Description

  The present invention relates to a low odor water-soluble composition, and more particularly, to a water-soluble composition that reduces the odor of water-soluble edible foods containing odorous components such as enzyme-treated hesperidin.

  Conventionally, "Hesperidin" which is a component derived from citrus, "Ruchin" which is a component derived from buckwheat, potato, asparagus, "Stevia" which is a high-sweetness sweetener derived from a Compositae plant originating in South America, or those Enzyme-treated products with improved water solubility have various useful effects and are used in various fields by taking advantage of their properties.

  For example, both hesperidin and enzyme-treated hesperidin exhibit natural pigment fading prevention, blood circulation promotion, and vitamin P-like action. In particular, enzyme-treated hesperidin is used as a glycosylated vitamin P added to foods and drinks, cosmetics and the like ( For example, non-patent documents 1, 2, 3).

  Rutin and enzyme-treated rutin are used as antioxidants, colorants, reinforcing agents, and the like (for example, Non-Patent Document 3). Stevia and enzyme-treated stevia are non-caloric high-sweetness sweeteners. (For example, Non-Patent Document 3).

However, these plant extracts such as hesperidin, rutin and stevia and their enzyme-treated products have their own odors, and their fields of use are limited.
Accordingly, as a result of intensive studies to solve the above problems, the present inventors have made these enzyme-treated products such as hesperidin, rutin, stevia, etc. (preferably, those treated with a porous synthetic adsorption resin). The inventors have found that the addition of a specific component can significantly reduce the odor, leading to the completion of the present invention.

  JP-A-3-7593 (Patent Document 1) discloses α-glycosyl hesperidin in which D-glucose residue is α-bonded to hesperidin in an equimolar amount or more. Disclosed is a method for producing α-glycosyl hesperidin (hesperidin derivative), in which a glycosyltransferase is allowed to act on a solution containing an α-glucosyl sugar compound to generate α-glycosyl hesperidin (reaction mixture), and this is collected. An embodiment in which the obtained reaction mixture is further treated with a synthetic resin adsorbent is also shown. In addition to amylose, dextrin and the like, examples of the α-glucosyl sugar compound include cyclodextrin and the like. In the examples, only an embodiment using dextrin is shown. Patent Document 1 describes that the obtained hesperidin derivative has excellent water solubility, is substantially tasteless and odorless, has no concern about toxicity, and can exhibit physiological activity in vivo.

However, the α-glycosyl hesperidin described in the publication has room for further improvement in terms of odor, particularly when used in combination with lipsticks, depending on the intended use. Even when an α-glucosyl sugar compound such as cyclodextrin is used in the above sugar transfer reaction, cyclodextrin is decomposed during the enzyme reaction, and is also separated and removed by the porous synthetic adsorption resin. It does not exist inside.

  The present invention seeks to solve the problems associated with the prior art as described above, and includes an enzyme-treated product such as hesperidin, rutin, stevia, and the like, and has a significantly reduced odor. It is intended to provide a sex composition.

  The low odor water-soluble composition according to the present invention comprises a water-soluble edible product (a) and an amount of α of 0.01 parts by weight or more with respect to 1 part by weight of the water-soluble edible product (a) (solid content). -Cyclodextrin (b).

  In the present invention, the water-soluble edible product (a) is preferably obtained by allowing cyclodextrin glucanotransferase to act on a plant extract in the presence of a sugar donor.

In the present invention, it is preferable that the plant extract contains one or more of stevia, hesperidin, and rutin as a main component.
In the present invention, the water-soluble edible material (a) is preferably enzyme-treated hesperidin.

In the present invention, the water-soluble edible material (a) is preferably treated with a porous synthetic adsorption resin.
In the present invention, the low-odor water-soluble composition is preferably any of food additives, cosmetic additives, and pharmaceutical additives.

  A food, drink, cosmetic, pharmaceutical product or feed according to the present invention is characterized by including the low odor water-soluble composition described above.

  ADVANTAGE OF THE INVENTION According to this invention, the low odor property water-soluble composition in which the odor of enzyme processed materials, such as hesperidin, rutin, and stevia is reduced significantly is provided. In particular, when α-cyclodextrin is blended with the enzyme-treated product previously treated with a porous synthetic adsorption resin or the like, the resulting low-odor water-soluble composition can be obtained from hesperidin, rutin, stevia, etc. The odor of the plant extract and its enzyme-treated product is further reduced, and it is suitably used for a wide range of uses as described above.

Hereinafter, the low odor water-soluble composition according to the present invention will be described in detail.
[Low odor water-soluble composition]
The low-odor water-soluble composition according to the present invention contains 0-α-cyclodextrin (b) for 1 part by weight of water-soluble edible (a) and the water-soluble edible (a) (solid content). .01 part by weight or more, preferably 0.1 part by weight or more, particularly preferably 0.5 part by weight or more.

  If the content of this α-cyclodextrin is less than the above range, water-soluble edible odors such as vitamin P odor common to hesperidin, enzyme-treated hesperidin, etc. tend to be strongly felt, and the final product The amount added to the product is reduced or cannot be used.

The upper limit of the amount of α-cyclodextrin added is not particularly limited because the type and form of the final product or the effect on the final product is different, but is preferably about 1 million times or less.
In the present invention, a part of this α-cyclodextrin (b) may be substituted with β-cyclodextrin, γ-cyclodextrin, or the like without departing from the object of the present invention. However, considering the effect of reducing the odor, which is the effect of adding α-cyclodextrin, the amount of substitution from α-cyclodextrin to β-, γ-cyclodextrin and the like is desirably as small as possible. For example, β, γ- The total of cyclodextrins is desirably 40% by weight or less, more preferably 20% by weight or less, and particularly preferably 10% by weight or less.

In the present invention, the properties of such a low-odor water-soluble composition are not particularly limited, and can be appropriately determined according to the application used, for example, liquid at normal temperature, jelly, solid, Any of powder etc. may be sufficient.
<Water-soluble edible (a)>
As the water-soluble edible material (a) contained in the low-odor water-soluble composition, a cyclodextrin in the presence of a sugar donor such as starch is added to a plant extract having a specific odor such as stevia, hesperidin or rutin. Α-glycosylated products such as enzyme-treated stevia, enzyme-treated hesperidin and enzyme-treated rutin (α-glycosylated stevia, α-glycosylated hesperidin, α-glycosylated) obtained by the action of glycosyltransferases such as glucanotransferase Also called rutin). Among them, enzyme-treated hesperidin has a strong intrinsic odor, and when α-cyclodextrin is added, a remarkable odor reduction effect is obtained.
