Antifungal whey protein films activated with low quantities of water soluble chitosan

The aim of this work was to develop antifungal films from whey protein isolate (WPI) added with low quantities of a water soluble derivative of chitosan (WSCh), which was obtained through a Maillard reaction with glucosamine hydrochloride. Glycerol was used as plasticizer and sodium tripolyphosphate was added to neutralize WSCh charges, at a working pH of 6.4, to avoid coacervation due to the opposite charges interaction of both biopolymers....
