Abstract

PURPOSE:To permit a multi-color printing on foods without damaging the commercial value of foods by a method in which an edible ink is printed on the surface of a food and then an edible powder is spread over the printed surface before the ink is dried. CONSTITUTION:On the surface of a food base, e.g., biscuit, chewing gum, etc., a desired pattern is printed by using an edible ink composed of an edible dye and an edible binder, e.g., edible solid fats or oils, etc., and before the edible ink is dried or absorbed by the food base, an adible powder, e.g., alipha-starch, wheat flour, sugar, etc., is spread over the printed surface by using a screen or brush, etc. After removing excess powder, a printing is further made on the printed surface by using another edible ink of a different color. Thus, since the powder is spread, the migration of the previous ink to the next printing screen plate can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of printing on food surfaces using edible inks.

In the past, in the food field, in order to give food freshness and beauty, simple patterns were formed on the surface of foods using a branding iron 1ζ, or food coloring was added.However, in recent years, dietary habits have diversified. As a result, food products with more complex patterns and colorful colors have come to be preferred, and one way to achieve this is to print on the surface of food products.

Stamp printing and screen printing are the main methods of printing on food surfaces due to the ease of equipment, but screen printing is the most suitable method for printing complex patterns.

Edible screen printing inks are conventionally known in water-based, oil-based, and engineered mulch type. In the case of color printing 1. If one tries to apply the usual printing method, that is, a series of steps of drying the printing ink after printing and then printing with a second printing ink.

It is understood that the heat during drying causes deterioration and deformation of the food, which seriously reduces the product value.

Next, drying that does not rely on heat 1ζ was considered, but in this case, the production speed was severely limited and the production cost was high.In order to remove the grain spots, for example, ethanol was added to the water-based ink to speed up the drying process. When trying to speed up the process, a new problem arose: the screen version was cut off.

In view of the above-mentioned problems, the inventors of the present invention have developed a method in which the printing ink of the printed image area that is first printed on the surface of the substrate is used in multicolor printing using the screen printing method. The present invention was arrived at while considering the process of converting the next plate to a screen plate. A desired pattern is printed on the surface using edible ink, and before the edible ink dries or is absorbed by the substrate, edible powder is sprinkled on the surface of the printing target and adheres to the printed image area. This invention relates to a printing method that eliminates mold by setting the paper. The second invention is l
Alternatively, a multicolor printing method comprising a plurality of printing steps selected from two or more of the above steps S and a step of printing rice with an edible ink exhibiting a color different from the above is dissolved or dispersed in water IC. Water-based ink that has a viscosity that is suitable for printing by adding a thickener or edible resin, oil-based ink that has food coloring dissolved or dispersed in food oil with a viscosity suitable for printing, and food coloring. There are industrial inks made by emulsifying edible oil, fat, and water using an edible emulsifier.

As a method for printing the above-mentioned edible ink on the surface of the edible substrate, other printing methods such as a flexo printing method and an offset printing method may be used in addition to the screen printing method.

The food coloring used in the edible ink can be appropriately selected from conventionally known synthetic food colorings and natural food colorings. As a coloring matter for Zengcheng★, for example, food red color 9
Food Red No. 3 0 Food Yellow No. 4 1 Food Yellow No. 5 1 Food Green No. 3 0 Food Color Growing No. 1 0 Food Blue No. 2 and these
Examples include dyes that have been made into a mulch. Examples of natural food colorings include caramel color, gardenia color, monascus color, annatto color, beetroot color, anthocyanino color, publica color, cochineal color, copper chlorophyll and its sodium salt.

Solid edible fats and oils are also used as binder components for edible inks.
Alternatively, water-soluble polymeric substances such as gum arabic, sodium salt of carboxymethylcellulose, methylcellulose, and sodium alginate may be added.

The edible powder in the present invention includes pregelatinized starch, wheat flour starch, wheat flour, powdery thickeners such as coystana and dextrino, *sugar alcohols of sorbitol, manji, and tonato.

glucose, sucrose. Sugars such as lactose, gelatin.

Proteins such as albumin, vegetable or microbial polysaccharide powder, natural gums such as gum arabic, and carboxymethylcellulose sodium salt.

Methylcellulose, sodium alginate, propylene glycol alginate, calcium cellulose glycolate, sodium cellulose glycolate, sodium starch phosphate, sodium polyacrylate,
Edible polymer substance powder such as crystalline cellulose 0 salt, calcium carbonate, sulfur m calcium! It is also possible to use food material powders such as inorganic powders such as 1), 1) powder, f-su powder, and edible waxes.

Furthermore, it is also possible to use the above-mentioned edible powder that has been previously colored with an edible coloring agent to color the printing area along with the setting of printing ink.

The particle size of the edible powder does not need to be limited to gram, and not only powder but also granule may be used as long as it can achieve the purpose of the present invention, but preferably 60 mesh or more. The body is used.

To spread edible powder after printing on the surface of an edible substrate, there are methods such as spreading by vibrating the powder on a sieve and using a brush, but of course it is also possible to spread by hand. It may also be dispersed by spraying.

After scattering the edible powder, it is preferable for the next process to remove unnecessary powder from the edible substrate, and various methods can be considered for this purpose, such as a method of suctioning with air, a method of blowing air, etc. There are methods such as applying it to the surface and sweeping it off with a spatula.

Examples of applicable foods related to the present invention include biscuits, RiV
Keys, crackers and chewing gum.
