Visible spectrum LED lights applied during postharvest to tomatoes improved phenolics and carotenoids

The objective was to evaluate the effect of visible spectrum LED lighting during shelf-life on physicochemical quality and the main bioactive compounds of Kumato? cherry tomatoes. Tomatoes were stored 13 days at 5 ?C under - white (W), - blue (B), - blue + red (B + R), - green + red (G + R), and - green + far-red (G + FR) LED lights. Darkness (D) was used as control. Tomatoes under illumination showed higher weight losses and firmness decreases (30?35%). ? White lighting did not report benefits regarding the phytochemical biosynthesis. Abstract

The objective was to evaluate the effect of visible spectrum LED lighting during shelf-life on physicochemical quality and the main bioactive compounds of Kumato? cherry tomatoes. Tomatoes were stored 13 days at 5 ?C under- white (W), - blue (B), - blue + red (B + R), - green + red (G + R), and - green + far-red (G + FR) LED lights.Darkness (D) was used as control. Tomatoes under illumination showed higher weight losses and firmness decreases (30?35%). No chilling injury was observed. B + R lighting increased the carotenoid content by ?27%, while G + R and G + FR reported an increase ?30% in phenolics. B and B + R showed the highest increase in the phytochemical biosynthesis (lycopene and naringenin, as main carotenoid and flavonoid found) compared to D and W. Conclusively, illumination with B + R or B during shelf-life is recommended to enhance the main bioactive compounds. G + R and G + FR, also reported to be good elicitors of the phenolics and carotenoids biosynthesis.?
