Sweet sorghum (Sorghum bicolor (L.) Moench) is an attractive feedstock for fermentation but its sugars degrade quickly after harvest. The effects of SO/sub 2/ dosage and temperature on the storability of chopped Rio sweet sorghum was studied. Four SO/sub 2/ dosage levels (0, 0.5, 1.5 and 3.0% w.b.) and five storage temperatures (-16, 2, 12, 22 and 32/sup 0/C) were investigated. The samples were stored in constant temperature incubators for three months. Fermentable sugars, sample pH and initial and final SO/sub 2/ levels were determined. All three non-zero levels of SO/sub 2/ adequately preserved the chopped sweet sorghum with no significant decrease in the total fermentable sugars.
