JP 2002-105369 (paragraphs (0005) to (0008)) JP2003-47444 (paragraph (0008)

Conventionally, it has been known that characters and figures are printed on food by inkjet method, but especially when printing on edible seaweed, the background color is close to black, so how to print white is a problem. It was. Further, other colors were also lost to black, and it was difficult to sufficiently develop colors.

When forming a white figure on laver or the like, it has been conventionally performed to finely pulverize the egg cake and apply it together with an adhesive to form letters and figures. In this case, there is a problem that the egg yolk powder does not pass through the ink jet nozzle well and the nozzle is clogged. Another problem is that unevenness occurs if the ink is not stirred immediately before use. In addition, when these measures are taken, the eggshell particles are finely divided into fine powders or calcium hydroxide crystals are used, resulting in a problem that the white color becomes thin and a good white color cannot be printed. It was.
For this reason, white printing on seaweed or the like has been carried out by screen printing using the above-mentioned finely pulverized eggshell particles having a certain size and kneaded with an adhesive. For this reason, printing of a fine pattern and printing on a large uneven surface have been difficult.

  The present invention solves the problems of the above-described conventional white ink for food. That is, the present invention aims to provide an ink that can be printed by an ink jet method, does not cause clogging of an ink jet nozzle, and can form a good white color even on uneven black laver.

Solution

In order to solve such a problem, in the present invention, printing is performed on laver using powder obtained by finely pulverizing the white portion of the shell and ink jet ink using infant milk as a spreading agent.
As a result, a food inkjet ink having excellent food safety and a good white color can be obtained.

Also, printing on laver using ink-jet ink further including maple syrup, shellac and the like.
Thereby, the adhesive force of the powder which finely pulverized the white part of the shell to a foodstuff can be improved.

  In addition, by blending an appropriate amount of a wetting agent, an ink can be obtained in which the nozzle at the tip of the inkjet does not clog due to drying. Specific examples include glycerin, propylene glycol, sorbitol, and other edible solvents, which may be used alone or in combination of two or more.

  Furthermore, you may add a preservative as needed. Examples of the preservative include ethyl alcohol, benzoic acid, sodium benzoate, sorbic acid, potassium sorbate, sodium dehydroacetate, isobutyl paraoxybenzoate, and the like. In order to keep sodium carbonate well in the ink, a surfactant such as a pH adjuster, sucrose ester, polyglycerin fatty acid ester, sorbitan fatty acid ester, and a silicone-based antifoaming agent should be added as necessary. Is also possible.

The ink-jet ink is mainly used for printing on edible seaweed and baked seaweed, but other foods such as cookies, biscuits, chocolate, kamaboko, and chikuwa can also be targeted.

The invention's effect

  As described above, the present invention can provide a good white ink-jet ink for use in foods. Further, the ink can show a good color even with foods based on black such as seaweed based on this white color and adding red food (eg, “Red No. 3”).

  The ink of the present invention mainly contains water, alcohol, a powder obtained by finely pulverizing the white portion inside the shell, and if necessary, a water-soluble resin such as a wetting agent, shellac, and other additives such as infant milk as a spreading agent. It is obtained by mixing, stirring, and further heating if necessary. The ink-jet ink prepared as described above is filled in a continuous type or drop-on-demand type ink jet printer for practical use.

  Ink-jet ink made by mixing the white part of shellfish with finely pulverized powder, a powder with a calcium content of 38% or more and a particle size of 1-8 um (hereinafter referred to as calcium powder), alcohol, and infant milk as a spreading agent To print on the seaweed. The apparatus used for printing is shown in FIG. The ink shown above is put into the ink tank 1. The ink is sent to the nozzle 2 having a diameter of 30 μm through the pipe and is placed on the platen 3 by the roller 4 one by one from the table 6 storing the nori sheet 5, and the characters are moved by the lateral movement of the nozzle 2 and the vertical movement of the nori sheet 5, A figure is formed as shown in FIG.

  Here, 10 g of calcium powder, 2 cc of infant milk, and 10 cc of absolute ethanol were stirred at room temperature and printed on an edible nori sheet. I was able to. When the milk for infants is less than this, precipitation separation is likely to occur, which is not preferable as an inkjet ink. (See Table 1)

  Moreover, when there is more infant milk | milk than this mixing | blending, a sticky feeling is high and drying takes time and it is unpreferable (Table 1). Infant milk also functions as a glue for the ink to adhere to the edible seaweed sheet, as a spreading agent for the ink, and to prevent precipitation of calcium powder in the ink. In addition, the result of using the same amount of fermented milk drink as the infant milk instead of the infant milk is almost the same print result.

  Printing on seaweed is performed using the inkjet ink prepared by mixing calcium powder and alcohol as shown in Example 1 and infant milk and shellac as spreading agents.

