Quick Answer
Glass jars offer a non-reactive storage solution for dehydrated foods, preventing moisture and flavor transfer that can affect their quality and shelf life.
Non-Reactive and Airtight Containment
Glass jars provide a non-reactive environment that won’t leach chemicals or impart flavors into dehydrated foods. This is particularly important when storing foods high in acidity or fat, such as citrus or nuts. Look for jars with a tight-fitting lid, a minimum thickness of 3.5 mm, and a glass type that’s borosilicate or soda-lime.
Moisture and Oxygen Protection
Properly sealed glass jars can effectively lock in moisture and prevent it from entering the jar. This is crucial for storing dehydrated foods, as excess moisture can cause spoilage, mold, or even pest infestation. When storing high-moisture foods, consider using a 1/4 teaspoon of silica gel per jar to absorb any remaining moisture, and ensure the jar is sealed tightly with a vacuum sealer or airtight lid.
