Evaluation of the genotoxicity of chitosan nanoparticles for use in food packaging films

Autor: Leonardo Fernandes Fraceto, Renata de Lima, Anderson do Espirito Santo Pereira, Márcia R. de Moura, Luiz H. C. Mattoso, Fauze A. Aouada, L. O. Feitosa

Publikováno v: Journal of food science. 75(6)

The use of nanoparticles in food packaging has been proposed on the basis that it could improve protection of foods by, for example, reducing permeation of gases, minimizing odor loss, and increasing mechanical strength and thermal stability. Consequ
