Abstract

The invention relates to an edible antibacterial ink prepared by blinding, mixing, grinding, adjusting, inspecting and processing raw materials. The raw material comprises the following component in percentage by weight: 20-65 percent of edible binder, 10-40 percent of edible addition agent, 20-50 percent of edible coloring material and 2-40 percent of diluting agent, wherein the binder is gadoleic acid solution of chitosan. The edible antibacterial ink not only has common characteristics of ink, but also can directly upholster the surfaces of food and medicines, avoid the safe problem of the food and medicines caused by printing ink, improve the grade of the food and the medicines and simultaneously has the functions of inhibiting and sterilizing strains which often exist in the food and keeping freshness and ensuring the quality.

Description

technical field [0001] The invention belongs to the scope of printing materials, in particular to an edible antibacterial ink. Background technique [0002] Printing inks play a pivotal role in the printing and packaging industries. However, because traditional ink contains a large number of harmful ingredients, especially gasoline, benzene and its derivatives, kerosene, alcohols, etc. involved in the manufacture and use of solvent-based inks, it has caused great harm to the health of front-line workers. threat. Especially when these inks are used for the printing of food and medicine, they will directly or indirectly pollute these items and endanger people's health. Now popular water-based ink, although water replaces the poisonous organic solvent in the traditional ink, has reduced the pollution to atmosphere, has also improved the environment of printing workshop, discloses a kind of water-based metal printing ink that is easy to remove as Chinese patent CN1421498A, It...
