Abstract: According to the problems of seeds and sprouts decay and food safety caused by microbial contamination in the production of buckwheat sprouts, weakly acidic electrolyzed water (SAEW) was applied in seed soaking and spaying in sprouts production. The effects of SAEW treatments on the properties of seeds germination, inhibition of microorganism and the quality of seed sprouts were determined. The results indicated that it was appropriate for buckwheat seeds to be soaked by SAEW with available chlorine concentration (ACC) of 40 mg/L and pH value of 5.0. Spraying SAEW with an ACC of 50 mg/L for buckwheat sprouts could reduce the population of bacteria and fungus on the sprouts and increase the height of buckwheat sprouts, reducing sugar content and rutin content, while had no negative effect on yield and dry weight of buckwheat sprouts.
