Description

EDIBLE INK, A METHOD FOR ITS PREPARATION AND USE THEREOF
Field of the Invention
The present invention generally relates to edible ink, a method for its preparation and use thereof. More specifically, the present invention relates to edible ink containing a liquid medium, edible color materials, edible polyalcohols, edible monoalcohols and, optionally, edible scent and flavoring materials. The present invention further relates to a metliod for preparing edible ink comprising mixing by mechanical means edible color materials in a liquid medium; adding polyalcohols and mixing by mechanical means; adding monoalcohols and mixing by mechanical means. The said ink can be used in an ink injecting printer and may be used on edible materials.
Background of the Invention
Components of a good ink must contribute to the stability of the ink, to good dissolving of the color materials in the ink, to uniform spreading of the ink, to quick drying of the ink and to achieving clearly bordered images. Ink used in an ink injecting printer must be adjusted to the high temperatures to which it is exposed in such a printer.
In US Patent number 5,447,562 such a stable ink is achieved by applying energy to a solvent and then mixing this solvent with a liquid medium and a coloring material, thus making the bonding state of the molecules in the hquid ink of this patent, microscopically more uniform, which helps form clusters of molecules.
The present invention relates to an edible ink containing only edible solvents and color materials, in an amount that is safe for eating. In the present invention, unlike in the above mentioned US patent, the ink is produced by mixing the color materials with a liquid medium and then first mixing it with polyalcohol solvents and further mixing with monoalcohol solvents.
As will be demonstrated below, the components of the ink of the present invention and the method for its production, are most suitable for making an edible ink that can be used also in an ink injecting printer.
Summary of the invention
The present invention relates to edible ink comprising an edible liquid medium, preferably mineral free water, edible color materials, edible polyalcohols, preferably sweet, and edible monoalcohols. The ink might also contains edible flavoring and scent materials.
The edible color materials may be selected from the following: brilliant blue
FCF (Blue No 1), erithrosine (E-127, Red No 3), Red No 40, ponceau (E-
124), carmoisine (E-122), tartarazine (Yellow No 5).
The edible polyalcohols may be selected from sorbitol, mannitol, propylene glycol, glycerol, lactitol.
The edible monoalcohols are , for example, ethyl alcohol and isopropanol.
Preferably, the liquid medium is 50 - 70% of the weight of the ink, the edible color materials are 1 - 4.5% of the weight of the ink, the edible polyalcohols are 5 -20% of the weight of the ink, the edible monoalcohols are 10 -23 % of the weight of the ink and the flavoring and scent are 5 - 7% of the weight of the ink.
The present invention further relates to a method for the preparation of the said edible ink comprising mixing by mechanical means, preferably by using a magnetic stirrer, edible color materials in a liquid medium; adding polyalcohols and mixing by mechanical means; adding monoalcohols and mixing by mechanical means.
Preferably the mixing of polyalcohols with the liquid medium containing edible color materials is for a period of time slightly shorter or equal to the time of mixing the edible color materials with the liquid medium, and the mixing of the monoalcohols in to the liquid medium containing edible color materials and polyalcohols is for a period of time two or three times longer than the time of mixing the edible color materials with the liquid medium. The edible ink of the present invention can be used in an ink injecting printer and is used for writing or printing on an edible materials. The present invention also relates to food products having letters or figures with said edible ink.
Detailed description of the invention
The present invention relates to an edible ink that can be used in an ink injecting printer, and to a method for its production.
In the present invention, color material is mixed, preferably by means of a magnetic stirrer, for 5 minutes with a liquid medium. Polyalcohol solvents are then added and the hquid is mixed further for 3 - 5 minutes. Monoalcohol solvents and, optionally, flavoring and scent, are then added and the hquid is mixed for 10 -15 minutes. The hquid medium preferably used for dissolving the color materials, is distilled water, preferably 50 -70% of the weight of the ink, free of minerals which might accumulate as lime on the printer's head. The edible color materials of the present invention should not exceed 4.5% of the weight of the ink, for health reasons. These color materials may be any one of the following: brilliant blue FCF (Blue No 1), erithrosine (E-127, Red No 3) Red No 40, ponceau (E-124), carmoisine (E-122), tartazine (Yellow No 5) or any other edible color material.
The polyalcohol solvents in the present invention , such as, sorbitol, mannitol, propylene glycol, glycerol and lactitol, contribute to the sweet taste of the edible ink and they do not become caramel or turn brown in the printing conditions of the printer. Furthermore, sorbitol contributes to the color and ink stability and inhibits spreading of the ink, thus contributing to the creation of clear bordered images. These polyalcohols are preferably 5 - 20% of the weight of the ink.
The monoalcohol solvents in the present invention , such as ethanol and isopropanol, contribute to achieving the desired spreading of the ink and to its quick evaporation. Preferably, these solvents are 10 - 23% of the weight of the ink. Present in this amount, the monoalcohols contribute to a long shelf life of the ink, by inhibiting the development of mildew and bacteria, which tend to develop in liquid foods, and which may be harmful for humans. These solvents evaporate, leaving no residues, solving the problem of having a high content of alcohol in the edible ink.
Edible flavoring and scent materials may be added to the ink, preferably to 5 - 7% of the weight of the ink, to give the ink a pleasant smell and to give the printed material a smell and taste typical of sweet food. The method of the present invention produces a unique quick drying edible ink with good printing quahty on edible material, which achieves a clear and sharp image, which is stable even after the printed material comes in contact with a moist surrounding and which does not spoil.
Following is an example of an embodiment of the present invention:
0.9 gr Brilliant Blue FCF food coloring 2.47% w/w
20 gr distilled water 55% w/w
5 gr propylene glycol 13.73 % w/w 1 gr glycerol sorbitol/mannitol/lactitol 2.7% w/w
7 gr ethanol 19.2% w/w 2.5 gr scent and flavoring 6.9% w/w total 100%
