The Gram-negative Psychrotrophic bacteria (PTC) are the major group of microorganisms responsible for spoilage of aerobically stored fresh meat at chilled temperatures . In our study, the initial PTC (day 0) of samples ranged from 3.19 log CFU/g, in PJ–CH–Z 2% samples, to 4.10 log CFU/g in controls (Fig. 1e). Additionally, the growth pattern of PTC showed that control being the highest at day20 (10.37 log CFU/g), followed by PJ treatment (8.97 log CFU/g), PJ–CH
(8.43 log CFU/g), PJ–CH–Z 1% (7.45 log CFU/g) and the lowest count (7 log CFU/g) was detected in PJ–CH–Z 2% samples. Similarly, it has been reported that pomegranate juice phenolics inactivated Psychrotrophic bacteria in chicken breast meat under refrigerated storage
