Embodiment 1

[0033] Embodiment 1: the preparation method of edible red ink is as follows:

[0034] (a) Protoplasm preparation method: earlier with 60% (weight) fructose, 15% (weight) 1,2 propylene glycol; 1% (weight) beeswax, 2% (weight) sodium alginate, 5% (weight) arabic acid Pour the gum and 10% (weight) deionized water into the container and stir evenly, then pour it into a high-speed magnetic heating stirrer, adjust the temperature to 45°C, stir for about 15 minutes, then place it for 15 minutes, and cool to normal temperature .

[0035] (b) Add 5% (weight) edible monascus red pigment into the original slurry and stir for about 30 minutes, then add 2% (weight) shellac edible solution and stir for another 10 minutes. An edible ink for screen printing with an ink particle diameter less than 80 μm is obtained by using an ink filter.

Embodiment 2

[0036] Embodiment 2: the preparation method of edible gardenia yellow pigment ink is as follows:

[0037] (a) Protoplasm preparation method: earlier 25% (weight) oligofructose, 25% (weight) isomaltulose, 10% (weight) 1,2 propanediol 10% (weight) n-propanol, 1% (weight) ) stearic acid, 1% (weight) palmitic acid, 2% (weight) sodium alginate, 1% (weight) bean gum, 1% (weight) guar gum, 1% (weight) gum arabic, and 16 % (weight) deionized water is poured into a container and stirred evenly, then poured into a high-speed magnetic heating stirrer, the temperature is adjusted to 50°C, stirred for about 20 minutes, left for another 20 minutes, and cooled to normal temperature.

[0038] (b) Add 4% (weight) edible gardenia yellow pigment into the protoste and stir evenly for about 30 minutes, then add 3% shellac alcohol solution and stir for another 10 minutes. An edible ink for screen printing with an ink particle diameter less than 80 μm is obtained by using an ink filter.

Embodiment 3

[0039] Embodiment 3: the preparation method of edible capsanthin ink is as follows:

[0040] Protoplasm preparation method: earlier 50% (weight) starch sugar, 15% (weight) n-propanol, 1% (weight) polyhydric alcohol, 2% (weight) sodium alginate, and 14% deionized water are poured into container After stirring evenly in the medium, pour it into a high-speed magnetic heating stirrer, adjust the temperature to 45°C, stir for about 15 minutes, and let it stand for another 15 minutes, and cool to normal temperature.

[0041] (b) 8% (weight) edible capsanthin was added in the protoste and stirred evenly for about 30 minutes, then 8% (weight) shellac alcohol solution was added and stirred for another 10 minutes. An edible ink for screen printing with an ink particle diameter less than 80 μm is obtained by using an ink filter.

Abstract

The invention provides edible ink for screen printing and a preparation method thereof. The edible ink comprises the following components in percentage by weight: 45-65 percent of binder, 15-25 percent of solvent, 1-3 percent of plasticizer, 1-5 percent of emulsifier, 1-5 percent of stabilizer, 10-40 percent of deionized water, 3-10 percent of food colorants and 2-10 percent of lac edible solution. By adoption of the technical scheme, a screen printing process can be adopted, only a thin layer is formed on the surface of foods, medicines and other printed materials, the moisture content of the dried ink is low, mildew can be effectively avoided, and the quality guarantee period is prolonged. Meanwhile, the method for preparing the edible ink is simple, and the ink is low in price, has the characteristics of high liquidity, low viscosity and fast dry property and has excellent commercial application prospects.

Description

technical field [0001] The invention belongs to the technical field of printing ink, relates to an edible ink and a preparation method thereof, in particular to an edible ink which can be used for screen printing and a preparation method thereof.
