Abstract

We measured the antioxidant activities of Oak mushroom (Lentinula edodes) in browned sawdust medium under conditions of varying LED sources and amounts of light. Consequently, exposure to 200Lx blue LED resulted in highly efficient browning; the most efficient browning was shown at 200Lx, regardless of the type of luminous source. We identified that quantities obtained with the blue luminous source increased compared to those in other treatment plots. The DPPH radical scavenging test conducted to examine antioxidant activity revealed that the red luminous source caused high radical scavenging compared to efficient browning. The fruiting body for Nongjin-go, as a treatment plot with the highest scavenging, under a 400Lx red luminous source was $34.3{\pm}1.80%$ and that for 'Sanjo 701' at a 300lx red luminous source was $32.99{\pm}1.58%$. The polyphenol content, reported to be correlated with DPPH radial scavenging, showed no similar correlation in the 'Nongjin-go' variety. By contrast, 'Sanjo 701' showed a similar association.
