In this work, a preliminary in vitro evaluation of antimicrobial
activity of NEW, obtained with different salts, was carried out
simulating washing water contaminated by spoiler Pseudomonas
strains; furthermore, the efficacy of NEW was studied on spoilage
bacterial population contaminating fresh cut lettuce paying
particular attention to the fate of spoilage pseudomonads. Changes
in visual quality of lettuce leaves, stored in passive modified atmosphere,
was recorded during cold storage.
