JPH09220A - Treatment of dried sea weed - Google Patents

Abstract

PURPOSE: To desalt a dried sea weed almost without discharging useful contained components such as iodine, etc., by cleaning the dried sea weed with salt water having the same hydrogen ion concentration as that of sea water. CONSTITUTION: A dried sea weed is washed with salt water having the same hydrogen ion concentration (pH2-3) as that of sea water. Salt water attached to the sea weed is washed away with fresh water and immersed again in salt water to remove salt. These operations are repeated for six to eight times to remove only salt, to leave most of useful components such as iodine, etc., and to slightly remove a coloring matter.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for treating dried seaweed which can be used in health foods, cleaning cosmetics and the like.

[0002]

2. Description of the Related Art Seaweed contains many useful components for health such as iodine, carotene, protein, iron, calcium and dietary fiber. Among them, iodine also has wetting, activating and antibacterial properties. . Therefore, seaweed is useful not only as a health food but also as a cosmetic product for washing soap, shampoo, etc. that is processed and mixed with basic soap, and its reserves are almost unlimited as a marine resource. Is expected to increase.

After landing the highly available seaweed,
In order to obtain the useful products as described above, various processes have to be carried out, and in particular, desalting is the above-mentioned health food for the purpose of reducing the intake of salt, and the cosmetics for cleaning which requires good foaming. It is an essential task for the purpose of use.
In the desalting, if the freshly harvested seaweed is washed with water, the salt content on the surface of the seaweed can be washed off without letting out useful components such as iodine, but usually a large amount of water is landed at one time. It cannot be processed at once. For this reason, most of them must be preserved, but it is very bulky to preserve the seaweed as it is collected, requiring a large storage space for storage.
Further, since it contains a large amount of water and is apt to rot, it requires a large-scale storage facility to maintain a biological environment, which is very uneconomical because of the storage cost.

Therefore, the landed seaweed has a low bulk,
Also, it is dried and stored for long-term storage.
If it is dried and stored, not only does the volume become low, but also the salt content is sufficient due to the evaporation of seawater on the surface of the seaweed, which allows long-term storage.

However, when the dried seaweed is processed into health foods or cleaning cosmetics which require foaming as mentioned above for the purpose of reducing the intake of salt, the salt which has been useful for long-term storage becomes an obstacle. . For this reason, they must be desalted during processing.

[0006]

When desalting is carried out by washing with water, not only salt but also useful components such as iodine will come out.

Therefore, an object of the present invention is to enable a large amount of salt to be removed while desalting dried seaweed while reducing the outflow of useful contained components such as iodine.

[0008]

In order to solve the above-mentioned problems, the first invention according to the present invention is such that the dried seaweed is washed with a salt having a hydrogen ion concentration equal to that of seawater. Of.

A second aspect of the invention is that the desalted seaweed of the first aspect is dried and pulverized into a powder form.

Further, the third invention is that the seaweed desalted according to the first invention is boiled with water to extract the extract.

[0011]

[Function] The hydrogen ion concentration is the hydrogen ion concentration of seawater (= p
When dried seaweed is washed with a water salt equal to (H2-3), iodine in the seaweed does not flow out, but only salt content flows out.

[0012]

EXAMPLE A water salt having a hydrogen ion concentration of pH 2 to 3 can be obtained as a saturated solution obtained by heating salt water in which the weight ratio of water to the salt is 3: 1. In this example, 2
Put 4Kg of water and 8Kg of salt in a pan and put 2
Cook over high heat for ~ 3 hours, cool when saturated, and separate excess salt that has settled to the bottom of the pan from the saturated solution.
This saturated solution has a hydrogen ion concentration (= pH 2
It becomes a salt equivalent to 3).

Next, a hydrous salt prepared by diluting the saturated solution to pH 2 is prepared, and the dried sprouts are alternately immersed in the hydrous salt and fresh water to wash. In this example, the time of soaking in water salt is set to about 5 minutes, during which the sea dust is removed, and when loosened by hand, the salt content in the buds comes off. After this work, take out the sprout from the water salt and soak it in fresh water for about 3 minutes.
Rinse the water salt. This operation of alternately immersing in water salt and fresh water and desalting is repeated about 6 to 8 times, preferably 8 times. In this desalting operation, only the salt content is efficiently desalted, most of useful components such as iodine remain, and the loss of the dye is small, so that the appearance can be maintained in a natural state.

Finally, the desalted bud strains were heated to 9 ° C at 130 ° C.
Dry for 10 hours, reduce bulk, and shape easily for processing.

When the desalted and dried bud strain obtained by the above operation is powdered and analyzed, it is less likely that useful components such as iodine, carotene, protein, iron, calcium and dietary fiber will be impaired, and It has been confirmed that the salt concentration is about one-eighth of the salt concentration before desalting (this analysis is based on the Japan Food Analysis Center Nagoya Branch).

Therefore, it is expected to be a health food with low salt content, and the iodine, which remains in the desalted and dried bud strain, can be used to its wettability, activation and antibacterial properties. It can be added to basic soap at the ratio of and can be used for cleaning cosmetics such as body soap, shampoo and soap. When washed with the cosmetics, it retains moisturizing and is well-suited to rough and rough skin, revitalizing the skin. Also, since it is desalted, it has a good foaming effect.

Furthermore, the extract obtained by boiling this desalted and dried bud strain from water can be used as a food additive.

[0018]

As described above, when the desalination method for dried seaweed according to the present invention is used, desalination can be performed without releasing useful components such as iodine in the dried bud strain, so that the seaweed can be used as a health food or a washing product. It can be used for cosmetics.
