Hand harvested Meeker red raspberries were held at 4/sup 0/, 14/sup 0/, and 25/sup 0/C for up to 12 days using two types of sulfur dioxide generating pads. Visual mold rating were lower for fruits held with either SO/sub 2/ generator, but Howard Mold Count did not differ between the generators and the control fruits. Fruits stored with the generators were brighter and redder in color than controls when stored at 4/sup 0/C. Irregular bleaching of anthocyanins from drupelets occurred when fruits were stored at 14/sup 0/C or higher. Use of SO/sub 2/ generators is not recommended for fresh market fruit or nonheat treated processing fruit due to the bleaching and due to SO/sub 2/ residues in the fruit.
