Abstract

        No study has been reported about magnetic fields effects on properties of agricultural products in the postharvest stage. In this research a static and dynamic magnetic fields apparatus was fabricated and then the field effects with magnetic flux densities of 2784 and 8240 G and magnetic time of 1 and 12 h on total soluble solids, pH, total antioxidant capacity and total phenolic compounds of pomegranate arils were investigated. Between chemical indicators, the effect of magnetic field on the total antioxidant capacity of pomegranate arils was significant. Dynamic magnetic field with flux density of 8240 G and time of 1 h caused %13/32 increase in antioxidant capacity. But magnetic time of 12 h caused %11/08 decrease in antioxidant capacity. Finally the effect of dynamic magnetic field was more than static magnetic field and magnetic flux density of 8240 G was more than 2784 G.
