本研究用电解水生产黑小麦芽,探究电解水对黑小麦发芽及生长的影响,并考察了电解水处理对黑小麦芽基本营养成分的影响,以期为电解水用于黑小麦的发芽提供科学依据。试验结果表明,电解水均可以促进黑小麦种子的萌发,其中pH值为4.55,有效氯浓度20.14 mg/L的酸性电解水处理组黑小麦发芽率比自来水对照组提高15.29%。但电解水处理组会不同程度的抑制黑小麦芽胚轴和胚根的生长,与自来水pH值相近的酸性或碱性电解水的抑制作用相对较弱。经pH值4.36~4.91,有效氯浓度10~30 mg/L的酸性电解水处理的黑小麦芽脂肪含量比自来水对照组降低27.06%~36.93%,还原糖含量降低21.84%~56.58%,总糖含量降低13.68%~27.11%,而蛋白质含量与对照组间无显著差异。因此在黑小麦芽的生产过程中,适宜在种子浸泡阶段使用电解水,而在芽苗淋浇阶段使用自来水,这样既促进了种子的萌发,也不会对黑小麦芽的生长产生抑制作用。

[Abstract]
Electrolyzed water was used to produce black wheat sprouts, and the effect of electrolyzed water on germination, growth, and basic nutrient content of black wheat sprouts was investigated to provide a scientific basis for applying electrolyzed water in black wheat sprout production. The results showed that electrolyzed water promoted the germination of black wheat sprouts, and the germination rate of black wheat seeds treated with electrolyzed water at pH 4.55 with an available chlorine concentration of 20.14 mg/L was 15.29% higher than germination rates of seeds exposed to tap water. However, electrolyzed water inhibited the growth of hypocotyls and radicles of black wheat sprouts to various extents, while the inhibitory effects of acidic or alkaline electrolyzed water with pH values similar to that of tap water was relatively weak. The fat, reducing sugar, and total sugar content of black wheat sprouts treated with acidic electrolyzed water (pH: 4.36~4.91, available chlorine concentration: 10~30 mg/L) were 27.06~36.93%, 21.84~56.58%, and 13.68~27.11% lower than sprouts exposed to tap water, respectively, while no significant differences in protein content were seen between groups. Therefore, during the production of black wheat sprouts, electrolyzed water and tap water are suitable for the soaking stage and the spraying stage, respectively, which can promote the germination and prevent inhibition of black wheat sprout growth.
