Problems solved by technology

Especially packaging materials that are in direct contact with food, such as: wrapping paper inside biscuits, seasoning packets for instant noodles, chocolate, candy, glutinous rice paper packaging and printing, etc. The inks used for these packaging and printing are basically inedible, and will Pollution to food; therefore, it cannot be directly printed on the surface of food or medicine, thus limiting the scope of use of food packaging printing inks

Embodiment 1

[0032] An edible ink is composed of the following components in mass percentage:

[0033] Gelatin 10%, Carrageenan 5%, Xanthan Gum 3%, Active Protein Powder 4%, Antifreeze Protein 2%, Food Pigment 14%, Magnesium Stearate 1%, Antioxidant Preservative 1.4%, Amorphous Dioxide Silicon 1%, food grade surfactant 0.6%, food grade ethanol 15%, water 15%, soybean oil 17%, glycerin 11%.

[0034] Its preparation method is:

[0035] First mix the mixed solvent in the container according to the above ratio, set aside 30% for ink mixing, mix the remaining 70% of the mixed solvent with other raw materials in the cylinder, and use a high-speed mixer at 800 rpm to stir and disperse for 15 minutes. Minutes, put it into a sand mill for grinding until the fineness reaches below 15 μm, then stop the grinding, add 30% solvent left over in the ink adjustment to adjust the viscosity to reach the 4# cup for 15-25 seconds, then filter and pack, that is, the obtained The product of is "Product A".

Embodiment 2

[0037] An edible ink is composed of the following components in mass percentage:

[0038] Gelatin 10%, Carrageenan 6%, Xanthan Gum 3%, Active Protein Powder 3%, Antifreeze Protein 2%, Food Pigment 14%, Magnesium Stearate 1%, Antioxidant Preservative 1.4%, Amorphous Dioxide Silicon 1%, food grade surfactant 0.6%, food grade ethanol 15%, water 15%, soybean oil 17%, glycerin 11%.

[0039] Its preparation method is identical with embodiment 1, and the product of gained is " product B ".

Embodiment 3

[0041] An edible ink is composed of the following components in mass percentage:

[0042] Gelatin 10%, Carrageenan 5%, Xanthan Gum 3%, Active Protein Powder 3%, Antifreeze Protein 3%, Food Pigment 14%, Magnesium Stearate 1%, Antioxidant Preservative 1.2%, Amorphous Dioxide Silicon 1%, food grade surfactant 0.8%, food grade ethanol 15%, water 15%, soybean oil 17%, glycerin 11%.

[0043] Its preparation method is identical with embodiment 1, and the product of gained is " product C ".

Abstract

The invention discloses an edible ink and a preparation method thereof, which is composed of the following raw materials in percentage by weight: 20%-35% of combined resin, 35%-54% of combined solvent, 8%-16% of edible pigment, and additives 1%-10%; Wherein, described combined resin is made up of gelatin, carrageenan, xanthan gum, active protein powder and antifreeze protein; Described combined solvent is made up of food-grade ethanol, water, soybean oil and glycerin; Said The auxiliary agent is composed of anti-adhesion agent, anti-oxidation preservative, anti-sedimentation agent and food-grade defoamer; this invention uses natural concentrated pigment as raw material, which is safe and non-toxic, bright in color, does not fade ink and color after repeated touch, and has good water and oil resistance , wide range of applications gravure printing, spray printing can be, good smooth performance does not block the nozzle to adapt to high-speed printing.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to an edible ink and a preparation method thereof. Background technique [0002] With the increasing awareness of people's health and safety, there are higher requirements for food and drug safety. Especially packaging materials that are in direct contact with food, such as: wrapping paper inside biscuits, seasoning packets for instant noodles, chocolate, candy, glutinous rice paper packaging and printing, etc. The inks used for these packaging and printing are basically inedible, and will Pollution to food; therefore, it cannot be directly printed on the surface of food or medicine, thus limiting the scope of use of food packaging printing inks. The ink can be used to integrate ink into food or medicine, which is an objective requirement of food and medicine in the new situation, and is the need of consumers to pursue personalized products. In addition to being able to efficiently de...
