Special Issue Information

Dear Colleagues,

Fresh fruits and vegetables are nutrients rich commodities. These are an imperative source of various essential nutrients which are considered critical for the normal health and well-being of humans. However, fresh fruits and vegetables contain higher water content which makes them highly perishable and susceptible to certain microbial infestations including bacterial and fungal pathogens. In addition, certain physiological disorders such as chilling injury also detrimentally influence the storage potential and eating quality of fruits and vegetables. Therefore, appropriate handling and storage are indispensable during postharvest; so, that quality of fruits and vegetables can be improved and/or maintained by ensuring extended storage life potential and microbial safety. To achieve these objectives, it is important to explore innovative and emerging technologies for the conservation of postharvest quality and achieving microbiological safety of fruits and vegetables. In addition, preharvest factors/treatments affecting postharvest storage and microbial safety are equally important. Therefore, a Special Issue has been planned in this perspective to explore the potential of emerging technologies for the preservation and microbiological safety of fruits and vegetables. In this Special Issue, all types of research/review articles are welcomed on the innovative and emerging postharvest technologies to conserve the quality and attain microbial safety of fruits and vegetables.

Papaya fruit has a limited shelf life due to its sensitivity to decay and chilling damage during cold storage. The application of methyl jasmonate (MeJA) is known to reduce the incidence of disease and chilling injury, and to maintain the overall quality of the papaya fruit when stored at low temperature. Consequently, the effects of postharvest MeJA (1 mM) immersion on papaya fruits during low-temperature storage (10 °C ± 2 °C) for 28 days were studied. The experiment revealed that MeJA treatment significantly decreased the papaya fruit’s weight loss, disease incidence, and chilling injury index. Furthermore, the accumulation of malondialdehyde and hydrogen peroxide was markedly lower after the application of MeJA. In addition, MeJA treatment exhibited significantly higher total phenols, ascorbic acid, antioxidant activity, and titratable acidity in contrast to the control. Similarly, MeJA-treated papaya fruits showed higher antioxidant enzymatic activity (superoxide dismutase, catalase, and peroxidase enzymes) with respect to the control fruits. In addition, MeJA reduced the soluble solids content, ripening index, pH, and sugar contents compared to the control fruits. Furthermore, MeJA-treated papaya fruit exhibited higher sensory and organoleptic quality attributes with respect to untreated papaya fruits. These findings suggested that postharvest MeJA application might be a useful approach for attenuating disease incidence and preventing chilling injury by enhancing antioxidant activities along with enhanced overall quality of papaya fruits during low-temperature storage.
