BEST MODE FOR CARRYING OUT THE INVENTION Dry leaf flakes of the present invention are produced by squeezing fresh leaves or drying without squeezing and crushing, or crushing and shredding fresh leaves and then drying. The squeezing is performed by a commercially available squeezing machine, and the crushing and drying treatment is preferably performed by cutting with a mixer and drying, but may be crushed after drying. The squeezing is preferably performed in order to accelerate the drying, but the crushing and drying may be performed without the squeezing. The size of the dried leaves of the leaves of the plant of the genus Ganoderma of the present invention depends on whether they are used by spraying, rinsing, liquefying, etc. They range from strips and wires in the length of the front and back to powders. Powdery
As a method of attaching the strip-shaped freshness retaining agent to the paper or box body, a method of mixing the powder or strip-shaped freshness retaining agent into the raw material of the paper or box material, or a method of mixing these powder or strip-shaped freshness retaining agent Method of sealing the layer enclosing the inside of the paper or box material with a breathable film or paper material, or sticking these powder or strip freshness retaining agents to the paper or box surface with an adhesive or adhesive Or a method in which a layered bag enclosing a powdery or strip-like material is attached to the surface of paper or a box. Also, dried or raw leaf strips or leaves of a plant of the genus Hanamyoga of the ginger family are poured into hot water or boiling water (boiling water or a liquid containing other bath components),
The liquid freshness-maintaining agent of the present invention is obtained from hot water / boiled liquid in which the components of the leaves are well eluted by heating. The liquid freshness retaining agent may be impregnated into the paper / box material by spraying on the surface of the paper / box, or the paper / box material may be impregnated with the liquid freshness retaining agent. May be. Alternatively, a freshness preserving agent may be mixed during the production of a paper or box material, and a paper or box may be produced from the material. In these freshness preserving agents, the liquid component (undiluted solution) from the leaves is 10%
When diluted below, the toxicity is mild even when administered orally, but if it is pulverized dry flakes / granules, there is no toxic side effect unless it is in a large amount.
% LD50 = 18000
It is in a state without toxicity at the value of, and there is no problem even if it is taken orally. In non-oral dosage forms, the dosage and concentration can be increased. As the plants belonging to the genus Hanamyoga of the family Zingiberaceae, Tyringae and Ghetto are preferable because they can be cultivated in Japan. Other natural antibacterial substances may be mixed into the freshness preserving agent of the present invention.

Embodiments of the present invention will be described below. The liquid freshness preserving agent used in this embodiment is to dry the leaves of tiling and then pulverize into 10 g pieces into 4 liters of boiling water and boil for about 50 minutes to keep the liquid fresh. Agent. Using this freshness-retaining agent, tests were conducted to maintain the freshness of Satsuma mandarin orange, preserved the freshness of rice, preserved the freshness of banana, and preserved the freshness of potato. The result was as follows. (a): Freshness maintenance test of Satsuma mandarin orange Satsuma mandarin orange is divided into two groups, and the liquid freshness preserving agent of this example is sprayed on the surface of one group of mandarin oranges while the other group is not sprayed. The mold was observed when placed indoors. The results are as shown in Table 1, and the antifungal and freshness retaining power of the present example were well recognized. In the case of Satsuma mandarin which was not sprayed with the liquid freshness preserving agent of the present example, the occurrence of blue mold was observed on the sixth day, but in the case of sprayed, the occurrence of blue mold was not observed even after 12 to 15 days, and the effect was not significant. It was expensive.

[0008]

[Table 1]

(B): Test for maintaining freshness of rice The resulting rice was divided into a plurality of dishes and divided into two groups. One group was sprayed with the freshness-preserving agent of the example from above rice, and the other group was placed in the same indoor environment without spraying the freshness-preserving agent and observed the occurrence of mold on the rice. The results are as shown in Table 2 below. In the non-sprayed group, the occurrence of black mold was observed on the fifth day. However, in the case of the group sprayed, no black mold occurred on the fifth day, and the occurrence of mold was recognized for a long time. However, it was recognized that the antifungal freshness retaining power was high.

[0010]

[Table 2]

(C): Freshness retention test of banana A plurality of bananas from the same bunch are divided into two groups, and the freshness retention agent of the embodiment is sprayed on the surface in one group, and the other group is not sprayed. As it was left indoors, the change was examined. As a result, in the bananas in the sprayed group, only a few black spots (black discoloration) occurred on the 8th day, but in the non-sprayed group, the entire skin surface turned black as a whole. The effect of keeping freshness was recognized. (d): Test for maintaining freshness of potato The freshness-preserving agent of the example was sprayed on a potato having a slight mold, and left in a room. As a result, it was confirmed that even on the fifteenth day, with little progress of the mold, the increase of the mold was well suppressed and the freshness was maintained. (e): Test of freshness-retaining paper Mold was found even when grape and loquat were wrapped with paper wrapping paper impregnated with the freshness-preserving agent of the present invention and left indoors. It was kept fresh for a long time. If you wrap cabbage with the same freshness wrapping paper,
No decay was observed until the day and the freshness was well preserved. Although the freshness preservative of the example used leaves of Dairingetsuto,
The fresh leaves of ghetto are dried and pulverized, and the leaf dried pieces dried in a microwave are poured into boiling water of decalcified tap water, boiled for 30 minutes or more, and the liquid eluted with leaf components is freshened. A freshness retention test was performed using the retaining agent, and the same good freshness retention power as above was observed.

[0012]

As described above, according to the present invention, a freshness preserving agent is sprayed, sprayed, or adhered to food, or a freshness preserving paper, a freshness preserving bag impregnated with and adhering to a freshness preserving agent,
If a freshness holding box and a freshness holding internal fixing material are used, the generation of spoilage and mold of food can be suppressed, and freshness can be maintained for a long time.
