Radish microgreens constitute a good source of bioactive compounds; however, they are very delicate
and have a short shelf life. In this study, we investigated the impact of light exposure and modified atmosphere
packaging on sensorial quality, bioactive compound concentrations and antioxidant capacity of
radish microgreens during storage. Results showed that light exposure during storage increased the
amount of ascorbic acid and had no effect on a-tocopherol or total phenolic concentrations. Dark storage
resulted in higher hydroxyl radical scavenging capacity and carotenoid retention. No significant differences
were found for relative 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity between
light and dark treatments. Radish microgreens in bags of 29.5 pmol s1 m2 Pa1 oxygen transmission
rate (OTR) maintained better quality than those within laser microperforated bags. In conclusion, light
exposure accelerated deterioration of radish microgreens, while dark storage maintained quality; and
application of OTR bags was beneficial in extending shelf life.
