Description

  According to the present invention, tea leaves or tea powder is coated with a water-soluble antioxidant, and is antioxidant until used, and when used, the coating becomes water-soluble and tea leaves or tea powder and water are mixed to give tea. The present invention relates to a method for producing filter-packed tea that can be put in water together with coated tea leaves or tea powder and a bag.

Traditionally, tea has been stored and used in tea cans. Since the tea canister is opened each time it is used, new air enters each time and oxygen is supplied, so oxidation has gradually progressed and browning has often been observed. Under such circumstances, the flow of opening only the used portion at the time of use has been developed as an “instant drink” without being influenced by the frequency of use.
The first one is packaged in a sachet for each usage.
The second is disclosed in Patent Document 1 in which tea is molded into a tablet, and in Patent Document 2, malt sugar is added to facilitate molding, and trehalose is added to prevent oxidation. Has been disclosed.
Third, Patent Document 3 discloses an instant powder tea containing catechins, oxalic acid, and cyclodextrin.
Fourthly, Patent Document 4 discloses instant powdered tea using green tea extract and green tea leaves or tea powder.
In the former two examples, there is a problem that solidification is not possible unless maltose is added in tableting, and there is a disadvantage that the original taste of tea changes because it is added in a large amount. The treatment with trehalose also affects the original flavor of tea because it is applied to tea. In the latter two examples, even if the tea extract is brought close to the original tea taste by instantization of the main role, it does not make use of the original tea flavor. Dim Sum culture is not just for nutrition. There is a demand for the development of tea cultivated in tradition.
In addition, when the tea itself is put in a small bag, the bag is broken at the time of use and the contents are put into water, and the tea leaf itself is not preferable because it remains in the mouth when drunk. Moreover, it is easy to put tea leaves or tea powder in a wide-mouth bottle, but there is a drawback that it is difficult to put in a narrow-mouthed container such as a PET bottle.

A filter substrate sheet-like base material having a water-soluble anti-oxidant-coated tea is attached to the sheet-like substrate of the filter body made of a water-insoluble material, and this is attached to the sheet-like base body of the filter body. It is characterized by covering with.

Invention of Claim 2 is a manufacturing method of filter body packaging tea,
The mixture of tea leaves or tea powder and tasteless, odorless and edible water-soluble powder in a desired ratio is passed through water, and the mixture has a large number of openings with a size that prevents the tea leaves or tea powder from passing therethrough. Place a filter body with a water-soluble material on a sheet-like substrate, supply a desired amount of water, through which the tea powder is attached and coated with water-soluble antioxidant powder, and at the same time Then, after the coated tea powder is attached to the sheet-like substrate, it is covered with a sheet-like lid of the filter body in an appropriately semi-dried state.

Since it is configured as described above, in the water-soluble antioxidant-coated tea that is a tea leaf or tea powder coated with the water-soluble antioxidant according to the method for producing the filter body packaged tea of the present invention, before use, Oxidation can be prevented, and only the portion of the bag that is used during use can be put into water, and the antioxidant will dissolve in the water, and the tea leaves or tea powder will be mixed with water so that tea can be drunk. The packaged tea leaves or tea powders are convenient for carrying.

It is a figure which shows one embodiment of the water-soluble antioxidant covering tea which concerns on the manufacturing method of filter body packaging tea by this invention, filter body packaging tea using this, and a tea packaging aggregate. It is a figure which shows another one embodiment of the water-soluble antioxidant coating | coated tea which concerns on the manufacturing method of the filter body packaging tea by this invention, filter body packaging tea using this, and a tea packaging aggregate.

The method for producing a filter body-packed tea according to the present invention is characterized by a method of coating a water-soluble antioxidant with a moderate amount of water and a method of sandwiching coated tea with a filter material.
Examples will be described below.

As a material for the anti-oxidation coating of a tasteless, odorless and edible water-soluble film for coating the tea leaves or tea powder used in the present invention, pullulan, porphyran, oblate, starch derivative, glucomannan and the like are known. It has been. A powder having a diameter of about 40 to 200 μm can be used. Since these antioxidant coating powders are dissolved according to the amount of water, when an appropriate amount of water is applied to the tea leaves or tea powder, the antioxidant coating powder is sprayed onto the tea leaves or tea powder using water as a medium. The tea leaves or tea powder is covered. Since the space between the powders is filled with the powder of the antioxidant coating dissolved in water, the tea is blocked from the air and can be prevented from being oxidized, and the flavor and color of fresh tea can be maintained.
In use, when the package in which tea is sealed is put into tea bowl or bottle water, it enters into a large amount of water, and the powder of the antioxidant coating is completely dissolved, and tea leaves or tea powder is mixed with water to produce tea.

