JPS6072784A - Printing of candy and chewing gum - Google Patents

Abstract

PURPOSE:To keep pattern, mark, etc., printed on the surface candy and chewing gum stable by a method in which the surface of a candy or chewing gum is covered with a resin layer composed of shellac or a mixture of shellac and a rosin as main component, and printing is made on the surface. CONSTITUTION:A 50wt% or less alcohol solution of purified white shellac or a mixture of purified shellac and purified rosin in an amount of less than half of the purified shellac is sprayed or coated on the surface of a candy or chewing gum and allowed to stand in the air or under reduced pressure to form a transparent and colorless resin covering layer on the surface of the candy or chewing gum due to the vaporization of the alcohol solvent. Printing of letter, pattern, mark, etc., is made on the surface of the candy or chewing gum by using an edible ink.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to confectionery, and an object of the present invention is to stably retain printed patterns, symbols, etc. on the surface of candy or chewing gum.

BACKGROUND ART Candies, chewing gum, etc. that have patterns, symbols, etc. printed on their surfaces tend to be preferred by consumers because of their palatability. However, such materials lack stability due to changes in environmental conditions such as temperature, humidity, etc., resulting in drawbacks such as loss of stability, shearing, and disappearance over time. In other words, if the humidity and temperature are high, the pattern will gradually disappear.

The present invention is free from such drawbacks.

This invention will be explained in detail below.

The term "candy" used in this invention is a general term for candy made by boiling down sugar, such as bonbons, drops, caramel, nougat, and others. Actually, chewing gum is a solid product made by adding sugar and other substances to tree sap chicle and vinyl resin.

First, a specific thin resin layer is formed on the surface of candy or chewing gum. This is a feature of this invention.

A specific resin is employed to form a specific resin layer.

It refers to refined white shellac or refined shellac mixed with less than half the amount of refined rosin. Make an alcohol/v bath solution of 50% (by weight, same below) or less. This solution is sprayed or smeared onto the surface of candy or chewing gum. This product is left in the atmosphere or under reduced pressure. In this way, the solvent alcohol escapes into the atmosphere, and the resin layer obtained from the alcohol bath of candy or chew-in refined shellac, or its mixture with purified rosin, is transparent and colorless. Pattern symbols printed during the process can be clearly observed from the outside. Furthermore, since the shellac layer is inherently heat resistant, moisture resistant, and corrosion resistant, the pattern of the target candy or chewing gum obtained after the next printing process is resistant to changes in temperature, humidity, and friction in the environment. It becomes stable.

Print characters, figures, symbols, patterns, etc. on its surface.

The printing method may be tacho printing, gravure printing, Nuclean printing, or any other method. The ink used at this time may be any edible ink, for example, it may be oil-based, alcohol-based or water-based.

The resin layer or the rosin-mixed resin layer mainly made of shellac is printable and has good ink adsorption properties, so the pattern etc. of the target product is stable.

Furthermore, when the surface of the object obtained in the first invention is coated with a shellac resin layer, more stable printed candy and chewing gum can be obtained. The method of forming the resin layer is the same as that for the first concentration.

Here, this invention achieves its purpose. Hereinafter, this invention will be explained in more detail with reference to Examples.

Example 1 30% (30%) of purified white shellac was applied to the surface of chewing gum.
Weight, same below) Ethyl alcohol solution was applied and dried with air. Octopus printing was performed on this surface using water-based red ink to obtain clear photographs.

Chewy without surface treatment with shellac liquid (°C 1 room with humidity 60-80% 1). There were no abnormalities on the surface treated side.

Example 2 Candy (201 parts starch syrup, 80 parts sugar, 14 parts water 10V)
An ethyl alcohol solution containing 30% purified white shellac and 5% purified rosin was sprayed onto the surface of the sample (boiled down to 5°C, cooled and solidified), and dried under reduced pressure. Lines were screen printed on the surface of this object using water-based chocolate colored ink. Clear printing was possible.

Similar printing was carried out on the surface of candy which had not been subjected to any other surface treatment with shellac liquid. Room temperature 24-30°C, humidity 6
Both were left standing in a room with a room temperature of 0 to 80% for 3 days.

In the case where no surface treatment was applied, the imaged areas were dissolved after 3 days.

There was no abnormality at all on the surface treated side.

-5 = Example 8 The shellac liquid shown in Table 1 was applied to the surface of a candy made of the same material as in Example 2 and air-dried indoors.

On this surface, the symbols ``a'', ``mouth'', ``ha'', and ``2'' were printed using alcoholic blue ink using the gravure method.

Clear printing was possible. The shellac liquid shown in Table 1 was sprayed onto the surface of this product, and the product was air-dried indoors. This material did not peel off even when rubbed with wet fingers.

Table 1 Example 4 The shellac liquid shown in Table 2 was applied to the surface of chewing gum, and after air drying, screen printing was performed using oil-based yellow ink. I was able to print clear lines of a doll pattern. The rack solution shown in Table 3 was sprayed onto this surface and air-dried indoors. I rubbed this stuff with my damp fingers and it didn't flake off. It was also stored at 35°C for 1 month, but there was no loss of print or misalignment at all.
