  However, bamboo water itself and the bamboo extract obtained by the above-mentioned production method have a low content of amino acids and the like, and it is difficult to sufficiently expect the action as a bamboo extract. On the other hand, when the concentration step is performed under atmospheric pressure, amino acids and the like are easily decomposed, degraded, or degraded by heat, and the action as a bamboo extract may be reduced.

  The present invention has been made in view of the above-mentioned conventional circumstances, and has as an object to solve the problem of providing a bamboo extract which can be expected to have a sufficient effect.

The method for producing a bamboo extract of the present invention is a pulverizing step of finely pulverizing a green bamboo stem at room temperature to obtain a pulverized product,
An immersion step of immersing the pulverized material only in water at room temperature for 24 to 48 hours to obtain an extract,
A distillation step of vacuum-distilling the extract at 20 to 60 ° C. to obtain a bamboo extract containing arginine, aspartic acid, threonine, proline, serine, histidine, leucine, lysine, alanine, phenylalanine and glycine in the descending order of amino acids. And characterized in that:

In the production method of the present invention, the pulverizing step is performed at room temperature, and the immersion step is performed by immersing in water at room temperature only for 24 to 48 hours . Then, in the distillation step, the obtained extract is distilled under reduced pressure at 20 to 60 ° C. to obtain a bamboo extract. For this reason, the bamboo extract is unlikely to degrade, alter, or degrade amino acids and the like, and contains amino acids and the like at a higher concentration.

  Therefore, according to the production method of the present invention, it is possible to produce a bamboo extract that can be expected to have a sufficient effect.

  The bamboo extract thus obtained can be used for a lotion for the skin, scalp, etc., as well as a cosmetic cream, soap, lip balm, shampoo, etc. by adding a small amount of an antiseptic such as phenoxyethanol. Phenoxyethanol is a preservative that is safe for the human body.

  Green bamboo is a bamboo whose stem is blue, that is, growing or freshly cut. This is because in bamboo that has passed a long time after felling, amino acids and the like are decomposed, deteriorated or deteriorated. As for bamboo, Madake (bamboo and bamboo), Moso bamboo (Moso bamboo), Hachik (tan bamboo), Medake (memboo), Kurochiku (black bamboo), Hoteichi (Hotei bamboo), Shihoutiku (Yomotake bamboo), Touchiku (karatake), Kumazasa (Kumasa), Chishimasa (Chishima Sasa), Miyakozasa (Miyasa) etc. can be adopted.

  In the pulverizing step, the stem of the green bamboo is finely pulverized at room temperature to obtain a pulverized product. At this time, according to the test results of the inventors, for example, as disclosed in Japanese Patent Application Laid-Open No. 2002-301394 or the like, a fiber planter (registered trademark) capable of crushing pulverized green bamboo to cellulose is used. It is preferable to fiber. This is because more amino acids and the like in cellulose can be extracted. However, in this pulverization step, the temperature and the temperature of the green bamboo stems and the pulverized material are not exceeded, for example, 100 ° C. due to frictional heat. If the bamboo stalks or crushed materials are exposed to high temperatures, amino acids and the like contained in the green bamboo are easily decomposed, deteriorated, or degraded by heat, and the action as a bamboo extract is reduced.

In the immersion step, the pulverized material is immersed in only room temperature water for 24 to 48 hours to obtain an extract. If the immersion time is less than 12 hours, it is difficult to sufficiently extract amino acids and the like from the pulverized material .

In the distillation step, the extract is distilled under reduced pressure at 20 to 60 ° C. to obtain a bamboo extract. At this time, since the bamboo extract is obtained at a pressure lower than the atmospheric pressure, amino acids and the like are not easily decomposed, deteriorated or deteriorated. The conditions of the vacuum distillation can be variously selected according to the use of the bamboo extract to be produced.

Thus obtained bamboo extract, arginine decreasing order as amino acid, aspartic acid, threonine, proline, serine, histidine, leucine, lysine, alanine, including phenylalanine and glycine.

Since the bamboo extract thus obtained is produced by the above-described production method of the present invention, it contains a large amount of the above-mentioned many amino acids and the like. For this reason, this bamboo extract can be expected to work more fully.

ADVANTAGE OF THE INVENTION According to the manufacturing method of this invention, the bamboo extract which can expect an effect | action more fully can be manufactured .

FIG. 1 is a process chart showing a method for producing a bamboo extract of Example 1. FIG. 2 is a process chart showing a method for producing a bamboo extract according to a modification.

  Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

(Example 1)
In Example 1, the manufacturing method shown in FIG. 1 was performed. This manufacturing method includes a logging step S1, a cutting step S2, a crushing step S3, a dipping step S4, and a distillation step S5.

