately 100 ml. The mixture was boiled for about 5 minutes, and then after cooling, water was added to make exactly 500 ml, which was filtered through a dry filter paper, and then determined by the ethylenediaminetetraacetate method. Next, take 25g of these fish scales and add 2% citric acid solution (PH1.95) to it for 1 minute.
The mixture was shaken for 1 hour using a shaker at 30 to 40 revolutions, and water was added to make the total volume 2.5.
This solution was filtered through dry filter paper to obtain a filtrate as a calcium replenishment solution. When we measured the pH of the calcium replenishment solution obtained in this way and quantified the calcium content, we found that
The results shown in Table 1 were obtained. Calcium was determined by the ethylenediaminetetraacetate method, and the calcium solution ratio in the calcium replenishment solution is shown in the table. The dissolution rate can be calculated as a percentage of the calcium content of the calcium supplement solution divided by the calcium content of the fish scales. Example 2 A calcium replenishment solution was obtained in the same manner as in Example 1, except that a 5% aqueous solution (PH 1.80) was used as the citric acid solution. Comparative Examples 1 to 8 As organic acids for dissolving fish scales, 2% aqueous malic acid solution (Comparative Example 1), 5% aqueous malic acid solution (Comparative Example 2), and 2% aqueous lactic acid solution (Comparative Example 3) , 5% aqueous lactic acid solution (Comparative Example 4), 2
% aqueous tartaric acid solution (Comparative Example 5), 5% aqueous tartaric acid solution (Comparative Example 6), 2% aqueous acetic acid solution (Comparative Example 7), 5% aqueous acetic acid solution (Comparative Example 8), etc. A calcium replenishment solution was obtained in the same manner as in Example 1. As shown in Table 1, in Examples 1 and 2 using citric acid solution, most of the calcium contained in the fish scales was dissolved, confirming that the fish scales can be easily dissolved in the citric acid solution even when they are present. be done. In addition, regarding the calcium replenishment solutions of Examples 1 and 2 and Comparative Examples 1 to 8 obtained as described above,
Adjust the pH using 0.1684N sodium hydroxide aqueous solution.
Neutralized to 7.0. At this time, except for Examples 1 and 2 in which a citric acid solution was used, precipitation occurred when the pH reached 5.0 to 6.5. The solution whose pH was adjusted to 7.0 was filtered, and the calcium content of the filtrate was measured.
Table 1 shows the measurement results of calcium content and the calcium dissolution rate calculated based on the measurement results. As shown in Table 1, in Examples 1 and 2 using citric acid solutions, the dissolution rate decreased only slightly and almost no precipitation occurred, whereas in each comparative example, the dissolution rate decreased and no precipitation occurred. It is confirmed that many cases occur. Therefore, if the calcium replenishment solution is neutralized by biological fluids in the duodenum, there is a risk that some of the calcium in each comparative example will precipitate, reducing the absorption efficiency of calcium into the body. However, in Examples 1 and 2 in which citric acid was used, almost no calcium was precipitated, and it was possible to prevent the calcium absorption efficiency from decreasing. In addition, when the pH of Examples 1 and 2 was adjusted to further increase with an aqueous sodium hydroxide solution, white turbidity occurred and precipitation began to occur when the pH reached 7.60. Examples 1 and 2 in which the pH was adjusted to 8.2
The calcium content was measured in the filtrate of the solution. Table 1 shows the measurement results of the calcium content and the calcium dissolution rate calculated based on the measurement results. It is confirmed that in Examples 1 and 2 using a citric acid solution, a high calcium dissolution rate is maintained even when the pH is adjusted to 8.2. In addition, when the pH of various nutritional drinks and nutrient-containing soft drinks marketed as drinks was measured, the results shown in Table 2 were obtained. PH of drink preparation
There is no significant difference in pH from the calcium replenishment solutions of Examples 1 and 2, and it is confirmed that there is no problem in using the calcium replenishment solutions as part of the raw materials for drinks.
