A Critical Overview of Common Foodborne Toxicants and Methods for Their Reliable Detection

open access: yesFood Frontiers, Volume 6, Issue 4, Page 1658-1700, July 2025.
ABSTRACT Food is an essential commodity for human health. However, toxicants such as mycotoxins, heavy metals, acrylamide, and pesticides can be present in food either naturally or through processing, packaging, or some anthropogenic activities. A thorough review of carefully selected studies revealed that climate change and pandemics have led to an ...

Enhancing Radiotherapy Tolerance With Papaya Seed‐Derived Nanoemulsions

open access: yesFood Science &Nutrition, Volume 13, Issue 4, April 2025.
Flavonoid‐rich Carica papaya (CP) seeds were used to develop Sunflower Oil‐based Papaya Oil (SPO) and Pure Papaya Oil (PPO), alongside their nanoemulsions (SPOE and PPOE), for potential radioprotective applications. Post‐radiation testing on HaCaT cell lines demonstrated significant enhancement in cell viability, with PPOE and SPOE achieving 75.85% and
