Problems solved by technology

However, these inks are highly susceptible to significant fading and discoloration through photolysis and oxidation by exposure to light
In order to meet the needs of light printing, when the amount of natural pigments used is reduced, the degree of printing will become lighter, and the discoloration and fading caused by light and air oxidation will be more obvious. It is very difficult to maintain the vividness of text and patterns after printing. of

Abstract

The invention relates to edible printing ink and a preparation method thereof. The edible printing ink is composed of the following components in parts by weight: 2-5 parts of a natural pigment, 0.05-1 part of a myrica rubra extract, 1-4 parts of gum arabic, 15-25 parts of ethanol with a concentration of over 95% (v/v), and 70-80 parts of ion exchange water. The edible printing ink is prepared through a mixing method. The edible printing ink can be applied to the printing fields of foods, medicines, drugs for external use, cosmetics, feeds, or packaging containers directly contacted with foods, and is not discolored and faded due to illumination and air oxidation; according to the edible printing ink, bright words and patterns can be obtained; and the preparation method is simple, and meets the needs of large-scale industrial production.

Description

technical field [0001] The invention relates to the field of ink production, in particular to an edible ink and a preparation method thereof. Background technique [0002] Edible inks are widely used in the packaging of food, pharmaceuticals, external medicines, cosmetics, feed and other containers, all of which are made of edible materials. The printing methods of food, medicine, external medicine, cosmetics, feed or packaging that directly contact the container include inkjet printing, gravure printing, screen printing, flexographic printing, transfer printing, electrostatic printing, etc. [0003] Taking gravure printing and flexographic printing as examples, the edible ink is characterized by containing shellac and food coloring; taking screen printing as an example, the edible ink after emulsifying water, food coloring, and edible oil with an emulsifier, with There are water, alcohol, surfactants, edible insoluble inorganic powder, stabilizers, thickeners and necessary...
