The effects of $SO_2$ treated pads ($SO_2$ 0, 0.5, 1, and 2 g/kg) on the quality of dried persimmons slices were investigated. The $SO_2$ treated pads for storage did not affect to weight, moisture loss rate, and soluble solid contents of dried persimmons slices. The color change after storage for 12 weeks was the highest (value = 3.5) in control ($SO_2$ 0 g/kg), whereas that was the lowest (value = 2.0) under $SO_2$ 2 g/kg condition. When we measured the browning degree after 12 weeks, they showed O.D. 0.24, 0.22, 0.20, and 1.7 in serial dilution treated pads with $SO_2$ 0, 0.5, 1, and 2 g/kg, respectively. The decaying rate was the highest (7.0%) in control after 12 weeks storage, whereas it did not show any spoilage in $SO_2$ 1 g/kg and 2 g/kg treated condition for whole storage period. The concentration of residual $SO_2$ in dried persimmons slices was detected within a safe range of 20.3~40.3 ppm. Therefore, the shelf-life of dried persimmons slices was lengthened in $SO_2$ treated pads (especially in $SO_2$ 2 g/kg) for inhibiting of browning and decaying.
