2. Description of the Related Art In general, it has been well known that plants (including seaweeds) lose their green color and turn brown when the magnesium contained in the chlorophyll is lost due to the progress of oxidation of the contained polyhenol. It is also known that chlorophyll that has once turned brown can be restored to its green color by the action of metal ions (metal chlorophyll) when immersed in a solution containing metal ions, and that fading can be prevented for a while. Therefore, when the fresh wild plants and vegetables are appropriately processed and distributed as products, or when they are temporarily stored and consumed by ordinary households, etc. A number of techniques for restoring and / or fixing the green pigment originally possessed by these plants have been proposed so far.

For example, in the invention disclosed in (1) Japanese Patent Publication No. 3-12866, there is a "color fading agent for plants" based on the technical idea of making chlorophyll whose iron ion is fading colored green. In (2) Japanese Patent Publication No. 3-12867, "Method of developing chlorophyll in bleached and depleted plant into green color", chlorophyll in bleached color due to the action of iron and copper ions is developed into green. The invention which is made to do so is shown, and (3) Patent No. 3082980
The invention disclosed in Japanese Patent Laid-Open No. 3-302309 relates to a "green restoration method for a storage browning plant" in which chlorophyll that has been discolored by the action of copper ions is colored in green, No. 2729929 (JP-A-8-29)
No. 8958) discloses a method for recoloring salted vegetables and wild vegetables. The invention is based on the action of zinc ions, in which salted vegetables and wild vegetables are soaked in a heating solution containing zinc ions as a main component to restore the green color. (5) JP-A-6-217732
The "coloring method of green vegetables and seaweeds" of the publication is a method of coloring chlorophyll of vegetables and seaweeds to green by the action of copper ions, and both are typical for recoloring or coloring plant-derived green pigments. Various technical ideas are disclosed.

As described above, these already proposed conventional methods restore and / or restore the green pigment originally possessed by the plant or possessed by the solution with a solution containing iron ions, copper ions and the like. It was based on the technical idea of fixing it, but among them, the above (1) and (2)
The action of the iron ion is due to the metal ion treatment-specific chemical solution obtained by mixing ferrous oxide with the mixed solution of citric acid and tartaric acid, and the action of the copper ion of (3) is
This is due to a mixed solution obtained by adding chlorophylls such as sodium copper chlorophyllin to an aqueous solution in which an acid and ascorbic acid are dissolved. Further, the action of zinc ion in (4) is mainly composed of zinc ion. Depending on the treatment liquid,
The remaining (5) above is due to the action of copper ions in the aqueous solution containing copper chlorophyll, copper chlorophyllin alkali metal salt, and a causative agent.

Thus, in the case of the plant-derived green pigment restoration and / or fixing method which has been proposed in the past,
All are made of chemical compounds that are metal compounds to make metal ion solutions, and plants are heat-treated with this metal ion solution, which reduces the image as a natural food and reduces the commercial value. Not only
Since this leads to the problem that consumers will find it difficult to eat with peace of mind, the applicant of the present application has already filed patent No. 29118.
No. 51 (Japanese Unexamined Patent Publication No. 9-110252) completed "a method of restoring the green color of an edible plant or keeping it green and a color developer pack used for this purpose", and artificially large amounts of metal compounds up to that point. Instead of adding, the means for leaching the plant ash in the solution to elute and utilize the natural metal ions contained in the plant ash has already been put into practical use, and the browned edible plants can be used without reducing the texture. It makes it possible to restore an excellent green color, and to treat the edible plant to green, restore the green color of the edible plant that can be stored for a long time to green, or store it in the state treated to green. I did it.

In the present invention, the method for restoring and / or fixing the plant-derived green pigment by the metal ion of the natural world which has already been completed is put into practice, and while it is gradually spread, more simple and reliable restoration of green pigment and / or In addition to hearing that there are many requests from various parties regarding the fixing method, inorganic zinc as a trace mineral material newly incorporated into the mineral (mineral) intake standard in the recently revised Sixth Nutrition Requirement Focusing on the positioning of this, taking advantage of this kind of technology accumulation that we have learned so far, in order to complete effective technical means located on the extension of it, we have earnestly conducted development and research, repeated trial and error, and As a result of repeating the trial production experiment, it finally came to a very effective and convenient method for restoring and / or fixing a plant-derived green pigment, and In the following, we succeeded in realizing a heating container for restoration and fixation of plant-derived green pigment that also leads to efficient intake of trace minerals.Hereinafter, the configuration will be described in detail with some representative examples. I will explain to you.

