Effect of a 7-day simulated home refrigerated storage at 4 °C on ascorbic acid (A), total phenolic (B) and carotenoid (C) contents and antioxidant capacity (FRAP (D) and DPPH (E)) of cold-pressed juices. Bars represent mean ± standard deviation (SD) of three independent replicates. For each measured value, comparisons are shown between the fresh juice and different time-points during storage of each fruit juice. An asterisk (*) above the bars indicates a significant difference at that time-point compared to the fresh juice (control) (Duncan's multiple-range test, p < 0.05) (GAE: gallic acid equivalent, TE: Trolox equivalent, E: equivalent).
