Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to fine particles containing a tea extract and, in some cases, fine particles containing a water-soluble film-forming agent or a polyhydric alcohol, which can be used in the fields of foods and cosmetics. The present invention relates to a deodorant / antioxidant oily or powder composition dispersed therein, as well as foods, cosmetics and deodorants containing these.

2. Description of the Related Art Recently, as the living environment has improved,
There is an increasing demand for reducing or eliminating bad odors and bad breath associated with the body that occur from daily life. Persimmon extract, perilla extract, glucosamine and the like have been proposed as raw materials of deodorants for removing bad smells and bad breath. Further, extracts such as green tea and oolong tea belonging to the Camellia plant and extracts such as bean tea belonging to the Rosaceae plant also have an antioxidant effect and a deodorant effect, and are therefore used in foods and cosmetics. Generally, these extracts are added to foods and cosmetics in the form of an extract powder or in a state of being dissolved in water. As another addition method, Japanese Patent Publication No. 3-49315 proposes a water-in-oil emulsion containing a tea leaf extract. However, since the tea extract in the water-in-oil emulsion is in the form of an aqueous solution, there is a disadvantage that its quality is liable to deteriorate. In addition, when heated to 150 ° C. to 180 ° C., aggregation of the tea extract occurs. Further, when the tea extract is used for foods, its taste is bitter and astringent, so that its application range and usage amount have been limited. Further, the antioxidant action and the deodorant action were not sufficiently satisfactory with a small amount of use. Patent No. 2823706 proposes a tea extract in which cyclodextrin is included.
However, since cyclodextrin entrapment consists of an equilibrium between entrapment and desorption, it is difficult to obtain a 100% complete entrapment of the tea extract, and it is difficult to completely mask the taste. The oily composition or its powder composition in which the tea extract is dispersed in the oil phase in a specific fine particle state and the water content or the alcohol aqueous solution content in the solid phase is a specific amount is a taste of the tea extract. It has not been known so far that the antioxidant effect and the deodorant effect are remarkably enhanced as well as masked.

[0003]

Accordingly, an object of the present invention is to provide foods and cosmetics whose quality is hardly deteriorated by oxidation, foods which reduce or deodorize bad breath, and deodorants which reduce or deodorize bad odors. Is to provide.

[0004]

Means for Solving the Problems In view of the above circumstances, the present inventors have conducted intensive studies and as a result, have found that tea extract is dispersed in an oil phase in a specific fine particle state, and the water content in a solid phase is reduced. Alternatively, it has been found that an oily composition or a powder composition thereof having a specific content of an aqueous alcohol solution can achieve the above object. In the present invention, the solid phase refers to a phase containing a tea extract, having a water content or an aqueous alcohol solution content of 30% by weight or less, and optionally containing a water-soluble film forming agent, a polyhydric alcohol, or the like. It is. The present invention has been made based on the above findings, contains a tea extract,
A solid phase containing a water content or an aqueous alcohol solution content of 30% by weight or less and optionally containing a water-soluble film forming agent or a polyhydric alcohol, and an oil phase containing an oily component and a lipophilic emulsifier. The present invention provides an oily composition or a powder composition thereof for foods and cosmetics. In the powder composition of the present invention, the oil-based composition particles are adsorbed or included on the powder base material, and the solid phase particles containing the tea extract are dispersed in the oil-based composition particles. The antioxidant effect of the tea extract is considered as follows. Caused by the ability of catechin, gallocatechin, epicatechin, epigallocatechin, epicatechin gallate, epigallocatechin gallate and other tannins in tea extract and phenolic hydroxyl groups of flavonoids such as kaempferol, quercetin and myricetin to capture radicals I do. When a water-soluble tea extract is used as a powder or in the form of an aqueous solution in foods and cosmetics, the fats and oils that deteriorate are hydrophobic,
The contact efficiency between the tea extract and the fats and oils is poor, and the effect cannot be fully exhibited. A water-in-oil type emulsion in which an aqueous tea extract solution is emulsified in oil (Japanese Patent Publication No. 3-49315) is also used. In the case of a water-in-oil type, the phenolic hydroxyl groups of catechins are removed to the water side. Since the phenolic hydroxyl group does not easily appear on the surface of the fat or oil, the action site is difficult to function.
Some tea extract powders are directly clathrated with cyclodextrin, but are expected to be less effective because the phenolic hydroxyl groups of catechins are incorporated into the cyclodextrin. In addition, the deodorizing effect of the tea extract is also caused by the binding of phenolic hydroxyl groups of tannins and flavonoids to -NH groups (functional groups such as trimethylamine) and -SH groups (functional groups such as methyl mercaptan) of malodorous substances. It is believed that. Therefore, as in the case of the antioxidant action, the state of the phenolic hydroxyl group affects the strength of the deodorizing action. The tea extract-containing oily or powder composition of the present invention is obtained by dispersing the tea extract in oil in the form of solid phase particles having a particle diameter of 5 μm or less in the oil, and having a water content of 30% or less in the solid phase. In the oily composition and its powder composition, the phenolic hydroxyl groups of the tannins and flavonoids are hydrophilic, and therefore it is expected that the phenolic hydroxyl groups are arranged toward the surface of the oily composition. It is anticipated that fats and oils or powder compositions in which many phenolic hydroxyl groups are arranged on the surface of fats and oils will be able to efficiently capture radicals and -NH groups and -SH groups of malodorous substances, so that antioxidant action and deodorant action are expected to increase. Is done. In this manner, the phenolic hydroxyl group of the tea extract acts efficiently, so that the tea extract powder itself, its aqueous solution, a W / O emulsion containing the tea extract, and cyclodextrin inclusion of the tea extract powder Deodorant action and antioxidant action are more likely to occur than those of products. Furthermore, the reason why the deodorizing action and the antioxidant action are strengthened is that phenolic hydroxyl groups are continuously bonded to radicals, -NH groups and -SH groups on the oil surface, so that the deodorizing action and the antioxidant action are immediately lost. It is expected to work continuously. For these reasons, the quality of foods and cosmetics containing the deodorant / antioxidant composition is hardly deteriorated. Furthermore, when eating a food containing the deodorant / antioxidant composition, bad breath is reduced or eliminated. The deodorant to which the deodorant / antioxidant composition has been added reduces or eliminates odors such as tobacco odor, unusual toilet odor, and shoe odor. Moreover, since the tea extract-containing oily composition of the present invention is composed of an oil phase and a solid phase having a limited amount of water, foaming and aggregation may occur even when added to edible oil heated to 160 to 180 ° C. Does not occur and disperses uniformly in oil. Furthermore, since the taste of the tea extract-containing oily or powder composition is masked, the taste is not impaired even when added to food.
