Abstract
This study investigated the antimicrobial activity of 405nm light-emitting diode (LED) with and without riboflavin against Listeria monocytogenes in phosphate buffered saline (PBS) and on smoked salmon at different storage temperatures and evaluated its impact on food quality. The results show that riboflavin-mediated LED illumination in PBS 25°C significantly inactivated L. monocytogenes cells by 6.2 log CFU/mL at 19.2J/cm2, while illumination alone reduced 1.9 log CFU/mL of L. monocytogenes populations at 57.6J/cm2. L. monocytogenes populations on illuminated smoked salmon decreased by 1.0-2.2 log CFU/cm2 at 1.27-2.76kJ/cm2 at 4, 12, and 25°C, regardless of the presence of riboflavin. Although illumination with and without riboflavin caused the lipid peroxidation and color change in smoked salmon, this study demonstrates the potential of a 405nm LED to preserve the smoked salmon products, reducing the risk of listeriosis.
