摘要

该研究将不同电解质(NaCl和HCl)电解生成的有效氯浓度分别为35和70 mg/L的微酸性电解水(slightly acidic electrolyzed water, SAEW)应用于黄豆发芽过程,以自来水为对照,考察SAEW的杀菌效果以及对黄豆芽的发芽特性、生长指标和营养物质含量等方面的影响。结果表明,与自来水相比,SAEW处理的黄豆和黄豆芽表面的菌落总数、大肠菌群、霉菌和酵母总数均明显下降;SAEW处理对黄豆的吸水率、发芽率和产量无负面影响(SAEW处理组芽长短但茎粗大,鲜重无明显变化);SAEW处理组黄豆芽中VC和类黄酮含量随电解质不同有所差异(电解HCl生成的SAEW处理组VC和类黄酮含量显著高于电解NaCl生成的SAEW处理组)。鉴于上述研究结果,可将SAEW(以HCl为电解质)用于黄豆发芽过程,保障黄豆芽的微生物安全和营养特性。

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.

Key words： slightly acidic electrolyzed water; soybean sprouts; decontamination; germination quality; growth quality; nutrition
