2. Description of the Related Art A conventional granular composition containing fats and oils is
A powdered oil and fat obtained by spray-drying an emulsion consisting of water, oil and fat, an emulsifier, starch and the like under a high temperature atmosphere into granules was the mainstream. Further, also in the granulation method, a method in which an aqueous solution of a polysaccharide or the like is used as a binder to granulate and dry in a high temperature atmosphere has been the mainstream. However, in these powdery fats and oils production methods and granulation methods, a drying step under high temperature is essential, and therefore not only the deterioration of fats and oils is severe, but also when flavored oils and fats are used. Had a problem that the flavor was deteriorated and the flavor component was volatilized to weaken the flavor. Furthermore, since it is a powder / granular oil / fat obtained by spray-drying an emulsion, there is a problem that the oil / fat is emulsified with the hot water when dissolved in hot water, and the rich taste of the oil / fat is hardly felt when eating or drinking.

In order to solve the above problems, Japanese Patent Laid-Open No. 64-64-
In Japanese Patent No. 27430, there is proposed a method for producing a granular oil or fat by mixing and stirring oil and fat, a base material for inclusion of oil and fat, and a polyol. Japanese Unexamined Patent Publication No. 10-095992 proposes a method in which a starch hydrolyzate is granulated and then oil is absorbed in a temperature range above the melting point of fats and oils to produce powdered fats and oils. Further, in Japanese Patent Application Laid-Open No. 7-284380, as a method for producing a granular oil-containing food, solid fat and food materials other than fat and oil and a decomposed product of starch are heated and mixed in a temperature range above the melting point of solid fat, and then solid fat is added. A method for producing a granular oil-containing food product by cooling to a temperature below the melting point has been proposed. However, these methods could not sufficiently increase the fat and oil content. Therefore, in order to impart the richness and flavor of oils and fats to granular / powdered instant soup, it is necessary to add a large amount of the above-mentioned granular oils and fats, which leads to an increase in cost and there is a problem in versatility.

On the other hand, as a method for producing an oil-containing granular composition having a high oil and fat content, a method of impregnating dietary fiber with oil and fat has been disclosed. (JP-B-41-7422, JP-A-61)
No. 15648, Japanese Patent Laid-Open No. 7-278586,
JP-A-8-134493). However, there is no mention in the disclosed patent specifications of the physical properties of the resulting granular composition. When the oil-containing granular composition is industrially used for food, it is required to have physical properties such as high density, less crushing and high fluidity. It is mechanized in the food industry today, and it is necessary to prevent various problems such as clogging of the machine when adding the granular composition to food or when filling the container with the granular composition. Because there is. In the past, there is no technique for obtaining an oil-containing granular composition having a sufficiently high fat content and high density and high fluidity.

[0005]

An object of the present invention is to provide an oil-containing granular composition having a physical property of having a small angle of repose and a method for producing the same.

It is a method for producing the oil-containing granular composition according to the seventh aspect.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, dietary fibers are fibrous, and the average fiber length of each fiber must be 100 μm or more, and more preferably 150 μm or more.
Further, dietary fiber having an average fiber length of 100 μm or more and an oil absorption capacity of 5 times or more of its own weight is more preferable. Average fiber length is 1
If it is less than 00 μm, the oil or fat is significantly exuded during granulation and cannot be used. Examples of the origin of dietary fiber include wheat, soybean, corn, pulp and the like, and wheat is preferable. As a commercially available dietary fiber that meets the above conditions, "Vitacell WF200" by Rettenmeier
(From wheat) can be exemplified. The average fiber length refers to the average value of the lengths of fibers existing in the oil-absorbing material containing dietary fiber. Dimensions of the smallest unit that constitutes each oil-absorbent material (If the configuration unit is vertically long, such as linear fiber material or rod-shaped porous material, the length and thickness When the shape of the structural unit is close to a square, the average value of the length of one side is defined as follows. Each oil-absorbent material is enlarged with a microscope until the smallest unit (particle or fiber) that constitutes it can be discriminated, and 10 representative ones are selected from among the observed smallest constituent units.
If the shape is vertically long, measure the length and thickness, and if the shape is close to a square, measure the length of one side, calculate the average value of 10 points, and then calculate the numerical value as the average value of thickness and length. Is defined as the average value of, and the average value of the length of one side.

