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 . In other studies involving preservation of fresh sausages stored under refrigeration, combinations of chitosan with sulphite and chitosan with rosemary extract led to a reduction of almost 3 and 2 log cycles, respectively.
