[0002]

2. Description of the Related Art Conventionally, so-called baked bone meal prepared by treating animal bone at high temperature and pulverizing it is used as a valuable animal calcium source in the fields of food additives, nutritional calcium preparations, health foods, etc. It has been widely used. Bone of animal, such as cow, pig, fish, etc., is burned at high temperature and crushed, and the mixture is prepared by adding excipients, binders, flavors, etc. to burned bone powder and granulating the mixture. The production of granule-shaped products by drying has been carried out so far, and is widely used, for example, by blending it into various foods and drinks as a calcium enhancer and the like.

As dietary changes require efficient supplementation of nutrients and the importance of nutritional balance is highlighted with the development of health science, nutrition of various health foods, vitamins, minerals, etc. Replenishers, food additives, etc. are frequently used, and the source of raw materials covers a wide range from natural animal and plant materials to inorganic materials. It is important for these raw material sources that, when administered or ingested into the body, each component is effectively and reliably absorbed, taken up by the metabolic system, and its physiological activity is effectively utilized. From the point of view, the search and research and development of high quality raw material sources are being conducted.

As described above, the importance of the source of raw materials for various nutrients has been recognized, and in fact, various new products such as health foods and nutritional supplements have been developed. Above all, the intake of calcium tends to decrease due to an increase in the intake of secondary processed foods, etc., and it has been pointed out that problems such as osteoporosis have been pointed out in the aging society, and as a nutrient The importance of calcium is increasing.

Under such circumstances, various kinds of calcium sources have been searched for and researched and developed. For example, milk-derived calcium, calcium carbonate, calcium lactate, crustacean-derived calcium, small fish and shellfish. Various raw materials such as derived calcium are used, and products obtained by processing the product form into granules, tablets, powders and the like are commercialized. The main discussion so far on such calcium preparations has been more about the qualitative problems as a calcium source such as the absorbability and availability of calcium in vivo, rather than the production of calcium preparations. With regard to the process, it was considered that ordinary formulation technology was used as it was, and that there were no problems with the application of existing technology.

[0006] As described above, it is no exaggeration to say that the point of research and development of new calcium preparations was to find a useful calcium source, and starch, lactose, and crystalline cellulose were used as the calcium source as the main raw material. It was general to formulate excipients such as by mixing them, mixing them, granulating and drying, and formulating them by using a usual manufacturing technique.

[0007] The ordinary calcium preparation thus produced is shipped after production, and is used for distribution, but it usually takes several months before it is actually used. Regarding quality maintenance during that time, a special quality control system such as storage under constant temperature conditions is rarely used. However, in the case of products that use calcined bone meal prepared by crushing animal bones at high temperature and crushing it as a calcium source, sometimes there is a problem of quality deterioration over time depending on storage management conditions. Therefore, in order to prevent it, it was forced to adopt a high level quality control system for quality maintenance.

Even under normal use conditions, it is difficult to completely prevent quality deterioration of calcium preparations containing calcined bone powder as a source, especially quality deterioration due to discoloration. For example, calcined bone powder was used. In many cases, products such as sprinkles and calcium fortifiers turned brown in a relatively short time and their commercial value was impaired.

[0009]

Therefore, the inventors of the present invention, while aiming to solve the drawbacks of the conventional products, are searching for the cause of the occurrence of the quality deterioration phenomenon.
Animal bones such as beef bones, pork bones, fish bones, etc.
When baked at a degree, the pH will be around 10-11,
Calcium unfired bone meal calcium phosphate _{type, CaO 3 (PO 4) 2} · nH 2 O · 4CaO · at the firing bone powder
It was found that the calcium component of the phosphoric acid / calcium oxide type changed to P ₂ O ₅ type and exhibited strong alkalinity.

Further, in the case where a granulated product is produced by further adding excipients such as starch, lactose, sugar, glucose, fructose, and various sugars generally used in food granules to the above-mentioned baked bone meal, the above-mentioned We found that the alkaline calcium component is the main cause of the quality deterioration of calcium preparations, such as discoloring these sugars to brown and impairing the taste required for the product, and found an effective method to improve this. We started the research to develop it.

