摘　　要：针对荞麦(F.tatarium)芽菜生产过程中微生物污染造成的烂种、烂苗和食品安全问题,该文利用微酸性电解水在荞麦芽菜浸种和发芽过程中进行喷洒,考察微酸性电解水对荞麦种子发芽特性、种子表面微生物和芽菜品质的影响。试验结果表明:荞麦种子浸种宜采用有效氯浓度(available chlorine concentration,ACC)为40mg/L、pH值为5.0的微酸性电解水,发芽过程喷洒ACC为50mg/L的微酸性电解水能有效控制荞麦芽菜表面细菌和真菌数量,增加芽菜的苗高以及还原糖、芦丁含量,对芽菜产量和干质量无影响。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.
