Description

[Detailed Description of the Invention] This invention utilizes marble and limestone, which have radiation, in order to preserve the freshness of most general food packaging materials. , magnetite, monazite, etc. are crushed into a powder of 100 mesh or less, mixed and masticated with the addition of a chemical freshness-preserving agent, or dispersed in an adhesive and dried. Also, cloth, paper other than synthetic resin,
Woven and non-woven metal films can be coated and used as exterior materials for foods, especially processed marine products, processed livestock products, vegetables, fruits, flowers, drinking water, pharmaceuticals, cigarettes, feed, etc. The aim is to develop packaging materials for plastic films, paper, non-woven fabrics, woven fabrics, leather, rubber, and processed metal foil products that are processed to maintain their freshness for a long period of time.

Generally known freshness preserving agents include metal reduced iron powder, small bags containing alcohol, oxidizing agent, etc. are placed in food containers to coexist with food to maintain freshness.However, metal reduced iron powder This was a method of preserving freshness through its deoxidizing effect during use, but there were problems with storage, and most of it turned into iron oxide before use, and the deoxidizing reaction was extremely slow.

Also, to prevent spoilage caused by bacteria and to preserve freshness, alcohol microcapsule powder can be used to preserve sausage ham,
It is used for fish such as kamaboko, but its effectiveness is extremely short and it becomes less effective after 30 hours. Many things are used to keep things fresh,
Many things have become problematic in terms of toxicity from the Ministry of Health and Welfare.

Therefore, it was necessary not only to reduce the amount of application of such chemicals to render them harmless, but also to maintain effective freshness for a long period of time.

Therefore, the present application uses limestone, marble, magnetic jadeite, and monazite powder that have radiation, and uses extremely low natural radioactivity to reduce the aforementioned jadeite, which has radiation that is 1.2 to 1.7 times higher, to 100 mesh or less. The pulverized powder is mixed with a freshness-preserving agent, a surfactant, etc., and then mixed with plastics such as vinyl chloride film, pelletized at room temperature, and then made into a film using a stone roll. Furthermore, when a film is made by mixing polyethylene, polypropylene, or polyethylene vinyl acetate with the gemstone powder, a film with radiation is formed. When putting sausages and fish meat paste into this film, there is a slight discoloration, especially the black color of raw meat, which is produced by dipping stone water with a lot of carbonate ion radiation, and when pre-treated, the color changes in about 3 days. It is possible to prevent discoloration of items that turn black for 7 days or more.

When this is packaged with a film containing gemstone powder and a freshness-preserving agent, the radiation of gamma rays and β-rays further prevents discoloration, maintains the freshness of the meat color for a long period of time, and increases the product value.

In addition, when vegetables and fruits are similarly treated with jade stone water and pretreated with carbonated radiation water and packaged with a mixed film of radiation jade stone and freshness-preserving agent powder, the same results as described above are obtained.

In addition, when laminating a radiation film with a film containing a freshness-preserving agent, an antifungal agent, and a disinfectant, the freshness of the film can be maintained for a longer period of time. When mixing iron, iron tartate, iron malate salt, or the foaming agent Difdu dye, the former is acidic and generates carbon dioxide gas, which progresses the deacidification of the food inside the package and causes damage due to oxidation. It suppresses deterioration of freshness and prevents discoloration and preserves freshness through radiation action. For example, when diazo dyes interact with limestone and jadeite powder, nitrogen gas is generated through catalytic decomposition, which replaces oxygen in the packaging. Rather, it takes 7 to 10 days to develop, and the radiation effect further extends its freshness.

In order to dissipate more of these gases, it becomes more active when using a porous film such as polyurethane, and by making one side of the inner surface unilaterally porous, more effective and efficient gas generation can be achieved. be done.

In addition, when coating synthetic leather, polyurethane foam, paper, non-woven fabric, metal film, rubber, etc., by using a radiation effect and a freshness-preserving agent in combination, you can not only obtain the same result, but also reduce the radiation effect. When placed in shoe insoles, it increases heat retention and is used for other purposes, such as preventing athlete's foot. In addition, this radiation action allows the radiation of gamma rays and beta rays to penetrate well into the object, thereby preventing bactericidal properties and discoloration, making it suitable for long-term storage.

The milky-white film made by mixing this gemstone powder and a freshness-preserving agent with a vinyl chloride resin film exhibits its preservative effect more clearly through post-treatment with alcohol and salicylic acid Sumatel, so it can be used in drinking water, alcoholic beverages, etc. It is useful as an exterior packaging material for canned foods and as an aromatic film.

In addition, when using Shislak emulsifier, coaric acid ester emulsifier Monopolyne, and ammonia water as a brightening agent and maintaining the freshness of tangerine fruit, when adding this jadeite powder radiation to a mixed paper freshness-keeping agent, the gloss will remain even after 6 months. The result is that the freshness does not change.

In addition, this radiation jade stone powder mixed film is used in many ways to maintain freshness as a deacidifying agent when adding reduced iron powder, unreduced potassium nitrite soda or sulfite soda powder, or calcium salt.

In addition, products mixed with alcohol microcapsule powder or aromatic microcapsule powder and coated with the above-mentioned jade stone powder or masticated have the effect of increasing sterilization properties and increasing commercial value due to their aromatic properties. . In this way, this invention is a paper in which a powder containing a combination of marble, limestone, porcelain, and reduced iron freshness-preserving agent with radiation is mixed into a plastic film or dispersed in a binder and applied. Using non-woven fabric, woven fabric, leather, metal film, sponge perforated plate,
Due to its radiation and the effect of freshness-preserving agents,
It is used as an exterior material for foods, clothing, alcoholic beverages, drinking water, etc., and is used to purify water for cultured fish, so it is industrially useful as a multipurpose long-term preservation product to maintain freshness.

The implementation of this invention will be explained as follows with reference to the drawings.
