Description

  The present invention relates to a method for printing on food, and in particular, with respect to a processed food having a smooth outer surface and moisture and oil, printing is directly performed on the outer surface of the food with edible ink. Regarding the method.

  Recently, it has been proposed that characters, symbols, illustrations and patterns according to photos and tastes are displayed on the surface of foods such as chocolate and cake using edible ink. Printed information display contents such as desired photos, characters, etc. on edible film with ink, and the edible film is structured to be polymerized and fixed on the surface of food with the printed surface outward, and various presents And used for events.

However, the above-mentioned fixing method for printed contents is difficult to adapt to foods with wet outer surfaces, especially processed foods, such as tofu, konjac, stripped eggs, and edible films. It was.

  The problem to be solved by the present invention is that the conventional method of displaying the printed content on the surface of food cannot be applied to food with wet surfaces, and a method such as direct stamping is used. However, the softness and curved surface of food could not be dealt with sufficiently, and the printing result in a beautiful finish could not be obtained.

In order to solve such a problem, the method for printing on food according to the present invention is a starch in which an information content display is printed with edible ink on the outer surface of a food body as a base having a smooth outer surface. Collagen, gelatin, wafer, starch syrup, corn, sugar, edible film as a material selected from the polyester materials approved by the Food Sanitation Act To the food that leaves only the printed portion of the information content by melting and removing the edible film with the moisture or oil present on the outer surface of the food body over time and soaking it in the outer surface of the base food body in the method of printing, the edible film has a thickness of about 0.1 mm, the printing portion of the information content is protruded in a thickness of about 2μm on one surface of the edible film, the printed portion Buried on the outer surface of the food body to be over scan, with its fixed stacked state, the time of the molten removal is characterized in that 10 to 15 seconds.

In the food printing method according to the present invention, the edible ink is an ultraviolet curable ink .

  The method for printing on food according to the present invention is configured as described above. Therefore, the information content printed with the edible ink can be finely expressed with respect to the food whose outer surface is wet. This method takes advantage of the characteristics of the edible film on which edible ink is printed, and only melts and removes the edible film. It is possible to execute the desired photos, characters, etc. on the eggs, etc. with tofu and stripped salmon that did not exist conventionally, and greatly improve the added value of the product This will satisfy the taste of the consumer.

  This was realized by configuring as shown in the drawings and described in the examples.

  Next, an example of a preferred embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a state in which printing is completed with a base food as tofu, FIG. 2 is an enlarged cross-sectional view of the main part, and FIG. 3 is a partial front view showing the process.

  In these figures, 1 indicates tofu serving as a base food. This tofu 1 is usually formed in a rectangular parallelepiped shape, and print indications 2 and 2 are displayed on at least one surface thereof. In this embodiment, a ring diagram with a striped pattern is simply shown, but this is only an example, and there is no problem with photographs, letters, messages, and other symbols and patterns. Can be adopted.

Initially, the printed displays 2 and 2 are directly formed on one surface of the edible film 3 as a printed layer with a thickness of about 2 μm . Here, the print indications 2 and 2 are formed by edible ink. In this embodiment, ultraviolet curable ink is used as the edible ink.

  Moreover, the edible film 3 used in the present embodiment has a flat shape, and has a thickness of about 0.1 mm. In addition to the polyester film approved by the Food Sanitation Law, any material of starch, collagen, gelatin, oblate, starch syrup, corn, sugar, etc. can be selected and used according to the target food. The

  The edible film 3 having the printed indications 2 and 2 formed on the one side is polymerized and laminated with the printed indications 2 and 2 in contact with any one side of the tofu 1 which is the base food in this embodiment. The That is, polymerization lamination is performed with the back side of the edible film 3 as the outside.

  If this polymerization lamination state is left as it is for 10 to 15 seconds, the moisture present on the outer surface of the tofu 1 acts to melt the edible film 3 leaving only the printed displays 2 and 2. The portions of the print indications 2 and 2 soak into the outer surface of the tofu 1, and the print indications 2 and 2 are exposed on the outer surface of the tofu 1.

  Here, when the water and oil content in the base food is insufficient, the edible film 3 is sufficiently melted when the water washing operation is performed for several seconds in the above-described polymerization state, and the same result as described above is obtained. Can do.

  This printing method should be performed not only on the normal rectangular tofu 1 but also on a curved surface such as a dome-shaped tofu or stripped boiled egg using the flexibility of the edible film 3 itself. The printed displays 2 and 2 are held for a long time until they become clear and served.

  The printing method for foods according to the present invention can be sufficiently applied to tofu and boiled eggs as examples, kneaded products such as konjac, hanpen, and salmon, and deep-fried foods such as sweet potatoes. In addition, it can be applied to fish fillets, vegetables, fruit fresh foods and lunch boxes.

  Furthermore, the edible film 3 itself used in the present invention can be traded as a product in a state in which the print indications 2 and 2 are enforced, and is executed not only at a food processing company but also at a personal level. It can also be used for your own events and fun.

It is a perspective view which shows the state by which printing was completed by making the foodstuff used as a base into tofu. It is a principal part expanded sectional view. It is a partial front view which shows a process.

Claims (2)

Approved by the Food Sanitation Act for starch, collagen, gelatin, oblate, starch syrup, corn, sugar, and other foods that have a smooth outer surface printed with edible ink on the outer surface. The selected edible film is selected from the polyester materials, and the printing surface is contacted and fixed and laminated, and then the edible film is moisture or oil present on the outer surface of the food body. In the method of printing on foods, which is melted and removed over time and soaked into the outer surface of the base food body to leave only the printed portion of the information content, the edible film has a thickness of about 0.1 mm. and the printed portion of the information content is protruded on one surface of the edible film with a thickness of about 2 [mu] m, buried on the outer surface of the food body comprising the printing portion based, at its fixed stacked, the Printing method to food, wherein the time of the fusion removal of 10 to 15 seconds.   The method for printing on food according to claim 1, wherein the edible ink is an ultraviolet curable ink.
