Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention includes allyl isothiocyanate extracted from horseradish, etc.
The present invention relates to an allyl isothiocyanate inclusion agent used for antibacterial activity, deodorization, freshness retention, etc. when placed inside a shoe box or the like.

[0002]

2. Description of the Related Art Allyl isothiocyanate extracted from wasabi, pepper or garlic has been known to have antibacterial, deodorant and freshness-retaining effects. Therefore, conventionally, this allyl isothiocyanate is contained in foods such as candy, ice cream and bakery, and is mainly used for preventing food crunch. However, allyl isothiocyanate has various effects such as antibacterial and deodorant in addition to the prevention of lumpiness as described above, so that it can be said that allyl isothiocyanate is effectively used only by including it in food. Absent. Therefore, if this allyl isothiocyanate inclusion agent containing allyl isothiocyanate is packed in a container and placed in, for example, a refrigerator or a closet, it is possible to perform antibacterial or deodorant in the refrigerator or closet. The freshness of the food inside can be maintained, which is convenient. However, even if allyl isothiocyanate is simply included to prepare an allyl isothiocyanate inclusion agent, it is difficult to diffuse allyl isothiocyanate from the inclusion agent, and it is possible to effectively exhibit the effects such as antibacterial activity, deodorization, and freshness retention. There is a problem that it does not exist.

[0003]

DISCLOSURE OF THE INVENTION The present invention has been proposed in view of the above circumstances, and its object is to easily release allyl isothiocyanate and to widely use it for antibacterial, deodorant, freshness preservation, etc. It is to provide an allyl isothiocyanate-containing agent to be obtained.

[0004]

The present invention solves the above problems by providing an allyl isothiocyanate inclusion agent having the following characteristics. The allyl isothiocyanate-containing agent of the present invention comprises a gel-like substance having a gel-like form, which contains allyl isothiocyanate extracted from horseradish and the like and a volatile agent for volatilizing the allyl isothiocyanate. is there.

Allyl isothiocyanate is extracted from horseradish, pepper, or garlic, and can be composed of one or more selected from these.
Of these, the one extracted from wasabi is the most antibacterial, deodorant,
It has a strong effect of maintaining freshness and is preferable in this respect. The blending ratio is preferably about 0.01 to 1.0% by weight with respect to the total weight, and if it is 0.01% by weight or less, it is difficult to exert the effects of the wasabi extract such as antibacterial properties, deodorization and freshness retention. on the other hand,
It is possible to add 1.0% by weight or more, and there is no problem even if it is added.
Only the same effect as in the case of blending is obtained, and as a result, it is economically preferable to keep it at about 1.0% or less.

The volatile agent is for facilitating the emission of allyl isothiocyanate. When the volatile agent volatilizes, allyl isothiocyanate is simultaneously emitted, and thereby allyl isothiocyanate is effectively emitted. be able to. The volatile agent may be water-soluble and volatile, and examples thereof include alcohols such as ethanol, isopropyl alcohol, and methanol. Of these alcohols, ethanol is not toxic and is suitable for antibacterial, deodorant and freshness maintenance of foods, and is preferable in this respect. The mixing ratio of this volatile agent is preferably about 5 to 15% by weight with respect to the total weight, and when it is 5% or less,
The effect as a volatile agent is diminished. On the other hand, 15
It is also possible to mix in an amount of more than 10% by weight, and there is no problem even if it is added, but in many cases it is difficult to dissolve in a gel-like substance even if more than 15% by weight is added, and even if it is added, it volatilizes immediately. As a result, only the same effect as in the case of blending about 15% by weight can be obtained. Therefore, it is economically preferable to keep the blending ratio to about 15% or less.

The gel-like material is for efficiently releasing allyl isothiocyanate. For example, when the allyl isothiocyanate inclusion agent is composed of a liquid,
The volatile agent evaporates and disappears within a short period of time, but by making it usable in a gel state, allyl isothiocyanate can be gradually emitted together with the volatile agent. The allyl isothiocyanate-containing agent of the present invention exhibits a gel state by this gel-like substance, and if it is placed in a refrigerator, for example, it keeps the antibacterial and deodorant in the refrigerator for a long time, or keeps the freshness of food in the refrigerator. It is said that it is suitable for being placed and used.

The gel-like substance may be any gel-like substance which can contain a volatile agent, and can be obtained, for example, with water and a gelling agent. In this case, the gelling agent is Examples of gelling agents that have been widely used conventionally for gelation include carrageenan, potassium chloride, benzoic acid, and surfactants, but the present invention is not limited to this, and other components may be used.

[0009]

EXAMPLES The allyl isothiocyanate-containing agent of the present invention will be described in more detail below.

