Ripening and rot: How ripening processes influence disease susceptibility in fleshy fruits

open access: yesJournal of Integrative Plant Biology, Volume 66, Issue 9, Page 1831-1863, September 2024.
This review summarizes the physiological and molecular mechanisms underlying the interplay between fruit ripening and susceptibility/resistance to microbial pathogens and considers strategies for improving fruit quality, with tomato as a model for fleshy fruit‐pathogen interactions, and relevant information from many other plant species.

Does Daucus carota L. leaf provide a high potential as a source of bioactive constituents: A case study about the influences of process/storage conditions

open access: yesFood Science &Nutrition, Volume 12, Issue 8, Page 5882-5889, August 2024.
Focused on the valorization of carrot leaves, Daucus carota L. because of their high amount of ascorbic acid (AA), phenolic compounds, and the related antioxidant activity. Carrot leave is a promising source of functional constituents, including vitamin C. MW‐IR technique has been demonstrated as a superior method for drying carrot leaves.

Effect of high-pressure treatment on polyphenoloxidase activity of the Agaricus Bisporus Mushroom

open access: yes, 2002
High pressure treatments (100-500 Mpa/4 °C/10 min) were carried out on freshly sliced mushrooms ( Agaricus bisporus ) and on liquid extract. Pressure above 200 MPa led to respiratory activity loss, significant enzymatic browning and polyphenoloxidase ...
