Description

[Technical field]

[0001] The present invention relates to a defatted rice bran flour-containing powder composition. [Background technology]

[0002] Rice bran is known to be rich in functional ingredients such as γ-oryzanol, inositol, B vitamins, minerals, and dietary fiber, and attempts have been made to utilize it by incorporating it into oral compositions aimed at preventing lifestyle-related diseases, providing nutrition, etc. Typical oral compositions containing rice bran are beverages and puffed foods, but a granular composition has been proposed that can be dispersed in liquid foods to make it easier to incorporate into daily meals (Patent Document 1).

[0003] On the other hand, calcium is said to be the nutrient most lacking in Japanese people, and the deficiency is particularly noticeable among middle-aged and elderly people. Because calcium is a nutrient that cannot be obtained without daily intake, calcium carbonate is widely used to fortify foods with calcium.

[0004] As described above, the nutrients in rice bran are desirable nutrients for preventing lifestyle-related diseases that cause vascular diseases, which account for a large proportion of deaths among Japanese people, and calcium is desirable for preventing osteoporosis in the elderly. Therefore, there was a demand for a powder composition that could be easily dispersed in liquid foods and beverages, which would allow these nutrients to be ingested simultaneously and easily.

[0005] [Patent Document 1] JP 2004-65236 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, when defatted rice bran powder is mixed with calcium carbonate, the dispersibility of the powder composition in water decreases, and the time required for complete dispersion increases, resulting in reduced convenience during use. [Means for solving the problem]

[0007] The present inventors have conducted intensive research in light of the above problems and have surprisingly found that by further blending a monosaccharide with a powder composition containing defatted rice bran powder and calcium carbonate, the dispersion time of the powder composition in water can be shortened.

[0008] The present invention includes, for example, the inventions described below. Section 1. A powder composition containing defatted rice bran powder, calcium carbonate, and monosaccharides. Section 2. Item 2. The powder composition according to item 1, wherein the monosaccharide is at least one selected from the group consisting of glucose, fructose, and galactose. Section 3. Item 3. The powder composition according to item 2, comprising 1 to 50 parts by mass of the calcium carbonate and 5 to 150 parts by mass of the monosaccharide relative to 100 parts by mass of the defatted rice bran powder. Effect of the Invention

[0009] To provide a defatted rice bran-containing powder composition which contains defatted rice bran powder and calcium carbonate, but disperses in water in a short time, and is highly convenient. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Each embodiment included in the present invention will be described in more detail below. The present invention preferably includes a powder composition, particularly a powder composition containing defatted rice bran powder, calcium carbonate, and monosaccharides (hereinafter, sometimes referred to as the "powder composition of the present invention"). However, the present invention is not limited thereto, and includes all of the embodiments disclosed in the present specification that can be recognized by a person skilled in the art.

[0011] The defatted rice bran used in the present invention is rice bran defatted until the lipid content is 5 to 15% by mass. The rice bran used for defatting is the pericarp, seed coat, episperm, aleurone layer, etc. of brown rice, and by-products produced when brown rice is polished (whitened) to produce white rice can be used. Rice bran obtained by polishing (raw rice bran) usually contains about 18 to 20% by mass of lipids, and since oxidation of oil by lipase proceeds rapidly, it is preferable to subject the raw rice bran to lipase inactivation treatment as soon as possible after production. The inactivation treatment is generally performed by heating raw rice bran at about 70 to 130°C, and such known lipase inactivation treatment can be applied in the present invention. In addition, for example, a cooking device, a dry extruder, a wet extruder, a steam treatment device, etc. can be used for the heat treatment. Heat-treated rice bran is commercially available, and such commercially available products can also be used in the present invention. In addition, before the heat treatment, a preliminary drying process may be performed in which raw rice bran is dried to reduce the moisture content and prepare dried rice bran (for example, moisture content of about 5 to 10% by mass).

