Ultraviolet LEDs Enhance Lettuce Nutrients
Sientists have found that applying supplemental ultraviolet-B radiation to red-leaf lettuce increases the production of polyphenolic compounds and possibly the storage lifetime of the chemicals.
Can exposing our food to low-energy light-emitting diodes (LEDs) improve its nutritional quality? A new report from the U.S. Department of Agriculture (USDA) says yes. Greenhouse cultivation allows high-quality, local produce all year long, but most greenhouse coverings filter out the short ultraviolet wavelengths from the solar spectrum, decreasing the synthesis and accumulation of some nutrients.
