Yes, ash gourd should be wrapped in plastic wrap or placed in a plastic bag before storing it in the refrigerator to prevent moisture loss and maintain its freshness.
Ash gourd has a naturally long shelf life due to its thick skin. However, once cut or exposed to air, it can start to dry out and lose its quality. Wrapping the ash gourd before refrigerating helps to create a barrier against the dry air inside the refrigerator, preventing moisture from escaping. This keeps the flesh firm and prevents it from becoming spongy or developing an off-flavor. The wrapping also helps to protect the ash gourd from absorbing odors from other foods in the refrigerator. For whole, uncut ash gourds, wrapping is generally not necessary if stored in a cool, dry place. However, refrigeration, even for whole gourds, can extend their shelf life, and wrapping provides an extra layer of protection.
Before wrapping, ensure the ash gourd is dry. Excess moisture trapped inside the wrapping can promote mold growth and spoilage. Pat the cut surface dry with a clean paper towel before wrapping it tightly.
