Synergistic effects of NaOCl and ultrasound combination on the reduction of Escherichia coli and Bacillus cereus in raw laver.

摘要: Abstract The current study investigated the synergistic effects of NaOCl (50–200 ppm)/ultrasound (37 kHz, 380 W for 5–100 min) combination on reduction Escherichia coli and Bacillus cereus in raw laver. reductions were not dependent concentrations times ultrasound. Synergistic ranged from 0.1 to 0.5 log10 colony-forming units (CFU)/g 0.1–1.1 CFU/g, respectively, E. B. cereus, with largest 200 ppm 60-min Moreover, significant differences “L” (lightness), “a” (redness), “b” (yellowness) observed combined 50–200 ppm 100-min ultrasound compared those laver treated by only results indicate that treatment could be regarded a potential optimum hurdle approach seaweed production, processing, distribution process enhanc...
