Technical Field

The invention belongs to the technical field of food printing materials, and relates to a formula and a manufacturing process of safe edible ink for printing on the surfaces of food and medicine.

Background

With the improvement of the awareness of food safety level, the requirements for packaging food and medicine and printing ink used on food are more and more strict. However, although the traditional ink has good printing adhesion effect, the traditional ink contains unsafe components or chemical synthetic components for human bodies. The printing ink printed on the surface of food or medicine has all the components with edibility, and all the components are mixed without chemical change and harm to human body.

Such as patterns printed on the surface of biscuits, snacks, chocolates, fruits, trademarks or marks printed on the surface of drugs or capsules, trace the traceability of the drugs.

At present, the production technology of edible ink directly applied to the surface printing of food and medicine is not mature, only a few products can be printed on the surface of food and medicine in the market, and certain defects are also existed, such as: the color is monotonous, the color saturation is not enough, the uniformity and the pattern definition are not enough, and the food safety is not high.

The traditional edible ink is usually natural toner, edible colloid is added, vegetable oil, animal oil and water are mixed to be used as a solvent, and auxiliary agents are added to stabilize a system. At present, some edible printing ink has the defects of unsafe components, insufficient green degree, high safety level of mixed food, corrosion resistance loss, large brittleness and easy cracking of the surface.

Chinese patent CN107033663A discloses an edible ink and a preparation method thereof, and particularly discloses an edible connecting agent, an edible auxiliary agent, an edible pigment and a bactericide, wherein the bactericide is one or more of ginger juice, onion juice or garlic juice. By using the technical scheme, the edible ink can be prepared, but the edible ink is lack of an antiseptic function, even if the bactericide has a certain bactericidal effect, the edible safety of the ink is affected due to the fact that the juice of the bactericide is oxidized quickly and bacteria breed, and on the other hand, the bactericide is not further processed due to the existence of secondary biochemical compounds, so that the smell of the edible ink is affected. Chinese patent CN108017949A discloses an edible ink, which comprises a combination resin, a combination solvent, an edible pigment, and an auxiliary agent, wherein the auxiliary agent comprises an antioxidant preservative, specifically sodium ascorbate, which is a pharmaceutical synthetic compound, and although it is more stable than vitamin C, it is not preferred to use it as a chemically synthetic antioxidant.

Chinese patent CN101709184B discloses an antibacterial ink, and specifically discloses that a dilute acid solution with chitosan as a binder is added into the raw material of the ink, and the solution plays a role in inhibiting the reproduction of microorganisms in addition to the advantages brought by the property of chitosan, and plays a role in resisting and inhibiting bacteria. The Chinese document 'Chinese food additive' discloses the preparation and research of a chitosan-citric acid compound, and specifically introduces a synthetic preparation method of the compound, but the chitosan-citric acid compound is only prepared in relevant aspects, is not applied to the specific food field, and simultaneously overcomes the possible technical difficulties.
