Shelef and Yang (1991) suggested that foods containing higher moisture content (%), such as comminuted beef and chicken, did not significantly affect aw by the addition of SL, as compared to those containing less water. During 8 weeks of refrigerated storage, pH values pooled over treatments tended to decrease, resulting in the differences in pH value at 4 weeks from that of initial storage, however, aw values were not changed with storage time (Table 5). Our results indicated that storage time had effect on pH, but no effect on aw values. These confirmed results of Bloukas et al. (1997) who reported that pH was affected by storage time, but not affected by the addition of SL.
