The total antioxidant capacity (TAC) of 23 fruit juice samples was determined using the TEAC assay, and also, it was predicted by FTIR-PLS, the plot of measured and predicted values showing a good correlation (R = 0.97). Thus, FTIR spectroscopy is a promissory technique for rapid screening of TAC of fruit juices.
