Description

Edible Ink Composition

The present invention relates to an edible ink composition. More specifically, the present invention relates to an edible ink composition for printing an image on a candy, the edible ink composition having a suitable viscosity which is applied at a constant concentration without being easily dried on a corroded plate and can be accurately transferred to a pad.

The method of manufacturing the candy can be divided into the stamping method and the depot method according to the manufacturing equipment process. The stamping method is a method of forming a candy compound in a rope form and then molding it in a stamping machine, which is limited in making a variety of shapes of the candy. Therefore, a depot method for preparing candy by injecting a candy compound into a casting by using a depositioner and then cooling it has been widely used.

In order to increase the value of the candy produced by the depot method, it is common to print an image inside or outside the candy. At this time, since offset gravure printing, screen printing, or ink-jet printing is not suitable for printing an image on a candy in a casting, a pad is used. Printing is commonly used.

Pad printing produces several monochrome image films, depending on the image to be printed, and uses the film to primarily produce a steel plate or photopolymer plastic plate with UV or laser light. After corrosion, a dot film is placed on the image film and a fine dot shape (corrosion) of the plate is completed. At this time, in order for the ink to be filled in the corroded plate, the ink cup is moved to the engraved portion of the corroded plate so that the ink is evenly applied, the pad transfers the image of the corroded plate, and the image transferred to the pad is transferred to the surface of the product again. .

The clarity of the printing is how accurate the transfer of the ink from the corroded plate to the pad, how sharply and accurately the image transferred to the pad is transferred to the candy, and when the secondary compound is filled with the hot blend on the printed candy. It depends on whether an image can be left intact without being disturbed or blurred.

In particular, since the candy is produced at a high temperature of 140-160 ° C., the composition of the ink is an important factor in determining the printing state. Conventional inks that use alcohol or water as solvents do not spread evenly on the pads during printing, and the ink sticks to the pads when transferring the images of the corroded plate. May not be clear.

In addition, tar dyes and aluminum lake dyes are generally used as colorants used for food in order to express the color of ink. However, tar dyes usually have problems due to the water solubility of the dye solution and the vividness of printing. Aluminum lake type food coloring is used. However, the aluminum lake type pigments are easily dried on the corroded plate, and as the printing is repeated, the transfer state to the pad is gradually worsened, and when the high temperature compound is injected onto the printed image, the color is not maintained and spreads. .

In view of the characteristics of the candy manufacturing process, the inventors have developed an edible ink composition having an appropriate viscosity that is not easily dried on a corroded plate but is applied at a constant concentration to be accurately transferred to a pad even when using an edible ink for a long time. The ink composition of the present invention can accurately and clearly print the image on the pad to the candy, and even if a high-temperature compound of 140-160 degrees is injected after printing the image on the candy, color bleeding, fade, etc. do not occur and color is uniform. And keep it sharp.

In addition, the present invention proposes an optimal process condition for printing a desired image on the candy using the edible ink composition.

The above and other objects of the present invention can be achieved by the present invention described below.

The present invention is 10-30 parts by weight of fermented alcohol, 15-30 parts by weight of a mixed solvent consisting of propylene glycol, glycerin, and water, 5-10 parts by weight of shellac, 15-35 parts by weight of D-sorbitol and 1-15 parts by weight of food coloring. Regarding an edible ink composition, the edible ink composition may further include an additive selected from the group consisting of natural rubber materials, maltodextrin, sugar, and glycerin fatty acid ester, in addition to the basic components.

In a preferred embodiment of the present invention, the edible ink composition is 10-35 parts by weight of fermented alcohol; 15-30 parts by weight of a mixed solvent (I) consisting of propylene glycol, glycerin, and water; 5-10 parts by weight of a mixture of shellac and maltodextrin (II); 15-35 parts by weight of a mixture of sugar and D-sorbitol solution (III); 2-10 parts by weight of natural rubber material; 3-8 parts by weight of glycerin fatty acid ester; And 1-15 parts by weight of food coloring.

