What causes mold to form on foods during the drying process?
Causes and Suggestions: Incomplete drying will result in mold formation. Prevent this from occurring by testing several pieces for dryness. Foods that have not been checked for moisture will cause mold to form. Check food containers within one week for the presence of moisture. Dry the food again at 140 °F until moisture disappears. Containers that are not airtight will allow moisture to set in and mold to form. Prevent this by always using airtight storage containers.
