Evaluation of perforation-mediated modified atmosphere packaging for the commercialization of bulk purple passion fruit under refrigeration.

Modified atmosphere packaging (MAP) is widely used to preserve fresh fruits. In the case of exporting products in bulk formats (2-5 kg), perforated MAP can help extend shelf life if appropriately configured to reach suitable gas levels. This study evaluated the configuration of a perforated MAP system for purple passion (Passiflora edulis Sims) fruits based on modeling and simulation of changes in gas levels within the package headspace and experimental data on the respiration and transpiration of the fruits.

ZrO core cluster with formula unit [ZrO(OH)(OH)(CHCOO)(SO)]·HO obtained under mild conditions.

During attempts to synthesize zirconium-based MOFs, we have obtained a new crystal structure of the cluster with ZrO core and formula unit [ZrO(OH)(OH)(CHCOO)(SO)]·HO. Unlike other systems, mild conditions were employed in this case; no strong acids or hydrothermal conditions were required. The molecular assembly in the crystal is characterized by strong O-H⋯O hydrogen bonds connecting neighboring molecules, allowing the formation of a three-dimensional maze of tunnels with HO molecules stabilizing the framework.

Survey of severe acute respiratory syndrome coronavirus 2 in captive and free-ranging wildlife from Spain.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), considered a zoonotic agent of wildlife origin, can infect various animal species, including wildlife in free-range and captive environments. Detecting susceptible species and potential reservoirs is crucial for preventing the transmission, spread, genetic evolution, and further emergence of viral variants that are major threats to global health. This study aimed to detect exposure or acute infection by SARS-CoV-2 in 420 animals from 40 different wildlife species, including terrestrial and aquatic mammals, from different regions of Spain during the 2020-2023 coronavirus disease 19 (COVID-19) pandemic.
