Effect of Relative Humidity and Storage Temperature on the Behavior of Listeria Monocytogenes on Fresh Vegetables

The survival and growth of Listeria monocytogenes on fresh lettuce (Lactuca sativa), cucumber (Cucumis sativus) epidermis and parsley (Petroselinum sativum) under different relative humidity (RH) conditions and storage temperatures was studied. Inoculated vegetable pieces were stored at 10C for 7 days, 20C for 5 days, and 30C for 24 h, and at 53 and 90% RH. L. monocytogenes was enumerated perio...

Emerging Perspectives on the Natural Microbiome of Fresh Produce Vegetables

Plants harbor a diverse microbiome existing as bacterial populations on the leaf surface (the phyllosphere) and within plant tissues (endophytes). The composition of this microbiome has been largely unexplored in fresh produce vegetables, where studies have tended to focus on pathogen detection and survival. However, the application of next-generation 16S rRNA gene sequencing approaches is begi...

Meta-Analysis of Studies on Vitamin C Contents of Fresh and Processed Fruits and Vegetables

The effects of processing and preand post-harvest handling on nutritional contents, vitamin C in particular, of fruits and vegetables have been extensively researched and well documented. While fresh produce is not subjected to nutrition deterioration inevitable in chemical and thermal processing, nutrient reduction due to suboptimal storage conditions and time can be substantial. Processed pro...
