Problems solved by technology

However, since such inks contain water-soluble pigments and binders, they have poor water resistance and cannot be used for items in contact with water.
In addition, due to the poor coverage of water-soluble pigments, this ink cannot be used on dark items

Abstract

The invention provides a preparation method and application method of edible ink for inkjet printing. This ink can form printed records with good identification and certain water resistance on the surface of various foods (including tablets), food contact materials, food packaging materials, etc. The raw materials of this inkjet ink are approved food additives, including shellac, cellulose resin, ethanol, water and so on. The manufacture method of this ink-jet ink is: a, food coloring is dispersed or dissolved in the aqueous solution that contains cellulose resin to make color base dispersion, contains the water more than 50wt% in this dispersion; B, shellac Dissolve in dehydrated alcohol and make shellac solution, contain the dehydrated alcohol more than 50wt% in this shellac solution; c, color paste dispersion is dispersed in shellac solution again, add a certain amount of conductive salt sodium lactate, pH Regulator ammonium carbonate, humectant, emulsifier, defoamer, etc.; d, filter filling.

Description

technical field [0001] The present invention provides a method for producing an edible ink for inkjet printing and its use for forming printed records with good visibility and certain water resistance on the surface of food (including tablets), food contact materials, food packaging materials, etc. method. Background technique [0002] Ink has always played an irreplaceable role in the printing and packaging industries. The rich and colorful colors it presents not only beautify people's lives, but also improve the sales force of commodities. With the growing demand for food safety, it is more and more necessary to display information such as origin, producer, production date and shelf life on food or food packaging. At the same time, people have higher requirements for food packaging materials and inks used for food and food packaging printing, especially inks that are in direct contact with food. However, the formula of traditional ink contains a large number of harmful i...