As a result, the inventors of the present invention, when producing animal food granules using 3 to 60% of the baked bone powder prepared by treating animal bone at high temperature and crushing it, use the burned bone powder raw material such as citric acid. It was found that the above problems can be solved by mixing in the presence of the above organic acid, adjusting the pH to pH 8.0 or less, granulating, and further drying, and completed the present invention.

[0012] That is, the present invention provides a food-grade granule containing calcined bone meal as a main raw material, the quality of which does not change with time and the quality of which is stable, and a calcium-fortified food comprising the food granule. It is intended.

Further, the present invention is mainly based on baked bone meal,
Excipients such as saccharides, a manufacturing method of the food granules that can effectively prevent the time-dependent quality deterioration phenomenon observed during the production of the food granules produced by mixing the binder and the binder. It is intended to provide.

Furthermore, the present invention can completely prevent quality deterioration due to discoloration that occurs in the manufacturing process and storage process of food granules containing baked bone powder as a main raw material, and can avoid the above-mentioned taste problems. It is an object of the present invention to provide a method for producing the food granules.

[0015]

The constitution of the present invention for achieving such an object comprises the following (1) and (2). (1) When producing animal food granules prepared by treating animal bones at a high temperature and crushing and preparing burned bone meal in an amount of 3 to 60%, a pH of 8 is obtained by mixing an organic acid such as citric acid. A method for producing granules for food, which is characterized by adjusting to 0.0 or less. (2) Food-grade granules produced by the production method described in (1) above, in which 3 to 60% of raw material is mixed with baked bone powder prepared by treating animal bones at high temperature and pulverizing. (3) Produced by treating animal bones at a high temperature and crushing and preparing calcined bone powder, which is mixed in an amount of 3 to 60%, and mixed with an organic acid such as citric acid to adjust the pH to 8.0 or less. The calcium-fortified food obtained by blending the food granules according to (2) above in a food material.

Next, the structure of the present invention will be described in detail.
The baked bone powder used in the present invention is a high-temperature treatment of animal bones.
For example, it is a calcined bone meal prepared by pulverizing calcined material at about 400 to 1000 ° C., and appropriate animal bone such as beef bone, pork bone, and fish bone can be used. When the bones of these animals are fired at about 400 to 1000 ° C, the pH is 1
A strong alkali of 0 to 11 is exhibited.

The baked bone powder is used as a main raw material, and an excipient for producing food granules, a binder, and if necessary a flavoring agent are added to the raw material, and the whole is thoroughly mixed and granulated. The burned bone powder is preferably blended in the raw material in an amount of 3 to 60% in view of the blending efficiency of the active ingredient. Excipients include starch, lactose, crystalline cellulose, sucrose, glucose, mannitol, gum arabic, sodium alginate, hydroxypropyl starch (HPS), calcium sulfate, calcium hydrogen phosphate,
Conventional materials such as calcium carbonate, sodium hydrogen carbonate, talc, light anhydrous silicic acid, methyl cellulose, carboxymethyl cellulose, sodium alginate, PVP, etc. are used.

These excipients are used in the form of fine powders,
It may be mixed well with the above-mentioned baked bone powder as a main raw material and granulated into a granule form. However, these excipients themselves are manufactured in the form of fine granules, and the above-mentioned baked granules are granulated by the same method. It is also possible to mix bone meal into a product. For example,
Taking lactose as an example, in addition to conventional powdered lactose, crystalline lactose having 60 to 100 mesh, 80 to 150 mesh, spherical particles such as spray-dried lactose, and direct shaping Not only mere crystals but also granulated forms can be used including those made as agents.

Excipients are required to be uniformly and well mixed, and it is well known that starch and the like have different properties depending on the water content of the same substance, and hardly adsorbs water like calcium hydrogen phosphate. There are three types, such as starch, which adsorbs a certain amount of water such as starch, and lactose, which dissolves at a constant humidity. Any of these can be used by pretreatment such as crushing.

The granulated preparation requires a binder, a disintegrating agent, a coating agent, a lubricant and the like, and these additives can be appropriately blended as needed.

