Description

Mei-shosho Method for restoration and fixation of plant-derived green pigment by hot water bath, and heating container for fixing and fixing plant-derived green pigment

The present invention relates to a technique for restoring and Z-fixing plant-derived green pigments, including wild plants such as bracken radish, vegetables such as cucumber edamame, and seaweeds such as kelp and seaweed. Green plant-derived green pigments, such as green edible plants or four-leaf clover and fern leaves, which are originally green plants that are pressed flowers in wild plants, even after appropriate processing Ingestion of inorganic zinc as a trace mineral material incorporated into the dietary intake standard, which is effective for use to prevent fading or discoloration of the original green color, and which is beginning to attract attention recently. A new method of restoring and fixing plant-derived green pigment by a new water bath that effectively acts as a means, and a plant-derived green pigment restoring solid having a novel structure for the method It is what you try to provide a use heating container. BACKGROUND

—Generally, it is already well known that plants (including seaweeds) lose their green color and turn brown if the magnesium contained in chlorophyll is lost due to the oxidation of the polyphenols contained. It is also known that, once chlorophyll has turned brown, if it is immersed in a solution containing metal ions, the green color can be restored by the action of metal ions (metal chlorophyll) and the discoloration can be prevented for a while. Therefore, when fresh wild vegetables and vegetables are processed as appropriate and distributed as commodities, or when they are temporarily stored and consumed at home, etc., their properties are used. A number of techniques have been proposed to restore and / or fix the green pigment originally possessed by those plants. For example, (1) In the invention disclosed in Japanese Patent Publication No. 3-128686, There is a disclosure of a "color fading agent for plants that has faded" based on the technical concept of causing chlorophyll whose on color has faded to develop a green color. (2) Japanese Patent Publication No. 3-1-286867 A method for causing chlorophyll of a plant in a dead state to develop a green color ”discloses an invention in which chlorophyll, which has been bleached by the action of iron ions and copper ions, develops a green color. (3) Patent No. 30 The invention disclosed in Japanese Patent Application Laid-Open No. 82980/1990 (Japanese Patent Application Laid-Open No. 3-320309) is directed to a "method for restoring the green color of stored browning plants" in which chlorophyll faded by the action of copper ions is colored green. Is involved,

(4) The invention of "Recoloring method of salted vegetables and wild plants" in Patent No. 2 729 929 (Japanese Patent Application Laid-Open No. Hei 8-299858) is based on zinc ion as a main component. This is due to the action of zinc ions that restore the green color by pickling salted vegetables or wild vegetables in the heated solution. (5) Japanese Patent Application Laid-Open No. 6-2177332, “Green Vegetables and Seaweeds” The coloring method for coloring vegetable and seaweed chlorophylls to green by the action of copper ions, all of which disclose typical technical ideas for recoloring or coloring plant-derived green pigments. ing.

As described above, these conventional methods have been proposed to restore and / or fix the green pigment originally possessed or possessed by the plant with a solution containing iron ions, copper ions, and the like. Among them, the action of iron ions described in (1) and (2) above was based on the mixing of ferrous oxide with a mixed solution of citric acid and tartaric acid. The effect of the copper ions in (3) is obtained by adding a chlorophyll such as sodium copper chlorophyllin to an aqueous solution in which acid and ascorbic acid are dissolved. Further, the action of zinc ion in the above (4) depends on the treatment liquid containing zinc ion as a main component, and the remaining one in the above (5) is copper chlorophyll / copper chlorophyllin alkali gold. It is due to the action of copper ions in aqueous solutions containing genus salts and Liaoyuan.

