Are there certain foods that cannot be stored in GardaPack® bags?
GardaPack® vacuum seal bags are engineered for versatile, high-performance food preservation. While they are suitable for a vast majority of food items, certain biological processes—such as gas emission or high moisture content—require specific handling or alternative storage methods.
To ensure the best results and maintain food safety, please review the following considerations:
1. Fresh Mushrooms
Mushrooms have a high moisture content and a unique respiratory rate. Vacuum sealing creates an environment that can accelerate spoilage for fresh mushrooms. We recommend storing them in a breathable container or a paper bag in the refrigerator.
2. Garlic and Raw Onions
These aromatics naturally release gases even after being harvested. In a vacuum-sealed environment, these gases can expand the bag and cause the food to spoil more quickly. For optimal shelf life, store garlic and onions in a cool, dry, well-ventilated space.
3. Cruciferous Vegetables
Vegetables such as broccoli, cauliflower, cabbage, and Brussels sprouts emit gases when stored raw.
- Pro Tip: To safely vacuum seal these items, you must blanch them first (briefly boil, then plunge into ice water). Once blanched and dried, they can be vacuum-sealed and frozen for long-term storage.
4. Delicate Leafy Greens
The pressure of a vacuum seal can crush the cellular structure of delicate greens like spinach or arugula, leading to bruising and wilting. For these items, we recommend airtight containers or bags with slight ventilation to maintain crispness.
5. Soft or High-Moisture Fruits
Extremely juicy fruits, such as watermelon or very ripe citrus, can release excessive liquid during the vacuum process. This moisture may interfere with achieving a secure heat seal.
- Pro Tip: For best results, pre-freeze soft fruits on a baking sheet for 1–2 hours before vacuum sealing them for long-term freezer storage.
6. Fermenting Foods & Soft Cheeses
Foods that are actively fermenting or contain live cultures (like certain soft cheeses or unpasteurized ferments) produce gases. These gases will eventually break the vacuum seal. Soft cheeses like Brie or Camembert are best stored in their original packaging or cheese paper.
7. Hot Foods
Never attempt to vacuum seal food while it is still steaming. The heat can compromise the integrity of the bag’s seal and create a vacuum that is less effective as the air cools. Always allow cooked foods to reach room temperature before sealing.
