Detection of rice freshness by chemiluminescence method
Since the measurement of peroxidase activity can be used as an important indicator to determine the freshness of rice,and peroxidase can also catalyze the chemiluminescence system of luminol-hydrogen peroxide.Chemiluminescence method,a new rice freshness detection method was established.In this paper,by optimizing the experimental conditions,the concentration of hydrogen peroxide was 5.0×10-3 mol/L,the concentration of luminol was 2.0×10-6 mol/L,pH 9.2,and the number of rice particles was 10.Under the optimal experimental conditions,we used the chemiluminescence method to measure the freshness of rice and compared it with two traditional rice freshness detection methods.The experimental results show that the correlation between them is good.This also shows that the chemiluminescence method is reliable and provides a new method for the detection of rice freshness.
