Salt‐induced nutritional and metabolic shifts in halophytes: implications for food security

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Plant species vary in their response to salinity: some crops show a degree of salt tolerance, while halophytes – whether wild or cultivated – are characterized by a high capacity to thrive under saline conditions. Halophytes are considered a source of valuable secondary metabolites with potential economic value, yet they might also produce ...

Punicalagin‐enriched edible coatings from revalorized pomegranate peels for quality enhancement of fresh‐cut celery

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Pomegranate peel is a rich source of phenolics, particularly punicalagin, but its valorization for fresh produce preservation requires stabilization. This study aimed to develop and evaluate freeze‐dried encapsulates of pomegranate peel extracts as ingredients in edible coatings for fresh‐cut celery. Pomegranate peels were extracted
