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).

Claims

1. A seawater mineral component-containing composition obtained by subjecting seawater to electrodialysis, said seawater mineral component-containing composition having a sodium concentration of 6 mg/L or less when adjusted to form an aqueous solution having a hardness of 100 (EDTA method).

3. The seawater mineral component-containing composition according to claim 1, having a magnesium concentration of 20 mg/L or more when adjusted to form an aqueous solution having a hardness of 100 (EDTA method).

4. The seawater mineral component-containing composition according to claim 1, having a magnesium/calcium weight ratio (Mg/Ca) of 4 or higher.

5. The seawater mineral component-containing composition according to claim 1, wherein said seawater is deep seawater.

6. The seawater mineral component-containing composition according to claim 5, wherein said deep seawater is seawater at a depth of 200 m or more.

7. The seawater mineral component-containing composition obtained by subjecting seawater to electrodialysis according to claim 1, wherein said electrodialysis is performed, using a monovalent cation-selective dialysis membrane, until an electric conductivity of less than 10 mS/cm is reached.

8. The seawater mineral component-containing composition obtained by subjecting seawater to electrodialysis according to any one claim 1, wherein said electrodialysis is performed a plurality of times.

9. The seawater mineral component-containing composition according to claim 7, wherein in said electrodialysis, a sodium concentration in a concentration compartment is maintained low.

10. A food or beverage containing the seawater mineral component-containing composition according to claim 1.

12. The seawater mineral component-containing composition according to claim 8, wherein in said electrodialysis, a sodium concentration in a concentration compartment is maintained low.

2. A seawater mineral component-containing composition obtained by subjecting seawater to electrodialysis, said seawater mineral component-containing composition having a sodium concentration of 4 mg/L or less when adjusted to form an aqueous solution having a hardness of 100 (EDTA method).

11. The seawater mineral component-containing composition according to claim 2, having a magnesium concentration of 20 mg/L or more when adjusted to form an aqueous solution having a hardness of 100 (EDTA method).
