Abstract:To investigate the effects of physicochemical indicators of electrolyzed water and germination conditions on the content of phenolic acids in buckwheat sprouts，the'Jinqiao No.6'variety was used as the raw material. Single-factor experiments were conducted using the pH value of electrolyzed water，effective chlorine concentration of electrolyzed water，germination temperature，and germination time as the factors，with the total content of phenolic acids as the response value. On this basis，response surface analysis was employed to optimize the germination conditions of buckwheat. The results showed that treating buckwheat seeds with electrolyzed water at a pH value of 5.90 and an effective chlorine concentration of 19.50 mg/L，followed by cultivation at 26 ℃for 6.5 d，resulted in a total content of phenolic acids in buckwheat sprouts of 15.06 mg/g. This represented a 74.10% increase compared to the tap water treatment. Among the 11 detected phenolic acids，chlorogenic acid had the highest content（9.03 mg/g）. The electrolyzed water treatment group exhibited significantly higher levels of vanillic acid，salicylic acid，syringic acid，and chlorogenic acid in buckwheat sprouts compared to the tap water treatment group（P＜0.05）. However，the hydroxybenzoic acid and caffeic acid levels were significantly lower in the electrolyzed water treatment group than in the tap water treatment group（P＜0.05）.There were no significant differences in the content of the remaining major phenolic acids between the electrolyzed water treatment group and the tap water treatment group（P＞0.05）.