FIG. 1 is a view showing an embodiment of a water-soluble antioxidant-coated tea, a filter-packed tea using the same, and a tea-packed assembly according to the method for producing a filter-packed tea according to the present invention.
The state of coating of tea leaves or tea powder and the powder of the antioxidant coating also depends on the amount of water.
1-A shows a state in which the powder 102 of the antioxidant covering body surrounds the individual of the tea leaf or tea powder 101, and the water particles 103 are present in the form of intermediary between them.
The tea leaves or tea powder 101 contains water particles 103, and the water particles 103 dissolve the powder 102 of the antioxidant coating, so that the affinity between them is good. The tea leaves or tea powder 101 is coated with the powder 102 of a large number of antioxidant coatings. For this reason, the tea leaves or tea powder 101 is blocked from air and is prevented from being oxidized.
1-B shows a state in which a plurality of tea leaves or tea powders 101 coated with the powder 102 of the antioxidation coating are gathered as in 1-A. Although not shown here, some of the tea leaves or tea powder 101 are coated with the powder 102 of the antioxidant coating, and a mixture of these is also conceivable. In any case, a coated tea leaf or tea powder that is prevented from oxidation is produced.

In the filter body having a large number of openings that do not allow the passage of tea leaves or tea powder, the size of the openings should be such that the tea leaves or tea powder do not pass, or if tea dissolved in water can pass through. Less than that is preferable because it is good. Considering a tea leaf or tea powder size of 16 mesh or less, a smaller size is preferred. The opening may be a hole opened in the film forming the filter body, a net hole knitted in a net shape, or a fine gap that allows water to pass through like a paper filter. Of course, the material needs to be non-toxic, tasteless, odorless and water-insoluble. Suitable materials for this include paper, polyolefins such as polypropylene, PET, PTFE, and the like. Paper is advantageous because it is inexpensive and easy to process after use, and does not cause environmental problems when discarded.

In 1-C, desired water particles are given to the entire sheet-like substrate 104 of the filter body, and from this, the above-mentioned antioxidant coating body powder 102 shown in 1-A and 1-B is coated. When the coated tea leaf or tea powder 100 is sprinkled, the coated tea leaf or tea powder layer 105 adheres on the sheet-like substrate 104 with an appropriate thickness. On this, a filter-like sheet-like cover 106 is further placed and pressed. You may insert the sheet | seat of the said antioxidant covering body on the sheet-like base | substrate 104 or the sheet-like cover body 106 below. In addition, it has shown that the unit of the rectangle divided | segmented with the dotted line respond | corresponds to one time used for drinking. It is unrelated to the fact that the break is visible.
Of course, the coated tea leaves or the tea powder layer 105 can be formed on a substrate that is not a filter body.

In 1-D, the place for 1 time used for drinking is expanded and the sheet-like base | substrate 104, the covering tea leaf or tea powder layer 105, and the sheet-like cover body 106 are shown.
In place of the sandwich body of the coated tea leaf or tea powder layer and the filter body, although not shown in the figure, it is of course easy and convenient to put the coated tea leaf or tea powder layer into the bag of the filter body and separate it. It is.

In 1-E, a plurality of sandwich bodies (1-D 110) of covered tea leaves or tea powder layers sandwiched between sheet-like filter bodies are shown sealed in an aluminum bag 111. It is not always necessary to use an aluminum bag.
When the sandwich is light transmissive, a light blocking bag is preferred so that sunlight does not hit the tea. It is convenient if the perforations 112 are easy to separate one by one. Moreover, it is convenient if there is an easy-to-break portion 113 so that the bag here is easy to tear.

Without being oxidized until use, in use (drinking), the sandwich body 110 can be put entirely in a glass or a plastic bottle containing water, easy to insert, water passes through the filter body, The antioxidant coating that is the coating of the coated tea leaves or tea powder layer 105 is melted, and the tea leaves or tea powder and water are mixed together. This can be used for drinking as tea.

