Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a deodorant containing a natural plant extract as an active ingredient. The present invention relates to a deodorizing agent that is highly effective against malodor substances, particularly those whose malodor sources are nitrogen compounds such as trimethylamine and yellowish compounds such as methyl mercaptan.

[Prior art] Conventional deodorization methods include masking with aromatic substances, chemical deodorization with oxidizing agents, neutralizing agents, fixatives, etc., or adsorption with activated carbon, etc. to remove bad odors. However, these methods are often subject to significant limitations depending on the intended use.

Particularly in the food field, deodorants containing cyclodextrin, chlorophylls, and some plant extracts as active ingredients have been reported.
Although patent applications have been filed, many of them have a narrow practical scope in terms of color, taste, aroma, etc., and their effectiveness is not sufficient, especially for sulfur compounds such as hydrogen sulfide and methyl mercaptan. There is a desire to develop a more effective deodorant.

[Problems to be Solved by the Invention] The present invention is a deodorizer containing a highly safe natural plant extract as an active ingredient that can be used with confidence in food products, and which is a deodorant that contains various malodorous substances, especially trimethylamine. The purpose of the present invention is to provide a deodorizing agent that is highly effective against those whose odor sources are nitrogen compounds such as sulfur compounds such as methyl mercaptan, and sulfur compounds such as methyl mercaptan.

[Means for Solving the Problems] According to the present invention, there is provided a deodorant characterized by containing an extract of a plant belonging to the genus Rubus of the family Rosaceae as an active ingredient.

Further, according to the present invention, there is provided a deodorant characterized by containing as an active ingredient an extract obtained by subjecting a plant of the genus Rubus of the Rosaceae family to an essential oil removal process and a deodorizing active ingredient extraction process. Odorant is provided.

When extracting the deodorant described above, it is preferable to use water, alcohols such as methanol and ethanol, ketones such as acetone and methyl ethyl ketone, or a mixture thereof as the active ingredient extraction solvent.

The product of the present invention is a deodorant containing an extract of a plant of the genus Rubus of the Rosaceae family as an active ingredient. Examples of plants of the genus Rubus belonging to the Rosaceae family include whole plants such as raspberries, blackberries, dew berries, and more preferably the above-ground parts. The raw materials of the present invention, such as raspberries and blackberries, have been consumed as herbal teas in Europe for a long time, and there is no problem with their safety.

In the present invention, it is possible to perform essential oil removal treatment, and methods include steam distillation or extraction with a low polar solvent such as hexane.
As a method for extracting the active ingredient, a method that extracts a highly polar substance at a high concentration is preferred, and as an extraction solvent, water, alcohols, ketones, or a mixture thereof is optimal.

For the extract obtained by extraction, usually
Perform concentration. Suitable concentration methods include freeze drying and vacuum concentration using an evaporator, but are not particularly limited thereto.

The present invention has various uses, but since it can deal with a wide range of bad odors such as nitrogen-based and sulfur-based bad odors, it can effectively deal with everything from bad odors in factories to household odors, and even bad odors in toilets, and is also safe. Since it is also expensive, it is possible to incorporate it into chewing gum, candy, toothpaste, etc., and such use is considered to be effective.

The amount added of the product of the present invention is 0.0001 to 10% by weight.
is preferable, and more preferably about 0.01 to 1% by weight.

[Function] Regarding deodorants in the food field, deodorants containing cyclodextrins, chlorophylls, and some plant extracts as active ingredients have been reported and patent applications have been filed, but their development is not yet sufficient. I couldn't say it. Therefore, as a result of conducting a series of studies on deodorants that have a high deodorizing effect and are safe to use on the human body, we discovered that an extract from a plant of the genus Rubus in the Rosaceae family has an effective deodorizing effect. The present invention has now been completed.

Regarding plants of the family Rosaceae, plants of the genus Prunus of the family Rosaceae,
Deodorants containing extracts of plants of the genus Rubus as active ingredients have been reported and patent applications have been filed, but such effects are not known for extracts of plants of the genus Rubus in the Rosaceae family, and the present invention has been proposed. It was revealed for the first time.

For example, JP-A-60-126162 describes a method for producing a deodorant made from an extract of a plant of the genus Prunus of the family Rosaceae, Journal of the Japanese Society of Agricultural Chemistry Vol. 58, No. 6, Nos. 585-589.
Mitsugu (1984) describes the ``deodorizing effect of plant extracts on methyl mercaptan,'' and especially the first part.
On page 587, the deodorization rates of various Rosaceae plant extracts are described, but the Rosaceae Rubus plant extract disclosed by the present invention is not described. Furthermore, the deodorization rate of the Rosaceae plant extract described in this document is 1 to 77%, but the deodorization rate of the Rosaceae plant extract disclosed in the present invention is approximately 1 to 77%, as described later.
It can achieve up to 100% deodorization, and has a very high deodorization rate compared to conventional deodorants.

The product of the present invention has a high deodorizing effect on both nitrogen-based malodors such as trimethylamine, which are said to be the two major malodorous substances, and sulfur-based malodors such as methyl mercaptan, and has a low taste, making it easy to use. It is also highly safe. In addition, since the active ingredient is not derived from an essential oil fraction, it is possible to perform essential oil removal treatment, and unlike conventional masking deodorants, the deodorant itself does not cause discomfort due to its own odor.

[Effects of the Invention] According to the present invention, there is provided a deodorizer containing as an active ingredient a highly safe natural plant extract that can be used with confidence in food products, and which is effective against various malodorous substances,
In particular, a deodorizing agent is provided that is highly effective against those whose odor sources are nitrogen compounds such as trimethylamine and sulfur compounds such as methyl mercaptan.

[Examples] Hereinafter, the present invention will be explained in more detail with reference to Examples, but the present invention is not limited only to the following Examples.

First, an example of extracting the plant extract of the present invention from a plant belonging to the genus Rubus of the family Rosaceae will be shown. Next, a test example will be shown to confirm the deodorizing effect of the present invention, and furthermore, the product of the present invention will be used in several applications. An example of usage is shown.

Extraction example A specific example of the extraction method is shown below.

ml for 10 hours three times to remove the essential oil. Add 200 ml of 50% ethanol to the raspberry powder that has been treated to remove essential oils, attach a reflux condenser, and extract while refluxing at 80°C for 3 hours. Approximately 3 g of the product of the present invention can be obtained by filtering the obtained extract, removing the solvent, and then drying it in a connected manner.

Test Example The deodorizing effect of the product of the present invention was measured using gas chromatography. The test method and results are shown below.
