摘要: 以苦荞为原料,将不同有效氯浓度(available chlorine concentration,ACC)的微酸性电解水(slightly acidic electrolyzed water,SAEW)应用于芽苗菜生产,研究其对苦荞芽活性成分及其抗氧化能力的影响。结果表明:SAEW处理组苦荞芽活性成分含量相比对照组有所增加,ACC为20 mg/L的SAEW处理的苦荞芽总酚、总黄酮及芦丁含量相比自来水对照组分别提升了28.69%、26.19%和29.08%。SAEW处理萌发的苦荞芽在生长7 d内苯丙氨酸解氨酶比活力均高于自来水对照组。苦荞芽的抗氧化活性物质含量与其抗氧化能力间呈显著正相关。

Abstract: The bioactive components and antioxidant activity of tartary buckwheat sprouts treated with slightly acidic electrolyzed water (SAEW) with different available chlorine concentrations (ACC) were examined in this study. The results demonstrated that the content of bioactive components in buckwheat sprouts treated with SAEW was higher than that in sprouts treated with tap water (TW). The contents of total phenols, total flavonoids and rutin in sprouts treated with SAEW (pH 5.5, with 20 mg/L ACC) were increased by 28.69%, 26.19% and 29.08% respectively, as compared with those in the control group. The phenylalanine ammonia-lyase (PAL) activity in SAEW-treated sprouts was higher than that in the control sample throughout the whole period of germination. The contents of total phenolics, total flavonoids and rutin showed a significant correlation with values of the antioxidant capacity assayed by 3 different methods.
