Abstract

As consumers interest in microgreens is increasing worldwide, the production of leafy microgreens uisng different LED lights was investigated in this study. The experiment was carried out to evaluate the effects of different LED lights on the composition and vitamin C contents of buckwheat microgreens. Physicochemical properties of buckwheat microgreens grown under different lights (red, blue, and white) and control exposed to a dark room were investigated. Moisture contents of buckwheat microgreens were 95.65% under white light (WL), 95.75% under blue light (BL), 90.77% under red light (RL), and 89.71% under dark room (DR). Crude ash contents of buckwheat microgreens grown under WL, DR, RL, and BL were 0.39%, 0.39%, 0.31%, and 0.37%, respectively. Crude protein contents of buckwheat microgreens grown under DR, RL, WL, and BL were 7.12%, 7.81%, 1.60%, and 2.40%, respectively. Crude fat contents of buckwheat microgreens grown under DR, BL, RL, and WL were 1.12%, 0.54%, 0.35%, and 0.22%, respectively. 캛rix was the highest in microgreens grown under BL and RL and the lowest in buds grown under DR. Vitamin C content was the highest in buds grown under WL and the lowest in buds grown under BL. Total chlorophyll content was the highest in microgreens grown under RL and the lowest in buds grown under WL. For mineral content measurement of buckwheat microgreens, Ca, K, Mg, and P contents were high whereas B, Cu, and Zn contents were not detected. The mineral contents of buckwheat microgreens according to each color of light showed significant differences. These results demonstrated that treatment of different colored LED lights during cultivation was able to increase vitamin C content up to affecting the nutritional value of buckwheat microgreens.
