Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is an active material whose main functions are antioxidant and filtration ability, and which can be used for various purposes, particularly for food products and food processing. The present invention relates to an animal bone-based active material solidified with animal bone powder as a main component, which is effective for preserving the freshness of materials by preventing oxidation, filtering waste water or used tempura oil, and coagulating materials, and a method for producing the same.

(Conventional technology) Conventionally, for the purpose of maintaining the freshness of food and ensuring its preservability,
Various additives are used, such as preservatives that inhibit the growth of microorganisms and antioxidants that prevent deterioration due to oxidation. For example, preservatives include benzoic acid, sorbic acid, propionic acid, etc., as well as sheets made by sealing activated carbon powder, which has antibacterial properties, in a sandwich shape with synthetic resin film, paper, or woven paper. There were also bags, and paper that was impregnated with water mixed with activated carbon and dried, which were added to food. Antioxidants include ascorbic acid, erythorbic acid, etc., and some are attached to foods for antioxidant purposes, such as bags made by sealing activated iron powder.

On the other hand, filtration of impurities and organic matter in aqueous solutions and air,
Activated carbon, which has an adsorption effect, is used to remove colors and odors.
Tertiary iron oxide and ceramic are used.

(Problems to be Solved by the Invention) However, while the above additives are effective in preserving food, they also threaten the safety of the human body, and some of them have harmful effects such as carcinogenicity and teratogenicity. There is. Bags containing activated carbon or activated iron powder attached to foods have weak preservation or antioxidant effects.

In addition, although activated carbon and tertiary iron oxide have a filtration function, they have a short lifespan and cannot be reused after use.Since ceramics are inorganic, they do not react with organic substances, and, for example, they do not react with organic substances. It did not function satisfactorily as a filtration material for wastewater.

The purpose of the present invention is to solve the above-mentioned drawbacks, to be sufficiently effective in preventing spoilage of food and preserving freshness, to be harmless to the human body, and to prevent ion exchange in water and air, and to eliminate odor. Suitable for adsorption and deodorization, purification of impurities including organic substances, etc.
The present invention also aims to provide an active material mainly made of animal bone, which is a material that can be used for a long period of time, and a method for producing the same.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides an animal bone-based active material obtained by kneading and firing animal bone powder that has been pulverized by firing and earthen powder that has binding properties. , and the animal is characterized in that raw bones are boiled at a high temperature, then fired at a high temperature and then pulverized, the bone powder and earthen powder having binding properties are blended and kneaded with water, and this is granulated and then fired. The gist is a method for producing a bone-based active material.

(Function) The above-mentioned animal bone-based active material ionizes alkali and alkalinizes the atmosphere with animal bone components such as calcium, and has a freshness preserving effect by preventing oxidation.
The presence of countless pores formed in the bone itself provides a filtration effect, and both functions serve to aggregate organic matter.

(Example) The animal bones that are the raw materials for the animal bone-based active material of the present invention are bones that were conventionally almost discarded at livestock farms, especially bones of animals such as cows, horses, and sheep, which are mainly composed of hard bones. Ru. The bones of pigs, pigs, etc. have a lot of cartilage, and most of them melt during the boiling process during production, so they are not suitable for use as raw materials.

The above-mentioned raw bones are cut into appropriate sizes and into sizes that are easy to burn, and then put into a pressure cooker (compression cooker) and boiled at about 200 to 400°C for about 90 minutes. Next, this bone is placed in a kiln and heated to 900-1100℃.
After baking, it is fired for about 60 to 180 minutes, and then allowed to cool naturally in the furnace for about 60 minutes to return to room temperature or a state close to this temperature.

If organic substances other than bone components such as seratin, fat, white matter, and glue remain in the bones, they will cause oxidative decay, so it is important to ensure that they are removed. By the above boiling process, organic matter adhering not only to the outside but also inside the pores can be separated and removed from the bone. At this time, if the boiling is done at a lower temperature or for a shorter time than the above, the organic matter cannot be removed sufficiently, causing problems in the subsequent firing process. There is no advantage to using boiling conditions at a higher temperature or for a longer time than the above.

