Pulsed Light Technology in Food Safety and Preservation: Principles, Applications, and Future Directions

Food Chemistry International, EarlyView.
Pulsed light technology uses short high‐intensity broad‐spectrum flashes (200–1100 nm) to inactivate microbes via DNA damage. It preserves food quality, extends shelf life, and works on liquids, meats, and produce, often combined with other hurdles for enhanced efficacy.

Assessment of faecal calprotectin in neonatal calf diarrhoea using a human ELISA kit: Associations with faecal score and serum biochemical markers

Veterinary Record Open, Volume 13, Issue 2, December 2026.
Abstract Background Diarrhoea in newborn calves, which occurs in the first month of life and is caused by various pathogens, poses a significant threat to livestock industries. Therefore, timely diagnosis of enteritis in calves can be advantageous. Objective This study aimed to determine the efficacy of faecal calprotectin as a biomarker indicating ...