As described above, in the case of the plant-derived green pigment restoration and Z or fixation method proposed previously, a metal ion solution is prepared using chemicals, both of which are metal compounds, and the plant is heated with the metal ion solution. Because they are processed, their image as a natural food product declines and the product value decreases. In addition to this, the applicant himself has already filed a patent No. 2911 1851 (Japanese Patent Application Laid-Open No. Hei 9-1111102) because it leads to the problem that consumers may have difficulty eating with peace of mind. Publication No.) to complete the method of restoring or maintaining the green color of edible plants and the color former pack used in this area, instead of adding a large amount of metal compounds artificially until then. A means of leaching plant ash in a solution to elute and utilize natural metal ions contained in plant ash has already been put to practical use, and it is possible to produce browned edible plants with excellent color without reducing the texture. In addition to being able to restore green, edible plants were processed to be green, and it was possible to restore the green color of edible plants that can be stored for a long time to green, or to preserve them after processing them to green.

In the present invention, the method of restoring and / or fixing plant-derived green pigment by using the metal ions in the natural world which has already been completed has been promoted, and while its spread has been gradually promoted, more convenient and reliable green pigment restoration and / or fixing has been achieved. We heard that there were many requests from various parties regarding the method, and we also added minerals as trace minerals that were newly incorporated into the mineral intake standards in the recently revised 6th Nutrition Requirements. Focusing on the positioning of zinc, taking advantage of this kind of accumulated technology that we have learned so far, we have worked diligently to develop and research effective trials and errors in order to complete effective technical measures that are an extension of it. As a result of repeating a number of trial production experiments, finally, a very effective and simple method for restoring and fixing plant-derived green pigments has finally been achieved. In the following, we succeeded in realizing a heating vessel for fixing and fixing plant-derived green pigment, which leads to efficient ingestion of trace minerals. In the following, the configuration of the heating vessel is described with some typical examples. I will explain to you. Disclosure of the invention

The method of restoring and fixing a plant-derived green pigment by hot water bathing, which forms the basis of the present invention, basically has the following configuration.

That is, planting is performed only by the interaction of copper ions and zinc ions eluted into hot water or hot water in a heating vessel formed with a structure in which the metal shell surface is exposed on the inner surface. This is a method for restoring and fixing the green pigment of a plant by boiling water, which has a structure that restores and / or fixes the green pigment derived from a product.

If this basic configuration is more specifically shown, it is formed into a structure in which a predetermined volume and shape are set, and at least a part of the inner surface that comes into contact with hot water or a part of the inner surface thereof is exposed. A heating container is filled with a predetermined amount of water, heated and heated to obtain hot water or hot water, and a green plant in an amount corresponding to the volume of the heating container is soaked for a predetermined time, and then the water is heated. Alternatively, without adding a chemical solution dedicated to metal ion treatment to hot water, green pigments derived from green plants can be produced solely by the interaction of copper ions and zinc ions eluted from the heating vessel material into the warm water or hot water. It is a method of restoring and fixing plant-derived green pigments by hot water roasting that has a configuration that allows restoration and Z or fixation.

The heating vessel must have a structure in which the metal shell 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. By promoting the ionization effect by the heating and heating means, the copper ions and zinc ions constituting the gunmetal are naturally dissolved in hot or hot water, and only the interaction between the natural copper ions and lead ions is achieved. The function of the method for restoring and fixing the green pigment of the present invention is as follows. As an essential element, therefore, the addition of an artificial chemical solution dedicated to metal ion treatment, which is adopted by all conventional means, at least restores and Z-fixes green pigment derived from plants That it is rather than employed for the purpose, it shall be processed exclusively by means by a hot water bath.

