negligible at 49 C. but increases with decreasing temperature. At 24’ C. the rate of sulfite disappearance in air is approximately twice the rate for corresponding samples in nitrogen. Little change in the sulfite disappearance rate in dehydrated carrot is caused by varying the blanching time from 2 to 8 minutes, by sulfite application during or after blanching, or by sulfite application by spray or as gas. However, a marked d e crease in the sulfite disappearance rate is caused by prolonged soaking in water before dehydration. On the basis of the generalizations presented, it is feasible to estimate the life expectancy of the sulfite in other samples of dehydrated sulfited vegetables. ACKNOWLEDGMENT
