selection of proteins which may be processed using milder temperatures
might be a key factor for the development of biodegradable/
bioactive materials containing volatile antimicrobial agents. It is
possible to calculate the biocide fraction released (mg biocide into
water/mg biocide initial in the protein matrix) at every bioplastic
concentration. These calculations show that just about 39% and
73% of the initial biocide added is released for samples containing
5 and 10 wt.% FA, respectively. The remaining quantity of biocide
may have gone during processing or may be reacted with the protein
matrix.
