BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-soluble composition containing higher fatty alcohols which is uniformly solubilized under neutral and acidic conditions and has extremely high solubilization stability, and a method for producing the same. In recent years, higher fatty alcohols, which are components of vegetable waxes, have attracted attention due to their physiologically active effects. They are,
Docosanol (C22H46O), Tetracosanol (
C24H50O), hexacosanol (C26H54O
), octacosanol (C28H58O), triacontanol (C30H62O), dotriacontanol (
C32H66O), tetratriacontanol (C34
H70O) and the like. In particular, octacosanol increases exercise capacity, improves endurance, enhances vitality,
It is known to have excellent physiologically active effects such as alleviating muscle pain. As described above, higher fatty alcohols having 20 or more carbon atoms are increasingly being evaluated highly for their future potential due to their physiologically active effects. Therefore, it would be expected to add higher fatty alcohols to foods, especially beverages.

0002

BACKGROUND OF THE INVENTION Higher fatty alcohols have extremely high melting points (70 to 91° C.) and are difficult to dissolve in most substances, so it has been difficult to use them as uniformly dispersed and stable solutions. For this reason, higher fatty alcohols are only used in solid foods such as candy and ice cream, and are added to foods by sprinkling them as a fine powder or melting and kneading them. Therefore, in order to make it easier to ingest higher fatty alcohols, liquefaction of higher fatty alcohols has become an issue. As a method for liquefying higher fatty alcohols, for example, octacosanol is added alone or in the form of a mixture dissolved in oil or fat to an aqueous solution containing polyglycerol fatty acid ester as an emulsifier, and octacosanol is emulsified using a homomixer. A method for obtaining an emulsified or solubilized octacosanol-containing water-soluble composition (Japanese Unexamined Patent Publication No. 61-263937), in which a higher fatty alcohol is added to water containing a surfactant, heated above the melting point of the higher fatty alcohol, and an emulsifying machine is used. (Japanese Unexamined Patent Publication No. 61-31064) or by dissolving a higher alcohol in a lower alcohol, then precipitating the higher alcohol by mixing with water, and then removing the lower alcohol, and then adding a surfactant. A method for dispersing higher alcohols has been proposed (Japanese Unexamined Patent Publication No. 1983-99334), which is characterized by dispersing the precipitated higher alcohols in water. However, when emulsions produced by these methods are used in beverages, higher fatty alcohols are liberated in the upper part or precipitate during storage, resulting in problems with dispersion stability.

[Problems to be Solved by the Invention] The present invention provides solubilization stability that allows higher fatty alcohols to maintain a uniform solubilized state without precipitation or release even after long-term storage or under acidic conditions. The object of the present invention is to provide a water-soluble composition containing higher fatty alcohols and a method for producing the same.

0004

[Means for Solving the Problems] As a result of intensive research aimed at providing a water-soluble composition containing higher fatty alcohols having extremely good solubilization stability and a method for producing the same, the present inventors have found that a specific interface Using an activator and a lower alcohol, first, a higher fatty alcohol and a surfactant are dissolved and mixed in a lower alcohol, and then the mixture of higher fatty alcohols is emulsified and mixed in water prepared separately. We have surprisingly found that higher fatty alcohols can be solubilized uniformly and extremely stably in water by solubilizing them through a special procedure of removing alcohol, and based on this finding, we have completed the present invention. reached.

That is, the present invention provides a water-soluble composition in which a higher fatty alcohol having 20 to 36 carbon atoms is solubilized in the presence of a surfactant and a lower alcohol, wherein the surfactant has a polymerization degree of 4 to 36. 10 polyglycerin and caprylic acid,
A higher fatty alcohol-containing water-soluble composition which is at least one compound selected from monoesters with lauric acid and oleic acid, particularly a higher fatty alcohol-containing water-soluble composition characterized in that the lower alcohol is ethanol. The composition and the preparation of the composition include dissolving a higher fatty alcohol and a surfactant in a lower alcohol to obtain a solution, and then mixing this solution with water, and then substantially removing the lower alcohol. The present invention provides a method for producing a water-soluble composition containing a higher fatty alcohol, which is characterized in that the higher fatty alcohol is uniformly solubilized in water.

The higher fatty alcohol-containing water-soluble composition of the present invention is mainly used as a raw material for adding higher fatty alcohols to beverages such as sports drinks, carbonated drinks, and nutritional drinks, and so-called functional foods. be able to. The higher fatty alcohol used in the present invention is preferably one extracted, separated, and concentrated from natural plants and animals such as wheat germ oil, beeswax, candelilla wax, carnauba wax, wood wax, montan wax, auricilla wax, rice bran wax, spermaceti wax, etc. It can be used for.

[0007] The purity of the higher fatty alcohol used in the present invention is not particularly limited, and for example, 5 to 100% by weight can be used. Further, these naturally derived higher fatty alcohols usually contain higher fatty alcohols having different numbers of carbon atoms, and these higher fatty alcohols can be used as they are mixed. The amount of higher fatty alcohol blended in the composition of the present invention is 0.
000085-10% by weight, preferably 0.00008
It is appropriate to mix it so that it is 5 to 5% by weight.

