Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an edible ink and a method for producing the same, and more particularly to the ink having a yellow color.

[0002]

2. Description of the Related Art The applicant of the present application forms a predetermined pattern by screen printing with a lipophilic edible ink on a smooth plate surface, and places a chocolate material in a sink arranged around the pattern forming position. We are implementing a method of manufacturing patterned chocolate confections that can be poured
1-50376).

According to such a manufacturing method, it is possible to perform a multi-color printing on the chocolate surface by using an inexpensive edible ink, regardless of the kind of the constituent material of the plate surface, which is a useful action and effect. . The above-mentioned manufacturing method can be applied not only to white chocolate but also to ordinary chocolate that has a dark brown color, and as the color of the edible ink used at this time, yellow that is clearly visible against the dark brown color is often used, for example, the Ministry of Health and Welfare. An edible ink is used in which titanium dioxide as a color-developing agent is mixed with the approved synthetic colorants Yellow No. 2 and Yellow No. 4, etc.

[0004]

By the way, in recent years, there has been a tendency to refrain from using titanium dioxide and synthetic coloring agents as exemplified above, and it has been attempted to provide a product containing a natural dye in the edible ink. ing.

However, in the case of edible inks having a relatively thick shade, even if a natural pigment is added, a clear image appears on the chocolate, but it can be formed especially with an edible ink which exhibits a yellow color due to a natural pigment such as gardenia yellow. In addition, the transparency of the pattern was too high, and the color of the underlying chocolate was transparent and visually recognizable. Not only was it unclear, but the appearance was also significantly impaired.

If the above natural pigment material is blended in an excessive amount in order to avoid such a situation, the blending amount of the vehicle becomes relatively insufficient, and the compatibility with the underlying chocolate material becomes poor.

The present invention has been proposed in view of the above-mentioned conventional circumstances, and is an oily natural dye exhibiting a yellow color that can surely conceal a base and form a pattern that can be clearly recognized on the base. It is an object to provide an edible ink containing a material and a method for producing the same.

[0008]

In order to achieve the above-mentioned object, in the present invention, an oily natural pigment material 10 which exhibits a yellow color is used.
An edible ink comprising 15% by weight, 15 to 40% by weight of edible oil and fat as a vehicle, and 50 to 70% by weight of eggshell calcium is used.

The above-mentioned edible oil / fat preferably has a melting point of 30 to 45 ° C., and it is also possible to add vegetable oil / fat as a viscosity modifier in an amount of 3 to 5% by weight. In order to produce such an edible ink, an edible oil / fat serving as a vehicle is heated to a temperature equal to or higher than the melting point, and an oily natural pigment material exhibiting a yellow color and egg shell calcium are added and agitated in the above-mentioned composition.

[0010]

In the above structure, the eggshell calcium is blended in a relatively large amount, and the surface of the eggshell calcium is colored with the oily natural pigment material, so that the transparency of the formed pattern is lowered. There is. In addition, this egg shell calcium has a white color, and the color development by the above natural pigment does not become unclear.

The edible oil and fat as a vehicle may be any product commonly used in confectionery production, and is not particularly limited, but considering the handling in the production process and printing process of the edible ink, the melting point of the base chocolate. It is desirable to set the melting point to about 30 to 40 ° C., since it is desirable to set the temperature to a temperature slightly higher than that and as low as possible.

Further, it is desirable that the above-mentioned egg shell calcium is blended in an amount of 50 to 70% by weight based on the whole edible ink and is blended in a large amount as much as possible in order to obtain a good finish. Has an abnormally high viscosity, which causes difficulty in handling such as screen clogging during subsequent printing. Therefore, in order to adjust the viscosity of the edible ink, edible oil or fat may be added as a viscosity adjusting agent when kneading the edible ink.

In order to produce the above edible ink, the edible oil / fat serving as a vehicle is first heated above its melting point, and then a material such as an oily natural pigment material or egg shell calcium is added. The amount of the above-mentioned edible oil / fat is preferably 15 to 40% by weight, and if it is less than this range, the viscosity increases, clogging occurs at the screen printing in the latter stage, and the compatibility with the underlying chocolate becomes poor. On the other hand, when the amount of the edible oil and fat is large, the fluidity of the edible ink becomes too high and the pattern is not bulged and the pattern cannot be clearly recognized.

The above-mentioned oily natural coloring material is not particularly limited as long as it exhibits a yellow color, and a product obtained by subjecting gardenia yellow to a lipophilic treatment with glycerin fatty acid ester or edible oil and fat (see JP-A-53-29965). Is used, and the compounding amount is in the range of 10 to 15% by weight. If the blending amount is smaller than this, the color development is insufficient, and conversely, if it is too large, the blending amount of egg shell calcium becomes relatively small and the desired effect cannot be obtained.

[0015]

EXAMPLE As shown in Table 1 below, first, an amount of edible oil / fat corresponding to 28.5% by weight of the whole edible ink to be produced is melted by boiling. This edible oil / fat has a melting point of about 35 ° C., which is slightly higher than the melting point of chocolate and is as low as possible.

Then, 11.3% by weight of the oily natural pigment material and 61.2% by weight of egg shell calcium are put into a container-melted edible oil and fat. These ingredients are very compatible with edible oils and fats and evenly stirred, and evenly diffused throughout.

In this example, since the amount of the egg shell calcium was slightly large, the viscosity of the edible ink after kneading was high, and there was a risk of clogging during screen printing in the subsequent stage. 3% by weight of edible oil and fat was added.

The edible ink thus obtained can form a fine pattern on the chocolate surface in the same manner as in the past. That is, screen printing is performed on the surface of a flat plate material made of silicon rubber by using a screen plate on which a required pattern is made. In addition, the mesh size of the screen plate used at this time is about 100 to 150 mesh, which is coarser than that of the screen plate (usually 200 mesh or more) used in the conventional method, and the thickness of the pattern is slightly increased. At the same time, we are trying to prevent clogging.

Further, a mold is placed around the flat plate material made of silicon rubber on which the above pattern formation is completed, and the melted chocolate is poured and cooled and solidified, and then the mold is removed to complete the product.

As described above, according to the embodiments of the present invention, the surface of eggshell calcium mixed in a relatively large amount in the edible ink is colored with a natural pigment, and the colored eggshell calcium is used as a base. Since the chocolate was hidden, the color of the chocolate was not visually recognized through the pattern, and a clear yellow pattern was visually recognized.

The present invention is not limited to the above-mentioned embodiment, but the composition of each constituent material and the concrete product may be appropriately tested to determine the optimum composition.

[0022]

[Table 1]

[0023]

As described above, according to the present invention, the pattern formed by the edible ink using the yellow natural pigment almost completely conceals the ground color (brown color) of chocolate and can be visually recognized in a clear contrast, The color will be visually recognized to the same extent as the conventional synthetic colorant.
