DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a powdered oil and fat composition which does not exude oily components, has good solubility in water, and contains no protein, and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, when an oily component is added to powdered foods or cosmetics, the oily component is directly mixed with salts (Japanese Patent Application Laid-Open Nos. 1-197427 and 3-2093).
No. 11), and impregnated with a saccharide (JP-A-3-5892)
No. 1, JP-A-4-108727). However, in this case, there have been problems in that the surface area increases, the stability of the oily component decreases, and leaching occurs by mechanical force. On the other hand, bath agent compositions which can be easily emulsified and dispersed by using powdered fats and oils (JP-A-6-157286) have been proposed. However, powdered fats and oils generally contain a large amount of protein, and when used in bath agents, the possibility of causing bacterial contamination in bathtubs due to this protein has been regarded as a problem, and has not been put to practical use. In addition, in the case of a person who repels a protein, such as an allergy patient, a material containing the protein must be avoided when put into the mouth as a health food. In addition, gum arabic and carrageenan,
Squalene powders using sodium alginate as an excipient (Japanese Patent Application Laid-Open No. 61-15811) have also been proposed, and attempts have been made to provide powdered fats and oils that do not use proteins. Becomes bad and bad
There was a problem because the insolubles precipitated. For these reasons, a powdered oily component containing no protein that is easily emulsified and dispersed in water has been desired.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a stable powdered oil and fat composition which does not exude oily components, has good solubility in water, and contains no protein, and a method for producing the same. It is.

[0004]

Means for Solving the Problems The present inventors studied various excipients for powdering an oily component, and powdered the oily component using a specific amount of gum arabic and saccharides. We found that we could solve the problem. That is, the present invention comprises an oily component, gum arabic and sugar, the weight ratio of the oily component to gum arabic is 2: 1 to 1: 5, and the weight ratio of gum arabic to sugar is 5: 1 to 1: 1. It is a powdered oil and fat composition characterized by being 100. Further, the powdered fat or oil composition is characterized in that the saccharide used in the above invention is at least one selected from monosaccharides, disaccharides and sugar alcohols which are derivatives thereof. further,

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.
Oil component used in the present invention, for example, rapeseed oil, soybean oil,
Vegetable fats such as palm oil, coconut oil, sunflower oil, safflower oil, macadamia seed oil, camellia seed oil, teaseed oil, olive oil, cottonseed oil, animal fats such as beef tallow, lard, sheep fat, fish oil, and These hardened fats and oils, hydrocarbons such as squalene, squalane, liquid paraffin, sterols such as cholesterol, higher alcohols such as jojoba oil, and oil solubility such as vitamin E, vitamin A, vitamin D, vitamin K, beta-carotene and alpha-carotene. Vitamins, oil-soluble pigments, oil-soluble flavors, sorbitan fatty acid esters, polyglycerin fatty acid esters, monoglycerin fatty acid esters, oil-soluble emulsifiers having a polyoxyethylene chain, complex lipids such as glycolipids and phospholipids, fatty acids, waxes, etc. Yes, these can be used alone or in combination. Fats and oils may be subjected to fats and oils processing such as purification, deodorization, hardening, and transesterification. The oily component usable in the present invention can be used by melting any of liquid, semi-solid, and solid.

The saccharides used in the present invention include, for example, monosaccharides such as glucose, fructose and galactose, disaccharides such as maltose, lactose, sucrose and trehalose, erythritol, sorbitol, mannitol, maltitol, lactitol, palatinit, reduced starch syrup and the like. Sugar alcohols and the like can be preferably used. These can be used alone, or two or more of them can be used.

In the present invention, the mixing ratio of the oily component to the gum arabic is 2: 1 to 1: 5 by weight. If the amount of gum arabic is less than this ratio, the oily component will not be sufficiently emulsified, and the oily component will seep out of the powder, and oil droplets will float when dissolving in hot water, etc. The object of the present invention cannot be achieved, for example, the viscosity of the liquid is increased, which is not only difficult to produce, but also forms lumps when dissolved in water and is difficult to disperse.

In the present invention, the mixing ratio of gum arabic and sugar is 5: 1 to 1: 100 by weight. If the saccharide content is less than this ratio, it becomes lumpy when dissolved in water and becomes difficult to disperse. Less and deviates from the purpose of the present invention.

In the present invention, the method for emulsifying gum arabic, sugar and oily components is to gradually add an oily component to gum arabic and sugars previously dissolved in water, pre-emulsify, homogenize and emulsify. However, any method can be used as long as an oil-in-water type emulsion containing gum arabic and a saccharide in an aqueous phase can be obtained.

In the present invention, the homogenizer used for homogenization may be any homogenizer, high-pressure homogenizer, homomixer, colloid mill, high-speed cutter mixer, etc., as long as it can produce an oil-in-water emulsion. It is possible to use it, and in some cases, it is also possible to make it into powder by pre-emulsification alone.

In the present invention, the method for pulverizing the emulsion is as follows:
For example, a method for drying a liquid such as vacuum drying, vacuum freeze drying, vacuum belt drying, vacuum drum drying, and spray drying is possible, but it is possible to maintain the emulsion stability of the emulsion and the cost required for drying. For example, spray drying is preferable.

In the present invention, in addition to the oily component, gum arabic and sugars, it is also possible to add additives usually used in foods, cosmetics, bath products and the like. In this case, it is important that the ratio of the oily component, gum arabic, and saccharide is the ratio specified in the present invention.
