Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a chewing gum for eliminating bad breath, and more particularly to a chewing gum for eliminating bad breath containing a leaf extract of a plant of the Camellia family.

[Conventional technology]

Deodorants and deodorizers containing extracts of Camellia plant leaves as active ingredients have been very short-lived (for example, Japanese Patent Publication No. 58-18098).
(Japanese Patent Application Laid-Open No. 56-100060, etc.), and the present applicant has also applied for a bad breath removal confectionery in which this kind of extract is blended into a confectionery (Japanese Patent Publication No. 59-66839). The applicant has also discovered that processed leaf extracts of Camelliaaceae plants, such as extracts from black tea and oolong tea, exhibit a different spectrum of halitosis-removing action than green tea extracts, and this patent application was filed in Japanese Patent Application No. 59-6292. No. 1, the disclosure of which is incorporated herein by reference.

In the process of research on bad breath removal, the present inventors discovered that the behavior of substances that have a malodor removal function is extremely specific, and that the conditions under which they are most effective and the types of malodors they target vary. I found out. Furthermore, it was also found that although the pH of saliva in the mouth is on the acidic side when the person is at rest, the pH of stimulated saliva secreted by chewing gum or the like tends from neutral to alkaline. For example, it has been experimentally confirmed that when chewing gum that does not contain acids is chewed, the pl+ in the mouth is semi-permanently maintained on the neutral or alkaline side from the beginning of chewing. These findings. Based on this, we have conducted repeated studies and research into ingredients that can be particularly effective in eliminating bad odors during alkaline conditions during gum chewing, and have found that the combination of non-acidic calcium compounds meets this objective, and stabilizes the alkaline conditions during the day. It was found that it is significantly involved in improving the odor removal function and odor removal function.

[Problem that the invention seeks to solve]

Therefore, an object of the present invention is to provide an enhanced efficacy gum that is particularly effective on the alkaline side and exhibits deodorizing action over a wide spectrum of bad breath.

[Means for solving problems]

According to the present invention, the above-mentioned object is achieved by adding at least 0.005 weight of both a camelliaceae plant leaf extract and a fermentation-treated camelliaceae plant leaf extract as active ingredients to the chewing gum composition it. In addition to containing it in an amount of %,
This is achieved by also coexisting with a non-acidic calcium compound.

The leaves of plants of the Camellia family used in the present invention include camellia, sasanqua,
It includes fresh leaves such as tea and dried leaves thereof, but green tea is particularly preferred. Regarding the extraction, reference can be made to the above-mentioned prior art, and the extraction solvent is water, aliphatic lower alcohol compounds (especially methanol, ethanol, propanol, isopropanol) and polyhydric alcohols (especially glycerin, ethylene glycol, propylene glycol) or Polar solvents such as aliphatic lower ketone compounds (eg acetone, methyl ethyl ketone) and mixtures of two or more thereof can be selected. The deodorizing function of the leaf extract of the Camellia family plant obtained through this method is due to the combined effects of the inclusion, addition, and neutralization reactions of organic compounds such as flavanols and flavonols contained in the extract. This deodorizing effect is remarkable for example against bad odors caused by nitrogen-containing compounds such as pyrazine and nicotine, which make up tobacco odor, or trimethylamine, which makes up rotten fish odor, but this function is pH-dependent. is low.

The other fermented leaves of the Camellia family used in the present invention are not particularly limited, but it is advantageous to use black tea or oolong tea in terms of availability and economy.

Regarding the extraction, Japanese Patent Application Laid-Open No. 60-153 related to the present applicant
Reference can be made to the description in Japanese Patent No. 778, and examples of the extraction solvent include those mentioned above for extraction of leaves of plants of the Camellia family, such as green tea.

