Abstract
In an attempt to improve the bacteriological quality and refrigerated shelf life of broiler meat, 10-min surface wash treatments with sterile distilled water (DW), 8% (wt/vol) water extract of sumac (Rhus coriaria L.) fruits (WES), and 2% (vol/vol) lactic acid (LA) were compared by using a broiler wing model. The aerobic plate counts (log10 cfu/g) of psychrotrophs, mesophilic aerobes, Enterobacteriaceae, coliforms and presumptive fecal coliforms on the samples were determined. Immediately after a 10-min decontaminaton, the mean count of all the bacterial groups was determined to be 3.9, 2.6, and 1.7 (log10 cfu/g) for DW, WES, and LA, respectively. Because the postdecontamination population level of psychrotrophs, mesophiles, and Enterobacteriaceae were low in the LA-treated group compared to the WES group, an equity between the 2 groups in the point of view of the 3 bacterial groups existed at d 10 of cold storage (3 +/- 1 degrees C). Shelf life was 7 and 14 d for wings treated with DW and WES, respectively, whereas the LA-treated wings did not spoil after 14 d of cold storage (3 +/- 1 degrees C). Nevertheless, an undesirable pale color and an acidulous odor occurred in the LA-treated wings. In contrast, a good color appeared on the WES-treated wings, which was also superior to the color of the DW-treated wings. Such advantages of WES may be important for poultry processors and for consumers. However, the immediate decontamination and refrigerated shelf life extension potential of WES should be intensively studied in antimicrobial interventions in poultry processing plants.