The structure of the heating container may be any of various structures described below as an invention related to the green dye restoration / fixing method which forms the basis of the present invention. In addition, water may be used as necessary. In order to increase the area of contact with the container, the inner surface of the container is made uneven, and an inner scythe or a kiln is used to insert and remove green plants. It is of course possible to employ conventional means as appropriate, such as using a metal member for the metal, and therefore, copper ions and the like that elute depending on the metal component, the structure of the heating vessel using the metal member, the heating conditions, etc. Although the elution amount of zinc ions and zinc ions vary, the value cannot be specified unconditionally, but experiments have confirmed that each ion has reached a maximum of about 10 PPM. It is necessary to set the appropriate time for the water bath within the optimal range, and even if a heating vessel of the same material and structure is used, the type and degree of fading of the target green plant, or the natural green color of the target plant Needless to say, it is necessary to adjust the time of hot water bathing depending on the degree of color of the water. Only by elution of zinc ion by hot water decoction using a zinc plating pot, the green pigment restoration / fixing action is extremely slow and varies, and the plant itself is extremely flexible as in the case of the above-mentioned conventional technology. Therefore, if the heating temperature of the solution containing zinc ions is lowered or the time for soaking is shortened to reduce the decrease in texture, the green color cannot be restored to a beautiful green color. It has also been confirmed that a new problem arises, which causes copper ions to be eluted together with zinc ions by using a heating vessel made of gunmetal, and in the case of hot water bathing due to the interaction of both, only zinc ions are used. In comparison, several experiments have repeatedly confirmed the fact that the efficiency of green pigment restoration and fixing is significantly improved.

On the other hand, in the case of elution of copper ions by hot water decoction using a copper pot, as in the case of the above-mentioned prior art, the plant can certainly be colored or colored to a beautiful green color, but a solution of copper ions for the treatment The naturally pickled plants naturally have a high copper content after treatment. Copper itself is originally contained in a small amount in plants, but if it exceeds the limit and it is artificially added with a large amount of copper, it is particularly in the body like edible plants. Therefore, the method of turning chlorophyll green by the action of a large amount of copper ions is not practical because it is not desirable because it is ingested and the health is harmed. Therefore, means for restoring and fixing plant-derived green pigments by hot water decoction using only natural zinc ions or copper ions are naturally included in those conventional technical ideas. In addition, these means are clearly distinguished from each other, and the use of the specified heating vessel of the present invention eliminates the natural zinc ions and copper ions. It builds an individual and independent technical idea of interaction. Related inventions

The present invention relates to a method for restoring and fixing plant-derived green pigment by hot water decay, which is the basis of the present invention, and includes a heating vessel for restoring and fixing plant-derived green pigment having the following configuration. .

In other words, the heat-resistant container body that is set to the volume and shape required for hot water decoction of an appropriate amount of green plants exposes the gunmetal ground to at least all or part of the inner surface that comes into contact with hot water. This is a heating container for restoring and fixing a plant-derived green pigment having a configuration formed to have a structure as described above.

The heating container for plant-derived green pigment restoration and fixation of this basic configuration consists of a heat-resistant container body that is set to the volume and shape required to boil an appropriate amount of green plant, and the entire body is made of gunmetal material. In addition, it was formed to have a structure that does not have a surface finishing layer so that at least the entire inner surface or a part of the inner surface that comes into contact with the hot water has the exposed metal shell surface exposed.

The present invention also includes a heating container for restoring and fixing a plant-derived green pigment, which has a structure in which a gunmetal ground is formed on the entire inner surface or a part of the inner surface so as to be exposed. In addition, the heat-resistant container body, which is set to the volume and shape necessary for boiling an appropriate amount of green plants, is made of a heat-resistant material other than metal such as fluororesin and ceramics. At least the entire inner surface or the part of the main surface that comes into contact with the hot water shall be made of a multi-layered material in which an appropriately thick surface layer made of a gunmetal material is laminated and integrated. The present invention also includes a heating container for restoring and fixing a plant-derived green pigment, which is formed so as to have a structure in which gunmetal ground is exposed on the entire inner surface or a part thereof.

