Inactivation of Listeria monocytogenes and Salmonella Typhimurium in strawberry juice enriched with strawberry polyphenols

BACKGROUND Low molecular‐weight phenolic fractions (LMPFs) were extracted from Albion (LMPF‐A) and Camarosa (LMPF‐C) strawberry cultivars. Their antibacterial activity against Listeria monocytogenes and Salmonella Typhimurium cocktails in vitro and in vivo was investigated using strawberry juice as a food model. This study also sought to determine their antibacterial mechanism. RESULTS Quercetin was identified as a principal compound in both...
