The Impact of Pyropheophytin a (PPP) and 1,2‐Diacylglycerols (DAGs) on Extra Virgin Olive Oil Quality and Shelf Life

Journal of the American Oil Chemists' Society, Volume 102, Issue 8, Page 1185-1200, August 2025.
ABSTRACT The quality and shelf life of extra virgin olive oil (EVOO) are pivotal to its marketability and consumer satisfaction. This study evaluated how pyropheophytin a (PPP) and 1,2‐diacylglycerols (DAGs) changed for different varieties of EVOO over a 24‐month storage period under varying temperature conditions (16°C, 18°C, and 20°C).

Oilseed‐based metabolic engineering of astaxanthin and related ketocarotenoids using a plant‐derived pathway: Lab‐to‐field‐to‐application

Plant Biotechnology Journal, Volume 23, Issue 8, Page 3451-3464, August 2025.
Summary Ketocarotenoids, including astaxanthin, are red lipophilic pigments derived from the oxygenation of β‐carotene ionone rings. These carotenoids have exceptional antioxidant capacity and high commercial value as natural pigments, especially for aquaculture feedstocks to confer red flesh colour to salmon and shrimp.

A novel detection method for lipid stability in almond leads to the discovery of marker-trait associations

Fruit Research
Nut kernel rancidity is a significant postharvest concern because it compromises flavor and decreases shelf-life. Roasting of nut kernels changes the chemical structure and leaves the kernel more susceptible to rancidity.
