UVC LED, ultraviolet-C light emitting diodes (275 nm); SAEW, slightly acidic electrolyzed water.
Washed in tap water equipped with UVC waterproof-LED.
Blanched at 60°C.
Mung bean seeds and sprouts (n=3) were analyzed at 0 and 4 days, respectively.
Different letters (a-e) within the same column represent significant differences by Duncan’s multiple range test (p<0.05).
ND, not detected.
