JPS62155068A - Laver sheet with pattern - Google Patents

Abstract

PURPOSE:In producing laver sheet having a printed patter layer on the surface, to improve contrast, clarity, etc., of the pattern, by using white ink containing white inorganic powder as ink for forming the printed pattern layer. CONSTITUTION:White inorganic powder such as calcium carbonate, calcium phosphate, etc., is blended with a binder (e.g., thick malt syrup or dextrin), etc., kneaded by a ball mill, etc., and made into a pasty state to product white ink. Then, a pattern is formed on the surface of the laver sheet by using this white ink by silk screen method, etc., Consequently, since the ink used contains the white inorganic powder having strong opacifying power, the formed pattern is not influenced by the ground color of the laver sheet and the patterned laver sheet having high contrast and clarity can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a patterned sheet of seaweed, and more particularly to a sheet of seaweed that is highly safe and has an excellent colored pattern.

(Prior Art) Patterned sheets of seaweed, in which patterns such as letters and figures are added to the surface of sheets of seaweed, are conventionally known. This kind of patterned sheet nori is
It is obtained by adding patterns to the surface of sheet nori using food coloring or natural coloring.

(Problem to be solved by the invention) The conventional patterned sheet nori as described above is colored with food coloring on a relatively dark surface such as black-purple to green, and the food coloring is generally hidden. It is reported that because the strength is low, it is almost impossible to impart high-contrast patterns on the surface of sheet nori, especially white, yellow, red, or other useful hues.

Therefore, it is desired to provide a clear pattern with excellent contrast despite the dark background color of plate nori.

(Means for Solving the Problems) That is, the present invention provides a patterned board laver having a printed pattern layer on any part of the surface, in which the printed pattern layer is
This is a specially selected board of seaweed characterized by being formed with white ink containing white inorganic powder.

Next, to explain the present invention in more detail, the plate nori used in the present invention refers to sheet-shaped dry black-purple to green plate nori used in daily life for sushi, rice balls, and various other foods. Therefore, any conventionally known sheet nori can be used as is in the present invention, and nori in the manufacturing process before drying can also be used.

The main feature of the present invention is that a pattern such as a character, a symbol 1 figure, etc., which has high contrast and sharpness with the ground color of the sheet nori, is provided on the surface of the above-mentioned general seaweed sheet.

Conventionally, patterns have been added to the surface of sheet nori using food dyes or natural pigments, but sheet nori has a color ranging from black-purple to blackish-purple.
Since it has a green background color, even if it is printed with the food coloring mentioned above, the printed pattern and the background color will mix and the pigment will become a dark and dirty hue, giving a clear pattern. I couldn't do it. In addition, powders such as corn starch were used to give patterns such as white color, but
Since these powders have no hiding power, it was not possible to impart a pattern with high contrast.

The present invention has found that by using an ink containing a white inorganic powder with high hiding power as the ink used for patterning such plate nori, it is possible to easily form a white pattern with high contrast. This is what I did.

The ink used in the present invention is mainly composed of a white inorganic powder and a binder, and has the white i
#, a powders include calcium carbonate, calcium sulfate, calcium phosphate, barium &l oxide, titanium oxide, and other substances conventionally called white pigments or extender pigments. ! You can use anything that is in. Particularly preferred are calcium salts such as calcium carbonate, and these calcium salts are used in the food industry and medicine! ? You can use any of the ones used in Furthermore, as such calcium salts, those obtained by crushing the bones and shells of fish and shellfish and refining them as necessary are most suitable. Such calcium salts are not only non-toxic but also very useful as calcium sources.

The ink used in the present invention can be obtained by mixing and grinding the above-mentioned white inorganic powder and binder using any mixing means such as a roll mill to form a paste.

The viscosity of the resulting paste is preferably changed depending on the printing method used, and the preferred printing method in the present invention is a silk screen method.

The patterned seaweed sheet of the present invention is obtained by printing on a desired location on at least one surface of the sheet seaweed as described above using the ink as described above. The pattern to be formed may be any pattern such as letters, symbols, or figures.

(Action/Effect) The patterned seaweed plate of the present invention as described above has a sharp contrast with the background color of the seaweed plate, and the pattern is clear. In other words, in the case of conventional patterned sheets of seaweed, which were simply formed using food coloring or natural pigments, the color of the pattern was lost to the background color of the sheets of seaweed, resulting in indistinct and low contrast. On the other hand, in the present invention, since the ink contains white inorganic powder with high hiding power,
The pattern formed is not affected by the background color of the sheet nori and shows high contrast and clarity.

In addition, the patterned seaweed of the present invention, especially those using calcium salts such as calcium carbonate as white inorganic powder, are not only non-toxic to the human body but also have the advantage of being able to replenish calcium to the human body. are doing.

Next, the present invention will be explained in more detail with reference to Examples. Note that parts, parts, and percentages are based on weight unless otherwise specified.

Example The following ingredients were sufficiently kneaded in a roll mill to obtain a white ink.

) Calcium pentate 40 parts Glycerin 16 parts Locust bean gum 1 part Sorbitol
5 parts starch syrup 24
A pattern was formed on one side of a sheet of common seaweed by a silk screen method using the ink described in Part 14, followed by drying to obtain a patterned sheet of seaweed of the present invention. The pattern of this item had no shadows from the background color of the seaweed sheet, and showed an excellent contrast I/last.

Comparative Example Using red food coloring instead of calcium carbonate in Example 1, the pattern of the patterned seaweed sheet obtained in the same manner as in Example 1 exhibited a reddish-black color, and the vivid color of the red coloring agent used was No color developed.
