Abstract
⺠A novel kinetic matching approach is proposed to foster rapid assessment of total (endpoint) antioxidant capacity of food samples. ⺠By selecting a compound with an oxidation kinetic profile similar to that shown by sample it is not necessary to achieve endpoint conditions. ⺠The analysis time (60 to 300 min at endpoint conditions) was reduced to <10 min for F-C, CUPRAC, DPPH
- and ABTS
- + assays. ⺠The antioxidant values obtained with the kinetic matching standard were converted to a common standard, providing an universal way for expression of results.
