i saw it time ago in a magazine from my country, that companies which used it should put in the ingredients list or would be sanctioned.

maybe next thing will be edible paper

Edible paper has been out for a long time.  It is called rice paper and can be bought in some herb catalogs and can be bought from specialty supplies for cakes, etc:
