Spectral composition from led lighting during storage affects nutraceuticals and safety attributes of fresh-cut red chard (Beta vulgaris) and rocket (Diplotaxis tenuifolia) leaves

The main objective of this study was to evaluate the physiological and quality changes fresh-cut red chard (Beta vulgaris) rocket (Diplotaxis tenuifolia) leaves illuminated during storage with monochromatic light emitting diode (LED) lamps, featuring different spectral component (red, green, yellow, white, blue far-red) same intensity (35 μmol m−2 s-1). As control, in darkness assayed. Biomass, colorimetric microbiological were determined up 10 d at 5 °C. In addition, total antioxidant activity bioactive compounds along shelf-life also monitored. Microbial counts reduced by yellow chard, green rocket. Green white enabled preserve indexes chlorophylls content mostly and, eventually, increasing carotenoids chard. Total capacity phenols stimulated response or application for both species. On other hand, LED supply increased weight losses as compared darkness, although more limitedly far light. provides solid ground further exploration on how lighting treatment may foster product qualitative properties, suggesting that wavebands alternatively enhance properties reduce risks.
