NOTE: Sulfuring does NOT prevent insect infestations, pack dried sulfur treated product immediately just as you would unsulfured fruit.
Do not store sulfur treated fruit in containers with metal lids unless a cellophane or polyethylene sheet is placed under the lid. Sulfur fumes from the fruit will react with unprotected metal.
Store fruit in dry, insect-proof containers such as home canning jars with well-fitting lids. Coffee cans may be used if the dried fruits are first placed in a plastic bag. Fruits should be packed into the container as tightly as possible without crushing. Storing fruits in tightly sealed, plastic bags will help keep the original fruit color.
