Tomato fruit possess high lycopene concentrations, which increases after reaching the breaker stage of ripeness.
Light emitting diode (LED) systems have emerged as a clean and efficient artificial lighting technique for use in
horticulture. The objective of this research was to examine the effect of LEDs on postharvest and lycopene
quality parameters. The effects on quality parameters were significantly different depending on the tomato fruit
cultivar. The commercial and organoleptic quality parameters most affected were firmness and titratable acidity.
The lycopene concentration in all tomato cultivars increased between 30% and 60% when they were exposed to
LED light compared with dark-exposed fruit. One hour of LED light exposure per day during the postharvest
phase of fruit increased commercial and organoleptic parameters, and increased the lycopene concentration.
Fruit exposed to LED light with a high red:far red (R:FR) light ratio had increased firmness compared with those...
