Roller et al. (2002) developed a novel
preservation system involving a combined use of chitosan glutamate, carnocin and sulphite for preservation of pork sausages.
Recently, Georgantelis, Ambrosiadis, Katikou, Blekas, and
Georgakis (2007) studied the effect of rosemary extract, a-tocopherol and chitosan on microbial parameters and lipid oxidation of
fresh pork sausages, while Kanatt, Chander, and Sharma (2008)
studied the preservative effect of mint and chitosan mixture on
pork cocktail salami
