Ink printing materials to lead the development of new trend: Edible ink – printi
Abstract: The edible ink on the status quo and future development applications described, and its main components were introduced in detail. Key words: edible ink; environmental protection; pigment; connection material as the continuous development of modern industry, printing industry in the production and living status in the increasingly important. Printing industry is often a measure of a country's industrialization and modernization of an important symbol. Printing ink as a coloring material, in packaging and printing played a vital role. However, some conventional ink composition of the raw materials contain some harmful substances, such as is now widely used in soft plastic package printing Solvent Inks that contain volatile organic compounds (VOC) a great harm to the human body, though, now people have started to target turned green ink VOC free, for example, Water-based ink , But these can not be edible ink itself, can not directly print on the surface of food or drugs. In this case, a new born printing ink, printing ink can diet. This ink printed directly on the surface of food and drugs has become a new bright ink developed. 1, Edible Ink 1, situation and development prospects. Research edible ink in a foreign country are already visible, and many research institutions and power companies have launched their own ink formula and a more mature applications, and in many consumer products company has been successfully applied. Japan's Toyo Ink Edible ink developed more mature, the market has been put into use; cleaning company will own production of edible ink printing unit of Pringles on the surface, to obtain a better effect on the market; the United States Spectra has introduced the MelinFC and ApolloJetXpress4/256FG edible food imaging system using a digital ink jet printing on food surfaces, bright colors, high performance; In addition, the Japanese printing machine manufacturer Masitama Anglo-German company has recently successfully developed and produced out a way to use edible ink printed directly on the surface in the food edible ink printer. In terms of domestic edible ink A few studies, research technology is not mature enough, and expensive, the average price over all 1000RMB/KG, not suitable for heavy printing. 2. The development prospects of the edible products, including food, medicines and edible packaging materials for surface printing is a new idea to try is a new and attractive market opportunities, for example, cookies, candy, chocolate, etc. printed on the surface of some fine food patterns, is bound to increase people especially attractive to children of such foods, and food packaging bags with edible ink can greatly reduce the pollution of traditional ink on food. But the market is rarely applied edible ink, primarily in the drug surface printing, and color monotonous, simple images, mainly because of the edible ink technology is not very mature, I believe the study with the edible ink in-depth, technology continues to evolve, it will apply to a broader area, more and more people will come into contact with edible ink products. 2, edible ink is a major component of traditional ink binders, pigments, additives composition. Binders in turn, resin, oil (vegetable oil, mineral oil) and organic solvents and Supplementary material Composition. Pigments and dyes, pigment mainly. Edible ink is the connection theory, materials, pigments, additives composition, but its composition is completely different elements. Of the edible ink, its higher standards, it is adaptable to meet the printing and color requirements, ensure that the printing ink can be transferred to the substrates to be, but also meet the characteristics of edible, therefore, part of the to the whole of this point of view, each component of the ink, must comply with the requirements of human consumption, and they mixed with each other the role of the physical or chemical substances produced should also be harmful to humans, to meet the food requirements to ensure that the final ink to meet the state designated by the relevant standards. Therefore, the edible ink of research is in its choice of ingredients. 1. Pigment of choice due to have edible, it can not be a paint pigment but edible pigment. Pigments can be divided into natural pigments and synthetic pigments. A wide range of natural pigment, natural color, many varieties of both nutritional value, and some also have some medication effects (such as yellow, saffron yellow, etc.), especially their safety has been trusted by people, but most natural pigment is not stable enough, with acids, alkali, heat and other external factors, its molecular structure will change, resulting in its discoloration. The synthetic pigment, although the majority of the adverse human health, but it has bright color, strong coloring, good stability, easily soluble in water, easy to color, quality and uniformity, and lower cost, has been widely used.
