可食性油墨及其印刷适性

研究制备了一种新型可食性油墨,该可食性油墨的组分为m(蒸馏水)∶m(蔗糖)∶m(食用色素)∶m(黄原胶)∶m(大豆油)=20∶35.8∶1∶0.2∶43。用丝网印刷方式将其印刷在铜版纸与胶版纸上,并对印品的密度、牢固度、光泽度等印刷适性进行了测定与分析。结果表明,印品牢固度为87.8%～93.3%,达到了相关国家标准的要求,能够应用于食品或药品的纸质包装印刷,并且该可食性油墨在铜版纸上的密度和光泽度明显优于胶版纸,更适合表面经涂布的纸质承印材料。

Edible ink and its printing performance

A new type of edible ink was prepared,the composition of which is m(distilled water)∶m(sucrose)∶m(artificial color)∶m(xanthan gum)∶m(soybean oil)=20∶35.8∶1∶0.2∶43.The printability,density,firmness and glossiness was studied when the ink was printed on coated paper and uncoated paper by screen printing technology.The result showed that the firmness range of the presswork was 87.8% to 93.3%,which can reach the national standard.The density and glossiness of the ink printed on coated paper was obviously better than that printed on uncoated paper,suggested that the ink was more suitable for coated paper material in printing.