In the production method of the present invention, dietary fiber can be easily granulated by dry stirring granulation in the presence of oil and fat, which does not require addition of water. The dry stirring granulation of the present invention is preferably performed by a stirring granulator equipped with a crushing blade in addition to the stirring blade. The stirring blade is also called a main shaft. The crushing blade is also called a granulation axis or a secondary axis. In a stirring granulator equipped with a stirring blade and a crushing blade, the rolling compaction action by the stirring blade and the crushing and sizing action by the crushing blade act simultaneously, so that each particle has a high density due to the rolling compaction action. And granulation by crushing and sieving are repeated to obtain granules with a uniform particle size and high specific gravity (Granulation Handbook, edited by Japan Powder Industrial Technology Association, published by Ohmsha, p379-389). .
Further, since it is strongly affected by rolling compaction, the surface of the granules becomes smooth and the fluidity becomes high. Here, the “high density and high fluidity” state of the granular composition can be specifically expressed by the following index. That is, a granular composition having a high bulk specific gravity, a low degree of compression and a small angle of repose is a “high density and high fluidity” granular composition. Desirable physical properties are a bulk specific gravity of 0.40 g / ml or more, a compression degree of 22% or less, and an angle of repose of 49 degrees or less.

In the broad sense, agitation granulators include those with only agitation blades such as planetary type universal agitation mixers (Granulation Handbook, edited by Japan Powder Industry Technology Association, published by Ohmsha, p379-). 389). However, in such a simple mixer, since there is no crushing blade, crushing of coarse particles does not occur, so the rolling compaction action does not act repeatedly on each particle. Therefore, it is difficult to obtain an oil-containing granular composition having a high density and high fluidity, which is the object of the present invention. As a stirring granulator equipped with a stirring blade and a crushing blade, Nara Machinery Co., Ltd. "Heavy duty type granulator" and "Pharma type granulator", Paulek Co., Ltd. "Vertical Granulator", Examples include "New Gra Machine" manufactured by Seishin Enterprise Co., Ltd., "High Speed Mixer" manufactured by Fukae Kogyo Co., Ltd., "Gral" manufactured by Fuji Paudal Co., Ltd., and the like. When a stirring granulator equipped with a stirring blade and a crushing blade is used, stronger energy is given to the granulated material, as compared with the case where a stirring machine having only a stirring blade is used. Therefore, dietary fiber that meets the above-mentioned conditions is essential. Further, according to the dry stirring granulation of the present invention, granulation can be completed in a relatively short time, and a step of drying water is not necessary. Therefore, in the case of producing a granular composition containing a scented oil or fat, there is an advantage that scent loss can be minimized. In dry stirring granulation, it is preferable to maintain the temperature during stirring and mixing at a temperature at which fats and oils do not crystallize during granulation.

In the present invention, the weight of fats and oils with respect to dietary fiber 1 which is fibrous and has an average fiber length of 100 μm or more is preferably in the range of 1.5 to 12.
The range of 5 to 6 is more preferable, and the range of 1.5 to 3.0 is preferable.
It is more preferable that the range is When the weight of fats and oils relative to dietary fiber 1 is less than 1.5, the densification of the oil-containing granular composition does not proceed due to the presence of a large amount of dietary fibers in the fats and oils, and the specific gravity is low and the fluidity is poor. It becomes a granular composition. When the weight of fats and oils with respect to dietary fiber 1 is more than 12, it cannot withstand strong stirring during granulation and becomes a paste during granulation, which makes granulation difficult.

