The shelf life of fresh-cut Peruvian carrots 'Amarela de Senador Amaral', stored under three temperatures, was evaluated. The roots were peeled manually, sliced (±1 cm thick), immersed in a solution of sodium dichloroisocyanurate 100 mg L-1 during 15 minutes and packed in rigid polypropylene package (15 x 11.5 x 4.5 cm). The packages containing around 150 g of fresh cut roots were stored under 0±1ºC, 5±1ºC or 10±1ºC during 15 days. The analyses were performed every 3 days. The experimental design was completely randomized in a 3 x 6 factorial (3 storage temperature) and 6 periods of storage, with three replicates. The storage at 0ºC provided higher L* and b* values, lower a* values, lower peroxidase, polyphenoloxidase and polygalacturonase activity, pectic solubilization and respiration rate. This temperature is the most proper for the storage of the fresh-cut peruvian carrot 'Amarela de Senador Amaral'.