In this way, by removing the organic matter from the long sword in the boiling process and then passing it through the firing process, it is possible to completely remove the remaining organic matter, and at the same time reduce the humidity (moisture) in the bone.
can be reduced to several percent or less, preferably to almost 0%. Firing without a boiling step is not preferable because it causes significant combustion of organic matter and smoke generation, resulting in environmental pollution, discomfort during work, and damage to equipment.

If the firing conditions are clearly lower than the above, the bones will become carbonized, and if the firing conditions are too high, the bones will turn to ash.
In either case, the product will not function as intended by the present invention. According to the above conditions, the bone becomes white and maintains its original state with numerous pores.

After the above-mentioned firing and cooling, the bones are crushed and put in a powder machine to produce approximately 20 to 200 meshes, particularly preferably 50 to 10 meshes.
0 mesh powdered bone meal.

In order to form the active material of the present invention, it is preferable to use the powder form.

In the case of bovine bones, the above-mentioned bone powder yield was 40% by weight compared to raw raw bones. The particles contain calcium (approximately 33
The main components are phosphorus (approx. 16.7%), barium (approx. 1.03%), sodium (approx. 0.76%), sulfur (approx. 0.64%), and magnesium, potassium,
It is composed of chlorine, amine, iron, etc., and has countless microscopic pores that communicate with each other both inside and outside the particle. Ionization is alkaline due to calcium etc.

An animal bone-based active material is produced by kneading the bone powder and binder soil. The binding soil is made of zeolite powder of about 200 to 500 mesh, which is made by baking inorganic clay at around 600℃ for about 3 hours, and other soil powders with binding properties (
clay powder) is used. Kaolin etc. may also be used.

A mixture of around 60 to 90% bone powder (same weight percentage below) and around 10 to 40% of the above binder soil powder is mixed with around 20 to 30% water and kneaded until the whole becomes uniform. Spherical shape with a diameter of 1 to 20 mm or a thickness of 5 mm depending on the
A plate-shaped or rod-shaped animal bone-based activated material with a diameter of ~10 mm and a square size of around 50 mm is produced.

The above size is easy to handle for practical purposes, but
It is not limited to the above range.

The above animal bone-based active material is dried in the shade for about 2 to 8 days (shorter in the summer, longer in the winter) or dried with far infrared rays for an appropriate period of time to prevent cracking, and then dried at around 800 to 1100℃. Baked for about 1 to 2 hours to reduce the moisture content to a few percent or less, preferably about 0%, left as is, and taken out after 2 to 6 hours depending on the baking temperature and size, preferably in non-breathable packaging. Store it in a sealed container or freeze it, and take it out and use it as needed.

In the above, rapid cooling after firing is not preferable because it causes moisture to be adsorbed to the dried bones and causes the pH value of the bones to become lower (acidification). Also,
It is also unfavorable in terms of preventing cracks.

The above animal bone-based active material is mixed with a relatively large amount of binder soil powder when strong binding properties are required, and a large amount of bone powder is mixed with the animal bone-based active material for applications that require stronger adsorption and alkalization. It is preferable to change the mixing ratio depending on the purpose, such as, and the size can be set appropriately depending on the purpose.

For example, a small size of around 1 to 5 seconds is used for filter media, and a relatively large size of about 5 or more reports mixed with 60 to 90% bone meal is used to maintain freshness by preventing food oxidation to prevent oil deterioration. It is better to do so.

When the active material according to the present invention is immersed in cold water (ordinary tap water), bubbles are generated and the pH value of the water is 7.5 to 1.
It became 0. This range depends on the mixing ratio of bone powder, the size of the active material, etc.

According to the above active material, the atmosphere of liquid or air can be changed from an acidic side to a neutral or alkaline side through ion exchange. At the same time, it is possible to prevent organic matter from rotting, or to adsorb or aggregate organic matter to prevent acidification of liquid or air due to this, and to maintain its freshness. The above effects are theoretically permanent as long as bone quality exists.

Further, when a liquid or air is passed through the active material layer, filtration and purification effects are performed by the adsorption action of the active material.

The materials that make up bones are generally harmless to the human body.

Examples of uses of the present invention are as follows.

