  The technique according to Patent Document 1 is a technique that focuses on the structure of collagen peptide powder and sedimentation solubility, but the technique is limited to the case of using a collagen peptide powder having a specific structure. It is not excellent in terms.

In addition, when a powder composition is granulated using a material containing a large amount of fine particles such as collagen peptide (hereinafter referred to as “fine material” as appropriate), it is finer than when no fine material is used. Many powders (including not only single fine particles but also powders not granulated to a desired size) are generated. Such a fine powder instantly absorbs the liquid when the liquid is added to generate a viscosity, and thus prevents the liquid from diffusing and penetrating into the entire powder composition.
Therefore, the fine powder in the powder composition decreases the solubility of the powder composition as a whole in the liquid.

That is, according to the method for producing a powder composition according to the present invention, it is possible to produce a powder composition with a reduced proportion of fine powder.

It is a flowchart explaining the manufacturing method of the powder composition which concerns on one Embodiment of this invention.

Hereinafter, the form (embodiment) for enforcing the manufacturing method of the powder composition concerning the present invention is explained.
First, the powder composition produced by the method for producing a powder composition according to this embodiment, the raw materials used in the method for producing a powder composition according to this embodiment, and the binder liquid will be described.

[Powder composition]
The powder composition produced by the method for producing a powder composition according to the present embodiment is a granular composition formed by granulating raw materials such as fine materials and adsorbed oil / fat powder.
The powder composition may be dissolved in a liquid such as hot water, water or juice and used as a drink, or may be used as a food such as jelly, and can be used as various foods and drinks. It is.
Furthermore, the use of the powder composition is not limited to food and drink, and can be widely used without limitation as long as it is a granular composition such as pharmaceuticals, supplements, cosmetics, bathing agents, and the like. .

[material]
The raw material used in the manufacturing method of the powder composition which concerns on this embodiment contains a fine material and adsorption fat and oil powder. In addition, the raw material may contain materials other than the fine material and the adsorbed oil / fat powder in order to obtain the various types of powder compositions described above.

(Fine material)
The fine material is a fine material containing 60% by mass or more of particles having a particle size of 250 μm or less.
In the case of using a fine material as a raw material, the method for producing a powder composition according to the present embodiment includes fine powder (including not only single fine particles but also powder not granulated to a desired size). ) Is often solved. Therefore, among the fine materials, those containing 60% by mass or more of particles having a particle size of 250 μm or less in which the above-mentioned problems clearly appear were targeted. The target fine material preferably contains 80% or more of particles having a particle size of 250 μm or less in which the above-described problems appear more remarkably.

The ratio of particles having a particle size of 250 μm or less can be measured by a vacuum suction type sieving device (Air Jet Sieve manufactured by Hosokawa Micron).
The fine material corresponds to a material containing a particle having a particle size of 250 μm or less among the raw materials such as foods and drinks, pharmaceuticals, supplements, cosmetics, and bathing agents, specifically, a collagen peptide. And dietary fiber.

The collagen peptide is a product obtained by degrading collagen by enzymatic treatment or the like to lower the molecular weight. Dietary fiber is a high-molecular component mainly composed of polysaccharides in foods that are not digested by human digestive enzymes. For example, indigestible dextrin, polydextrose, cellulose, pectin, hemicellulose, lignin, glucose Mannan, β-glucan and the like can be mentioned.
In addition, it does not specifically limit regarding the substance from which a collagen peptide or dietary fiber originates, or a manufacturing method.

(Adsorbed oil powder)
The adsorbed fat / oil powder is a powder obtained by mixing a base material and fat / oil.
Here, the base material is starch, starch hydrolyzate, glucose, or the like (one or more of them). And a starch hydrolyzate is what hydrolyzed starch, for example, dextrin, maltose, an oligosaccharide etc. can be mentioned.
Oils and fats are esters of fatty acids and glycerin, such as salad oil, corn oil, soybean oil, sesame oil, palm oil, coconut oil, olive oil, etc. (one or more of these). Mention may be made of fatty oils.

Unlike the spray-dried product, the adsorbed fat / oil powder is not subjected to aggressive drying (for example, spray drying), but passive drying (for example, natural drying during storage) is allowed. The
Further, the adsorbed oil / fat powder may contain, for example, an emulsifier, a saccharide, an antioxidant, an anti-caking agent and the like in addition to the base material and the oil / fat.