Each ratio and content herein is by weight unless otherwise indicated. Hereinafter, each component of the invention will be described in detail.

Fermented alcohol is ethanol for food addition and is used as a main solvent of conventional edible ink. In the present invention, instead of lowering the ratio of the fermentation alcohol, a mixed solvent (I) consisting of propylene glycol, glycerin, and water is used. At this time, propylene glycol, glycerin, and water are preferably mixed in a weight ratio of 1-10: 85-95: 40-60. The composition of the mixture is determined in consideration of the specificity of the candy printing process in which the evaporation speed of the ink solvent is high because the surface temperature of the object to be printed is relatively high, and the mixed solvent in the range outside the above ratio is too fast or too slow to evaporate the solvent. Images cannot be printed clearly.

Shellac and maltodextrin are used to improve the spreadability of the ink during printing and to keep the printed ink stable so as not to spread. Only shellac may be used, but it is preferable to use mixture (II) in which shellac and maltodextrin are mixed in a weight ratio of 2-10: 1-5. If the ratio is out of the ink, the ink may bleed and the image may not be printed clearly.

Sugar and D-sorbitol liquid are used to soften the viscosity of the ink and to improve printability. It is preferable to use the mixture (III) which mixed sugar and the D-sorbitol liquid at the weight ratio of 4-8: 2-4. If the ratio is out of the ratio, the viscosity of the ink is too high or low so that the image cannot be printed clearly. D-sorbitol solution is prepared in a liquid phase by reacting glucose with a nickel catalyst under high temperature (120 ° C.) and high pressure (100 kg / cm 2) according to a method known to those skilled in the art, and then removing the catalyst.

Glycerin fatty acid ester is used in order to improve the emulsification property of an ink composition. When the glycerin fatty acid ester is used in less than 3 parts by weight, the ink composition is not emulsified well, and when the glycerin fatty acid ester is more than 8 parts by weight, it is not economical because it does not contribute to increase the emulsification.

Natural rubbery materials are used to ensure that the ink is transferred to the pads clearly and precisely so that an accurate and clear image can be transferred onto the candy and that the ink color remains unchanged even at high temperature formulations of 140-160 ° C. . In the present invention, it is most preferable to use a mixture of gum arabic, carrageenan, guar gum and xanthan gum as a natural rubber material, and the mixing ratio of gum arabic (and / or carrageenan), guar gum and xanthan gum is 3-6: 2. -4: 1-2 weight ratio is preferable. The color of the ink is easily changed when out of the weight ratio. In this case, the gum arabic and carrageenan may be used in a 1: 1 weight ratio, or the gum arabic or carrageenan may be used alone. Conventional edible ink may also be used, such as locust bean gum, gellan gum, Karayan gum, tara gum, gatti gum, etc., but when such gums are used, the viscosity of the ink is high and the movement of the ink cup is not smooth, and the printing state is not preferable.

Food coloring

In the present invention, tar dyes are used instead of general aluminum lake dyes, and basic dyes for 4th printing are as follows.

Blue pigment is used by mixing food coloring blue No. 1 (or blue No. 2) and titanium dioxide in a weight ratio of 10-20: 1-2, and 2-13 parts by weight.

The red pigment is mixed with food coloring red No. 40 (or red No. 3 or red No. 2) and titanium dioxide in a weight ratio of 8-16: 2-4, and 2-15 parts by weight is used.

Yellow pigment is mixed with food coloring No. 4 No. 4 and titanium dioxide in the weight ratio of 3-6: 1-3, 1-10 parts by weight is used.

Black pigment is food coloring blue No. 1 (or blue No. 2), red No. 40 (or red No. 3 or red No. 2), yellow No. 2-4: 3-7: 4-8 It is mixed by the weight ratio of 5-15 parts by weight.

Printing process

A specific process for printing an image on a candy is disclosed in detail in Korean Patent Application No. 2001-7587, the applicant's prior application.

