Abstract: Taking the fruits of Pruns armeniaca L. as testing material, the effect of storage temperature on post-harvest preservation quality was studied. The decay rate, weight loss, soluble solids content and titratable acid content were measured at 0, 2, 4, 6 ℃. The results showed that the quality of fruits of Pruns armeniaca L. varied remarkably with temperatures of storage. Compared with storage at 4 ℃ and 6 ℃, the storage at 0 ℃ and 2 ℃could significantly reduce the decay rate and weight loss rate of the fruit, and could maintain the preferable firmness, soluble solid content and titratable acid of the fruits during storage. The total phenol and VCwere also effectively inhibited.Thus, the antioxidation activity can be maintained in a comparably high level.
