Briefly, four types of actives systems (coating, films obtained
by casting and films obtained by extrusion) based on chitosan
were prepared and characterized by several analytical techniques.
The DA for the different samples determined by FT-IR
varied from 9.5 (chitosan obtained from shrimp) to 66.7
(commercial standard medium Mw).
From the data obtained by the different techniques, it can
be concluded that sample C1 is the one with a higher antimicrobial
capacity.