This is summarized as follows:

The primary blend prepared by dissolving and concentrating the raw material for preparing candy is poured into the primary mold while maintaining the temperature of 130 to 150 ° C, and the primary blend is cooled to have a surface temperature of 30 to 45 ° C (when cooling). Air conditioning conditions: temperature 15-25 DEG C, relative humidity 35-65%); Printing the desired image on the formulation using pad printing at 4 degrees in the order of black, yellow, red, and blue edible ink (indoor air conditioning conditions: 20 to 35 ° C., relative humidity 35 to 65%); In addition, the secondary formulation prepared by dissolving and concentrating the raw material for preparing candy in the photo-printed formulation was re-injected while maintaining the temperature of 120 to 135 ° C to be secondarily cooled (air-conditioning condition during cooling: temperature of 15 to 25 ° C, relative Humidity 35-65%) Candy with the image printed.

When printing in the above manner, in order to smoothly reciprocate the ink cup on the corrugated plate during pad printing, the temperature of the corroded plate and the ink cup should be matched to 20-35 ℃, but the temperature of the corrugated plate and the ink cup is different. The ink cup does not slide smoothly on the corroded plate, resulting in uneven printing on the pad. In addition, the room humidity should be maintained at 35-65% during the candy process to prevent the ink from drying easily. If the above temperature and humidity conditions do not meet, there is a problem that the ink of the corroded plate is dried too quickly, so that the pad does not transfer 100% of the corroded portion of the corroded plate, and when the ink is dried too slowly, the corroded plate Transfer from the pad to the pad is good, but there is a problem that the ink is smeared when a high-temperature formulation of 140-160 ℃ on the printed candy.

The invention can be better understood by the following examples, which are intended to illustrate the invention and are not intended to limit the scope of protection defined by the appended claims.

Example 1

Sugar, starch syrup and water were added to the dissolution tank to dissolve it. The dissolved raw material was transferred to a vacuum concentration tank and concentrated at 145 ° C. under 200 mm Hg until a constant viscosity was obtained. The concentrated formulations were mixed in a mixer by means of a transfer pump together with additives for the production of flavors, pigments and the like, and then injected into the primary depot. The compound was injected from the primary depositor while the mold was moved by the conveyor mold feeder. The mold in which the compound was injected was cooled through the primary cooling tunnel so that the compound surface temperature was 30 to 45 ° C.

The cooled primary formulation is passed through a pad printing machine equipped with a corroded plate by a transfer device, where the desired image is printed 4 degrees using the blue, red, yellow, and black edible ink compositions according to the invention. It became.

The composition of the ink composition according to the present invention is as follows.

Parts by weight; 10 parts by weight of a mixture (II) of shellac (manufactured by The Japan Shellac Industries, Ltd.) and maltodextrin (target product); 20 parts by weight of a mixture of sugar (Korean sugar) and D-sorbitol solution (III); 5 parts by weight of glycerin fatty acid ester (ILSIN Monocopper ES-95); And it was prepared by mixing 10 parts by weight of food coloring.

The blue pigment was mixed with food coloring No. 1 blue and titanium dioxide in a weight ratio of 10: 1, the red pigment was mixed with food coloring red No. 40 and titanium dioxide in a ratio of 4: 1, and the yellow pigment was food coloring yellow. No. 4 and titanium dioxide were mixed at a ratio of 3: 1, and black pigment was prepared by mixing food coloring blue No. 1, red No. 40, and yellow No. 4 at a ratio of 2: 3: 4.

Among the components, titanium dioxide is manufactured by Kronos, red No. 3 is erythrosine, blue No. 1 is FD & C Blue No. 1, yellow No. 4 is FD & C Yellow No. 5, and red No. 40 is FD & C Red No. 40 standard was used.

After printing is completed, the candy preparation formulation and additives are secondaryly injected onto the mold in a secondary depositor. The components and contents of the second infused formulation were the same as in the first injected formulation. The temperature of the blend fed to the mold was 135 ° C. The secondary blend was formulated, dissolved and concentrated in the same way as the primary blend. Upon completion of the formulation feed, the mixture was finally passed through a second cooling tunnel, cooled, and then separated from the mold to obtain a candy with the desired image.
