SMB must be used as a source of SO2. SO2 is commonly used here as a preservative and to maintain color and prevent darkening of such things as dried apricots. You can taste and smell it. You can buy dried apricots without SO2 in health food stores, but they will be black -tastier but not as appetizing. It must prevent potatoes from oxidizing and blackening in the same way.
