Study of Edible Ink

In order to print chromatic color and pattern on the surface of food, medicine and edible materials, and also print on the package of food, medicine and some other produces, the new ink with chromatic color, environmental nontoxic and edible is needed. In this paper, based on the principle of traditional ink, a kind of edible ink is prepared through reasonable materials selection and a larger number of experiments, and studied on its relevant performances. The conclusion indicates that the edible ink has good trait in mobility, thixotropism, color rendering and printability, and can be used as a reference in the future research.