Here, 10 g of calcium powder, 2 cc of normal concentration infant milk specified by the product, 10 cc of shellac 15% ethanol solution, and 10 cc of absolute ethanol were stirred at room temperature and printed on an edible laver sheet. It was possible to perform printing with higher adhesion than in the first embodiment. The composition shown in Table 2 was tested, and a ratio of 10 g of calcium powder, 2 g of infant milk having a normal concentration designated by a product, 10 cc of shellac 15% ethanol solution, and 10 cc of absolute ethanol is preferable. (See Table 2)
Here, as an ethanol solution of shellac, for example, a solution obtained by dissolving a trade name “Rack Glaze 25E” sold by Nippon Shellac Industry Co., Ltd. can be mentioned.

Here, the same effect can be obtained by using pectin, duran gum, carrageenan or the like as a spreading agent instead of the shellac solution.
In addition, adding about 2 cc of maple syrup, honey or chickenpox together with shellac improves ink spread and softens the bitter taste of shellac. Since it does not change, it can be added as appropriate.

When printing on laver using inkjet ink prepared by mixing calcium powder, alcohol, and infant milk as a spreading agent shown in Example 1, 10 g calcium powder, 2 g infant milk, absolute ethanol An ink prepared by thoroughly stirring 10 cc at room temperature was filtered through a 10 μm membrane filter to prepare an ink jet ink.
When this ink was used to print on an edible laver sheet, the ink-jet ink was not clogged even after printing for a long time, and a good white color could be emitted.
In addition, although 1 to 3 grams of glycerin was added as a moisturizing agent and printing was performed, there was no particular effect on printing. Glycerin as a humectant can be added as appropriate. The other moisturizers described above are considered to be similar.

When printing on laver using ink for inkjet prepared by mixing calcium powder, alcohol, and infant milk as a spreading agent shown in Example 1, 10 g of calcium powder, the normal concentration specified by the product An ink jet ink was prepared by filtering an ink prepared by sufficiently stirring 2 cc of infant milk and 15 cc of absolute ethanol at room temperature through a 10 μm membrane filter.
When this ink was used to print on an edible laver sheet, a good white color could be emitted.

  When printing on laver using ink jet ink in which calcium powder, alcohol, and shellac alcohol solution shown in Example 1 are mixed at room temperature, 10 g of calcium powder, 10 cc of shellac 30% ethanol solution as a spreading agent, anhydrous An ink prepared by thoroughly stirring 10 cc of ethanol at room temperature was filtered through a 10 μm membrane filter to prepare an ink jet ink. (See Table 3)

  When this ink was used to print on an edible laver sheet, the ink-jet ink was not clogged and a good white color could be emitted. This ink is also suitable for people who are allergic to dairy products.

Printing on seaweed is performed using inkjet ink prepared by mixing calcium powder and alcohol, baby milk as a spreading agent, and water shown in Example 1.
Here, 10g calcium powder, 2cc infant milk of normal concentration specified in the product, 10cc absolute ethanol, and 4cc water were used to stir well at room temperature and printed on an edible laver sheet. Also, a good white color could be emitted. At this time, it is possible to adjust the ink drying time according to the amount of water. (See Table 4)

First, a graphic or the like is printed on an edible film using the inkjet ink prepared by mixing the calcium powder shown in Example 1, alcohol, and infant milk as a spreading agent (FIG. 3). The edible film 7 is preferably a film mainly composed of agar, gelatin, shellac or the like. First, an edible film is formed with gelatin on the release paper 8. Next, characters and figures are printed on the edible film by screen printing or ink jet printing. The figure shown in Fig. 2 can be considered. Thereafter, the edible film is peeled off from the mount 8, and moisture, alcohol, or the like is sprayed on the adhesive surface to enhance compatibility with the edible laver sheet 5. Here, the same effect can be obtained by spraying moisture and alcohol on the edible laver sheet 5. Further, when milk for beverage is sprayed, the compatibility is further improved and a good adhesive force can be obtained.
After that, the edible film is pressure-bonded to the seaweed, and the characters and figures can be drawn on the seaweed by transferring the letters and figures.

  Here, 2g of calcium powder, 2cc of baby milk of normal concentration specified in the product, 10cc of absolute ethanol, 10cc of ethanol solution of shellac 20% are printed on an edible film using ink prepared by stirring well at room temperature. preferable. When there is more infant milk than this composition, a sticky feeling is high and drying takes time, and it is not preferable.

It is also possible to form an edible layer on an edible laver sheet that is an object to be printed, and to print characters and figures thereon using the inks described in the first to sixth embodiments. The edible film layer is preferably a film mainly composed of agar, gelatin, shellac or the like.
Gelatin is first applied to one side of the edible seaweed sheet to form a gelatin layer on the surface. It is also possible to print figures and the like using the inkjet ink shown in Embodiments 1 to 6 prepared by mixing calcium powder, alcohol, and infant milk as a spreading agent with this edible layer. Furthermore, it is also possible to perform screen printing using the same ink.

  As described above, printing characters and figures on foods using the inkjet method, especially when printing on black sheet-like foods (such as baked seaweed), the background color is close to black, so how white is printed. Useful when you want to. It is also effective when printing light colors on black food.