Conventionally, this adsorbed fat and oil powder has been recognized by those skilled in the art as having the disadvantage that the fluidity is poor because the surface of the powder has oil bleeding and the adhesion and cohesion between the powders is high.
However, the present inventors have found that the adsorbed oil and fat powder exhibits a remarkable effect of enabling proper granulation by capturing fine materials due to the characteristics that have been recognized as drawbacks, in other words, The present invention has been completed by discovering that it is possible to solve a peculiar problem (a problem of “suppressing generation of fine powder”) that occurs when a powder composition is granulated using a fine material.

(Adsorbed oil / fat powder: content of fat / oil with respect to adsorbed oil / fat powder)
The content of fat / oil with respect to the adsorbed fat / oil powder (specifically, the mass of fat / oil in the adsorbed fat / fat powder / the mass of adsorbed fat / oil powder × 100) is preferably 10.0 to 50.0% by mass, more preferably 30% by mass or more. Preferably, 40 mass% or more is particularly preferable.
If the content of the fat / oil with respect to the adsorbed fat / oil powder is less than the predetermined value, the base material in the adsorbed fat / oil powder embraces the fat / oil, thereby weakening the force of capturing the fine material of the adsorbed fat / oil powder, Generation of fine powder cannot be efficiently suppressed. On the other hand, if the content of the fat / oil with respect to the adsorbed fat / oil powder exceeds a predetermined value, the viscosity of the adsorbed fat / oil powder increases, and the fluidity during granulation is deteriorated.

(Adsorbed oil / fat powder: content of oil / fat with respect to raw material)
The content of fat / oil with respect to the raw material (specifically, the mass of fat / oil in the adsorbed fat / fat powder / the mass of the raw material × 100) is preferably 0.40 to 4.0% by mass, more preferably 1.2% by mass or more, 2.0 mass% or less is especially preferable.
When the content of fats and oils with respect to the raw material is less than a predetermined value, the content of fats and oils with respect to the entire raw material cannot be sufficiently ensured, and as a result, generation of fine powder cannot be efficiently suppressed. On the other hand, if the content of fats and oils relative to the raw material exceeds a predetermined value, the amount of fats and oils is large, the viscosity of the raw material as a whole becomes high, and fluidity during granulation is deteriorated.

(Adsorbed oil / fat powder: content of adsorbed oil / fat powder with respect to raw materials)
The content of the adsorbed oil / fat powder with respect to the raw material (specifically, the mass of the adsorbed oil / fat powder / the mass of the raw material × 100) is preferably 1.0 to 10.0% by mass, more preferably 3.0% by mass or more. 0.0 mass% or less is particularly preferable.
When the content of the adsorbed oil / fat powder with respect to the raw material is less than the predetermined value, the amount of adsorbed oil / fat powder capturing the fine material decreases, and as a result, generation of fine powder cannot be efficiently suppressed. On the other hand, if the content of the adsorbed oil / fat powder with respect to the raw material exceeds a predetermined value, the amount of adsorbed oil / fat powder is large, the viscosity of the entire raw material is increased, and the fluidity during granulation is deteriorated.

(Other materials)
As a raw material, you may contain materials other than a fine material and adsorbed fats and oils powder.
For example, when producing a granular composition for soup by the method for producing a powder composition according to the present embodiment, other materials include corn powder, potato powder, onion powder, chicken powder, whey powder, Examples thereof include granulated sugar, salt, processed starch, emulsified oil / fat powder (spray-dried product), guar gum and the like.
Moreover, what is necessary is just to contain the well-known material in each field | area when manufacturing the granular composition for pharmaceuticals, a supplement, cosmetics, and a bath agent.

[Binder liquid]
The binder liquid used in the method for producing a powder composition according to this embodiment is a solution having a function of adhering raw materials to each other during granulation.
And as the binder liquid, for example, pullulan, guar gum, gum arabic, locust bean gum, trehalose, gelatin, dextrin, sodium alginate, various starches, a solution in which one or more sugars are dissolved, water, and And ethanol.

Among these binder liquids, it is preferable to use a binder liquid containing pullulan. This is because inclusion of pullulan in the binder liquid can suppress collapse of the granular composition during drying and cooling after granulation (specifically, after spraying the binder liquid during granulation).
Here, pullulan is a kind of polysaccharide consisting only of glucose, and is a compound having a structure in which maltotriose in which three molecules of glucose are linked by α-1,4 bonds is linked by α-1,6 bonds.
And when pullulan is contained in the binder liquid, it is preferably contained in an amount of 0.1 to 10% by mass, and in order to sufficiently obtain the above-described effect, it is more preferably contained in an amount of 1.0% by mass or more. In order to avoid a decrease in handleability due to being too high, it is particularly preferable to contain 5.0% by mass or less.

  In addition, as for each material of an above-mentioned raw material, the pullulan etc. which are contained in a binder liquid, what is generally marketed can be used.

