Description

  The present invention relates to a beverage sheet capable of simply and simply decorating the surface of a beverage.

An aesthetic appearance is an important factor in food, and decoration is performed to make the aesthetic appearance of food more beautiful. In recent years, decoration is also performed in beverages such as latte art.
As one of the methods of decorating food, there is a method of decorating using an edible sheet on which decorative characters / patterns are drawn, and various such edible sheets have been proposed.
For example, Patent Document 1 proposes a sheet printed with a edible ink on a polysaccharide sheet mainly composed of a water-soluble polysaccharide and a polyhydric alcohol as a sheet for transferring a pattern to food. ing.
Further, for example, in Patent Document 2, as a sheet for transferring characters and pictures drawn on a water-soluble edible film to the surface of food such as ice cream or ice, a plastic film and on the plastic film A water-soluble edible film having a thickness of about 1 μm to 3 μm provided with konjac glue dissolved in a liquid such as water by screen printing or a roll coater, and a picture or edible ink on the water-soluble edible film A sheet composed of a painting film depicting characters has been proposed.
Further, for example, in Patent Document 3, an edible dye layer is formed on a heat-sealable synthetic resin film as a sheet that can be brought into contact with liquid pudding and the pattern can be clearly transferred onto the surface of the solidified pudding. There has been proposed a sheet obtained by coating a water-resistant layer composed mainly of a mixture of zein and zein on the edible dye layer.
Further, for example, in Patent Document 4, by immersing a water-soluble edible sheet in which images of characters, patterns, patterns, etc. are foil-foiled, in the beverage, the edible sheet is dissolved, and the image is used as a beverage. As a edible sheet to be floated, a water-soluble and edible sheet in which a gold foil or a silver foil is pressed using a specific foil pressing material has been proposed.

The information sheet may be formed of a plurality of information sheets having different specific gravity and solubility. In this case, since the behavior of the information contained in the information sheet can be changed by the solubility, the decorativeness can be further improved. For example, an information sheet may be formed of a portion formed using ink adjusted to have a specific gravity lighter than that of a beverage and an information sheet layer formed using ink adjusted to have a specific gravity higher than that of a beverage. In this case, the part with a high specific gravity sinks into the beverage liquid after dissolution, and the light part floats on the surface of the beverage, so that the information can be converted into information by changing the retroactive information between the floating part and the sinking part. Can make changes.
In addition, a beverage sheet handling mount made of cardboard is used at the time of use, the beverage sheet is placed on the mount, the beverage sheet is transferred above the opening of the cup containing the beverage, and the mount is tilted. Thus, the beverage sheet may be put into the cup.
