Influence of Modified Atmosphere Packaging on the Microflora and Quality of Fresh Bell Peppers

Abstract

Fresh bell peppers were individually shrink-wrapped in film (SW), sealed in gas-flushed (5% O2, 10% CO2, 85% N2) film (GP) pouches, or stored unpackaged in cardboard packing crates (CN). All samples were stored at 13°C and changes in populations of total aerobic microorganisms, yeasts and molds, members of Enterobacteriaceae , and lactic acid bacteria were determined. In addition, overall sensory quality, color changes, and surface pH were monitored. SW peppers developed higher populations of total aerobic microorganisms, yeasts and molds, and Enterobacteriaceae than did CN peppers, but populations of other groups of microorganisms were similar. Color and surface pH of peppers did not differ in any of the treatments. SW and GP peppers remained unspoiled at least 6 weeks, whereas CN peppers spoiled in 3 weeks.
