Abstract

The effects of slightly acidic electrolyzed water (SAEW), produced from different electrolytes (NaCl and HCl solution) with available chlorine concentrations (ACC) at 35 and 70 mg/L, for the production of soybean sprouts were investigated. Soybean treated by tap water was used as control. The counts of total bacteria, coliform, yeast and mold on the soybean seeds and sprouts were detected daily during seed germination. The rates of water absorption and germination was determined after 12 h soaking. Upon harvested, the length, stem diameter and fresh weight of the sprouts were determined, along with their vitamin C and flavonoids content. The results showed that, in comparison to the tap water-treated soybean sprouts, SAEW treatment could significantly reduce the count of natural microbiota in seeds and sprouts during soybean germination. The SAEW treatment had no adverse effect on the water absorption rate and germination rate of soybean seeds. In addition, short sprout length with thick stem contributed to the yield of sprouts with no negative effect by SAEW treatment. There were significant differences in the content of vitamin C and flavonoids in soybean sprouts treated with different SAEW electrolyzed by NaCl or HCl solution. Higher content of vitamin C and flavonoids was obtained in the sprouts treated with SAEW from electrolysis of HCl solution. So, SAEW treatment could reduce the count of microbiota effectively and had no adverse effect on seed germination and the yield of soybean sprouts, and even improved the nutrition quality. Therefore, SAEW produced from HCl solution could be a promising application in improving the production of soybean sprouts.