In the present invention, the oil and fat content of the oil-containing granular composition is 30 to 75% by weight, preferably 40 to 75% by weight,
More preferably, it is 50 to 70% by weight. When it is less than 30% by weight, the composition is a granular composition having less fat and oil flavor and richness. If it exceeds 75% by weight,
Blocking resistance is poor and blocking occurs during distribution and storage.

The oil / fat used in the present invention has a melting point of 5 or less.
Oils and fats of 5 ° C or lower are preferable, 20 to 55 ° C is more preferable, and 30 to 55 ° C is most preferable. Melting point of oil is 20 ℃
When lower oils and fats are used, the obtained oil-containing granular composition has a low degree of compression when stored in an atmosphere at 20 ° C. or higher. That is, when a load is applied, it easily collapses. When fats and oils having a temperature higher than 55 ° C. are used, crystallization after dissolution is fast and crystallization easily occurs in the mouth, making it difficult to eat and drink. The fats and oils used in the present invention are not limited as long as they are animal and vegetable fats and oils that can be used in foods, and examples thereof include palm oil, palm kernel oil, coconut oil, sunflower oil, soybean oil, rapeseed oil, corn oil, sesame oil, and peanut. Oils and fats using one or more kinds of oil, cacao butter, monkey butter, shea butter, lard, beef tallow, fish oil, etc., and processed fats and oils obtained by fractionating, curing, transesterifying, etc., and these Mention may be made of combined fats and oils. In addition, the oil and fat may contain an oil-soluble component that can be used in foods. To give examples of oil-soluble components,
Mention may be made of oil-soluble flavors, emulsifiers, etc., and mixtures of these with fats and oils.

The fats and oils used in the oil-containing granular composition of the present invention can be flavored, and as a flavoring method, milk fat, lard, beef tallow, fish oil, sesame oil, perilla oil, peanut oil, coconut oil and the like can be used. Oils and fats having a unique flavor, or may be flavored by appropriately blending oil-soluble flavors, oils and fats used in the present invention to further enhance the flavor and rice bran, milk powder, green onions, solid flavor substances such as sesame After heating and mixing, the flavor oil and fat from which insoluble matter is removed may be used. Furthermore, edible powdery or granular animal and plant extracts, fragrances, amino acids,
You may mix | blend the seasoning with which nucleic acid, inosine acid, organic acid, etc. were mix | blended before or after granulation.

In the present invention, for the purpose of further improving the bulk specific gravity and fluidity of the oil-containing granular composition, an oil-absorbing material having an oil absorption capacity of 0.5 times or more of its own weight after granulation is used as the oil-containing granular composition 1
It is also possible to mix 0.5 parts by weight or less with respect to parts by weight and perform stirring granulation again. However, if the amount exceeds 0.5 part by weight, not only the oil and fat content of the granular composition decreases but also the time required for production increases and the productivity decreases. The reason why the bulk specific gravity and fluidity of the oil-containing granular composition are improved by the above operation is considered as follows. That is, it is considered that since the oil-absorbing material added after granulation covers the surface of the granules, fluffing of dietary fiber is suppressed and the surface of the granules becomes smooth, so that the bulk specific gravity increases and the fluidity increases.

The above oil-absorbing material is not particularly limited as long as it can be used in foods. Examples include starch such as dietary fiber, potato, tapioca, corn, wheat, and rice, processed starch such as pregelatinized starch, modified starch such as octenyl succinate, phosphorylation, and hydrolysates thereof. . Further, the oil-absorbing material used has an oil-absorbing ability of 0.5 times or more, preferably 1 time or more, more preferably 2 times or more of its own weight. Oil absorption capacity is 0.5 of its own weight
When the amount is less than twice, the effect of improving the heat resistance of the oil-containing granular composition decreases, and blocking easily occurs. As marketed products of oil-absorbing material, "Vitacel WF200", "Vitacell WF600", "Vitacell WF6" manufactured by Rettenmeyer
00/30 "," Oil Q No.5 "manufactured by Nichidake Chemical Co., Ltd.
0 "and" Oil QS "," Pine Flow "manufactured by Matsutani Chemical Co., Ltd., and the like.