FIG. 2 is a view showing another embodiment of the water-soluble antioxidant-coated tea, the filter-packed tea using the same, and the tea-packed assembly according to the method for producing a filter-packed tea according to the present invention.
In FIG. 1-C, the sheet-like substrate 104 of the filter body is in a flat state, but in FIG. 2, it has a storage recess for containing a coated tea leaf or tea powder layer. In 2-A, the sheet-like base body 201 of the filter body is provided with a large number of storage recesses 202 for containing coated tea leaves or tea powder layers. The coated tea leaf or tea powder is covered with this, and it is put on with a spatula to remove excess coated tea leaf or tea powder, and an appropriate amount of the coated tea leaf or tea powder can be left in the storage recess 202. Alternatively, it is possible to leave only the coated tea leaves or tea powder fitted in the storage recess 202 by tilting slightly and dropping the coated tea leaves or tea powder from above. In addition, as shown in the cross-sectional shape when cut by the cutting plane 203 for showing the cross section, the 2-B is composed of only the filter body 204, and the 2-C is further provided with an antioxidant coating. The cross section which attached the sheet | seat of the body 205 is shown. The shape of the storage recess 202 does not have to be a rectangular parallelepiped, and any recess such as a hemisphere, a cone, or a polygonal cone is possible.

Next, an example of a method for producing a sandwich body of a coated tea leaf or tea powder layer and a filter body is shown.
First, in the case of tea leaves, they are used as they are, but in tea powder, tea leaves are drawn with a mortar to make tea powder. The particle size is preferably smaller than 16 mesh. When water is given to the tea leaves or tea powder, the tea leaves or tea powder first gather together to enlarge the tea aggregate. On the other hand, while mixing tea leaves or tea powder and water-soluble antioxidant in a desired ratio well, give fine mist-like water particles, or mix the mixture in the space where water particles are given at a desired humidity. Upon exposure to exposure, the mixture collects water and collects, and the coated tea leaves or coated tea powder falls down.

When the sheet-like substrate of the wet filter body (for example, Japanese paper) is passed under the coated tea leaf or the coated tea powder while moving to a semi-dry state in a desired drying process, the coated tea leaf or A coated tea powder is obtained. It is also possible to press this. Since it is easily attached with water, a sheet of a water-soluble antioxidant may be attached on a sheet-like substrate. After that, when the sheet-shaped lid of the filter body is pressed on the sheet-shaped substrate on which the coated tea leaf or the coated tea powder is adhered, the 1-D coated tea leaf or tea powder layer and the filter body sandwich are formed. can get. In this case, it is possible to cut every appropriate unit or to take up a roll.

In addition, instead of moving the sheet base of the wet filter body while moving under the coated tea powder, the fallen coated tea powder can be scooped up and sprinkled on the sheet base of the filter body or raised. Is possible. After that, the sandwich body is cut in a size for one use, and a desired number is sealed in an aluminum bag as in 1-E. Alternatively, the desired number is sealed in one aluminum bag. In addition, a mixture of tea powder and water-soluble antioxidant powder mixed in a desired ratio is placed on the sheet-like substrate of the filter body, and then an appropriate amount of water is supplied and water is passed through the water. Brown powder adhesion and coating is performed by the powder of sex antioxidant material, at the same time, a method of adhesion state onto the sheet substrate of the coated tea powder is made is also possible convenient.

Coated tea powder coated with a water-soluble antioxidant as described above prevents the tea from oxidizing by blocking the air during storage, and the water-soluble antioxidant is water during use. The tea leaves or tea powder will dissolve in the water, making it compatible with water and drinking. Moreover, since the filter body does not put out tea leaves or powders of a certain size or more into the water, there is no need for solids to enter the mouth when drinking.
Such packaged tea can be drunk in tea bottles, tea bowls, etc. by putting the covered tea leaves or the tea powder layer and the filter body sandwich together with water, or if pre-filled with water. become. Further, as shown in 1-E, the sandwich body of the coated tea leaf or tea powder layer and the filter body may be further packaged in an aluminum bag, a polymer resin bag or the like in a batch or in a sealed manner.
Needless to say, tea includes tea, coffee and decoction herb tea in addition to green tea.

When tea is stored in a filter-only package without air-permeable water-soluble antioxidant coating, water is allowed to pass through. Absent. It is important that the coating is soluble in water without allowing air to pass, and that tea is stored therein.

Furthermore, the conventional ones of Patent Documents 1 to 4 use an extract, add an antioxidant treatment to tea itself, or add something other than tea such as maltose for tableting. According to the invention, tea itself does not need to be treated, but respects the original tradition of tea culture.
The degree of sealing of the coating for preventing oxidation is most preferably sealed, but even if it is not a complete seal with a part opened, an effect can be obtained because of different air entry.

As described above, the water-soluble antioxidant-coated tea according to the method for producing the filter-packed tea of the present invention can prevent oxidation before use, and the tea can be drunk only by putting the whole package into water at the time of use. Therefore, since it is very convenient and effective, the industrial applicability is extremely large.
