Problems solved by technology

[0012] In order to obtain mineral components rich in calcium or magnesium by electrodialysis, a monovalent cation exchange membrane (monovalent cation selective dialysis membrane) is used to move monovalent cations contained in seawater to the concentration chamber side, so that magnesium, Divalent ions such as calcium remain on the side of the mineral chamber (the above-mentioned dilution chamber), but when the concentration of monovalent cations (mainly sodium) remaining on the mineral chamber side decreases during this operation, the value of the current flowing becomes smaller, the efficiency of electrodialysis becomes worse

Embodiment 1

[0032] Embodiment 1: The manufacture method of secondary mineral water

[0033] Seawater at a depth of 330 m was electrodialyzed using an Asahi Kasei electrodialysis device (SV 1 / 2 type) until the electrical conductivity was 12 mS / cm at the end of electrodialysis to obtain primary mineral water.

[0034] Use an Asahi Kasei electrodialysis device (S3 type) to perform electrodialysis treatment on 500ml of primary mineral water until the conductivity is 8mS / cm or 6mS / cm to obtain secondary mineral water. Table 1 shows the electrical conductivity and changes in main minerals at this time. Asahi Kasei AC120 is used as the electrodialysis membrane for the production of primary mineral water and secondary mineral water. In addition, electrodialysis was carried out at a constant voltage of 15° C. at the initial set temperature, 1.5 mS / cm conductivity at the concentration chamber side, 1.4 L / min circulation flow rate, and 12.5 V voltage.

Embodiment 2

[0036] Embodiment 2: the manufacture method of mineral drink

[0037] The 1st mineral water (12mS / cm) and the 2nd mineral water (8mS / cm, 6mS / cm) described in Example 1 were used with the reverse osmosis membrane SW 30HR-380 (high pressure) SWLE- The second stage of 440 (low pressure) dilutes desalted water (sodium concentration = 1.8mg / L) obtained by processing seawater at a depth of 330m to produce mineral water of various hardness. Table 2 shows the data of the mineral concentration of each hardness at this time.

[0038] Obviously, when electrodialysis treatment of seawater is performed, by making the electrical conductivity low, a composition containing seawater mineral components with reduced sodium concentration and increased magnesium concentration can be obtained.

[0039] In addition, the electrical conductivity reaches 8mS / cm by performing electrodialysis treatment, and when formulated into an aqueous solution with a hardness of 100 (EDTA method), the sodium concent...

Embodiment 3

[0041] Embodiment 3: sensory evaluation of drinking water using 2 times of mineral water

[0042] The sensory evaluation was carried out on the drinking water samples formulated according to Example 2 to have hardnesses of 250, 300, 350, 500, and 1000. The evaluation was conducted by 6 professional evaluators, and the comprehensive evaluation of likes and dislikes and 5 flavor characteristics were evaluated in 5 grades.

[0043] ①In the case of samples whose hardness was adjusted with (12mS / cm) mineral water, they all felt salty and slippery, and when the hardness increased, the bitterness and miscellaneous taste became stronger. Therefore, in the comprehensive evaluation, I don't like it slightly when the hardness is 300, and I don't like it when the hardness is 350. ②In the case of using (8mS / cm) mineral water to adjust the hardness of the samples, the samples with hardness of 250 and 300 did not feel salty, and the overall evaluation was slightly favorable. The sample wit...

Abstract

A seawater mineral component-containing composition is produced which contains mineral components having a good effect on health, such as magnesium and calcium, has a decreased content of sodium, and thus can be used widely for foods. When processed, the seawater mineral component-containing composition provides foods and beverages useful for preventing cardiovascular diseases and lifestyle-related diseases. The seawater mineral component-containing composition is obtained by subjecting seawater to electrodialysis, and has a sodium concentration of 6 mg / L or less when adjusted to form an aqueous solution having a hardness of 100 (EDTA method).

Description

technical field [0001] The present invention relates to a composition containing low-sodium seawater mineral components from seawater and food and drink containing the composition. Background technique [0002] In recent years, due to the Westernization of dietary life or changes in the social environment, the mortality rate of malignant neoplasms (cancer) and cardiovascular disease patients is increasing. The main causes of these factors interact in a complex manner, causing circulatory organ system disorders such as hyperlipidemia, hypertension, and arteriosclerosis with poor blood circulation. [0003] From the perspective of concerns about such lifestyle-related diseases and health intentions, the trend of controlling the intake of sugar and fat components, or actively taking in mineral components from health foods or health foods that are often insufficient due to the widespread use of processed foods has gradually penetrated into the Among general consumers, the healt...