The stirring speed at the time of stirring and granulating the oil-containing granular composition of the present invention varies depending on the model and scale, and the particle size of the oil-containing granular composition is appropriately adjusted according to the purpose for which it is used. Products that have been classified as necessary are made into products. For example, when used in granular instant soup,
The average particle diameter is preferably 0.1 to 3 mm.

Select 10 representative points from among the smallest constitutional units observed in the image, and for each of them, if the shape of the smallest constitutional unit is vertical, such as linear fiber material or rod-shaped porous material, Regarding the thickness, when the shape of the minimum constitutional unit was close to a square like a plate-shaped porous material, the length of one side was measured, and the average value of 10 points was calculated. In this way, the average value of the thickness and the average value of the length, or the average value of the length of one side of the minimum unit constituting each oil-absorbing material was obtained.

[0019]

[Table 1] As a result of microscopic observation, the mechanism of oil absorption was estimated as follows. "Vitacel WF200" and "Vitacell WF600"
Is an aggregate of cellulose fibers or hemicellulose fibers, and oil is retained in a network structure formed between the fibers.
Oil QS, Selfur, and Avicel all consist of particles having porosity, and oil is retained in the fine pores of each particle.

Example 1 34 parts of Vitacell WF200 as dietary fiber were put in a high-speed stirring granulator "Heavy Duty Type NMG-10L" manufactured by Nara Machinery Co., Ltd., 45 parts of lard flavored with soy sauce and palm. These oils and fats which were mixed with 18 parts of hardened oil and melted at 50 ° C were added, and the stirring blade rotation speed was 150 rp.
m After stirring for 7 minutes at a rotation speed of 3000 rpm of a crushing blade, 3 parts of Oil QS (manufactured by Nitto Kagaku Co., Ltd.) was added, and the mixture was further stirred at the same rotation speed for 2 minutes. After stirring, the granules passing through the 8-mesh sieve were collected to obtain an oil-containing granular composition. In the obtained oil-containing granular composition, the melting point of fats and oils after preparation is 43
C., the weight ratio of fats and oils to dietary fiber was 1.9, and the content of fats and oils in the entire composition was 63% by weight. The obtained oil-containing granular composition had a good result in the crystallization test and a good result in the blocking test. The ratio (yield) of the granules discharged from the machine that could pass through the 8 mesh sieve was 97%. The bulk specific gravity was 0.47 g / ml, the degree of compression was 17%, and the angle of repose was 43 degrees.

Comparative Example 1 An oil-containing granular composition was prepared in the same procedure as in Example 1 except that 34 parts of Vitacel WF600 was used as the dietary fiber instead of Vitacel WF200. However, after 1 minute of stirring, it became porridge and not granular. From Example 1 and Comparative Example 1, it can be seen that even if fibrous dietary fiber has an average fiber length of less than 100 μm, the desired oil-containing granular composition cannot be obtained.

