Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soft drink using deep ocean water taken from a seabed at a depth of 200 m or less, a method for producing the same, and a system for producing the same.

[0002]

2. Description of the Related Art In recent years, deep ocean water has been receiving attention.
This deep sea water is seawater taken from the seabed at a depth of 200 m or less, and has very little organic matter in the seawater and is very clean. Further, the water temperature is as low as 10 ° C. or less, and many trace elements are contained.

[0003] Various soft drinks using the deep sea water are also commercially available. These are mineral water,
There are, for example, a mixture of about 1 to 5% of deep sea water from which salt has been removed, and a mixture of vitamin and fruit juice.

[0004] These soft drinks have become popular products among health-conscious consumers because the deep ocean water is less contaminated and rich in minerals.

In Japanese Patent Publication No. 7-34728, a soft drink using deep ocean water is disclosed. This soft drink is prepared by mixing deep sea water taken from deep sea with a depth of 200 m or less with drinking water in an untreated state without performing any physical or chemical treatment other than filtration.

[0006]

The greatest reason why soft drinks using such deep ocean waters have attracted attention is that abundant minerals are the most suitable products for health consciousness.

However, as described above, the removal of salt or the addition of vitamins and fruit juices will destroy the original mineral balance of deep sea water.

[0008] Minerals are trace elements and do not need to be contained in large amounts. If they are contained more than necessary, the mineral balance in the human body may be disturbed, which may have a negative effect.

As is said that the mineral balance in seawater is very similar to the mineral balance in human body fluids, it is desirable to make a soft drink while maintaining the natural mineral balance.

Japanese Patent Publication No. 7-34728 is characterized in that it is mixed with drinking water as it is without performing any other than ordinary filtration, and is a preferable soft drink in terms of mineral balance.

[0011] However, when deep sea water is present at a temperature of 10 ° C or less in the deep sea where the sun's rays do not reach, there is little propagation of microorganisms, but if it is withdrawn and stored on the ground, The water temperature also rises, and in abundant minerals, the environment becomes suitable for the growth of microorganisms.

[0012] For this reason, when used in a soft drink as it is, there arises a problem that water quality control, especially bacterial control, must be thoroughly carried out.

[0013] The present invention has been made in view of the above-mentioned problems, and it is possible to prevent the mineral balance of deep ocean water and suppress the growth of bacteria in the deep ocean water, thereby ensuring safe and healthy health. An object of the present invention is to provide a soft drink using deep sea water that is good for promotion, a method for producing the same, and a system for producing the same.

[0014]

In order to solve the above-mentioned problems, the present invention provides a refreshing mixture of pure water obtained by subjecting drinking water to ion-exchange treatment and deep ocean water filtered to about 0.01 micron. Drinking water. The mixing ratio was such that the deep sea water was 0.2 to 1.0% by volume.

The deep sea water is seawater taken from a depth of 200 m or less, and is different from surface water in that it is clean, has few bacteria, and has a good mineral balance. Pure water obtained by subjecting drinking water to ion-exchange treatment is generally used as pure water in the beverage industry, and removes impurities by coagulating and filtering drinking water such as tap water, and removes mineral components with an ion-exchange resin. And it is pure water obtained by removing chlorine by activated carbon treatment, and its hardness is almost zero.

[0016] By filtering the deep sea water to about 0.01 micron, bacteria and viruses can be removed, bacteria contaminating during storage and from pipes can be removed, and used together with heat sterilization. Thereby, safe soft drink can be obtained.

FIG. 3 is a diagram showing the relationship between various filtering methods, their filtering accuracy, and the object to be removed. Bacteria and viruses can be removed at 0.01 micron (10-1 μm)
This shows that the method can be realized by the microfiltration (MF) method.

By using pure water from which mineral components have been removed and adjusting the mixing ratio of the deep sea water to 0.2 to 1.0 V%, the mineral balance of the deep sea water can be maintained without losing its mineral balance, and it is delicious. Can be drunk.
If it is 0.2% or less, it is completely tasteless, close to pure water itself, and does not have the unique taste of water. If it is 1.0% or more, it becomes salty. When it is 0.2 to 1.0 V%, the hardness becomes about 20 to 40, and the water is easy to drink and delicious.