Furthermore, the heat-resistant container body, which is set to have the volume and shape necessary to boil an appropriate amount of green plants, is made of a gunmetal material, and has a wall thickness in the inward direction. It is made of a multi-layer metal with an appropriately thick surface layer made of a heat-resistant metal material other than the gunmetal material on the inner surface of the main body, and the inner surface is A plant-derived green that has been polished until the gunmetal material, which is the part, is exposed, and has a structure in which the gunmetal ground is exposed on at least part of the inner surface that comes into contact with hot water. It also includes a heating vessel for element restoration and fixation.

Similarly, the volume and shape of the heat-resistant container body required to boil an appropriate amount of green plants are made of gunmetal material, and the thickness in the inward direction is reduced. It is made of a multi-layer material in which a suitably thick surface layer made of a heat-resistant resin such as fluororesin is laminated and integrated on the inner surface of the main part, and the main part is formed on the inner surface.

A heating container for dye restoration and fixation is also included.

The heat-resistant container body includes green plants, such as wild plants such as brackish springs and kogomi, which are required for restoring and / or fixing the plant-derived green pigment in the present invention. Green vegetables such as green vegetables and green seaweeds such as seaweed turtles are not only edible but also wild grass such as four-leaf clover and ferns leaves. Depending on the type of green plant, processing purpose, processing efficiency, etc., from the necessity of incorporating it into a part of a craft work for ornamental purposes, from the necessity of academic records and preservation, to the simple green plant to be pressed, This function fulfills the function of storing the predetermined amount determined by the above and safely filling the water required for hot water decoction. Therefore, in addition to having a shape and size enough to hold a predetermined amount of water necessary to achieve the function, and having a durable strength, various heat sources such as gas, heavy oil, kerosene, firewood, etc. It must be formed into a container that can exhibit sufficient heat-resistant strength even when heated by heat treatment. For processing plants, etc., for example, a bathtub-like box type, cylindrical type or tank Various types of containers such as molds and other shapes and structures, and small containers that are easy to handle, so-called pot-like containers, to be usable in ordinary households or as hobby or laboratory tools It can be a container with a shape and structure, combined with a lid to increase the efficiency of hot water bathing, and with handles, legs, trolleys, etc. convenient for moving, washing and other handling work.

The essential component of the heat-resistant container body is that it is formed so as to have a structure in which the base metal surface is exposed at least on the entire inner surface or a part of the inner surface that comes into contact with hot water. However, because of its constitution, the function of restoring and Z-fixing the plant-derived green pigment of the present invention is achieved, and therefore, the whole is made of a gunmetal material as described later. This is the most basic structure that is formed without a coating or other surface finishing layer so that at least all or a part of the inner surface that comes into contact with hot water exposes the metal shell surface. In addition to being formed as a material, it must be formed in the following structure.

The inner surface of the main body is made of a heat-resistant metal material other than gunmetal material, for example, a coating material made of titanium, tin, etc. It is made of a multi-layered metal that is laminated and integrated, such as by laminating or evaporating these materials to form a layer, such as laminating, and the main metal part is exposed on the inner surface. Even with a polishing finish up to this point, it is possible to realize the "structure in which the metal shell surface is exposed at least on the inner surface that comes into contact with hot water" in the present invention.

Gunmetal is used in the construction of bearings, steam pipe parts, marine parts, and as far as the construction of artillery, as the name implies, and is known as a type of bronze. However, the gunmetal in the present invention excludes gunmetal that does not contain zinc (Zn) (for example, tough pitch copper or aluminum copper excluding a part thereof), and In addition, zinc ions and copper ions must be dissolved in warm water, albeit in a small amount, so that they cannot be achieved with other metal ions as in the prior art. Chlorophyll green in the formation of zinc chlorophyll and copper chlorophyll It is intended to achieve the inherent function of developing or recoloring the color and stabilizing the fixing of the green color, particularly, thermally. For the purpose of providing the same function, a zinc alloy containing copper (Cu), which is terminologically out of the category of gunmetal, is considered to be the same kind of material as the gunmetal in the present invention. Included in gunmetal. BRIEF DESCRIPTION OF THE FIGURES
