Abstract

PURPOSE:To obtain drinking water for preservation food usable simply and safely, by sealing water in a packing container composed of a plastic film and throwing a pack of a preservative, wherein granular coral sand is coated with silver, in said container. CONSTITUTION:Desalted coral sand is activated by heating to be immersed in an aqueous solution of silver and ammonia. After said solution is sufficiently penetrated in the coral sand, glucose is added to the solution as a reducing agent to allow the solution to stand for about 10-20hr to perform the coating of silver. Subsequently, the solution is heated under reduced pressure to be evaporated to dryness and the residue is further dried at about 50-80 deg.C for about 3-5hr to obtain a preservative 4. This preservative is received in a water resistant water-permeable packing container composed of synthetic paper or synthetic fiber to form a pack 5. Keepable food (or beverage) 2 is sealed in one of of the cavities of a packing container 1 composed of a plastic film and water 3 having the pack 5 thrown therein is sealed in the other cavity thereof. By this method, since sterilized water can be always preserved by utilizing the packing container of the preservation food, this system is extremely convenient.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a simple and convenient preserved drinking water that can be safely used for eating, drinking, and preparing preserved foods or portable foods.

[Conventional technology and problems]

Preserved foods that are prepared for emergencies such as earthquakes generally require water for cooking, with the exception of so-called I/) Ruto foods and ■, 5 foods. In addition, portable food, which is convenient for mountain climbing and camping, can usually be prepared using clear water from springs in each state, but it is not always possible to obtain safe and delicious water due to contamination with harmful substances.

Therefore, if you can always store various preserved foods and drinks in a form with clean water in an amount suitable for cooking or eating, you will be completely safe against unexpected disasters.
You can eat and drink with peace of mind while mountain climbing or camping.

The present invention was made in response to the above-mentioned demands.
The purpose is to provide preserved edible drinking water that can be used simply and safely by combining it with preserved foods and drinks.

[Means and effects for solving the problem] Invention 9 Preserved edible drinking water is obtained by sealing an appropriate amount of water in a packaging container such as a plastic film, and putting a bag containing a preservative into the container. Features.

By attaching the preserved edible drinking water according to the present invention next to the packaging container that completely seals the food or drink,
You can always use safe, clean water to cook or prepare food or drinks on the 4th floor, eliminating the hassle of looking for water or worrying about running out of water during emergencies or vacations, giving you peace of mind. Furthermore, by adjusting the amount of preserved edible drinking water to the optimum amount for cooking and blending the preserved foods and beverages that are packaged together, it is possible to always eat and drink in the most delicious state.

(Example〕 Hereinafter, the present invention will be explained based on the drawings.

In Fig. 1, 1 is a completely sealed packaging container made of paper, aluminum foil, polyethylene, polyester, etc. sheets either singly or laminated. 2 is enclosed, and water 3 is enclosed in the other side.
is included.

Preserved foods 2 include single or mixed grains such as washed and dried rice, barley, beans, and corn, powdered beverages such as instant coffee, powdered milk, and powdered juice, and alcoholic beverages such as whisky, sake, and shochu, which can be stored at room temperature. Any food suitable for preservation can be sterilized and sealed.

Water 3 is sealed in an amount suitable for cooking the above-mentioned preserved food, such as washed rice.

Then, a bag 5 containing a preservative 4 is added to the water 3. This preservative has a bactericidal ability that can withstand long-term storage, and has the effect of making water slightly alkaline.
0.0% to activated activated granular coral sand that contains virtually no salt. Those coated with 1-5% by weight of silver are preferred.

By adding this preservative, the silver adhering to Corral Sand gradually becomes cations and elutes, exhibiting a bacteriostatic or sterilizing effect. Iwata uses coral sand, which contains trace amounts of natural ingredients such as phosphorus, to create a slightly alkaline mineral water.

In order to produce the above-mentioned preservative, reef-building corals are ground into coral sand having a particle size of 10 to 50 mesh, and thoroughly washed until it is substantially free of salt.

Next, the desalted corral sand was heated to 20 mmHg ~
Inert gas (nitrogen or argon) reduced to 50 Hg
Activation is performed by heating at 200 to 400 °C in an atmosphere of 2 to 4 hours to decompose the attached organic components and develop the pores of the coral sand.

Next, a silver coating is applied. This is done by immersing Corral Sand in a silver ammonia aqueous solution prepared by adding ammonia water to a silver nitrate aqueous solution at 20 to 40°C under reduced pressure, allowing it to fully penetrate, and then adding glucose as a reducing agent.
Let stand for 20 hours. As a result, the silver ions adsorbed on the surface or internal surface of Coral Sand are reduced and become metallic silver.

After finishing silver coating, further under reduced pressure 200~400℃
The product is heated to 50°C and evaporated to dryness, then washed until no silver nitrate is detected, and finally dried at 50-80°C for 3-5 hours to serve as a preservative.

The amount of silver deposited is in the range of 0.1 to 5% by weight, preferably 0.2 to 3% by weight, and 3μ
The coating should be able to be coated to a thickness of about 1.5 m.

The preservative 4 thus produced is placed in a water-resistant and water-permeable packaging container made of synthetic paper or synthetic fiber to form a bag 5. The amount of preservative 4 is 3 to 2 per 11 parts of water.
A small amount of about 0g is sufficient. Also effective is a mixture of Preservative 4, which is made by coating Corral Sand with silver, and Corral Sand, which is not coated with silver, in a ratio of 1 to 1:5 (volume ratio). As a result, even more delicious water can be obtained without inhibiting the water's sterilizing effect.

As explained above, according to the present invention, sterilized water can be stored at all times by using a packaging container for preserved foods, so it is convenient for cooking rice and other foods. It can be safely used in the preparation of coffee and milk, or in diluting alcoholic beverages with water, and is extremely convenient as a preserved food in emergencies or as a form of food during excursions such as mountain climbing and camping.