[0008] The blending amount of higher fatty alcohol is 0.000
If it is less than 0.085% by weight, no physiological effects can be expected. Furthermore, if the amount of higher fatty alcohol blended exceeds 10% by weight, it becomes difficult to stably solubilize the higher fatty alcohol. In the present invention, the surfactant has a polymerization degree of 4 to 1.
Monoesters of 0 polyglycerol with caprylic acid, lauric acid or oleic acid can be used. As the surfactant used in the present invention, a mixture of two or more types of monoesters consisting of polyglycerin of various degrees of polymerization and various of the above-mentioned organic acids can be used.

[0009] The blending amount of the surfactant in the composition of the present invention is as follows:
A suitable amount is 1 to 300 parts by weight, preferably 1 to 200 parts by weight, per 1 part by weight of the higher fatty alcohol. If the amount is less than 1 part by weight per 1 part by weight of higher fatty alcohol, it will be difficult to stably solubilize the higher fatty alcohol, and if it exceeds 300 parts by weight, the flavor will be poor. As the stabilizer used in the present invention, saponins such as Quillaja saponin, gum arabic, xanthan gum, tragacanth gum, guar gum, locust bean gum, etc. can be used alone or in combination of two or more, but from the viewpoint of the influence on the viscosity of the composition, saponins Particularly preferred are the following.

The blending amount of the stabilizer in the composition of the present invention is 1 to 300 parts by weight per 1 part by weight of higher fatty alcohol.
Preferably, 1 to 200 parts by weight is appropriate. If the amount of the stabilizer is less than 1 part by weight per 1 part by weight of the higher alcohol, it will not be effective in stabilizing the composition, and if it exceeds 300 parts by weight, the flavor will be poor. The lower alcohols used in the present invention are methanol,
Ethanol, propanol, isopropanol, butanol, isobutanol, etc. can be used, but
Ethanol is particularly preferred from the viewpoint of edible safety if it remains in the composition.

[0011] In addition to lower alcohols, solvents that dissolve higher fatty alcohols and are compatible with water can also be used, but none of these are suitable in terms of toxicity. The appropriate amount of lower alcohol in the composition of the present invention is 3 to 10,000 parts by weight, preferably 5 to 5,000 parts by weight, per 1 part by weight of higher fatty alcohol. When the amount of lower alcohol blended is less than 3 parts by weight per 1 part by weight of higher fatty alcohol, it becomes difficult to dissolve the higher fatty alcohol, and when it exceeds 10,000 parts by weight, it becomes difficult to remove the lower alcohol.

In addition to the above-mentioned ingredients, the composition of the present invention also contains granulated sugar, glucose, fructose, sodium chloride, monosodium glutamate, citric acid, sodium citrate, ascorbic acid, citrus juice, orange flavor, grapefruit flavor, etc. Taste substances, flavor substances, etc. can be added as appropriate. The method for producing a higher fatty alcohol-containing water-soluble composition of the present invention can be carried out as follows.

First, a higher fatty alcohol and an oil-soluble emulsifier are dissolved and mixed in a lower alcohol. Separately, add 6 cups of water.
After raising the temperature to 0 to 100°C, preferably 70 to 90°C,
The above mixture of higher fatty alcohols is added and mixed well, and while emulsifying using a propeller stirrer, the lower alcohols are removed by heating under normal pressure or reduced pressure, and the higher fat is made into a homogeneous liquid. An alcohol-containing water-soluble composition is obtained.

Furthermore, this higher fatty alcohol-containing water-soluble composition can be sterilized at 60 to 100°C or, if necessary, subjected to high temperature sterilization at 100 to 150°C. The higher fatty alcohol-containing water-soluble composition thus obtained can maintain a uniform solubilized state without the higher fatty alcohol precipitating or floating even when stored for a long period of time. Moreover, a stable solubilized state can be maintained even under acidic conditions. The higher fatty alcohol-containing water-soluble composition obtained as described above can be ingested as is or used as an additive raw material for drinks or foods. beverages,
When used as an additive raw material for food, 1 to 2000
It is preferable to use it by diluting it to about 0.00 times.

[0015] The beverage thus obtained can maintain a uniform solubilized state without the higher fatty alcohols precipitating or floating even after long-term storage. Beverages containing the higher fatty alcohol-containing water-soluble composition of the present invention can be sterilized at 60 to 100°C or sterilized at 100°C as necessary.
High temperature sterilization treatment at ~150°C can be performed. When making a beverage containing the higher fatty alcohol-containing water-soluble composition of the present invention, for example, minerals such as salt are an essential component, and at least one of acidulants, sweeteners, alcohol, vitamins, flavors, and fruit juice is added. Other examples include sports drinks, milk, soy milk, fruit juice drinks, lactic acid bacteria drinks, carbonated drinks, alcoholic beverages, and nutritional drinks containing vitamins and minerals.
