摘要

The effect of decontamination methods on fresh-cut vegetable washing waters was evaluated.rnNEW, ClO_2, organic acid-based product FPW, and UV-C were tested with and without an interferingrncarrot juice of 1% (IS), on Yersinia enterocolitica and Yersinia pseudotuberculosis, Escherichia coli,rnand yeast Candida lambica. The use of ClO_2 (50 ppm active chlorine) resulted in >4 log reductionrnof Y. enterocolitica, Y. pseudotuberculosis, E. coli and >3 log reduction of C. lambica. The antibacterialrneffect of NEW was less effective in the presence of IS when compared with ClO_2. Therninactivation of C. lambica by FPW reached a maximum of 2.8 log cfu/mL (concentration 0.125%),rnbut the antimicrobial effect was delayed by the IS. The effect of FPW on E. coli was significantlyrnreduced by 1% IS. The inactivation of E. coli and C. lambica with UV-C IS decreased the inactivationrnand lengthened its time. Filtration improved the effect of UV-C inactivation.
