Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil-soluble substance solubilizing composition obtained by transparently solubilizing an oil-soluble substance in water, a process for producing the composition, and a food or drink containing the oil-soluble substance solubilizing composition.

[0002]

2. Description of the Related Art Conventionally, in the case of foods and drinks, especially beverages, when an oil-soluble substance is added to a beverage, various additives are blended and subjected to a heat sterilization treatment, so that it is excellent in acid resistance, salt resistance and heat resistance. Is required. Furthermore, it is desired to maintain a uniform emulsified or solubilized state without causing creaming or separation of an oil-soluble substance even after long-term storage. Here, creaming means that emulsified fats and oils are partially separated and a part or all of the cream is creamy. Also, when blending an oil-soluble substance in a food or drink where high transparency such as a beverage or jelly is desired, since the oil-soluble substance is emulsified,
It usually becomes cloudy and its appearance deteriorates. Therefore, the amount of the oil-soluble substance added to such a substance is necessarily limited.

[0003] In order to develop foods and drinks containing a large amount of oil-soluble substances, various techniques have been conventionally studied. For example,
A method for solubilizing fats and oils in an aqueous phase containing proteins and sugars (Japanese Patent Application Laid-Open No. 56-144053), and a method for solubilizing oil-soluble substances in water using polyglycerin unsaturated fatty acid esters and sugars or sugar alcohols (Tokuhei 6-3686
No. 2) is known. However, the former has low acid resistance and salt resistance, and cannot maintain a stable solubilized state in the presence of an acidic or concentrated salt, and the latter uses a small amount of saccharides or sugar alcohols. Poor stability in solubilized state. Both of them were excellent in acid resistance, salt resistance and heat resistance, and could not be sufficiently satisfied as a composition for maintaining a stable solubilized state.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to maintain a homogeneous solubilized state without causing creaming or separation of an oil-soluble substance even when stored for a long period of time.
Another object of the present invention is to provide an oil-soluble substance solubilizing composition having excellent acid resistance, salt resistance, and heat resistance.

[0005]

Means for Solving the Problems The present inventors have made intensive studies to solve the above problems, and as a result, if a specific polyglycerin fatty acid monoester is used to solubilize an oil-soluble substance,
A stable oil-soluble substance solubilizing composition having excellent acid resistance, salt resistance, and heat resistance can be obtained, and the food or beverage containing the composition can be creamed or separated from the oil-soluble substance even after long-term storage. Without finding the fact that a uniform solubilized state can be maintained without this, the present invention was completed based on this finding.

That is, the present invention relates to a polyglycerol fatty acid monoester composed of a monoester of polyglycerin having an average degree of polymerization of 5 or more and myristic acid or oleic acid, from 0.01 to 30% by weight, and from 40 to 80% by weight of a polyhydric alcohol. % And an oil-soluble substance in an amount of from 0.01 to 20% by weight, with the balance being water. The above composition is subjected to a homogenization treatment at a pressure of 1000 kg / cm ² or more. And a food or beverage containing the oil-soluble substance solubilizing composition.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The oil-soluble substance solubilizing composition of the present invention is a composition containing water, a polyglycerol fatty acid monoester, a polyhydric alcohol and an oil-soluble substance. It is stably dispersed in water and transparently solubilized. The solubilization in the present invention means that the system is uniform and has transparency, and the transmittance to water at a wavelength of 660 nm is 90% as measured by a spectrophotometer.
The above is referred to.

[0008] The oil-soluble substance used in the present invention may be any substance having no affinity for the aqueous phase but having an affinity for the oil phase, and specifically includes, for example, a coloring agent, a flavoring agent, a nutrient enhancer, and an antioxidant. , Preservatives, disinfectants, oil-soluble substances such as fats and oils.

It is a monoester. When the average degree of polymerization of polyglycerin is less than 5, a transparent oil-soluble substance solubilizing composition cannot be obtained. Fatty acids constituting polyglycerin fatty acid monoesters other than the above fatty acids make it difficult to obtain a transparent oil-soluble substance solubilizing composition. Monoesters of polyglycerol with an average degree of polymerization of 10 and oleic acid are particularly preferred. Myristic acid is more acid resistant than oleic acid,

More preferably, it is 50 to 70% by weight. When the blending amount of the polyhydric alcohol is less than 40% by weight, it is difficult to obtain a stable oil-soluble substance solubilizing composition, and when it exceeds 80% by weight, the viscosity increases and it is difficult to solubilize the composition.