In the present invention, in addition to these excipients, an organic acid is further mixed as an essential component to adjust the pH to 8.0 or less. As the organic acid used in the present invention, for example, citric acid, tartaric acid, lactic acid, acetic acid, malic acid and the like can be preferably mentioned, but any organic acid can be used and is not limited to these. It is not something that will be done. The amount of the organic acid mixed varies depending on the type of the organic acid, but the amount used is not limited as long as it can be adjusted to pH 8.0 or less. Also, the pH
If it is more alkaline than 8.0, the desired effect cannot be obtained.

These organic acids are mixed into the main raw material in the pretreatment step of the raw material for the baked bone powder, but it is also possible to mix them by means such as spray in the subsequent kneading and granulation steps. is there. In any case, it is important to formulate in a granular form in the presence of an organic acid over the whole process of granulating the baked bone powder, and the mixing method, etc., may be an ordinary method as appropriate. You can use it.

The granules can be roughly classified into a wet method and a dry method. The food granules of the present invention can be manufactured by any method. Among them, the wet method comprises steps of humidity control, pulverization, addition of liquid, mixing, granulation, drying and sizing. First, humidity control and pulverization are performed as pretreatments.
The moisture content of the raw material is adjusted to a predetermined value by the humidity control step. Next, in order to make the crystal grain size of the raw material uniform, the grain size is pulverized to, for example, 200 mesh or less, preferably 100 to 200 mesh grain size. The pretreated raw materials are mixed, a solution of the binder is added thereto, and the mixture is added and mixed, and the mixture is supplied to a granulator and granulated into a granule form.

In the dry method, the raw material powder is strongly pressed without using a solvent to prepare a large tablet-like or plate-like solid matter,
This is a method of roughly crushing this into granule sizes, and the edible granules of the present invention can also be produced by such a method.

In the case of granulating by the above-mentioned wet method to produce granules, various granulating methods can be used.
Appropriate granulation methods such as crushing granulation, extrusion granulation, mixed granulation, tumbling granulation, fluidized bed granulation, spray granulation and injection granulation are used, but especially fluidized bed granulation and extrusion granulation. Grains are preferable.
In the case of extrusion granulation, kneading is required as a pre-step of granulation. Kneading machines include a crusher, various kneaders, and pony mixers, but the type of binder, the amount and model of addition,
The kneading time affects the consistency of the kneaded product, and it is necessary to properly set the above conditions in relation to the granulation model.

In fluidized bed granulation, a device for spraying a binder is attached to a fluidized bed dryer, and granulation and drying can be performed by the same machine. It can also be used for coating, and can be either a badge type or a continuous type. The fluidized bed granulation has a uniform temperature distribution, can be rapidly dried even at a low temperature, and can obtain a product having a uniform particle size. Therefore, the fluidized bed granulation is particularly preferably used in the present invention.

Extrusion granulation is a method in which a kneaded product is extruded from a wire mesh or punching metal for granulation, and is generally widely used for wet granulation of foods, pharmaceuticals, etc.
It is also preferably used in the present invention. There are two types of mesh-type granulators, a single type in which one rotor reciprocates on a wire mesh and a double type in which two rotors continuously rotate inward, and the mesh size is at least about 30 mesh. A product with a slightly uneven grain and low density can be obtained. A communicator such as a tornado mill is also suitably used for wet extrusion granulation. One tornado mill for granulating wet mass, the other one
A continuous drying system in which a table is used for sizing and a conveyor and a dryer are arranged between them is also available.

[0028] A cylindrical granulator presses a kneaded product when a blade inscribed in a cylindrical screen rotates, and a screw granulator such as an Eck-pelletter presses a kneaded product compressed by a screw. A cylindrical punching metal is extruded, which is preferable because a dense granular material can be obtained. Screen eyes have a minimum of 0.5 m
Those up to about m (about 30 mesh) can be used. In addition, an Alexander machine composed of three perforated cylinders, a foot machine that is compressed by a gear-type roller, and is pushed out through a hole communicating from the root of the tooth to the outside can also be used.

