Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a preservative that is effective for purifying drinking water and preventing spoilage, and for preserving processed foods, fresh vegetables, fish and shellfish, and the like.

[Conventional technology]

In general, tap water retains a chlorine odor due to purification and sterilization, and its unpleasant taste has been pointed out. Furthermore, even if they are stored in sealed plastic containers in preparation for emergencies such as earthquakes, they may rot during long-term storage and become useless.

Activated carbon and granular calcium carbonate coated with silver are known as deodorizing and preservatives for drinking water.

On the other hand, benzoic acid, sorbic acid, dehydroacetic acid, and their salts or derivatives are approved for use as food additives in processed foods such as soft drinks, alcoholic beverages, and fish meat.

(Problems to be Solved by the Invention) Conventional antiseptic and purifying agents that combine silver with activated carbon or granular calcium carbonate use silver, which is a precious metal, and are therefore expensive and economically disadvantageous.

In addition, various food additives are chemically synthesized products, and many of them are toxic and require specialized knowledge.Also, like the silver-based preservatives mentioned above, their use is limited, and they are not commonly used. It is difficult for people to use.

The present invention has been made focusing on such problems,
An object of the present invention is to provide a preservative that can be widely used for purifying drinking water, preventing spoilage, and for various processing or preserving fresh foods, is easy to use, and can be used safely by anyone.

[Means for Solving the Problems] As a result of intensive studies to solve the above problems, the inventors of the present invention found that when naturally occurring Io Stone is added to tap water in the form of granules or powder, the odor of chlorine is eliminated. It has been discovered that not only can delicious mineral water be obtained, but also that it does not spoil even during long-term storage, and that fresh vegetables, fish and shellfish can be stored for long periods of time by being sprayed or immersed in the aqueous solution, and the present invention has been made. I was able to complete it.

That is, the present invention resides in a preservative characterized by containing Iao stone as an active ingredient.

Iōseki is a multi-element mineral consisting of special metamorphic rocks such as chlorite, amphibite, and apatite. In addition to iron, nickel,
It contains many transition metal elements such as copper, manganese, chromium, cobalt, and vanadium.

Table 1 (Analysis by Light Industry Bureau, Ministry of International Trade and Industry) In addition, like activated carbon and zeolite, Iou stone is highly porous. 1 with an agate crusher
The material ground for 5 minutes has a large specific surface area of 277°5 m''/g (measured by BET method).

Io stone as a preservative can be used in various forms such as lumps, granules, powder, or fine powder sintered into plate or pellet shapes, or by partially dissolving the fine powder in water, or ! It can also be used with AA clouded.

To deodorize, purify, and prevent spoilage of tap water, well water, etc., add Io stone crushed to about 3-1Qmm to the water and add 2-4
Just let it sit for a while. In addition, in order to obtain the effect immediately, it is also possible to add about 500 to 1000 mesh of fine powder to 100 g of water in a range of 0.1 to 0.3 cm, stir, and drink as is.

To preserve fresh vegetables, fish, shellfish, and meat, spray purified water that has been preservative treated with Io-seki, or soak it in the refrigerator and store it in the refrigerator, or store it in a refrigerator such as polyethylene, polyvinyl chloride, etc. Plastic film in advance from 500 yen
A film may be formed using a blend of 1,500 mesosi powder of Iao stone, the food may be wrapped and sealed in the film or container, and then refrigerated.

[Function] The preservative according to the present invention contains Iao stone as an active ingredient. As mentioned above, Iao stone is porous and has a large specific surface area, so it exhibits excellent adsorption ability and absorbs harmful substances such as chlorine, organic matter, and microorganisms in water. Adsorbs and purifies ingredients.

In addition, since it contains many transition elements with d-orbital electrons, the adsorbed organic matter is oxidized and decomposed by its catalytic action.
It efficiently adsorbs and removes ammonia and methane gas produced by decomposition, inhibits the growth of spoilage bacteria (anaerobic bacteria), and prevents drinking water from spoiling.

Furthermore, Iou stone contains a well-balanced mineral component that is essential for living organisms, contains a considerable amount of soluble silicic acid, and exhibits weak alkalinity, so when it is added to water, the water becomes alkalized and delicious mineral water can be obtained.

In addition, since it contains many metal elements and has strong elemental affinity, harmful heavy metals such as cadmium and mercury are adsorbed and immobilized, making it possible to obtain pollution-free water.

Therefore, if foods such as fresh vegetables, meat, fish and shellfish are washed or immersed in water that has been deodorized, purified and preservative treated, or in a suspension containing Io Stone, these foods will be removed. Because harmful substances adhering to food are removed, food can stay fresh for much longer than by regular refrigerated storage.

(Example) Hereinafter, the effects of the preservative according to the present invention will be specifically explained with reference to Examples.

Example 1 In order to test the corrosion prevention and long-term storage stability of tap water, 50 g each of Iao stone and natural zeolite with a particle size of 3 to 10 mm were added to 1 p of tap water, and the samples were stored in a 5 p plastic tank with a stopper. treatment).

The results are shown in Table 2.

Table (Unit ■/β) ND = Not detected, when measured by a method specified in a ministerial ordinance, the result is below the quantification limit of the method.

As is clear from Table 2, Iōseki prevents water from spoiling in the same way as natural zeolite, but the chlorine concentration in the water is low, it is rich in mineral components (hardness), and the pH is slightly alkaline. It can be stored for a long time as delicious mineral water.

This long-term stored water also met water quality standards such as general bacteria (100/1 m1 or less) and coliform bacteria (not detected).
