With regard to yeasts/molds species known to be involved in the spoilage of chicken meat, all of the antimicrobial treatments examined in the present study caused significantly lower (P b 0.05) counts for yeasts/molds in PJ, PJ–CH, PJ–CH–Z 1%and PJ–CH–Z 2% chicken samples as compared to the control samples during the storage period (Fig. 1f).
Antifungal activity of PJ against different kinds of molds and yeasts has been reported (Dahham et al., 2010). In other studies involving preservation of fresh sausages stored under refrigeration, combinations of chitosan with sulphite and chitosan with rosemary extract (Georgantelis et al., 2007) led to a reduction of almost 3 and 2 log cycles, respectively.
