Abstract: Reduction and control of browning in Dangshan pear juice concentrate(PJC) by ion exchange and absorption technologies were studied. 20 °Brix Dangshan pear juice was treated with FPC-21 cation exchange resin and XAD-16 adsorption resin sequentially, and then concentrated to 70 °Brix, browning index(A₄₄₀) and other characteristics were measured during storage. Results show that treating the pear juice with FPC-21 resin can reduced pH value, formol index and browning index. Reduction of pH value enhence the decolor ability of XAD-16 resin on pear juice. Reduction of pH value and formol index can control the browning rate of PJC during storage. 20 °Brix pear juice was treated with FPC-21 resin to reduce the pH value to 4.05, then treated with XAD-16 resin to rise color value(T₄₄₀) up to 85%, and concentrated to 70 °Brix. The color value of PJC is over 45% after storing at 37℃ for 35 d, which can meet the export regulation.
