The technology of laser marks can replace sticky labels
Small sticky labels can be replaced with fruit and vegetables technology of drawing of a tattoo ăusing laser. Now this technology passes testing at University of Florida (UFL) and in Agricultural research service of the USA (ARS).
Named by the laser marking, the new technology allows to put tatoo on grapefruits and other products. Owing to this marking products can be identified on cash departments. The technology for the first time has been offered by former employee of UFL scientists Greg Drouillard. And the laser technology by microbiologist Jan Narciso from laboratory on research of citron both subtropical production ARS and researcher Ed Etxeberria from UFL has been developed.
Till now the sticky label which is not the ideal decision is put on grapefruits and other products. They come easily unstuck, pasted to each other during transportation and storage, complicating that process of identification of a product.
The technology consists that by means of a laser beam on carbonic gas marks is put on depth of several external cellular layers of a skin of fruit or a vegetable. Tatoo it is impossible to wash off, erase or change. Also this permanent marks does not cause excessive loss of a moisture or penetration of pathogenic microorganisms as tatoo in addition becomes covered by wax.
The further researches have shown, that probably wax is not required, as carbonic gas effectively "solders" microapertures in a skin. During testing for fruit placed pathogenic microorganisms, and then put laser marks. As a result neither in a skin, nor in the fruit of microbes it was not revealed. However for prevention of loss of a moisture drawing of wax all the same is recommended.