[0007]

The method of restoring and fixing a plant-derived green pigment by hot water bath forming the basis of the present invention basically has the following constitution. That is, the plant-derived green pigment is restored and / or fixed only by the interaction of copper ions and zinc ions eluted in hot water or hot water in a heating container formed with a structure with an exposed gunmetal surface on the inner surface. This is a method for restoring and fixing the green pigment of a plant by hot water boiling, which has the above-mentioned composition as a gist.

More concretely showing this basic structure,
The heating container is set to have a predetermined volume and shape, and has a structure in which the surface of the gunmetal is exposed on all or part of the inner surface that will come into contact with at least hot water. , After heating to hot water or hot water, soak the green plant in an amount commensurate with the volume of the heating container for a predetermined time and boil in hot water, and add the chemical solution for metal ion treatment to the hot water or hot water. In other words, a hot water bath with a structure that restores and / or fixes a green pigment derived from a green plant solely by the interaction of copper ions and zinc ions eluted from the heating container material into the hot water or hot water. It is a method of restoring and fixing plant-derived green pigment.

[0009] The heating container must be formed to have a structure in which the gun metal surface is exposed at least on the entire inner surface or a part of the inner surface that comes into contact with the hot water. As the ionization effect is promoted by heating and heating means, copper ions and zinc ions that compose gunmetal are naturally eluted into hot water or hot water, and only the interaction between these natural copper ions and zinc ions To restore and / or fix the plant-derived green pigment (including prevention of color development and fading. The same applies hereinafter), and is a component of the method for restoring and fixing green pigment of the present invention. Therefore, the addition of the artificial chemical solution exclusively for the metal ion treatment adopted by all the above-mentioned means restores and / or fixes the plant-derived green pigment at least. Not be employed for the purpose, it shall be processed exclusively by means by a hot water bath.

As the structure of the heating container, it is possible to employ various structures which will be described later as an invention related to the green dye restoration / fixing method which is the basis of the present invention. In order to increase the contact area with water, the inside surface of the container has an uneven shape, and inner sickles and baskets for inserting and removing greenish plants are combined, and the whole or one of the inner sickles and baskets is Of course, it is also possible to adopt appropriate conventional means such as using a gunmetal member for the part,
Therefore, the gunmetal component and the structure of the heating container using it,
Although the amount of copper and zinc ions to be eluted varies depending on the heating conditions, etc., the values cannot be generally specified, but according to the experiment, each ion has a maximum of 10 PPM.
It has been confirmed that the temperature has reached a certain level, and it is necessary to set the time for boiling water in the optimum range according to the degree of elution, and even if a heating container of the same material and structure is adopted, It goes without saying that it is necessary to adjust the time for boiling water depending on the type and the degree of fading of the green-colored plant, or the degree of the original green color of the plant.

[0013] The elution of zinc ions by hot water roasting using a galvanizing pot has a very slow and variable green pigment restoration / fixing action, and moreover, as in the case of the above-mentioned prior art, the plants themselves remarkably grow. It has the property of becoming soft, and for that reason, if the heating temperature of the solution containing zinc ions is reduced or the Manzuke time is shortened in order to reduce the texture deterioration, it will not be possible to restore a beautiful green color. It has also been confirmed that a new problem will occur, which is that a heating vessel using gun metal causes copper ions to elute along with zinc ions, and in the water boiling due to the interaction of both, it is compared with the case of only those zinc ions. However, the fact that the green dye restoration / fixing efficiency is significantly improved can be repeatedly confirmed by several experiments.

On the other hand, in the case of elution of copper ions by hot water roasting using a copper pot, it is possible to develop or color a plant to a green color of a clean color as in the prior art, but copper is required for the treatment. Plants soaked in an ionic solution naturally have a high copper content after treatment. Although copper itself is originally contained in a small amount in plants, it is ingested into the body like an edible plant especially when it exceeds the limit and artificially adds a large amount of copper. Therefore, the method of turning chlorophyll into a green color by the action of a large amount of copper ions is limited in its range of use and lacks practicality. Means for restoring and fixing plant-derived green pigments by hot-water bathing with only natural zinc or copper ions are not naturally included in the technical ideas that have been used up until now. Is a clear distinction, and the establishment of individual and independent technical ideas of the interaction of natural zinc ion and copper ion by adopting the specified heating container of the present invention. Is shall.

The main body of the heat-resistant container is a greenish plant to which the present invention is required to restore and / or fix the green pigment derived from plants, for example, edible plants such as bracken, mainspring and kogomi, and cucumber and Green vegetables such as edamame and green edible plants that also include green seaweeds such as kelp and wakame are not used for food, but they are wild plants such as four-leaf clover and fern leaves. Depending on the type of green plant, processing purpose, processing efficiency, etc., it is necessary to incorporate it into a part of a craft work for ornamental use, academic records, preservation etc. to simple green plants to be pressed flowers.
