2. Description of the Related Art In recent years, the demand for cut flowers has grown along with the expansion of the flower market, and interest in freshness preservation technology has also increased. The harvested cut flowers cannot receive nutrients from the roots and leaves, so by consuming nutrients such as sugar as a respiratory substrate, they have a living effect (breathing).
Is running. However, with this respiratory action, respiratory fever is generated, which raises the temperature of the cut flowers and further promotes respiratory action and other physiological reactions. Especially for cut flowers that are shipped at high temperature, the quality of the cut flowers is rapidly deteriorated due to an increase in the product temperature, causing "smearing" and the yellowing of the leaves. Also, in cut flowers, “wiring” occurs due to physiological water release during breathing and physical dissipation of water from the epidermis. This "wielding" can be recovered to some extent by landing, but if the "wiring" becomes severe, water absorption is poor and the commercialability is deteriorated. Furthermore, when the components contained by the respiratory action are exhausted or the water content decreases due to the transpiration action, the resistance to microorganisms is lost, so when the cut flowers are physically damaged, such as by breaking, It will also corrupt. In addition, many cut flowers such as carnations generate a large amount of ethylene when "wiring",
It is also known that this ethylene further promotes flower wilting, flower drop and bud bud. Due to the nature of such cut flowers, how to control respiration, transpiration, microbial contamination, and ethylene generation after harvesting is an important issue in maintaining the freshness of cut flowers. Has become.

[0004] In order to suppress the transpiration action, there is adopted a method in which cut flowers are packaged so as to keep a humidity above a certain level, or recently, a high humidity environment of 90% RH and a low temperature environment. A method of suppressing both respiration and transpiration is adopted by combining and, and the device is being implemented. To prevent microbial contamination and suppress ethylene generation, cut flowers are treated with STS (Silver Thio Sulphate)
Various treatment techniques such as chemical treatment for treatment with an ethylene production inhibitor, adsorption of ethylene by a substance having an ethylene adsorption function such as green pseudo-olites, and decomposition of ethylene by ozone have been partially put into practical use. Conventionally, the freshness of cut flowers is maintained by combining the above methods of low temperature storage, high humidity storage, chemical treatment, ethylene removal, etc., alone or in combination.

According to the first aspect of the invention, the cut flowers are housed in a container capable of being sealed, and a non-polar gas having low activity and easily dissolved in water is injected into the container so that the partial pressure becomes a predetermined pressure. Close the container and keep the container at a temperature lower than room temperature, for example 10 ° C.
Since the temperature is maintained at a temperature of a certain degree or lower, the metabolism of cut flowers is suppressed and the progress of so-called aging is stopped within this holding period, while the biological function is maintained. This holding period may be long, so that the cut flowers can be stored for a long period of time and then returned to their natural state.

As the non-polar gas having a low activity and being easily dissolved in water, for example, xenon gas or krypton gas, which has a relatively high solubility in water among inert gases, as well as cyclopropane, which has a high solubility in water and is active. Of low gas can be used. Such a non-polar gas is a colorless, odorless and non-toxic gas, and does not cause any environmental problem even if it is released into the atmosphere.

The fact that metabolism is suppressed by the method of the present invention will be further described as follows. When the nonpolar gas dissolves in water, which is the main component of cut flower cells, the number of hydrogen-bonded water molecule populations increases. That is, the water molecules are reoriented around the non-polar gas molecules to cause hydrophobic hydration, and so-called water structuring is achieved. As a result, the molecular movement of water in the cells of cut flowers is delayed, the viscosity of water is increased, the rate of enzymatic reaction is slowed, and metabolism is suppressed. By maintaining this state, freshness can be maintained for a long time. In this case, in cut flowers, the petals are generally thin, so that the nonpolar gas easily dissolves into the cells, so that the method of the present invention is particularly effective.

