2. Description of the Related Art Conventionally, methods for producing powdered fats and oils used for various foods and drinks, cosmetics, pharmaceuticals, and the like include, for example, a method of preparing a fat or oil from a protein solution such as gelatin, a processed starch solution such as dextrin, or gum arabic. And emulsified with excipients such as natural gums, and atomized by spraying droplets using pressure or centrifugal force in a drying chamber where hot air flows, to evaporate water in a short time to form dry powder A spray drying method or the like is used. However, powdered fats and oils obtained by the spray-drying method, since the fats and oils are dried at a relatively high temperature during the manufacturing process, there is a possibility that the fats and oils may be colored, oxidized, deteriorated, deteriorated, etc. Of oils and fats is considerably restricted. In addition, since the emulsification treatment is performed during the manufacturing process, when the obtained powdered fats and oils are dissolved in water, turbidity is generated, and the use of the powdered fats and oils which is required to have transparency is limited. there were.

[0003] Various proposals have been made to solve the above-mentioned drawbacks. For example, an aqueous solution having a viscosity of 0 to 800 cP (30 ° C.) of a starch hydrolyzate having a DE of 18 or less is subjected to an internal pressure of 3 to

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail. The starch hydrolyzate that can be used in the present invention includes:
For example, it is obtained by hydrolysis of various starches such as sweet potato, potato, corn, cassava, wheat, rice and the like. The hydrolysis method can be carried out, for example, by using an appropriate acid, enzyme or both. The starch hydrolyzate of the present invention may be one prepared by the above method, but it is easily available on the market. For example, Pine Flow (manufactured by Matsutani Chemical Industry Co., Ltd.) and Oil Cue (manufactured by Nichiten Chemical Co., Ltd.) And the like.

In the present invention, the above-mentioned starch hydrolyzate is granulated, and the granulated starch hydrolyzate obtained by granulating into a specific range of particle size, particle size, loose bulk density and compressibility is powdered. The granulation method used as a base is, for example, a method of fluidized bed granulation while spraying an aqueous solution of a binder onto the starch hydrolyzate. Examples of the binder include gum arabic, xanthan gum, guar gum, potato starch, corn starch, gelatin, sodium alginate, and the like.
100-1000 cP, preferably 300-500 cP
Is appropriate. In order to obtain a powdered base having a particle size, particle size, loose bulk density and compressibility within a specific range, for example, as a condition of a fluidized bed granulator, an intake air temperature of 6
0-90 ° C, binder spray air pressure 1.0-2.0Kg / c
m ² , by granulating with a binder liquid content of 20 to 40% (based on the base) and a binder liquid viscosity of 500 cP, an average particle diameter of 200 to 1000 μm and a particle diameter of 100 mesh pass 3
A granulated product having 0% or less, a loose bulk density of 0.1 to 0.3 g / cm ³ and a degree of compression of 5 to 30% is obtained.

The granulated starch hydrolyzate used as a powdering base in the present invention has an average particle size of 200 to 1000 microns, a particle size of 100 mesh pass of 30% or less, and a loose bulk density of 0.1 to 0.3 g / cm. ^{3. The} degree of compression is in the range of 5 to 30%, preferably, the average particle size is 200 to 600 microns, the particle size is 100 mesh pass 25% or less, and the loose bulk density is 0.1.
Those having a range of 5 to 0.25 g / cm ³ and a degree of compression of 10 to 20% can be used. If a material that does not fall within this range is used, the powder fluidity, oil absorbing power, and storage stability will deteriorate, and turbidity will occur when dissolved in water.

According to the present invention, a starch hydrolyzate is granulated in a specific range of particle size, particle size, compressibility and loose bulk density, and then mixed with fats and oils as a powdering base. Thus, a powdered fat or oil obtained by adsorbing and holding a desired fat or oil is obtained. When such a powdered base is mixed with fats and oils, a powdered base usually used as required, for example, microcrystalline cellulose powder (Avicel (trade name, manufactured by Asahi Kasei Corporation))
), Soluble starch, processed starch, dextrin, soybean polysaccharide, lactose, glucose, calcium carbonate, tricalcium phosphate, silicon dioxide and the like.

The fats and oils mixed and adsorbed and held on the powdered base in the present invention may be liquid or solid fats and oils conventionally used in foods, cosmetics, pharmaceuticals and the like. For example, vegetable oils and fats such as soybean oil, sesame oil, peanut oil, corn oil, rapeseed oil, coconut oil, palm oil and their hardened oils; animal fats and oils such as tallow, lard, fish oil and the like, and butter; , Margarine, shortening and other processed oils and fats; Vitamin E, DHA, EPA,
Functional oils and fats such as linoleic acid, γ-linolenic acid, α-linolenic acid, evening primrose oil, borage oil, lecithin, octacosanol, γ-oryzanol; essential oils, flavor oils, oleoresins, natural flavors, synthetic flavors and their two. And oil-soluble flavors such as a mixture of more than one kind. These can be used alone or as a mixture of two or more.

The above fats and oils include commonly used antioxidants such as vitamin E, tea extract, green coffee bean extract, chlorogenic acid, spice extract, caffeic acid, rosemary extract, vitamin By appropriately mixing C palmitate, rutin, quercetin, bayberry extract and the like, deterioration of these fats and oils can be prevented.

The mixing ratio of the powdered base of the present invention and fats and oils is not strictly limited, and can be varied over a wide range depending on the kind of fats and oils to be used.
Normally, fats and oils are added in an amount of about 10 to 100 parts by weight of the powdered base.
A suitable range is about 120 parts by weight, preferably about 20 to about 100 parts by weight. According to the present invention, even when the mixing ratio of the fats and oils to the powdered base is 1: 1, the storage stability and powder fluidity are remarkably improved as compared with the conventional product.