Comparative Example 2 Vitacell WF as dietary fiber was placed in the bowl of "Kenmix Mixer", a universal mixing machine manufactured by Aikosha Co., Ltd.
34 parts of 200 was added, 45 parts of lard flavored with soy sauce flavor and 18 parts of hardened palm oil were mixed, and these fats and oils melted at 50 ° C. were added, and after stirring at a beater rotation speed of 150 rpm for 7 minutes, oil QS was set to 3 Part of the mixture was added, and the mixture was stirred at the same rotation number for 2 minutes. After stirring, sieving was carried out in the same manner as in Example 1 to obtain an oil-containing granular composition. In the obtained oil-containing granular composition, the melting point of the oil / fat after formulation was 43 ° C., the weight ratio of the oil / fat to dietary fiber was 1.9, and the oil / fat content in the entire composition was 63% by weight. The obtained oil-containing granular composition had a good result in the crystallization test and a good result in the blocking test. The yield of the composition obtained is 82%,
Bulk specific gravity is 0.39 g / ml, compressibility is 29%, angle of repose is 5
It was 0 degrees. From Example 1 and Comparative Example 2, the oil-containing granular composition obtained by dry stirring granulation with a stirring granulator having a stirring blade and a crushing blade was obtained by dry stirring granulation with a universal stirring mixer. It can be seen that the yield, the bulk specific gravity, the compression degree, and the angle of repose are higher than those of the obtained oil-containing granular composition. That is, in order to efficiently obtain an oil-containing granular composition having desirable physical properties, dry stirring granulation using a stirring granulator having a stirring blade and a crushing blade is effective.

Example 2 37 parts of Vitacel WF200 as dietary fiber was put in a high-speed stirring granulator "Heavy Duty Type NMG-10L" manufactured by Nara Machinery Co., Ltd., and 45 parts of lard and coconut-flavored lard and palm. These oils and fats which were mixed with 18 parts of hardened oil and melted at 50 ° C were added, and the stirring blade rotation speed was 150 rp.
m Crushing blade rotation speed was 3000 rpm for 7 minutes. After stirring, the granules passing through the 8-mesh screen were collected. Thus, an oil-containing granular composition was obtained. In the obtained oil-containing granular composition, the melting point of the mixed fats and oils was 43 ° C., the weight ratio of the fats and oils to the dietary fiber was 1.7, and the content of the fats and oils in the entire composition was 63% by weight. The obtained oil-containing granular composition had a good result in the crystallization test and a good result in the blocking test. The proportion (yield) of the granules discharged from the machine that could pass through the 8 mesh sieve was 95%. The bulk specific gravity was 0.42 g / ml, the degree of compression was 19%, and the angle of repose was 47 degrees. From Example 1 and Example 2, when the oil-absorbent powder was added after granulation and stirred again, an oil-containing granular composition having a higher specific gravity, a lower compressibility and a smaller angle of repose was obtained, as compared with the case where it was not stirred. can get.

Example 3 A mixed powder of 25 parts of Vitacell WF200 / 9 parts of oil QS as an oil-absorbing material was put into a high-speed stirring granulator "Heavy duty type NMG-10L" manufactured by Nara Machinery Co., Ltd. 45 parts of lard and hardened palm oil 1
Add 8 parts of these oils and fats melted at 50 ° C., add stirring blade rotation speed 150 rpm, crushing blade rotation speed 3000 r
After stirring for 7 minutes at pm, 3 parts of oil QS was added, and stirring was continued for another 2 minutes at the same rotation speed. After stirring, the granules passing through the 8-mesh sieve were collected to obtain an oil-containing granular composition. In the obtained oil-containing granular composition, the melting point of the oil / fat after formulation was 43 ° C., the weight ratio of the oil / fat to dietary fiber was 2.5, and the oil / fat content in the entire composition was 63% by weight. The obtained oil-containing granular composition had a good result in the crystallization test and a good result in the blocking test. The proportion (yield) of the granules discharged from the machine that could pass through the 8 mesh sieve was 94%. The bulk specific gravity was 0.46 g / ml, the degree of compression was 17%, and the angle of repose was 44 degrees. As shown in Example 3, the average fiber length is 100 μm
It is also possible to use dietary fibers having the above fiber length in combination with other materials.

Comparative Example 3 Oil QS was used in place of Vitacel WF200 as the oil absorbing material.
An attempt was made to prepare an oil-containing granular composition in the same procedure as in Example 1 except that 4 parts were used. However, after 1 minute of stirring, it became sherbet-like and not granular.

