Abstract

The invention relates to edible ink and a preparation method thereof. The ink comprises the following components in percentage by weight: 30 to 70 percent of ethanol, 20 to 45 percent of lac, 10 to 35 percent of edible ferric oxide colorant and 0 to 1 percent of assistant. The ink is prepared by the following steps: adding the lac into the ethanol and constantly stirring till the lac dissolves completely to obtain solution of lac; adding the edible ferric oxide colorant and the assistant into the solution of lac; constantly and uniformly stirring to obtain uniformly mixed solution; filling the uniformly mixed solution into colloid mill; and milling to obtain a finished product. Compared with the prior art, the ink has the advantages of high adhesivity, low corrosivity, no toxicity, no harm, high oil resistance, high acid resistance, and high color fixing performance.

Description

technical field [0001] The invention relates to an edible ink, in particular to an edible ink 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), solvents, and so on. Considering that the edible ink is directl...
