Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agent for preserving freshness of a living corpse, and more particularly, to an agent for preserving freshness of a living corpse, which suppresses decay and odor generation of human remains.

[0002]

2. Description of the Related Art The corpses of living organisms, especially human bodies,
It may be kept indoors for several days or more depending on circumstances until the cremation or burial is processed. However, if the dead body is stored indoors for a long time, especially in summer, the decay-promoting bacteria work actively due to the cessation of cell activity, so that the dead body rapidly decays, causing a strong putrid odor. Furthermore, various protein odor components and the like are volatilized as bad odors along with the water evaporation generated by the remains. As a result, sanitary pests such as flies would fly around the body, giving a great discomfort to the surrounding people.

[0003] However, due to human consciousness and feelings about relatives such as relatives, it is not easy to spray commercially available insecticide sprays directly or indirectly on the corpse. At present, no effective countermeasures have been taken.

[0004] On the other hand, as a means for preventing the corpse, which is a fundamental cause of the flying of such sanitary pests and the generation of odor, and maintaining its freshness, dry ice has been conventionally placed around the corpse. A method of suppressing the decay of the corpse by keeping the corpse in a low temperature state while partially maintaining the corpse, and a method of suppressing the decay by bacteria by spraying an alcohol-based disinfectant are known.

[0005] However, neither dry ice nor alcohol-based disinfectants have been able to obtain a sufficient body freshness preserving effect, especially at high temperatures in summer.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art and to provide a freshness preserving agent which can maintain the freshness of living corpses such as human corpses, especially for a long time even in summer. To provide.

EXAMPLES Example 1 Raw scallops were used as test specimens.

First, a test specimen having a viable cell count of 10 or less by applying disinfecting ethanol was allowed to stand still in a petri dish in a general environment room at 25 to 30 ° C. Next, the freshness retaining agent having the composition shown in Table 1 filled in a non-gas injection container was sprayed twice a day (at 8 o'clock and 20 o'clock) on the test specimen in a mist form. The test specimen was observed once daily for 10 days at predetermined times for changes in the number of bacteria, odor and appearance on the surface of the test specimen. The results are shown in Table 2.

The number of bacteria, odor and change in appearance on the surface of the test specimen were measured by the following methods.

Changes in the number of bacteria present on the surface of the specimen The bacteria were collected by rubbing the surface of the specimen with a sterilized needle for collecting bacteria, and the bacteria were collected on an agar medium (medium: 1/500 culture solution, meat extract: 10 mg / L + peptone: 20 mg +
Sodium chloride: 10 mg / L)
After standing for 4 hours, the number of viable bacteria in the medium was measured.

Odor change Using a portable type odor sensor "XP-329" (a measuring device for hydrogen sulfide manufactured by Shin-Cosmos Electric Co., Ltd.), the odor level generated from the test specimen was measured.

Changes in Appearance The specimen was visually observed from above, and evaluated based on the following five criteria. 1: No change (with gloss) 2:
Water separation (drip generation) 3: Water separation / discoloration (no gloss),
4: Water separation / throat generation, 5: Shape deformation

Examples 2 to 6, Comparative Example 1 Changes in the number of bacteria, odor and appearance on the surface of the test piece were carried out in the same manner as in Example 1 except that the composition of the freshness preserving agent was as shown in Table 1. Was observed. However, the odor level is 100
When the value exceeded 0 and the appearance became “5”, the observation was terminated there. The results are shown in Tables 2 to 4.

Comparative Example 2 A freshness-retaining agent was present on the surface of a test body in the same manner as in Example 1 except that a commercially available alcohol-based disinfecting spray (containing about 50% ethanol) was sprayed instead of spraying. Changes in bacterial count, odor and appearance were observed. However, on the 5th day after the start of the observation, the odor level exceeded 1000, and the appearance became “5”, so the observation was terminated there. Table 4 shows the results.

Comparative Example 3 Example 1 was repeated except that the freshness preserving agent was not sprayed on the test specimen.
In the same manner as in, changes in the number of bacteria, odor and appearance on the surface of the test specimen were observed. However, on the fourth day after the start of the observation, the odor level exceeded 1000, and the appearance became "5", so the observation was terminated. Table 4 shows the results.

Comparative Example 4 The number of bacteria existing on the surface of the test piece was determined in the same manner as in Example 1 except that the freshness preserving agent was not sprayed on the test piece, and instead dry ice was allowed to coexist in the petri dish. Changes in odor and appearance were observed. However, on the 5th day after the start of the observation, the odor level exceeded 1000, and the appearance became “5”, so the observation was terminated there. Table 5 shows the results.

Example 7 A human body (middle-aged male) was used as a test body.

The same freshness preserving agent as used in Example 1 was sprayed twice a day (morning and evening) onto a test body which was allowed to stand still in a room having an outside air temperature of 25 to 29 ° C. in the form of a mist. Once per day for five days at a predetermined time, the test specimen was observed for changes in the number of bacteria and the odor existing in the most part of the test specimen. Table 6 shows the results. In addition, the number of bacteria existing in the most part of the test body was measured by the following method. Also,
The change in odor was measured using the same device as described above.

Changes in the number of bacteria present on the cheeks of the test sample The bacteria in the relevant portion were collected by bringing the film into close contact with the cheeks of the test sample, and this was transferred to an agar medium (medium: 1/5).
00 culture solution, meat extract: 10 mg / L + peptone: 20
mg + sodium chloride: 10 mg / L)
After standing at 24 ° C. for 24 hours, the number of viable bacteria was measured.

Comparative Example 5 Example 7 except that the freshness preserving agent was not sprayed on the test specimen.
In the same manner as in the above, changes in the number of bacteria and the odor existing in the most part of the test specimen were observed. Table 6 shows the results.

According to the above results, the tea tree oil and the humus solution of the present invention are very effective in maintaining the freshness of a living corpse, as compared with the conventional method using dry ice or an alcohol-based disinfectant. It can be seen that the addition of a preservative or an alcohol-based preservative has a more remarkable effect.
