- aggregation title "High oxygen concentration in combination with elevated carbon dioxide to affect growth of fresh-cut produce micro-organisms".
- aggregation abstract "High oxygen atmospheres (> 70 %) can be used as an alternative for the nowadays applied low O-2/elevated CO2 modifled atmosphere, to prolong shelf life of respiring fresh-cut vegetables and fruit. The effect of high oxygen atmosphere, applied alone or in combination with elevated CO2 concentrations, on the growth of spoilage micro-organisms (14 species) and pathogens (Listeria monocytogenes and Aeromonas caviae (HG4)), isolated from fresh-cut produce, has been studied. Of each species only one strain was considered, except for Candida lambica, from which 5 different strains were analyzed to check possible differences in sensitivity for high O-2 concentrations between strains of the same species. Lag phase (lambda), maximum specific growth rate (mu(max)), initial count (N-0) and maximum count (N-max) were determined applying the Baranyi model. The maximum specific growth rate of G(-) spoilage bacteria was slightly reduced by high O-2. Growth rate of the two tested pathogens was rather stimulated by high O-2. Lactic acid bacteria were much more sensitive to high O-2 concentrations, but no additive or synergistic effect was found when high O-2 was combined with high CO2. In most of the cases, growth of yeast strains was strongly inhibited by high O-2, and this effect was even more pronounced when applying 80 % O-2 + 20 % CO2 (additive effect). Only one strain of Candida lambica was not at all affected by high O-2 concentrations and/or elevated CO2. Growth of Candida humicola and of another strain of Candida lambica was significantly stimulated by high O-2. So although yeast are generally inhibited during storage experiments with fresh-cut produce under high O-2 atmosphere, this inhibitory effect is not true for every individual yeast strain in in vitro experiments.".
