Problems solved by technology

However, due to the fact that most of the existing matrix formulations used for printing on edible ink bases contain synthetic chemical components and non-natural raw materials, it is difficult to meet the relevant standards of national food and drugs, which limits the development of food and drug printing.

Abstract

The invention relates to a matrix for edible ink substrate lettering and a preparation method thereof. The matrix comprises the following components in part by weight: 30-70 parts of ethanol, 20-45 parts of shellac, 15-30 parts of titanium dioxide and 1-5 parts of aid. The method comprises the following steps of: adding the shellac into the ethanol; continuously stirring to fully dissolve the shellac so as to obtain a shellac solvent; adding the titanium dioxide and the aid into the shellac solvent; continuously and uniformly stirring to obtain a uniformly mixed solution; adding the uniformlymixed solution into a colloid mill; and grinding to obtain a finished product. Compared with the prior art, the substrate has the advantages of high adhesion, low corrosion, non-toxicity, high oil resistance, high acid resistance, high color fixing performance and the like.

Description

technical field [0001] The invention relates to a substrate for printing on edible ink bases, in particular to a substrate for printing on edible ink bases and a preparation method thereof. Background technique [0002] Food or pharmaceutical printing includes techniques for printing on edible substrates such as capsules and tablets. Edible ink (Edible Ink) is a special ink, which not only has the general commonality of printing inks, but also has gradually been widely used in food (or pharmaceutical) surface decoration, or packaging and printing of such products because of its edible properties. Therefore, edible inks will surely bring new market growth points to the food and pharmaceutical industries, printing and packaging industries, and it is of great significance to research and develop the inks. [0003] For edible inks, to meet the printing adaptability, it should also have the general composition of printing inks, such as pigments (coloring materials, pigments), so...