[Production method of powder composition]
Next, the manufacturing method of the powder composition which concerns on this embodiment is demonstrated.
As shown in FIG. 1, the manufacturing method of the powder composition which concerns on this embodiment may include granulation process S1, and may include preparatory process S0 before granulation process S1.

  In the preparation step S0, a raw material and a binder liquid are prepared. For example, the adsorbed oil and fat powder to be contained in the raw material and the binder liquid are prepared.

In the granulation step S1, the powder composition is granulated by spraying the binder liquid onto the raw material.
About the granulation method in granulation process S1, it does not specifically limit, such as fluid bed granulation, stirring granulation, rolling granulation. However, among these granulation methods, a fluidized bed structure in which the raw material is fluidized by blowing hot air from below the tank, and the powder composition is granulated by spraying the binder liquid from above or from the peripheral wall portion of the tank. Granules are preferred. The fluidized bed granulation is, in detail, a step of spraying the binder liquid while blowing hot air, a step of stopping spraying and blowing hot air, and a step of cooling by blowing cold air (or room temperature air). And can be divided into
And it does not specifically limit about the granulation apparatus used in granulation process S1, What is necessary is just to use a well-known granulation apparatus.

  The detailed granulation phenomenon in the granulation step S1 is not clear, but the adsorbed oil / fat powder (particularly the oil / fat in the adsorbed oil / fat powder) captures the fine material and the desired size by the binder liquid It is considered that the generation of fine powder (including not only single fine particles but also powder that has not been granulated to a desired size) is suppressed.

  In the method for producing a powder composition according to the embodiment of the present invention, the conditions that are not explicitly specified may be any conventionally known conditions, and are not limited as long as the effects obtained by the conditions are exhibited. Needless to say.

Next, the production method of the powder composition according to the present invention will be described by exemplifying examples that satisfy the requirements of the present invention and comparative examples that are not.
First, in Example 1, it confirms about the influence which the presence or absence of adsorption | suction fats and oils powder has on the fine powder rate (content rate of fine powder).

[Preparation of raw materials and binder liquid]
Each material shown in Table 1 was prepared as a raw material. A collagen peptide containing 82% of particles having a particle size of 250 μm or less was used, and a dietary fiber (digestible dextrin) containing 87% of particles having a particle size of 250 μm or less was used. In addition, the raw material shown in Table 1 is a raw material supposing manufacture of the powder composition for potato soup.
Moreover, 4% pullulan solution (Pullan: Hayashibara Co., Ltd., food additive pullulan) was prepared as a binder liquid.

[Granulation conditions]
Granulation was performed under the following conditions. In addition, granulation is performed in a binder liquid spraying process (hot air blowing + binder liquid spraying: about 12 minutes) → drying process (hot air blowing: about 10 minutes) → cooling process (air blowing at substantially normal temperature after stopping the heater) : About 5 minutes).
Input amount of raw material to fluidized bed granulator: 750 g
Hot air temperature (binder liquid spraying process / drying process): 95 ° C
Air volume of hot air (binder liquid spraying process / drying process): 0.4 L / min Total amount of binder liquid sprayed (binder liquid spraying process): 100 mL
Binder liquid spraying speed (binder liquid spraying process): 7.5 mL / min Air flow rate at substantially room temperature (cooling process): 0.4 L / min

[Test content: Measurement of fines ratio]
The fine powder ratio of the powder composition was measured using a vacuum suction type sieving device (manufactured by Hosokawa Micron Corporation, air jet sieve e200LS, measurement conditions; suction pressure 3200 Pa, 2 minutes).
Collagen peptide absorbs the binder liquid and is easy to hold, making it difficult to granulate other materials in the raw material, and it takes time to dry the held water, so it can be pulverized during drying and cooling. It tends to move forward.
In Example 1, since a sample containing a large amount of collagen peptide is also targeted, the fine powder rate of Example 1 is “amount of 150 μm pass” (content of powder passing through a filter hole diameter of 150 μm). As a reference, it can be determined that the smaller the fine powder rate, the higher the effect (the effect of suppressing the generation of fine powder).

Table 1 below shows the raw materials and test results of each sample.
In addition, “content of powder with respect to raw material” in the table means “mass of adsorbed oil / fat powder (or SD powder) / mass of raw material × 100” in detail, and “content of oil / fat with respect to powder” Means “mass of fat / oil in adsorbed fat / oil powder (or SD powder) / mass of adsorbed fat / oil powder (or SD powder) × 100”, and “content of fat / oil with respect to raw material” means “adsorbed fat / oil” "Mass of fat / oil in powder (or SD powder) / mass of raw material x 100".
In addition, “SD powder” in the table means “powder containing fats and oils pulverized by a spray drying method”.

