Usage |
Typical Application |
Food industry |
Sulfur dioxide is sometimes used as a preservative for dried apricots, dried figs, and other dried fruits, owing to its antimicrobial properties. As a preservative, it maintains the colorful appearance of the fruit and prevents rotting. It is also added to sulfured molasses. |
Refrigeration |
Being easily condensed and possessing a high heat of evaporation, sulfur dioxide is a candidate material for refrigerants. Prior to the development of chlorofluorocarbons, sulfur dioxide was used as a refrigerant in home refrigerators |
