Preliminary Study on the Green Anti-Counterfeiting Printing Materials

Abstract:

By using DiaionHP-20 and SephadexLH-20 to isolated and purify the pigment of Rhododendron simsii, a high concentration of fluorescent substances from plant organs was obtained, and then study on the anti-counterfeit marking test was carried out. The result reveals that though extracting the pigment in the petals by SephadexLH-20, 5 different fluorescence regions can be clearly seen, of which the yellow-green region was the most obvious one. Fluorescent pigment from plant organs is plant secondary organic metabolites which have non-toxic, non-radiation matters to human. Thus the deeper research of the fluorochrome from plant organ could not only be used in the antibacterial activity of fresh food preservation aiming at preventing the abuse of chemical preservation substance, but also develop a new type of anti-counterfeit printing materials---natural water-based fluorescent ink, and the result brings business opportunities to the new industry of “green anti-counterfeit printing”.
