風味が損なわれる。Traditionally, there has been a demand for delicious water, and famous water from various regions is filled in containers and sold in large quantities. Usually, in this case, the mineral water pumping station and the bottling station are often separated from each other in location, and since they are often stored in a tank after pumping, bacteria are propagated in the mineral water before pumping and bottling. , May proliferate. Therefore, conventionally, chlorine has been added to pumped mineral water to prevent the subsequent reproduction of bacteria (Japanese Patent Laid-Open No. 57-32779). However, it is said that when chlorine is added to mineral water, the natural flavor of the mineral water is impaired and harmful substances such as trihalomethane are generated from residual chlorine. on the other hand,
It has been proposed to treat with activated carbon when chlorine is added, but this method also impairs the natural flavor of mineral water.

ある。In the present invention, after pumping in this way, cooling treatment or this and filtration treatment are applied, and sterilization treatment is carried out by microfiltration of the mineral water which is preferably kept at a low temperature for a suitable period to obtain various bacteria in the mineral water. Is completely removed. Microfiltration can be performed using, for example, a filtration membrane having a pore diameter of 0.22 μm or less. Specifically, a microfilter with a pore size of 0.22 μm is used, and the operating pressure is 1.0 to 2.0, for example.
It is advisable to set the flow rate to about kg / cm 2 and the water flow rate to about 5 to 20 / min.m 2 . According to this method, since the mineral water is not heated at all, the taste does not change, and the original taste of the mineral water can be provided. That is, if a filtration membrane having a pore diameter of 0.22 μm or less is used, all bacteria existing in the mineral water can be efficiently removed, and a sterilizing effect equivalent to high temperature heat sterilization can be obtained.