[Examination of test results: Example 1]
Since Samples 1-1 to 1-5 used only the emulsified oil / fat powder (SD powder) without using the adsorbed oil / fat powder, the fine powder rate increased.
On the other hand, since samples 1-6 to 1-10 used adsorbed fats and oils powder, it was found that the fine powder rate can be greatly reduced when compared with samples 1-1 to 1-5, respectively.

  Furthermore, although samples 1-6 to 1-10 are changing the content of the collagen peptide that is a fine material, the fine material ratio is low no matter which result is confirmed. It has been found that the present invention can be effective regardless of whether the number is small or large.

  Sample 1-11 contained not only collagen peptide as a fine material but also dietary fiber, and sample 1-12 contained only dietary fiber as a fine material. In either case, the fine powder rate should be lowered. I was able to. From this result, it was found that the present invention is not limited to the case of targeting collagen peptides as a fine material, but can be applied to various fine materials as long as the material contains many particles having a small particle size. .

  Next, in Example 2, it confirms about the influence which the kind of binder liquid has on the fine powder rate.

[Preparation of raw materials and binder liquid]
Each material shown in Tables 2 and 3 was prepared as a raw material. A collagen peptide containing 82% of particles having a particle size of 250 μm or less was used, and a dietary fiber (digestible dextrin) containing 87% of particles having a particle size of 250 μm or less was used. In addition, the raw material shown in Table 2 is a raw material which assumed manufacture of the powder composition for corn potage, and the raw material shown in Table 3 is a raw material which assumed manufacture of the powder composition for potato soup.
In addition, 4% pullulan solution (pullulan: Hayashibara Co., Ltd., food additive pullulan) and 2% starch solution (starch: Matsutani Chemical Industries, Ltd., Matsunoline SM-32) were prepared as binder solutions.

[Granulation conditions]
Granulation was performed under the following conditions. In addition, granulation is performed in a binder liquid spraying process (hot air blowing + binder liquid spraying: about 22 minutes) → drying process (hot air blowing: about 10 minutes) → cooling process (air blowing at substantially normal temperature after stopping the heater) : About 5 minutes).
Raw material input to fluidized bed granulator: 1000 g
Hot air temperature (binder liquid spraying process / drying process): 95 ° C
Air volume of hot air (binder liquid spraying process): 0.5 L / min Air volume of hot air (drying process): 0.4 L / min Total amount of binder liquid sprayed (binder liquid spraying process): 200 mL
Binder liquid spraying speed (binder liquid spraying process): 9.0 mL / min. Air flow rate at substantially room temperature (cooling process): 0.4 L / min.

[Test content: Measurement of fines ratio]
The particle size distribution of the powder composition is measured by overlaying five JIS standard sieves to provide a 50 g sample, and measuring the weight of the sample remaining on the mesh after sieving the overlapped JIS standard sieve back and forth and left and right It was done by doing.
In Example 2, “amount of 1000 μm on” (content of powder not passing through filter hole diameter of 1000 μm), “amount of 1000 μm pass, amount of 710 μm on”, “710 μm pass, amount of 500 μm on”, “500 μm pass, “Amount of 355 μm on”, “Amount of 355 μm pass, 250 μm on”, “Amount of 250 μm pass” were measured.

  Tables 2 and 3 below show the raw materials and test results of each sample.

[Examination of test results: Example 2]
Comparing Samples 2-1 and 2-2 and Samples 2-3 and 2-4, the use of a pullulan solution rather than the use of a starch solution as a binder solution indicates that both can lower the fine powder rate. I understood. Moreover, the result that not only the ratio of the fine powder but the ratio of the powder which is too coarse with respect to the samples 2-1 and 2-3 was obtained. From this, it was found that a granulated product having a uniform size can be obtained by using the pullulan solution.
In other words, even when using raw materials intended for the production of powder compositions for corn potage, even when using raw materials intended for the production of powder compositions for potato soup, pullulan solution It was found that a granulated product having a lower fine powder ratio and a uniform size can be obtained by using.

  In Example 2, the behavior of the powder composition during granulation was confirmed. When the starch solution was used (Samples 2-1 and 2-3) and when the pullulan solution was used (Sample 2- 2, 2-4), no significant difference was observed in the growth of granules during spraying of the binder liquid. However, when the pullulan solution was used (samples 2-2 and 2-4), it seemed that the granular composition collapsed less during drying / cooling after stopping spraying. Is considered to have an effect of suppressing the collapse of the granular composition.

  Next, in Example 3, it confirms about the influence which content of adsorption | suction fats and oils powder (fat) has on the fine powder rate.
