“…19,20 Some studies have shown that the B–Z oscillatory reaction has the advantages of being rapid, not limiting the physical properties of the sample, not requiring isolation and purification, and being easy to analyze and characterize. 21–23 There are fewer studies on the use of electrochemical oscillatory reactions for food quality, so in this paper, we use electrochemistry to conduct a new exploration of rice and paddy grains to investigate the effect of chemical composition in the samples on the electrochemical system.…”
