[이데일리 김영환 기자] Seoul Semiconductor (046890), a global optical semiconductor company, confirmed experimental results showing that when cultivating plants with natural light, it can promote stable growth and increase in effective nutrient content like plants grown in nature. Nutrient analyzer in its own bio (BIO) laboratory ( Above) and human cell reaction tester (below), Seoul Semiconductor experimental farm testing plant growth and nutrients according to lighting (Photo = Seoul Semiconductor) Seoul Semiconductor said that when lettuce was grown using natural SunLike LED lighting, It was announced on the 18th that experimental results showed that lettuce yield increased compared to white LED lighting. Antioxidants chlorogenic acid and chicoric acid, which are important nutrients, increased by more than 30%.
This comparative experiment was conducted by installing lights equipped with regular white LEDs of the same brightness and Sunlike LEDs similar to the natural light spectrum, and then comparing the yield of lettuce and the content of antioxidants chlorogenic acid and chicoric acid for two weeks. done. Chlorogenic acid and chicoric acid remove oxygen radicals in the human body, inhibit aging and inflammation, and prevent diseases such as aging, vision loss, Alzheimer’s, and arthritis.
General white LED and Sunlike LED plant growth experiment graph (Photo = Seoul Semiconductor) In this experiment, the yield of lettuce grown under Sunlike LED lighting increased slightly by 4% compared to general white LED lighting, and the antioxidant substances chlorogenic acid and chicoric acid each increased. An increase of 55% and 31% was confirmed. The result is that the closer to natural light is used, the more nutrient content in plants can be increased.
Seoul Semiconductor has been operating its own plant cultivation experiment farm for the past 10 years. We are researching the growth and nutrient changes of various plants and nuts according to various light sources, and are even measuring nutrients ourselves and conducting experiments on the effects of nutrients on cells.
