Yes, you can vacuum pack chopped pumpkin for freezing. Vacuum packing helps prevent freezer burn and extends the pumpkin's shelf life.
Vacuum packing is an excellent method for preserving chopped pumpkin in the freezer. Here's a step-by-step guide:
Prepare the Pumpkin: Wash, peel, and chop the pumpkin into uniform pieces. Smaller pieces will freeze and thaw more quickly and evenly.
Blanching (Recommended): Blanching helps to preserve the pumpkin's color, texture, and nutrients. Submerge the chopped pumpkin in boiling water for 2-3 minutes. Then, immediately transfer it to an ice bath to stop the cooking process. Drain thoroughly.
Dry the Pumpkin: Pat the blanched pumpkin pieces completely dry with paper towels. This is crucial because excess moisture can lead to ice crystal formation and freezer burn, even with vacuum sealing.
Portion and Pack: Divide the pumpkin into portions suitable for your needs. Place the portions into vacuum seal bags, leaving enough space at the top for the sealing process.
Vacuum Seal: Use a vacuum sealer to remove the air from the bags and seal them tightly. Ensure the seal is strong and airtight.
Freeze: Label the bags with the date and contents, and place them in the freezer. Lay them flat initially for easier stacking once frozen.
To prevent the pumpkin pieces from sticking together during freezing, consider flash-freezing them before vacuum sealing. Spread the chopped pumpkin in a single layer on a baking sheet lined with parchment paper and freeze for about an hour. Then, transfer the frozen pieces to the vacuum seal bags and proceed with sealing. This will result in individually frozen pieces that are easier to use later.