In extrusion granulation, it is necessary to dry after granulation. As the method, a box type, a ventilation type, a vacuum type, a fluidized bed type, an infrared type, a high frequency type and the like can be used. Among them, the fluidized bed drying is preferably used because the temperature distribution is uniform, the drying time is very short, and the particles are not powdered. If necessary, the dried granules are subjected to a sizing machine for the purpose of loosening the agglomerates before sizing. A Fitzmill or a net-type rectifier is used for this. Next, the sized granules are sized by a sifter such as a gyro shifter or a vibration sieve into three types of granules having a predetermined particle size width, coarse particles and fine powder. The coarse particles are crushed and further divided into a product and fine powder, and the fine powder is returned to the granulation step and the above-mentioned operation is repeated to produce the food granule of the present invention.

The thus-prepared food-grade granules can be sprinkled with, for example, other compounding raw materials, and can also be used as it is for liquid foods such as calcium enhancers for rice cooking, beverages, soups, etc. It is preferably used as a calcium supplement, health food, or raw material granules of various foods such as biscuits, cookies, bakery products, and rice cracker products. The blending ratio of the food granules when used as the raw material granules is not particularly limited, and is appropriately determined according to the type of the target food and the like.

By the way, as described above,
When baked at about 400 to 1000 ° C, the pH is 1
It has a strong alkalinity of about 0 to 11, which means that the calcium component of the calcium phosphate type unbaked bone powder is CaO ₃ (PO ₄ ) ₂ · nH ₂ O · 4CaO · P ₂
It is presumed that this is due to the change of the phosphate component of O _{5 into} a calcium oxide type calcium component. Therefore, if the obtained baked bone powder is used as it is, it is affected by the calcium composition, lacks stability over time in the manufacturing process and storage process of the granule preparation, and becomes a factor that deteriorates product quality, especially discolors the product. In addition, when a granular product is added to a food for strengthening, problems such as significantly impairing the taste required for the food occur, but by adding the organic acid and adjusting the pH to a specific range, Can completely avoid such problems. It should be noted that, even when the food grade granules of the present invention are added to other foods, it is confirmed by a taste test by a panelist that no problems such as significantly impairing the taste of foods as found in conventional products occur. ..

As described above, conventionally, various excipients have been blended with the baked bone powder and a granule preparation has been prepared by a conventional method, or, in general, various pharmaceutical ingredients have been used. Although there are examples of using an organic acid as a mere sour component when manufacturing a tablet-shaped product, an organic acid was used to improve the temporal stability of the quality of granule products made mainly from baked bone powder. No examples have been given so far, and the present invention is the first.

The organic acid used in the present invention is used in order to effectively prevent the quality change of the granular product due to the calcium composition of the baked bone powder when the baked bone powder is used as the main material. Such an effect is specific to the combination of baked bone powder and organic acid, and is related to the use of conventional organic acids used in unspecified large numbers of foods, such as organic acids as mere acidulants. It is completely unexpected from the known facts.

Next, the results of a storage test conducted to verify the stability of the quality of the food granules of the present invention over time will be shown.

Test Example Calf bone was calcined at 1000 ° C., crushed and pulverized to obtain 40 parts of calcined bone powder, 40 parts of lactose, 8 parts of corn starch, 4.2 parts of dextrin, and 1.8 parts of citric acid. Each,
Put in a fluidized bed tank of a granulator, mix, and spray a mixture of 100 parts of purified water and 5 parts of gum arabic, granulate at a product temperature of 40 ° C., and dry to obtain a particle size of 10 to 10.
0 mesh, pH 7.2 food grade granules were obtained.

As a comparative control example, except for citric acid in the raw material components, granules prepared in the same manner in the absence of citric acid were used. Each sample was housed in a closed container and left at 25 ° C. or 30 ° C. in a bright place for a storage test. The quality was evaluated visually by using the degree of change in color tone as a standard. The results are shown in Table 1. In Table 1, the products A and C were stored at 25 ° C., and the products B and D were stored at 30 ° C., respectively.

[0037]

[Table 1]

As is clear from Table 1, the comparative control examples are:
Both Product C and Product D discolored and turned brown after storage for 30 days, but the food granule product of the present invention showed no change in color tone even after 120 days, and the quality stability over time was high. there were.

[0039]