The fermented Camellia plant leaf extract obtained through this process is subjected to inclusion and addition of large phenolic compounds such as theaflavin, isotheaflavin, or their gallic acid esters, which are produced through oxidative condensation through the action of enzymes during the fermentation process. It is estimated that it has a deodorizing function by the action of hydrogen sulfide,
It is particularly effective against bad odors caused by sulfur-containing compounds such as methyl, methylcaptan, and dimethyl sulfide.
Its function is strongly pH dependent, and its effectiveness decreases on the acidic side.

From the above point of view, - In order to be effective against both nitrogen-containing compounds and sulfur-containing compounds, which are the three major causes of bad breath when fishing on a boat, it is necessary to use a camellia plant leaf extract and a fermented camellia plant leaf. It is desirable to combine both with medium extract.

However, as described above, the fermented Camellia plant leaf extract has the disadvantage that its efficacy decreases on the acidic side. Therefore, in the present invention, we focused on the fact that the pH of saliva semi-permanently tilts towards alkalinity during mastication during the day, and by stably maintaining this alkalinity, only the deodorizing effect of the leaf extract of the Camellia family plant can be achieved. In addition, in order to exhibit the deodorizing effect of the fermented Camellia plant leaf extract, chewing gum suitable for chewing was selected as the carrier, and by adding a non-acidic calcium compound to this chewing gum, it can be used over a wide range of areas. We have succeeded in obtaining an effective breath odor removal effect against these types of bad odors.

In such a composition of the bad breath removing chewing gum of the present invention, the combined ratio of the extract in the leaves of the Camellia family plant and the fermented leaf extract of the Camellia family plant is in the range of 90:10 to 30:70 by weight. This is preferable in all respects including the deodorizing effect and the taste of the chewing gum itself. In order to use both raw material leaves together, both raw material leaves may be mixed and the mixed leaf may be extracted with the above solvent, or each raw material leaf may be separately extracted with a solvent and then both may be mixed. The total amount of both extractive components used is at least 0.005% by weight, based on the weight of the chewing gum composition.

In order to enhance the deodorizing effect on the alkaline side and stabilize the pH during the day to alkaline, the non-acidic calcium compound mixed into the bad breath removing chewing gum of the present invention may be any non-acidic calcium compound as long as it achieves the above-mentioned effect. In particular, calcium carbonate or tribasic calcium phosphate is preferable from the viewpoint of availability and handling. In order to mix this non-acidic calcium compound component into chewing gum, it can be mixed as a component (filler) of the gum base.
Alternatively or additionally, it may be used as an additive other than the gum base. The amount of non-acidic calcium compound used is 0.1 to 12% by weight based on the weight of the chewing gum composition in order to fully exhibit its function, but it is preferably 0.5 to 5% by weight. can.

In the present invention, as described above, the presence of a non-acidic calcium compound stably maintains the pH in the mouth on the alkaline side during chewing and enhances the deodorizing effect. If it is contained, the pH at the initial stage of mastication becomes acidic, which reduces the deodorizing effect, which is not desirable. In addition to exhibiting the above-mentioned effects, the non-acidic calcium compound itself also exhibits a deodorizing effect on sulfur-containing compounds.

The above three components, namely, the extract in the leaves of the Camellia family plant, the fermented extract in the leaves of the Camellia family plant, and the non-acidic calcium compound can be added to the chewing gum composition by any conventional method based on the above disclosure. Those skilled in the art will appreciate that formulation may vary.

[Effect]

According to the present invention, the presence of a non-acidic calcium compound makes it possible to stably maintain the oral pH in the mouth during mastication on the alkaline side, and thus the fermented leaves of the Camellia family, which have a particularly high deodorizing effect on the alkaline side. The deodorizing effect of medium extracts, such as black tea, can be fully exerted, and by combining this effect with the deodorizing effect of leaf extracts of Camellia plants (for example, Rokucha), it can remove bad breath from an extremely wide spectrum of bad odors. bring about an effect. (Thus, the present invention is extremely useful in the sense of achieving functional enhancement of so-called efficacy gums, and brings about an enrichment of technology in the development of new efficacy gums.
