PURPOSE:To obtain a preservative which can be widely used for purification and prevention of rotting of drinking water and preservation of various processed or perishable foods by mixing glauconite with germanium. CONSTITUTION:A preservative containing as active ingredients glauconite and germanium in an amount of 0.004-0.005wt.% based thereon. Glauconite is a multi-element mineral comprising a specific metamorphite wherein chlorite, hornblende, apatite, etc., congregate, mainly comprises silicic acid and contains potassium, sodium, calcium, alumina, and various transition metal elements such as iron, nickel, chromium, cobalt, vanadium, etc. It is known that a trace amount of germanium has a pharmacological effect on diseases such as cancer, skin diseases, etc. When this preservative is used for drinking water, it prevents the water from rotting, thus not only making the water storable for a long period of time but also converting the water into a weakly alkaline good mineral water, and it keeps foods such as perishable vegetables, fishes, shell-fishes, etc., fresh for a long period of time.

Description

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

[Conventional technology]

In general, tap water retains a chlorine odor due to purification and sterilization, and its unpleasant taste has been pointed out. In addition, even if you store it in a sealed plastic container in case of an emergency such as an earthquake, it 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, dedroacetic 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.

[Problem 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 chemical compounds, and many of them are toxic and require specialized knowledge.Also, like the silver-based preservatives mentioned above, their use is limited, and the general public is not allowed to use them. It is difficult to use for people.

The present invention has been made focusing on such problems,
Our objective is to provide a preservative that can be widely used to purify drinking water, prevent spoilage, process various types of food, and preserve fresh foods, is easy to use, and is safe for anyone to use. [Means for Solving the Problems] As a result of intensive studies to solve the above problems, the inventor of the present invention has developed a method of adding naturally occurring Ioh stone and a small amount of germanium to tap water in the form of granules or powder. This not only eliminates the chlorine odor and provides delicious mineral water, but also does not cause spoilage even during long-term storage, and can be stored for long periods by spraying or immersing fresh vegetables and fish and shellfish in the aqueous solution. They discovered this and completed the present invention.

That is, the present invention uses Io stone and 0.000% for Io stone.
The preservative is characterized by containing 4 to 0.005% by weight of germanium as an active ingredient.

Iōseki is a multi-element mineral consisting of a special aggregation of chlorite, amphite, apatite, etc. As shown in Table 1, it is mainly composed of silicic acid (including soluble silicic acid), potassium, sodium, and calcium. , aluminum, 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 a pulp crusher
The material ground for 5 minutes has a large specific surface area of 277.5 m'/g (measured by BET method). It is known that small amounts of germanium have pharmacological activities effective against diseases such as cancer and skin diseases. Iao stone and a small amount of germanium as preservatives can be used in various forms, such as by sintering or molding the fine powder into a plate shape or pellet shape, or by partially dissolving the fine powder in water, or by suspending it. It can also be used cloudy. To deodorize, purify and prevent spoilage of tap water, well water, etc., add the above-mentioned fine powder or pellets etc. to the water,
Just leave it for ~4 hours. In addition, to obtain the instant effect, it is also possible to add 0.1 to 0.3 microns of fine powder of about 500 to 1000 mesh to 100 g of water, stir, and drink it as is. To preserve fresh vegetables, fish and shellfish, and meat, spray purified water preservative-treated with the preservative of the present invention on these items, or soak them once and store them in the refrigerator, or use polyethylene, polyvinyl chloride, etc. 5 plastic films in advance
A film may be formed using a blend of 00 to 1500 mesh fine powdered Iao stone and germanium, the food may be packaged and sealed in the film or container, and then refrigerated.

[Effect]

The preservative according to the present invention effectively contains Iōseki and a small amount of germanium. As mentioned above, Iōseki is porous and has a large specific surface area, so it exhibits excellent adsorption ability and absorbs chlorine, organic matter, and microorganisms in water. It absorbs and purifies harmful substances. 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 generated by decomposition, and also inhibits the growth of spoilage bacteria (anaerobic bacteria), thereby preventing drinking water from spoiling. Further, a small amount of germanium acts as a co-catalyst that strengthens the catalytic action of the transition element, thereby increasing the antiseptic effect.

Furthermore, Iou stone contains a well-balanced mineral component that is essential for living organisms, and contains a considerable amount of soluble silicic acid, making it slightly alkaline, so when it is added to water, the water becomes alkalized and delicious ξneral water is obtained. ．． In addition, since it contains many metal elements and has strong inter-element 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 deodorized, purified and preservative treated water or a suspension containing Io Stone, these foods will be Because harmful substances attached to the food are removed, the food can stay fresh for a much longer period of time 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 spoilage prevention and long-term storage stability of tap water, pellets and grains 3 were made into 5 x 5 x 51 liters of tap water 11 from a fine powder mixture of Iou stone and 0.005% by weight germanium. 50g of ~Low natural zeolite was added to each and stored in a 5L plastic tank with a stopper.
(no treatment).

The results are shown in Table 2. ．． Table 2 (Unit: ■/j!) 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, the preservative of the present invention prevents water from rotting in the same way as natural zeolite, but the chlorine concentration in water is low, the ξneral component (hardness content) is abundant, and the pH
It is also slightly alkaline and can be stored for long periods as delicious mineral water.

In addition, this long-term storage water contains general bacteria (100/1 or less).
It also met water quality standards such as coliform bacteria (not detected).