  Moso bamboo grown in bamboo forests for 3 to 4 years is the easiest to grow bamboo shoots every March to April, and contains the most bamboo water between the nodes of the stem. For this reason, in the cutting process S1, the green stem of such a Moso bamboo within 3 m from the ground was cut.

  In the cutting step S2 and the pulverizing step S3, a fiber planting machine (registered trademark) (“SM-18-30CR” manufactured by Shinko Zoki Co., Ltd.) in which a crusher was integrated was used. That is, first, the green stem obtained in the logging step S1 was cut into small pieces of 5 to 10 mm square at normal temperature. And each piece obtained in the cutting step S2 was finely pulverized continuously at room temperature to obtain a pulverized material. In this way, by continuously pulverizing each strip, it is easy to suppress the decomposition of amino acids and the like. However, in the pulverizing step S3, the input amount was adjusted so that each strip or pulverized material did not exceed, for example, 100 ° C. due to frictional heat.

  In the immersion step S4, the crushed material obtained in the crushing step S3 was immersed in water at normal temperature for 24 to 48 hours. The mixture of water and the pulverized product was filtered with a filter to obtain an extract as a filtrate. The residual on the filter can be used for fertilizer and the like.

  Then, in the distillation step S5, the extract was placed in a distillation column and distilled under reduced pressure to obtain a bamboo extract. At this time, distillation was performed by lowering the operating pressure in the distillation column to 100 to 500 mmHg and lowering the boiling point of the extract to 20 to 60 ° C. The steps from the logging step S1 to the distillation step S5 were performed within 2 to 3 days.

  Amino acids in the thus obtained bamboo extract were analyzed by HPLC (High Performance Liquid Chromatography) analysis method. In addition, each strip obtained in the cutting step S2 was immersed in water at room temperature for 24 to 48 hours, and a mixture of water and each strip was filtered with a filter. Amino acids in the obtained extract were similarly analyzed. The results are shown in Table 1 (the unit of the numerical value is ppm).

As shown in Table 1, it can be seen that the bamboo extract of Example 1 hardly decomposes, degrades, or deteriorates amino acids and the like, and contains amino acids and the like at a higher concentration. In the production method of Example 1, the logging step S1, the cutting step S2, and the pulverizing step S3 are performed at room temperature, the immersion step S4 is performed with water at room temperature, and the extract obtained in the distillation step S5 is separated by 20 %. This is because a bamboo extract is obtained by distillation under reduced pressure at ６０60 ° C.

  The bamboo extract thus obtained can be used for a lotion for the skin, scalp, etc., as well as a cosmetic cream, soap, lip balm, shampoo, etc. by adding a small amount of a preservative such as phenoxyethanol.

  The following functional effects of the obtained lotion and the like containing the bamboo extract were organoleptically evaluated by the inventors. (1) As a lotion for the scalp, when it comes into contact with the scalp, the hair on the head becomes hard, the hair becomes elastic and the hair swells. (2) As a lotion for the scalp, when it comes into contact with the scalp, the scalp is moisturized and no dandruff appears. (3) When used on the face as a lotion for the face, the skin is moisturized all day long and glows smoothly. (4) Even when used as a lotion for the skin, the skin has moisture all day long and shines smoothly. (5) If used as a skin lotion on the armpits, feet, etc., the odor disappears in about 5 seconds and is effective throughout the day. (6) Moisturizes the heels (heels) of the feet as a lotion for the feet. (7) When it is blown into the mouth as a bad breath prevention liquid, the bad breath disappears. (8) As a lotion for the hand, apply it to the hand, and touch the back of the hand to the tap water, you will see small tiny bubbles (If the surface of the skin is coated with bamboo extract and covered like a barrier Seem.). (9) When used as a skin lotion on itchy skin of atopic people, itching is removed and the red part is improved. (10) When sprayed on cigarette butts as a deodorant, the nicotine smell disappears.

  Therefore, according to the production method of Example 1, it can be seen that a bamboo extract which can be expected to have a sufficient effect can be produced.

  In the above, the present invention has been described with reference to the first embodiment. However, it is needless to say that the present invention is not limited to the first embodiment, and can be appropriately modified and applied without departing from the spirit thereof. .

  For example, in Example 1 described above, the cutting step S2 and the crushing step S3 were continuously performed by the fiber-planting machine (registered trademark) in which the crushing machine was integrated, but the crushing machine and the fiber-planting machine (registered trademark) The present invention can be practiced even if it is separate. However, even in this case, it is preferable that the crusher and the fiber-planting machine (registered trademark) are continuously placed, and each strip is continuously crushed.

  Further, as shown in FIG. 2, an aging step S6 can be performed between the immersion step S4 and the distillation step S5. In the aging step S6, the extract obtained in the immersion step S4 is aged at room temperature for a certain period to cause lactic acid fermentation in the extract. The bamboo extract thus obtained exerts excellent effects on human skin and deodorization.

  The present invention can be used for lotion and the like.
