AbstractHypsizygus marmoreus (Peck.), also called bunashimeji and hon-shimej, is successfully cultivated and commercially available in Taiwan. Illumination with a Cold Cathode Fluorescent Lamp (CCFLS) and Light Emitting-Diodes (LEDs) has lately become a more available technology and a more economic and energetically efficient way for light treatment on mushrooms. In this study, effects of illumination light source and wavelengths on the fruit body’s production and content of nutritional qualities and antioxidant properties were investigated. The Biological Efficiency (BE) of the CCFLs lights was the highest at 94.71%. Based on the fresh weight (fw), CCFLs, LEDS 2W1B (180) and LEDS 2W1B (240) light cultivation contained higher amount of crude ash, crude protein, crude fat and crude fiber, whereas the LEDS 3W (180) contained higher amount of carbohydrate. For all samples, the content of polysaccharide ranged from 0.30 to 0.36 g/100 g fw. The total hydrolysis amino acid content in four light cultivation of H. marmoreus ranged from 1477.22 to 1709.33 mg/100 g fw and were in the descending order of LEDS 2W1B (180) > LEDS 2W1B (240) ~ CCFL > LEDS 3W (180). EC50 values were 4.54-6.67 mg/mL, 2.78-2.81 mg/mL, and 0.32-0.34 mg/mL for reducing power, scavenging ability on DPPH radicals and chelating ability on ferrous ions, respectively. The major antioxidant components found in ethanolic extracts were total phenols (9.39 to 11.50 mg/g). Based on the results obtained, light of different wavelengths and sources had little influence on nutritional qualities and antioxidant properties of H. marmoreus fruit bodies.