[0012] The rice bran is defatted by mechanical squeezing. The squeezing method used in the squeezing method is known, and an example of such a method is squeezing rice bran that has been heat-treated to about 100 to 115°C with a low-temperature continuous squeezing machine (for example, the Miracle Chamber sold by Technosigma Co., Ltd.). The present invention is not limited to this method, and any known squeezing method can be applied. The degree of squeezing is such that the lipids in the defatted rice bran after squeezing are 5 to 15% by mass, preferably 10 to 15% by mass.

[0013] The defatted rice bran obtained by squeezing and degreasing until the lipid content is 5 to 15% by mass can be further pulverized and classified to obtain finely pulverized defatted rice bran having an average particle size of 10 μm or less, preferably 30 μm or less. A known pulverization method can be used, for example, a cyclone mill, a jet mill, a hammer mill, a pin mill, a roller mill, a stone mill, a disk mill, etc. In the present invention, the average particle size of the defatted rice bran powder means the median size. The average particle size of the defatted rice bran powder can be measured using a laser diffraction / scattering particle size distribution analyzer MT3300 (manufactured by NIKKISO Co., Ltd.) using water as a dispersant. Finely pulverized defatted rice bran having a particle size distribution in which 90% or more pass through a mesh with a pore size of 30 μm is preferable because it improves the feel during and after drinking.

[0014] The defatted rice bran may be a commercially available product, such as "Hybref" or "Neohybref" manufactured by Sunbran Co., Ltd., which is a compressed defatted rice bran powder.

[0015] The defatted rice bran powder used in the present invention can be contained in an amount of about 30 to 80% by mass based on the total amount of the composition. The upper or lower limit of the range of the content may be, for example, 35, 40, 45, 50, 55, 65, 71, 72, 73, 74, 75, 76, 77, 78, 79, or 79% by mass. For example, the range is more preferably 60 to 80% by mass, or 70 to 80% by mass.

[0016] Examples of calcium carbonate used in the present invention include synthetic calcium carbonate, natural calcium carbonate (ground calcium carbonate), etc. The calcium carbonate is preferably natural calcium carbonate.

[0017] The synthetic calcium carbonate is not particularly limited, and examples thereof include precipitated (colloidal) calcium carbonate and light calcium carbonate. Synthetic calcium carbonate can be produced, for example, by reacting calcium hydroxide with carbon dioxide. Calcium hydroxide can be produced, for example, by reacting calcium oxide with water. Calcium oxide can be produced, for example, by co-firing limestone ore with coke. In this case, carbon dioxide is generated during firing, and calcium carbonate can be produced by reacting this carbon dioxide with calcium hydroxide.

[0018] Natural calcium carbonate is obtained by crushing naturally occurring calcium carbonate ore, shells, eggshells, etc., by a known method. Methods for crushing these include crushing methods using a roller mill, a high-speed rotating mill (impact shear mill), a container-driven media mill (ball mill), a media stirring mill, a planetary ball mill, a jet mill, etc. It is preferable that the natural calcium carbonate is calcium carbonate derived from shells.

[0019] Shell-derived calcium carbonate used in the present invention can be obtained from shellfish that are consumed in large quantities as edible shellfish meat, and most of which are industrial waste without being used, and is not particularly limited as long as it is a bivalve. In particular, shells belonging to the bivalve class Gliobranchidae, Pectinidae (e.g., scallop), Eubranchidae, Stromidae (e.g., clam), Heterodontidae, Lucinae (e.g., lunulae), Malidae (e.g., purple cockle), Veneridae (e.g., Miss clam), Bivalviae (e.g., giant ant shell), Salicidae (e.g., spoon shell), and Bivalviae (e.g., giant clam) are preferred, which are characterized by a light-colored shell surface, no shell skin, or a translucent shell skin, a relatively thick shell, and no scale-like shell. There is no particular restriction on where the shellfish may be harvested, but it is preferable to use shellfish that are safe and do not pose any problems, such as being harvested from a place where marine pollution is not advanced and heavy metals, arsenic, etc. have not accumulated in the flesh or shells.

