Abstract

Background: This work investigates the morphological and compositional changes of carrots sprouts during 17 days at 20 °C. Methods: Growing conditions were 7 days in darkness (dD) followed by 3, 7, or 10 days of a 16 h light/8 h darkness photoperiod (dP). Light stimuli used were fluorescent light (Fl), Blue+Red (B+R), Blue+Red+Far-Red (B+R+FR) Light-Emitting Diodes—LEDs- and darkness as control. Results: Results showed that lighting conditions improved the total antioxidant activity and increased the bioactive compounds compared to darkness treatment. However, hypocotyl and sprout length were increased under darkness conditions. Both LEDs treatments (B+R and B+R+FR) increased the phenolic content (phenolic acids and rutin) by 45% and 65% compared to darkness and by 32% regarding Fl. Moreover, a similar trend was observed in the carotenoids content under B+R LEDs, but not when FR was added. Conclusions: Our results suggest that LED lighting during carrot sprouting improved the synthesis of health-promoting compounds.