Further, according to the present invention, the deep ocean water is
Soft drinks are prepared using concentrated deep seawater that has been concentrated to 0 to 80%.

The concentration increases the salt concentration,
Preservability increases. The deep sea water is usually pumped up from a deep sea below 200 m by a water intake device, stored in a tank, and the stored deep sea water is transported by a truck or the like and sent to a soft drink manufacturing plant or the like.

For this reason, sufficient sanitary management is required during the transportation and storage period from the intake to the drinking water.
In order to take advantage of one of the major characteristics of deep ocean water, that is, it is low in bacteria and clean, management during transport and storage is important. Dramatically improved.

Further, the present invention provides a filtration step of filtering deep sea water to about 0.01 μm, and a method of filtering the deep sea water filtered and pure water obtained by ion-exchanging drinking water with a predetermined ratio. And a system for producing a soft drink having a sterilizing step of heating and sterilizing the mixed solution having passed through the mixing step.

In a 0.01 micron filtration step, bacteria are removed while leaving mineral-dissolved ions in the deep sea water, and mixed with pure water from which the mineral components have been removed in a mixing step, The beverage is manufactured by heat sterilization in a sterilization process.

The filtration step may be any one capable of performing a filtration treatment down to about 0.01 μm. It can be realized by performing a filtration treatment using a microfiltration method (MF method), which is a general membrane treatment technique. By this filtration, bacteria are removed, but minerals dissolved in deep sea water remain. Further, since the bacteria are removed, the heating time can be minimized in the sterilization step, and an effective sterilization treatment can be realized.

As the sterilizing means, highly reliable heat sterilization is used. Although other sterilization means can be used, it is necessary to perform sterilization treatment surely in a short time. Therefore, it is desirable to use heat sterilization means.

As a means for mixing the deep sea water and the pure water, a mixing tank provided with a mixing device such as a stirring blade generally used for mixing liquids can be used.

[0027] The present invention further comprises a concentration step of concentrating the filtered deep sea water to 60 to 80%.

In the enrichment step, the deep ocean water is reduced to 60-80%
Concentration increases the concentration of salt in deep ocean water, enhances preservability, reduces capacity, and reduces transportation costs. Of course, in the concentration, the concentration is performed while maintaining the mineral balance.

As the concentration means, a reverse osmosis membrane (RO membrane) apparatus which is a separation apparatus using a reverse osmosis membrane having the highest separation performance among membrane separation techniques can be used. In this concentration method by the reverse osmosis membrane method, as shown in FIG.
(0.0001 microns), and can be concentrated without disrupting the mineral balance of deep ocean water.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a schematic flow chart showing a method for producing a soft drink using deep ocean water according to the present invention. In the present embodiment, a soft drink using deep sea water taken from a depth of 340 m near the sea in Okinawa Prefecture and pure water obtained by subjecting tap water to ion exchange treatment.

S-1) In the first filtration step, the taken deep sea water 1 is filtered to about 1 micron using a filter filtration device or the like. In this first filtration step, fine particles such as impurities and main bacteria such as Escherichia coli are removed.

S-2) Next, in the second filtration step, filtration is further performed to about 0.01 μm. Here, a filtration treatment is performed by a filtration membrane technique using a microfiltration method (MF method).

At this stage, even fine bacteria and viruses can be removed. However, for various mineral ions dissolved in deep ocean water, their particles are even smaller, ranging from 1.0 nm (0.001 micron).
0.1 nm (0.0001 micron) and is left unremoved.

S-3) Next, in the concentration step, the above mineral components are concentrated. The concentration treatment is performed by a membrane separation technique using a reverse osmosis method (RO method).

S-5) Next, in the mixing step, the deep sea water filtered and concentrated, the pure water 2, and the additive material 3 such as vitamins or natural flavors are mixed in a stirring tank.

In this case, the depth of the deep sea water is 0.2-1.
Mix to about 0%. The mixing ratio is preferably such that the unique taste of natural water such as mineral water due to the mineral content of the deep ocean water is felt, and 0.4
About 0.6% is more preferable. If the mixing ratio is high, the water becomes salty due to the salt content of the seawater, the hardness increases, and the water does not become delicious.