Generally, the solubility of non-polar gas in water is small, but according to the present invention, one that is relatively easy to dissolve in water is selected, and cut flowers are prepared so that the partial pressure in the container becomes a predetermined pressure. Since the partial pressure of the nonpolar gas in the container in which is stored is increased, the concentration of the nonpolar gas dissolved in water in the cut flower cells can be increased. If this predetermined pressure is high, the concentration of the non-polar gas in the water will increase, the structuring of water will proceed, and the effect of suppressing metabolism will increase. Therefore, this predetermined pressure is determined in consideration of the solubility of the nonpolar gas to be adopted, the type of cut flowers to be preserved, the intended preservation period, and the like. In this case, if the pressure in the container is increased, the weight as a pressure container is increased and the cost is increased, and it is disadvantageous in terms of handling for storage. By adopting a water-soluble material, it is possible to select a low pressure and eliminate such a disadvantage. Therefore, as the predetermined pressure, from the practicability of the present apparatus, a gauge pressure of up to about 5 atm is suitable, and a pressure of 3 atm or less is desirable.

Further, according to the present invention, since a non-active gas having low activity is used, even if this gas is dissolved in water in the cells of the flower, it is chemically stable, so that it can be used for intracellular biochemical reactions. Do not get involved. Therefore, this gas does not promote the living action of flowers. Further, since the container storing the cut flowers by pressurizing the non-polar gas as described above is maintained at a low temperature of about 10 ° C or lower, it is possible to maintain the general freshness by a low temperature environment and the temperature of water viscosity. Due to the dependence, the viscosity of cell water can be increased, and the effect of suppressing metabolism is further enhanced. In this case, not only the refrigerated warehouse in the production area, but if the cold storage state is continuously maintained from production to sale by using a cold storage truck or a cold box, not only the shipping adjustment period in the production area, The freshness of cut flowers can be maintained throughout the transportation and distribution process. It is desirable that the predetermined temperature is as low as possible from the viewpoint of maintaining the freshness of cut flowers, but it is easier to approach room temperature in terms of realizing a low temperature environment, so the type of cut flowers and the type of nonpolar gas used. A suitable temperature is selected depending on the pressure, pressure, etc.

It is a low value at 5 MPa and 1.47 MPa. Therefore,
Since it dissolves in the water of the cut flower cells with relatively low pressure,

According to the invention of claim 2, in addition to the operation of the invention of claim 1, since the nonpolar gas is collected before the cut flowers are taken out from the container, the nonpolar gas can be repeatedly used. For example, xenon gas, which is the most non-polar gas and is most soluble in water, is expensive. Therefore, by reusing the gas in this way, cost reduction for long-term storage of cut flowers can be achieved.

As described above, when a rose, which is an example of a cut flower, is stored at a low temperature under a pressure environment of xenon gas, the metabolism of rose cells is suppressed by the following phenomenon. Pressure container 1
By setting the initial partial pressure of xenon gas in the chamber to 3 kg / cm 2 G, xenon gas is sufficiently dissolved in water that is the main component of rose cells, and water molecules are reoriented around xenon gas molecules. Hydrophobic hydration then occurs and the water is structured. By thus structuring the water in the cells of the rose, the viscosity of the water is increased, the metabolism of the cells is suppressed, and the freshness of the rose is maintained for a long time. According to experiments by the inventors, the rose preserved for 2 weeks by this method maintained the same condition as at the start of preservation. That is, the freshness was almost completely maintained. On the other hand, the roses preserved simply by using the usual preservation method of keeping the low temperature showed "wiring" and changes in flower color, and some flowers were dropped, and the freshness was remarkably reduced.

Although an example of a rose has been shown above, the method of the present invention can be applied to any other flower, and a freshness-retaining effect can be obtained for them. In this case, usable nonpolar gases such as xenon gas have different solubilities in water, and when the pressure is increased, the solubilities are increased and the structuring of water is promoted, and the effect of maintaining freshness is increased. . Therefore, the pressure of the nonpolar gas is determined by comprehensively judging the type of gas to be used, the type of cut flowers to be targeted, the duration and degree of the desired freshness retention, and the like. For example, when a rose is stored for about two weeks using krypton gas, this gas has a lower solubility in water than xenon gas, and thus requires a pressure about twice that of xenon gas. However, since krypton gas is inexpensive, it is not always necessary to collect it, and if it is released into the atmosphere, it will be easy to handle for keeping freshness.
