Penetration of surface-inoculated bacteria as a result of electrically generated hydrodynamic shock wave treatment of boneless skinless chicken breasts.
The top surface of boneless skinless chicken breasts was inoculated with either green fluorescent protein (GFP)-labeled Escherichia coli (E. coli-GFP) or rifampicin-resistant E. coli (E. coli-Rif) and subjected to electrically generated hydrodynamic shock wave treatment (HVADH). Cryostat sampling in concert with laser scanning confocal microscopy or plating onto antibiotic selective agar was us...
متن کاملEffect of Hydrodynamic Pressure Treatment Andcooking on Inactivation of Escherichia Coli O157:h7in Blade-tenderized Beef Steaks
The efficacy of hydrodynamic pressure (HDP) treatment for inactivation of Escherichia coli O157:H7 in blade-tenderized beef steaks was studied. Beef steaks (N = 48) were inoculated with a five-strain cocktail of Escherichia coli O157:H7 and treated with blade tenderization (BT), HDP or a combination of BT followed by HDP (BTH). Control and treated steaks were cooked to 54.4C (undercooked), 62.8...
متن کاملEffects of low-dose, low-penetration electron beam irradiation of chilled beef carcass surface cuts on Escherichia coli O157:H7 and meat quality.
Low-dose, low-penetration electron beam (E-beam) irradiation was evaluated for potential use as an antimicrobial intervention on beef carcasses during processing. The objectives of this study were (i) to assess the efficacy of E-beam irradiation to reduce concentrations of Escherichia coli O157:H7 on a large beef surface and (ii) to evaluate the effect of the treatment on the sensory properties...
متن کاملبررسی اثر رشد و تکثیر تعدادی از باکتری‌های لاکتیک روی تحول میکروبی گوشت چرخ کرده گاو در شرایط صنعتی
The effects of growth of two strains of lactic acid bacteria on microbial flora of ground beef after packaging in air permeable packs were studied under workshop conditions. The strains isolated from dairy products were added to ground beef at a density of 104 CFU/g after identification and antibiosis test against indicator bacteria (Escherichia coli and Staphylococcus aureus). The two strains ...
