Problems solved by technology

But the general edible ink that is used for ink-jet printing has the following disadvantages: 1) need supporting special ink-jet printing machine, and this printing machine is generally imported ink-jet printing machine, and is expensive; Food-grade inks use food-grade dyes dispersed in solvents, and their dispersed particle sizes generally do not reach the nanometer level; 3) There is no antibacterial effect, not only does not protect food safety, but also has adverse effects on food ;4) The quality of inkjet is not good enough

Abstract

The invention discloses a low viscosity edible antibacterial water-based ink and a preparation method thereof. The ink consists of the following components by weight percentage: 2%-8% of an edible colorant, 48%-72% of an edible solvent, 3%-9% of an edible binder and 18%-47% of an edible assistant. The preparation method includes: 1) weighing the components; 2) adding the edible assistant into the edible solvent, performing stirring to mix the edible assistant and the solvent evenly, thus obtaining a mixed solution A; 3) adding the edible binder into the mixed solution A, and conducting stirring to fully dissolve the edible binder, thus obtaining a mixed solution B; 4) adding the edible colorant into the mixed solution B, conducting stirring to fully dissolve the edible colorant, thus obtaining a mixed solution C; and 5) filtering the mixed solution C, and taking the filtrate. The ink has the advantages of low viscosity, edibility and antibacterial activity, can be directly printed on the surfaces of food and medicines, and also can be used for surface decoration of paper food packaging materials. The method has the advantages of simple process, convenient operation and low production cost.

Description

technical field [0001] The invention relates to the technical field of inkjet printing, more specifically to a low-viscosity edible antibacterial water-based ink, and also relates to a preparation method of a low-viscosity edible antibacterial water-based ink. The water-based ink can be used for printing with a general piezoelectric inkjet printing head, and the printing materials can be food, medicine, copy paper, inkjet photo printing paper, glutinous rice printing paper and other suitable paper packaging materials. Background technique [0002] Green printing is the main direction of the development of the printing industry, and the development of green printing materials has become a research hotspot in recent years. Edible packaging and printing products are a new green printing concept and a new attractive market opportunity. At present, there are few applications of edible inks in the market, mainly for printing on the surface of medicines, but less printing on other...