Warm 1000 cc of water to above 80 ° C,
20g of carrageenan as a gelling agent and 5 parts of potassium chloride
g, benzoic acid 5 g, and a surfactant 5 g to prepare a gel-like material. On the other hand, an allyl isothiocyanate extract (hereinafter referred to as wasabi extract) extracted from wasabi is mixed with ethanol as a volatile agent and dissolved to prepare an ethanol solution containing wasabi extract. Then, after cooling the gel-like material to about 40 ° C. or less, an ethanol solution was blended with the gel-like material and stirred to obtain an allyl isothiocyanate-containing agent having a blending ratio as shown in Table 1 below. . In addition, 4
The reason why the ethanol solution was blended after cooling to about 0 ° C. or less is to prevent the blended ethanol solution from volatilizing easily if it is blended at high temperature. When the gel-like material is produced at room temperature, the ethanol solution can be immediately added without cooling.

[0011]

[Table 1]

The thus obtained allyl isothiocyanate-containing agent was subjected to a freshness retention test, an antibacterial test, and a deodorant test. The test results are shown in Tables 2 to 4 below.

[0013]

[Table 2]

Table 2 shows the test results of the freshness retention test.
In this freshness retention test, 60 to 70 g of raw ramen was placed in a polyethylene bag and hermetically sealed (Sample Nos. 1 to 3)
And 60 to 70 g of raw ramen and horseradish powder placed in a polyethylene bag and sealed (Sample Nos. 4 to 5), 60 to 70 g of raw ramen and the allyl isothiocyanate inclusion agent of the present invention product in a polyethylene bag. Samples that were put in and sealed (Sample Nos. 6 to 9) were prepared, and each sample was examined after 7 days, 14 days, 21 days, and 1 month after the occurrence of mold.

The results of the freshness retention test are shown in Table 2 below. When only 1 to 3 of raw ramen was added, a large number of molds were generated after 21 days, whereas when the allyl isothiocyanate-containing agent of the present invention was added together, molds were not formed even after 1 month. No outbreak was observed. In addition, sample No. The addition of 4 to 5 wasabi powder suppressed the generation of mold, but the effect was smaller than that of the product of the present invention containing the allyl isothiocyanate inclusion agent together. It is considered that this is because allyl isothiocyanate was effectively diffused into the atmosphere by ethanol in the present invention.

[0016]

[Table 3]

Table 3 shows the test results of the antibacterial test. This antibacterial test was to test the increase and decrease in the number of Staphylococcus aureus, Escherichia coli, putrefactive bacteria, and Vibrio parahaemolyticus. The condition is that filter paper impregnated with each of these test bacterial solutions and liquid medium is tested. , Put on a petro dish. And, this petro dish set in a cylindrical sealed container (Sample No. 1),
The petro dish was set in a cylindrical hermetically sealed container, and a sample of the allyl isothiocyanate-containing agent of the present invention placed under the petro dish (Sample No. 2) was prepared.
Each cylindrical sealed container was cultivated in a 30 ° C. egg incubator for 48 hours and 72 hours, and each time sample was taken out, diluted and then pour cultivated to calculate the number of general viable bacteria.

As shown in Table 3, the results of the antibacterial test showed that Staphylococcus aureus, Escherichia coli, putrefactive bacteria and Vibrio parahaemolyticus were present in a considerable number at the beginning, but after 48 hours by the allyl isothiocyanate inclusion agent of the present invention, It became 10 or less.

[0019]

[Table 4]

Table 4 shows the test results of the deodorant test. This deodorization test was performed by examining the reduction rate of ammonia, which is a source of odor, after 15 minutes and 30 minutes, respectively, and also by smelling the odor after 30 minutes to examine the presence or absence of odor.

As shown in Table 4, the results of the deodorant test are 3
After 0 minutes, ammonia almost disappeared, and almost no odor was felt. Since almost no odor was sensed after 30 minutes, mercaptan, hydrogen sulfide, etc., which are sources of odors other than ammonia, are considered to have the same effect as ammonia.

The allyl isothiocyanate-containing agent of the present invention is used as a figurine packed in a container such as a refrigerator, a drawer, and
Not limited to the aspect of being placed inside a shoe box or the like, for example, a gel-like substance consisting of a water-absorbing polymer, to constitute the allyl isothiocyanate inclusion agent of the present invention by impregnating allyl isothiocyanate and ethanol, This may be arranged on a diaper or the like. By doing this, allyl isothiocyanate can be efficiently released from the water-absorbing polymer by the volatilization of ethanol,
Antibacterial and deodorant such as diapers can be performed.
