Lactic acid and trisodium phosphate treatment of lamb breast to reduce bacterial contamination.

摘要: Lactic acid and trisodium phosphate (TSP) were evaluated for the ability to reduce Escherichia coli aerobic plate counts (APCs) on lamb breasts that inoculated with a fecal paste. A 90-s water rinse was applied followed by either 9-s (55°C) 2% lactic spray, 60-s 12% TSP dip, or combined treatment of both treatments. reduced E. APCs 1.6 log 10 /cm 2 . caused 1.8-log reduction in coil 0.7-log APCs. Combined reductions spray dip 1.8 1.5 roll APCs, respectively. phosphate, used alone combination, effective reducing numbers could be useful as pathogen intervention steps slaughter processing. Reduire ou prevenir la contamination des carcasses pendant l'abattage permet d'assurer un produit plus sain. En ce qui concerne l'agneau, presence de matieres fecales sur laine augmente initiale carcasses. Les taux coliformes correspondent avec probabilite l'enlevement peau et l'evisceration. L'acide lactique est agent antimicrobien efficace dans le trisodique alcalin utilise microorganismes les viandes. Cette etude teste capacite bacteries aerobies d'une vaporisation d'acide immersion du (55°C). Elle mesure performance ces traitements separes combines pour evaluer strategie d'intervention efficace.
