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.
