Abstract
An electrolyzed solution is the one generated by electrolyzing a solution containing dissolved electrolytes. Pungency is the most important component contributing to the quality of radish (Raphanus sativus L.) sprouts. The pungency of radish sprouts depends on the 4-methylthio-3-butenyl isothiocyanate (MTB-ITC) . This study was conducted to determine the effects of electrolyzed alkaline solutions on the pungency of radish sprouts with different electrolytes and strengths. The pungency was evaluated by the analysis of MTB-ITC content and the score of sensory evaluation. The MTB-ITC content of plants was observed to be lower in solutions of strength 1/1 and 1/2 than in that of strength 1/5 among KCl electrolyzed alkaline solutions. That of plants was observed to be the lowest in KCl electrolyzed alkaline solution, followed by commercial sea salt one, and the highest in NaCl one among solutions electrolyzed with different electrolytes. The scores of the sensory evaluations were similar to the results of the MTB-ITC contents.
