主 题：curcumin light-emitting diode pH refrigeration temperature Staphylococcus saprophyticus
摘 要：Objectives:As considered highly resistant to antibiotics like mecillinam,the rise of Staphylococcus saprophyticus(***)contamination of fresh foods and food processing environments necessitates the development of a new antimicrobial approach for food safety *** study aimed to investigate the synergistic effect of food-grade curcumin(CUR)and blue light-emitting diode(LED)on *** and Methods:***/ciys was subjected to the synergistic treatment at 4℃ and 25℃.The influence of parameters,including CUR concentration,light dose,and pH incubation time on the inactivation of *** vjqs characterized through plate counting ***:The combined treatment of CUR and blue light irradiation significantly(P0.05)reduced bacterial counts and the antimicrobial effect was in a CUR concentration and light dose-dependent ***,refrigeration temperature(4℃)significantly(P0.05)enhanced the antibacterial effect at neutral pH condition(6.2-72),resulting in approximately 6.0 log *** acidic condition(pH 2.2-5.2),there was no significant difference in bacterial population reduction between treatments at both ***:These findings proposed that synergistic interaction of CUR and 460 nm LED under refrigerated temperature could enhance the inactivation of *** at neutral pH condition.
