470Tα-MOFThe apparent Km of Tα-MOF is measured 3.180 mM and 0.0109 µM for TMB and H2O2, respectively. In this study, the LOD values for Ferulic acid, Tannic acid, and Chlorogenic acid were 0.19, 0.06, and 0.11, respectively. The RAC value obtained for tannic acid, orange juice, and lemon juice was 4.79, 3.37, and 3.53, respectively.Ascorbic acid (AA)Color0-35μM0.39μMRelatively, the extracts lead to a discoloring tendency in the order of Lemon Juice > Orange Juice > Eucalyptus > Cichorium intybus > Thymes > Morus
