Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can be used for various foods and drinks, cosmetics, pharmaceuticals, etc., and has excellent storage stability and powder fluidity, and can be used in water. The present invention relates to a novel method for producing a powdered fat or oil that dissolves transparently when dissolved. [0002] Conventionally, methods for producing powdered fats and oils used for various foods and drinks, cosmetics, pharmaceuticals, etc. include, for example, a method of preparing a fat or oil from a protein solution such as gelatin or a processed starch solution such as dextrin. Or emulsify with excipients such as natural gum such as gum arabic, atomize by spraying droplets using pressure or centrifugal force in a drying room where hot air flows, and evaporate water in a short time and dry A spray drying method or the like for powdering is used. However, the 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. Is considerably limited. 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 such powders in foods and drinks requiring 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

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 according to the kind of fats and oils to be used.
Usually, about 10 parts by weight of fats and oils is
Suitably about 120 parts by weight, preferably in the range of 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 flowability are remarkably improved as compared with the conventional product. The method of adsorbing and holding the oils and fats is sufficient only by mixing a powdered base (granulated starch hydrolyzate) and the oils and fats, and can be prepared very easily. When the fats and oils are liquid, they can be used as they are, and when they are solid, they can be added to the powdered base after heating and dissolving the fats or oils, or by adding the 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 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 granulating with a fluid 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 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 powdery fats and oils thus obtained are excellent in storage stability and powder flowability, 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 cosmetics and pharmaceuticals. Etc. can also be used. The present invention will be described more specifically with reference to the following examples. (Example of preparation of powdered base) Using a fluidized bed granulator manufactured by Glatt, a guar gum 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 the various average particle sizes, particle size of 100 mesh pass, loose bulk density, and compressibility 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 properties of pine flow and oil cue (starch hydrolyzate manufactured by Nisseki Chemical Co., Ltd.) for comparison. [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. A 100-cc container having an inner diameter of 50 mmφ and a compressibility 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 with 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 degree of compression (C) is represented by the following equation (1). C [%] = (B−A) {B × 100} (1) After adding 100 g of hot water at 60 ° C. to 1 g of turbidity powdered oil and fat and dissolving it, 5 minutes later, measure the absorbance of the aqueous layer at a wavelength of 680 nm. I do. [Table 2] As is evident from Table 2, in each of the comparative examples, when the oil content was low, the powder fluidity was slightly good, but when the oil content was high, the base particles had a sticky surface and the fluidity was 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, 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 also stable in powder fluidity and flavor. According to the present invention, since fats and oils are mixed after granulation of starch hydrolyzate, fats and oils are not deteriorated by hot air in a granulator, storage stability and powder fluidity. Excellent,
It is possible to provide a method for producing powdered fats and oils which is transparently dissolved when dissolved in water and can be used for various foods and drinks, cosmetics, pharmaceuticals and the like.
