Problems solved by technology

An edible ink can be prepared by using the above technical solution, but it lacks antiseptic function. Even if the bactericide has a certain bactericidal effect, because its juice is quickly oxidized, the growth of bacteria affects the edible safety of the ink. On the other hand , the above-mentioned fungicides were not further treated due to the presence of their secondary compounds, which affected the odor of edible inks
Chinese patent CN108017949A discloses a kind of edible ink, comprises combination resin, combination solvent, edible pigment, auxiliary agent, wherein, auxiliary agent comprises antioxidant preservative, specifically is vitamin C sodium, and it is medicine synthesis compound, although compared Vitamin C is more stable, but it is not preferred to use it as a chemically synthesized antioxidant
The preparation and research of a chitosan-citric acid complex is disclosed in the Chinese literature "Chinese Food Additives", and the method for the synthesis and preparation of the complex is introduced in detail, but it only makes relevant preparations and does not describe it in Application in specific food fields, while overcoming possible technical difficulties

Abstract

The invention discloses a safe edible ink for food and drug surface printing, which comprises a binder, a color paste, a solvent, a plasticizing humectant, a dispersing agent, a preservative and a toughening agent, wherein the preservative and the toughening agent are citric acid derived from orange peel; the color paste is color paste derived from vegetables or color paste prepared from anthocyanin; the binder is a mixture of starch and vegetable gum; the solvent is deionized water; the plasticizing humectant is glycerol; the dispersing agent is polyethylene glycol; and the cross-linking agent is calcium chloride and / or adipic acid. The invention provides food and drug surface printing ink which is effective in corrosion prevention and toughening, higher in edible safety level and more stable in performance. Meanwhile, the invention further discloses a preparation method of the edible printing ink, wherein the method is easy to operate, and the prepared printing ink product is stable.

Description

technical field [0001] The invention belongs to the technical field of food printing materials, and relates to a formula and a production process of a safe edible ink used for food and drug surface printing. Background technique [0002] With the improvement of people's awareness of food safety levels, the requirements for food and drug packaging and printing inks for food are becoming more and more stringent. However, although traditional inks have better printing and adhesion effects, they contain unsafe ingredients or chemical synthetic ingredients for the human body. For inks printed on the surface of food or medicine, each component should be edible, and all components will not undergo chemical changes after mixing, which will cause harm to the human body, and will not pollute food and medicine after printing. [0003] For example, the patterns printed on the surface of biscuits, snacks, chocolates, and fruits, and the trademarks or marks printed on the surface of medi...