If the powder according to the present invention is attached to or contained in a filter material such as urethane foam, it can be used to alkalize liquids and gases with carunium ions or to neutralize acidic conditions, and at the same time, to purify them with sterilizing action. If the pieces of the present invention are used as a filter material, it is possible to make tap water weakly alkaline (ionized), which is favorable for the human body, and by circulating indoor air, it can be purified with weak alkalization and sterilization. It is effective for the human body, and by passing organic wastewater through this filter material, it can be purified by alkalizing or neutralizing it, and it can also be used in cooling towers, solar water heaters, etc. By disposing the active material of the present invention in the water, it is possible to prevent the growth of green algae and at the same time, to prevent water from rotting. Since the active material of the present invention used in these materials is a fired hard aggregate with micropores, adhering impurities are liberated by washing, and permanent use is possible.

Furthermore, since the active material of the present invention is originally animal bone, it provides nutrients such as carunium, and can be added to foods as an additive, and also functions as a preservative and antioxidant. It does not pose any toxicity risks like traditional synthetic preservatives and synthetic antioxidants.

Moreover, the active material of the present invention contains potassium and phosphorus, and for example, deodorized and dried sludge discharged from livestock farms contains nitrogen, ammonium sulfate, ammonia, etc. as organic substances. The active material of the present invention can be mixed with these materials to form an organic fertilizer, and since the active material of the present invention has countless micropores and is dried, it absorbs oxygen in the soil while keeping the soil soft. It also creates an alkalizing atmosphere around it, and fulfills this function while the aggregate remains, so unlike conventional lime, which aggregates with moisture and hardens the soil, it also acts as a soil improvement agent. Become.

In addition, if the active material of the present invention is mixed in water, fish, etc. (tuna in the experiment) is immersed in this liquid, taken out, wrapped in a regular film, and stored in a household refrigerator, 2
Even after a week had passed, there was no discoloration and no odor of putrefaction, and a slight odor of putrefaction began to appear after nearly 20 days. When plants are soaked in water containing the active phase mixture of the present invention,
Plants tend to grow in small increments, similar to those with roots, and edges and vitality are increased, and is particularly effective on fibrous plants such as chives and green onions.

Experimental example Tempura oil used by a bento manufacturer was used for 22 days, and regular oil A and the same tempura oil were used.
101111I11 diameter, 6g of the active material of the present invention, consisting of 80% by weight of beef bone powder and 20% by weight of zeolite powder, was added in advance to oil 21 at a ratio of 4 pieces, and the activated material was used commercially for 22 days as it was. The results of testing the state of deterioration with lumber-containing oil B, and the results of a Table 1 shows the results of testing the deterioration state of the filtered oil C in which the oil B was passed through the layer. The test was conducted by the Japan Food Hygiene Association.

Incidentally, the above-mentioned activation injection into the oil was carried out in a can having a large number of holes on the circumferential side.

Table 1 The above acid values were determined by the standard oil and fat analysis test method, and the carunium values were determined by atomic absorption spectrophotometry. For reference, the acid value of new oil is 0. 1~0. It is 2.

Also, according to the taste test of tempura using each of the above oils, the fried tempura was better when fried using oil B and C compared to oil A.
It was very light, light, and good, and the difference was remarkable.

In addition, the oil temperature is preferably around 50 to 100° C. when the aggregate has good reactivity and flowability and the filtration action is more efficient.

As is clear from the above, when the active material of the present invention is added to oil, it adsorbs and aggregates organic substances such as meat juice, sugar, and fat contained in the oil, thereby preventing acidification of the oil. Not only that, but it also alkalises the oil and prevents it from deteriorating. Also,
By passing oil through the filtration layer, impurities and aggregated organic matter were filtered out, the quality was restored to a state close to new, and the freshness was maintained. At the same time, it also has the effect of adding some bone material, such as carunium, to oil and fried foods.

(Effects of the Invention) As described above, the present invention mixes and fires the calcined bone powder and clay material to form an active material, and at the same time, maintains freshness by preventing oxidation through the action of numerous pores. It restores freshness, has a filtration and flocculation effect, and can also add bone-constituting materials such as calcium, and can be used for a variety of purposes, but it is especially useful for preserving the freshness of foods and food processing materials by preventing oxidation, and for storing waste liquids or used materials. It has remarkable effects by filtering tempura oil and coagulating organic matter. It also has a remarkable effect on preventing pollution caused by domestic wastewater caused by waste oil and organic matter.
