 Description Oil-containing granular composition and method for producing the same

 The present invention relates to an oil-containing granular composition which can be used in foods, pharmaceuticals, and cosmetics, has excellent blocking resistance, and when dissolved in hot water, oil droplets float on the surface of the hot water, and the crystallization of oil and fat after dissolution is slow. The present invention relates to a composition and a method for producing the composition. Background art

Conventional granulated compositions containing fats and oils have been mainly granulated powdered fats and oils obtained by spray-drying an emulsion composed of water, fats and oils, an emulsifier, starch and the like under a high-temperature atmosphere. In the granulation method, a method of granulating and drying under a high temperature atmosphere using an aqueous solution of a polysaccharide as a binder has been the mainstream. However, in these methods for producing and granulating powdery fats and oils, a drying step at a high temperature is indispensable, so that not only fats and oils are severely degraded but also when flavored fats and oils are used. Had a problem that the flavor deteriorated and the flavor components volatilized and the flavor was weakened. Further, when the heat-sensitive active ingredient is converted into a capsule, there is a problem that the required active ingredient is decomposed or the properties of the active ingredient are reduced. Furthermore, since the emulsions are spray-dried powders / granular fats and oils, the fats and oils are emulsified with the hot water when dissolved in hot water, and there is a problem that the taste of the fats and oils is not easily felt when eating and drinking. In order to solve the above-mentioned problem, Japanese Patent Application Laid-Open No. Sho 62-274430 proposes a method of producing granular fats and oils by mixing and stirring fats and oils, a base material for containing fats and oils, and a polyol. I have. JP-A-10-095992 proposes a method of granulating a starch hydrolyzate and then absorbing the oil in a temperature range above the melting point of the fat to produce a powdered fat. In Japanese Patent Application Laid-Open No. 7-284430, Japanese Patent Application Publication No. 7-284430 discloses a method for producing a granular oil-containing food by heating and mixing solid fat, a food material other than oil and fat, and a starch-decomposed product in a temperature range not lower than the melting point of solid fat. After that, a method of producing a granular oil-containing food by cooling to a temperature below the melting point of the solid fat has been proposed. However, these methods have not been able to sufficiently increase the fat content. Therefore, it is necessary to add a large amount of the above-mentioned granular fats and oils in order to impart richness and flavor of the fats and oils to the granular / powdered instant soup and the like, leading to an increase in cost and a problem in versatility. Was. Disclosure of the invention

 The present invention relates to an oil-containing granular composition which can be used in foods, pharmaceuticals, and cosmetics, has excellent blocking resistance, and when dissolved in hot water, oil droplets float on the surface of the hot water, and the crystallization of oil and fat after dissolution is slow. It was intended to provide a composition and a method for producing the composition.

 Means for Solving the Problems The present inventors have made intensive studies in order to solve the above problems, and as a result, completed the present invention.

That is, the present invention relates to a composition comprising dietary fibers and fats and oils. A method for producing an oil-containing granular composition, comprising: an oil-containing granular composition comprising 30 to 75% by weight of an oil-and-fat; and a dry-stirring granulation of dietary fiber and oil-and-fat. I understood. BRIEF DESCRIPTION OF THE FIGURES

 FIG. 1 is a diagram schematically showing a granular state of the oil-containing granular composition of Example 5 observed with a microscope. FIG. 2 is a diagram schematically showing a granular state of the oil-containing granular composition of Example 6 observed with a microscope. BEST MODE FOR CARRYING OUT THE INVENTION

In the present invention, fats and oils 3 0-7 5 weight _^0/0 of the oil-containing granular composition, preferably 4 0-7 5 wt%, good Ri preferably 5 0-7 5 wt. / ₀ is preferred. If the amount is less than 30% by weight, the composition becomes a granular composition having less flavor and richness of fats and oils. If the content exceeds 75% by weight, blocking. Poor resistance occurs, and blocking occurs during distribution and storage.

The oils and fats used in the present invention are not limited as long as they are animal and vegetable oils and fats that can be used in foods, pharmaceuticals, and cosmetics. For example, palm oil, palm kernel oil, coconut oil, castor oil, soybean oil, rapeseed oil, corn Oil, sesame oil, peanut oil, cocoa butter, monkey fat, shea butter, beef tallow, fish oil, etc., and processed fats and oils which have been subjected to separation, hardening, transesterification, etc. And oils and fats obtained by combining these substances. The fats and oils used are preferably 7

Or A〇M test Use a test that is 30 hours or longer. In addition, the fats and oils may contain oil-soluble components that can be used in foods, pharmaceuticals, and cosmetics. Examples of oil-soluble components include, in the case of foods, oil-soluble flavors, emulsifiers and the like, and mixtures of these with oils and fats. In the present invention, the fat and oil represents the total weight% of the fat and oil and the oil-soluble component.

