CARVALHO, R. A., Autor ; SOBRAL, PAULO JOSE DO AMARAL, Autor ; FAVARO-TRINDADE, C. S., AutorEdible films are thin materials based on biopolymers from renewable sources, and plasticizers. Normally plasticizers are colorless low molecular components. The use of natural pigments may be valuable for the edible film technology. The choice o[...]