[0020] To obtain calcium carbonate derived from shells, for example, first, in order to remove the adductor muscles, organic substances, and inorganic substances adhering to the shell raw material, it is immersed in hot water and shaken. If necessary, cleaning is performed with a wire brush or the like, or ultrasonic cleaning is carried out. When the adhesion of the adductor muscle or the like is strong, use the one that has been previously immersed in water. After removing the adductor muscles, organic substances, and inorganic substances adhering to the shell raw material, natural drying or forced drying is performed to evaporate the moisture. The shell from which the moisture has been removed is roughly pulverized to about 3 to 5 mm using a feather mill, a hammer mill (both manufactured by Hosokawa Micron Corporation), etc., and then finely pulverized to the target particle size (1 to 200 μm, preferably 5 to 100 μm, more preferably 10 to 80 μm) using an ACM (manufactured by Hosokawa Micron Corporation), a Cosmo Micronizer (manufactured by Nara Machinery Co., Ltd.), etc. to obtain shell powder. The obtained shell powder can be used as calcium carbonate derived from shells as it is, and if necessary, it can also be further sized, granulated, etc. for use.

[0021] The calcium carbonate used in the present invention can be contained in an amount of 1 to 50 parts by mass with respect to 100 parts by mass of defatted rice bran powder. The upper or lower limit of the range of the parts by mass may be, for example, 4, 6, 7, 8, 9, 10, 15, 20, 25, 35, 40, or 45 parts by mass. For example, the range is more preferably 5 to 25 parts by mass, or 10 to 20 parts by mass.

[0022] The calcium carbonate used in the present invention can be contained in an amount of about 0.3 to 40% by mass with respect to the total amount of the composition. The upper or lower limit of the range of the content may be, for example, 1, 2, 4, 6, 7, 8, 9, 10, 11, 12, 13, 14, 25, or 35% by mass. For example, the range is more preferably 3 to 20% by mass, or 5 to 15% by mass.

[0023] Examples of monosaccharides used in the present invention include glucose, psicose, ribose, deoxyribose, mannose, rhamnose, galactose, xylose, arabinose, fructose, fucose, ribulose, allose, xylulose, etc., and more preferably glucose, fructose, or galactose. These monosaccharides may be used alone or in combination of two or more.

For example, the range is more preferably 10 to 100 parts by mass, or 15 to 30 parts by mass.

[0025] The monosaccharides used in the present invention can be contained in an amount of about 1.5 to 70% by mass based on the total amount of the composition. The upper or lower limit of the range of the content may be, for example, 2, 3, 4, 6, 7, 8, 9, 11, 12, 13, 14, 15, 16, 17, 18, 19, 25, 35, 40, 45, 50, 55, 60, or 65% by mass.

EXAMPLES

[0036] The present invention will be described in detail below based on examples, but the present invention is not limited to these examples.

[0037] [Evaluation of dispersibility of powder composition in water] The powder compositions of Examples 1 to 10 and Comparative Examples 1 to 5 were prepared in the usual manner with the blending amounts shown in Tables 1 and 2. 100 ml of distilled water at room temperature and a stir bar of φ8×30 mm were placed in a 200 ml glass beaker and stirred at 850 rpm. 5 g of each powder composition was dropped into the center of the stirring vortex in the stirred distilled water at once, and the time until the powder was completely dispersed in the water was measured. The time until complete dispersion was defined as the time until the powder composition disappeared from the water surface. The test was performed four times for each powder composition, and the average values ​​are shown in Tables 1 and 2.

[0038] More than 90% of the defatted rice bran powder used in the test was finely ground to a particle size of 30 μm or less. Additionally, the shell-derived calcium carbonate and calcium carbonate powders used had an average particle size of 46 μm or less. Glucose, fructose, galactose, maltose, sucrose, trehalose, lactose, and erythritol were all powders manufactured by Nacalai Tesque.

[0039] [Table 1]

[0040] [Table 2]

[0041] As shown in Examples 1 and 8 in Table 1, when shell-derived calcium carbonate or only calcium carbonate was added to defatted rice bran powder (A+B), the time required for dispersion was longer than that required for defatted rice bran powder alone as shown in the Reference Example. However, by further adding glucose, a monosaccharide (A+B+C), the time required for dispersion was significantly reduced.