Comparative Example 4 Avicel FD10 instead of Vitacel WF200 as dietary fiber
Preparation of an oil-containing granular composition was attempted by the same procedure as in Example 1 except that 34 parts of 1 was used. However, after 1 minute of stirring, it became porridge-like and not granular. From Comparative Example 4, it can be seen that dietary fibers having a porous average fiber length of 100 μm or less cannot be used alone.

COMPARATIVE EXAMPLE 5 As dietary fiber, Vitacell WF200 was replaced with Selfur # 200.
An attempt was made to prepare an oil-containing granular composition by the same procedure as in Example 1 except that 34 parts of was used. However, after 1 minute of stirring, it became porridge-like and not granular. From Comparative Example 5, it can be seen that dietary fibers having a porous average fiber length of 100 μm or more cannot be used alone.

Comparative Example 6 5 parts of Vitacel WF200 and 29 parts of oil QS as an oil-absorbing material were put in a high-speed stirring granulator "Heavy Duty Type NMG-10L" manufactured by Nara Machinery Co., Ltd. and put on a soy sauce flavor. 45 parts of scented lard and 18 parts of hardened palm oil were mixed and these fats and oils melted at 50 ° C. were added, and granulation was tried at a stirring blade rotation speed of 150 rpm and a crushing blade rotation speed of 3000 rpm. However, after 1 minute of stirring, it became a paste and not a granule. At this time, the melting point of the mixed fats and oils was 43 ° C, and the weight ratio of the fats and oils to the dietary fiber was 1
2.6, the content of fats and oils in the whole composition was 65% by weight. From Comparative Example 6, it is fibrous and the average fiber length is 100 μm.
It can be seen that even when a dietary fiber of m or more is used, when the weight ratio of the fats and oils to the dietary fiber exceeds 12, it becomes a paste at the time of granulation and a granular one cannot be obtained.

Comparative Example 7 The oil and fat used in Example 1 was replaced with the extremely hardened palm oil, and 6
An oil-containing granular composition was obtained by the same procedure as in Example 1 except that 63 parts of extremely hardened palm oil dissolved at 5 ° C was used and the inside of the stirrer was kept at 65 ° C. At this time, the melting point of oil is 59
C., the weight ratio of fats and oils to wheat fiber was 1.9, and the fats and oils content of the entire composition was 63% by weight. The blocking test evaluation of the obtained composition was ⊚, but the crystallization test evaluation was ×, and oil and fat crystals were precipitated on the surface of the hot water, and white solid fat was suspended. From Comparative Example 7, it can be seen that when the melting point of fats and oils is higher than 55 ° C., when the obtained composition is dissolved in hot water, precipitation of crystals is likely to occur.

Comparative Example 8 34 parts of Vitacell WF200 as dietary fiber were placed in a high-speed agitating and granulating machine "Heavy Duty Type NMG-10L" manufactured by Nara Machinery Co., Ltd., and 45 parts of lard flavored with soy sauce and palm. These fats and oils mixed with 35 parts of hardened oil and melted at 50 ° C were added, and the stirring blade rotation speed was 150 rp
m After stirring for 7 minutes at a rotation speed of 3000 rpm of a crushing blade, 3 parts of Oil QS (manufactured by Nitto Kagaku Co., Ltd.) was added, and the mixture was further stirred at the same rotation speed for 2 minutes. After stirring, the granules passing through the 8-mesh sieve were collected to obtain an oil-containing granular composition. In the obtained oil-containing granular composition, the melting point of fats and oils was 45 ° C., the weight ratio of fats and oils to dietary fiber was 2.4, and the content of fats and oils in the entire composition was 80% by weight. The crystallization test evaluation of the obtained composition was ◯, but the blocking test evaluation was ×, and blocking was observed. From Comparative Example 8, the oil and fat content in the entire oil-containing granular composition was 75%.
It can be seen that blocking is likely to occur when the value is larger than.