 The fat and oil used in the present invention is preferably a fat and oil having a melting point of 55 ° C or lower. When oils and fats exceeding 55 ° C are used, crystallization after dissolution is rapid and crystallization occurs easily in the mouth, making it difficult to eat and drink.

 The dietary fiber used in the present invention is not limited as long as it can be used for food, medicine, and cosmetics. Examples include dietary fiber using one or more of wheat fiber, soy fiber, corn fiber, and the like.In various studies conducted by the present inventors, wheat stem-derived wheat Fibers are preferred. Dietary fiber should have an oil absorption capacity of 1.5 times or more, preferably 2 times or more, and more preferably 3.5 times or more of its own weight. If the ratio is less than 1.5 times, the oil absorbing ability is low, and the oil and fats seep out to lower the blocking resistance. The average fiber length of the dietary fiber is not particularly limited, but is preferably 10 μm or more, and more preferably 100 μm or more. Examples of dietary fiber products include “Vitacellen WF200”, “Vitacell WF600”, and “Vitacell WF600 / 30” manufactured by Lettmentia Co., Ltd.

In the production method of the present invention, the dietary fiber is easily granulated by dry stirring granulation which does not require the addition of water in the presence of fats and oils. The reason for this is not always clear, but is presumed as follows. In other words, it is considered that when the dietary fiber absorbs fats and oils, the distance between the constituent fibers is reduced because the bulk is reduced, and the fibers are entangled by further stirring, thereby forming granules. .

 As a stirring granulator, a planetary type such as a universal mixing stirrer may be used, but a high-speed stirring type is effective. As a high-speed stirring type, a commercially available product such as “Heavy De Utility 1” manufactured by Nara Machinery Co., Ltd. Type Granulator, Pharmatype Granulator, Vertical Granulator, manufactured by Parek Co., Ltd., New Gram Machine, manufactured by Seishin K.K., High Speed Mixer, manufactured by Fukae Kogyo Co., Ltd. No.

 In the present invention, in order to further improve the heat resistance of the oil-containing granular composition, an oil-absorbing powder having an oil-absorbing capacity of 0.5 times or more of its own weight after granulation is added to 0 part by weight of the oil-containing granular composition. .5 parts by weight or less can be blended and agitation granulation can be performed again. However, when the amount is more than 0.5 part by weight, not only the oil and fat content of the granular composition is reduced, but also the time required for the production becomes longer and the productivity is reduced.

The reason why the above operation improves the bulk specific gravity and the fluidity of the oil-containing granular composition is considered as follows. In other words, it is considered that the oil absorbing powder added after the granulation covers the granule surface, thereby suppressing fluff of the dietary fiber and smoothing the granule surface, thereby increasing the bulk specific gravity and increasing the fluidity. The above oil-absorbing powder can be used for food, pharmaceuticals and cosmetics There are no particular restrictions if they are valid. For example, starches such as dietary fiber, potato, tapiochi, corn, wheat, rice, and the like, or modified starches such as their non-modified starches, and modified starches such as octenyl succinated and phosphorylated, and the like. Hydrolysates thereof. Further, the oil absorbing ability of the oil absorbing powder used is preferably a powder having 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. If the oil absorption capacity is less than 0.5 times the weight of the oil-containing granular composition, the effect of improving the heat resistance of the oil-containing granular composition is reduced, and blocking tends to occur. Examples of oil-absorbing powder commodities include “Vitacell WF 200”, “Vitasenore WF 600”, “Vitasenore WF 600” and “Nitasen Chemical Co., Ltd.” manufactured by Retsutenmeier. Examples include “Oil Q No. 50” and “Oil Q—S”, and “Pinef Kuchiichi” manufactured by Matsutani Chemical Industry Co., Ltd. .

 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 of use. Products that have been classified as necessary shall be used as products. For example, when used in granular instant soup, the average particle size is preferably 0.1 to 3 mm.

The oils and fats used in the oil-containing granular composition of the present invention can be flavored, and the flavoring method is milk fat, lard, beef tallow, fish oil, sesame oil, sesame oil, peanut oil, coconut oil, etc. It may be flavored by appropriately blending fats or oils or oil-soluble flavors having a unique flavor to enhance the flavor. For this purpose, a flavor oil from which insolubles have been removed after heating and mixing the oil and fat used in the present invention with a solid flavor substance such as rice bran, milk powder, leek, sesame, etc. may be used.

 Further, a edible seasoning containing powdered or granular animal or plant extracts, flavors, amino acids, nucleic acids, inosinic acids, organic acids, etc. may be added before or after granulation. Example