It is important that the mineral content is contained in a well-balanced manner, and that it is not preferable that the content is too large. Since pure water from which minerals have been removed is used, the balance can be maintained as it is without breaking the mineral balance of deep ocean water.

S-6) Next, heat sterilization is performed. Heating is performed at 135 ° C. for 30 seconds.

S-7) Filter with a line filter of about 1 micron.

S-8) A bottling process for filling a PET bottle or the like is performed to obtain a soft drink product.

Next, an embodiment of a soft drink production system using deep sea water and pure water obtained by ion-exchanging drinking water will be described in detail with reference to the drawings. FIG. 2 is a schematic process diagram showing the manufacturing process.

The deep sea water 1 taken from the seabed at a depth of 340 m is transported and stored in the deep sea water tank 4.

1) First, the water is sent from the deep ocean water tank 4 to the filter filtration device 5 by a water supply pump.
Filter through an approximately 1 micron wound filter. As the thread wound filter, a depth filter manufactured by Loki Techno Co., Ltd. having a filtration accuracy of 1 micron was used.

2) Next, it is sent to the microfiltration device 6 and
Filter to about 1 micron. As the microfiltration device 6, a hollow fiber membrane module of an external pressure type total filtration system manufactured by Toray Industries, Inc. was used. The pore diameter on the membrane surface was 0.01 μm.

3) The deep sea water filtered to 0.01 μm is sent to the reverse osmosis membrane concentrator 7 by a high pressure pump, where a 70% concentration treatment is performed. The osmosis membrane concentrator 7 has a performance of 99.4% salt rejection.
A low-pressure type reverse osmosis membrane element using a polyamide-based composite membrane manufactured by Nippon Kayaku was used.

4) The concentrated deep seawater concentrated in the above concentration step is stored in the concentrated water tank 8.

In parallel with the above-mentioned filtration and concentration of deep sea water, pretreatment of pure water in which tap water was ion-exchanged in advance was performed.

5) From the pure water tank 9, the water is sent to the filter filtration device 10 by the water pump. The filter filtration device 10 was a roll-type depth filter manufactured by Loki Techno Co., Ltd. and used a filter having a filtration accuracy of 10 microns.

6) The above-mentioned filtered and concentrated deep-sea water, pre-treated pure water, and raw materials 11 such as vitamins and natural flavors are sent to a mixing device 12 and mixed with stirring. It was blended so that the deep sea water would be 0.3-0.5%. The mixing device 12 used a rotating blade type stirring tank.

7) The mixed liquid was sent to the heat sterilizer 13 and sterilized by heating. As the sterilizer 13, a UHT sterilizer was used. Sterilization conditions are equivalent to 135 ° C. for 30 seconds.

8) After the sterilization treatment, the mixture was filtered with the line filter 14. The filter used a 250 mesh strainer.

9) After the filtration treatment, PET bottles were filled by the bottling device 15. The filling temperature is 85 ° C,
After filling, the beverage was cooled to 40 ° C. or lower to obtain a soft drink in a PET bottle.

In this embodiment, the plastic bottle is filled, but it may be filled in a glass bottle or a product in a can.

Further, auxiliary materials such as fruit juice and carbonic acid may be blended. In that case, it is preferable to mix in advance the pure water obtained by subjecting the drinking water to ion exchange treatment and the deep sea water, and additionally mix the auxiliary raw materials. In a state where the deep ocean water is dense, some auxiliary materials may be suspended due to a redox reaction.

In the filtration step, a method other than the above-mentioned filtration treatment may be used as long as the filtration accuracy is increased stepwise and finally filtration treatment to about 0.01 μm can be performed. In consideration of the above, a multi-stage configuration is desirable, and an ultrafiltration membrane using a polymer membrane may be used. A chemical adsorption filter or the like is not preferable because it involves the adsorption of mineral components.

The separated water separated in the concentration step is very clean and can be used as back-washing water, and can also be used as medical water or drinking water as ultrapure water.