The method for adsorbing and holding the fats and oils is sufficient only by mixing a powdered base (hydrolyzate of granulated starch) and fats and oils, and can be prepared very easily. When the fats and oils are liquid, they can be used as they are, or when the fats and oils are solid, they can be added to a powdered base after heating and dissolving the fats or oils, or by adding a powdered base to the fats and oils. Known as a mixer, for example, a ribbon mixer, a Nauta mixer, a vertical granulator, a drum mixer,
A high-speed stirring mixer, a pausing mixer, a universal mixer, a cake mixer, etc. can be used, and the mixing temperature is about 10 to about 6
By mixing at 0 ° C., preferably about 20 ° C. to about 50 ° C., for about 5 minutes to about 2 hours, preferably for about 30 minutes to about 1 hour, the desired powdered fat or oil can be easily obtained.

In a preferred embodiment of the method for preparing a powdered fat or oil according to the present invention, for example, a starch hydrolyzate obtained by granulation with a fluidized bed granulator, having an average particle size of 200 to 1000 microns and a particle size of To 100 g of a granulated product having a 100 mesh pass of 30% or less, a loose bulk density of 0.1 to 0.3 g / cm ³ and a degree of compression of 5 to 30%, 150 g of fats and oils is added at about 30 to 40 ° C. using a cake mixer. Mix for about 5 to 30 minutes to obtain a powdered fat. The powdered fats and oils thus obtained are excellent in storage stability and powder fluidity, and can be transparently dissolved in water. Powdered fats and oils obtained as described above include, for example, beverages, powdered beverages, desserts, chewing gum, tablet confections, snacks, processed marine products, processed meat, retort foods, foods and drinks such as soups, and further cosmetics and pharmaceuticals. Etc. can also be used.

[0017]

Next, the present invention will be described more specifically with reference to examples. (Example of preparation of powdered base) Using a fluidized bed granulator manufactured by Glatt, a guagum aqueous solution of 0.5% by weight was sprayed on 250 g of pine flow (starch hydrolyzate manufactured by Matsutani Chemical Industry Co., Ltd.). The granulation conditions were changed, and the powdered base (granulated material) No. having various average particle sizes, a particle size of 100 mesh passes, a loose bulk density, and a degree of compression shown in Table 1 was used. 1-4 were obtained. The granulation conditions were as follows: intake temperature 70 ° C., binder spray air pressure 1.5 kg
/ Cm ² and the binder spray amount is 55 g (No. 1), 7
0 g (No. 2), 90 g (No. 3), and 25 g
(No. 4). Table 1 also shows the characteristics of pine flow and oil cue (starch hydrolyzate manufactured by Nisseki Chemical Co., Ltd.) for comparison.

[0018]

[Table 1]

(Examples 1 to 9 and Comparative Examples 1 to 9) Each of the powdered bases of N0.1 to N4, pine flow and oil cue obtained in the above preparation examples, lard was added to 200 g each, and the oil content was 1 unit.
The mixture was mixed in a universal mixer at a temperature of 40 ° C. for 30 minutes so as to be 0, 30, and 50% by weight (11, 43, and 100 parts by weight, respectively, when the powdered base was 100 parts by weight). An oil was obtained. Table 2 shows the powder fluidity of each of the obtained powdered fats and oils and the transparency when dissolved in water. still,
The powder fluidity is indicated by the degree of compression. The smaller the value of the degree of compression, the better the fluidity.The transparency when dissolved in water is indicated by the turbidity, and the smaller the value of the turbidity, the higher the transparency. Is shown. The method of measuring the degree of compression and turbidity is described below.

Compressibility A 100-cc container having an inner diameter of 50 mmφ is loosely filled with powdered fat through a 10-mesh sieve from above, and the weight is measured to determine the loose bulk density (A). Then, a powdery fat is added to a container having the same diameter, and tapping is performed 180 times by a tapping device at a head of 18 mm. The frame is removed and the powder is ground at the upper edge of the container and weighed to obtain a consolidated bulk density (B). The compression degree (C) is represented by the following equation (1). C [%] = (B−A) {B × 100} (1) Turbidity 100 g of hot water at 60 ° C. was added to and dissolved in 1 g of powdered oil and fat, and after 5 minutes, the absorbance of the water layer was measured at a wavelength of 680 nm. I do.

[0021]

[Table 2]

As is clear from Table 2, in each of the comparative examples, when the oil content is low, the powder fluidity is slightly good, but when the oil content is high, the base particles have a sticky surface and the fluidity is low. Bad and turbid when dissolved in water. Therefore, even in the case of powdered fats and oils obtained by granulating a starch hydrolyzate which is commercially available as in Comparative Examples 1 to 3 (using powdered base No. 4), the powdered base is treated in a specific range. Unless the diameter, particle size, loose bulk density and degree of compression are set, the desired powdered fats and oils cannot be obtained. On the other hand, in each of the examples, even when the oil content was high, the fluidity was good, and the oil was transparently dissolved in water.

When the powdered fats and oils of the comparative examples and examples were stored at room temperature for one month, oil bleeding became severe in the comparative examples and the odor of the fats and oils deteriorated. It was stable in terms of powder fluidity and flavor.

[0024]

According to the present invention, fats and oils are mixed after granulation of a starch hydrolyzate, so that fats and oils are not deteriorated by hot air in a granulator, and have excellent storage stability and powder flowability.
It is possible to provide a method for producing powdered fats and oils that dissolves transparently when dissolved in water and can be used for various foods and drinks, cosmetics, pharmaceuticals, and the like.
