Video vacuum sealing is a method of removing air from a bag using a vacuum sealer, often while watching a video tutorial. It’s a practical technique for preserving food, saving space, and preventing freezer burn. This guide walks you through the process, from choosing the right bags to sealing and storing your items, so you can get the most out of your vacuum sealer.
Ingredients
- 1 vacuum sealer machine (e.g., FoodSaver, Anova, or similar)
- Vacuum sealer bags or rolls (compatible with your machine, typically 11 in / 28 cm wide)
- Food to seal (e.g., raw meat, vegetables, dry goods, or leftovers)
- Paper towels (for drying moisture)
- Optional: freezer-safe marker for labeling
Instructions
- Prepare your food: If sealing raw meat, pat it dry with paper towels to remove excess moisture. This helps the seal adhere properly and prevents ice crystals from forming. For vegetables, blanch them first (boil for 2-3 minutes, then ice bath) to stop enzyme activity and preserve color and texture.
- Cut the bag to size: If using a roll, cut a piece about 2-3 inches (5-8 cm) longer than the food you’re sealing. If using pre-made bags, skip this step.
- Seal one end (if using a roll): Place one end of the cut roll onto the sealing strip of your vacuum sealer, close the lid, and press the “Seal� button (not “Vacuum Seal�). Wait until the indicator light turns off. This creates the bottom of your bag.
- Place the food inside: Open the sealed bag and place your food inside, leaving at least 2 inches (5 cm) of empty space at the open end. This space is needed for the vacuum to pull and for the seal to form properly.
- Position the bag in the sealer: Place the open end of the bag onto the vacuum channel, making sure it lies flat and is centered. Close the lid and lock it (some models have a latch).
- Start the vacuum and seal: Press the “Vacuum Seal� button. The machine will suck out the air and then automatically seal the bag. Wait for the indicator light to turn off or the beep to sound, indicating the cycle is complete.
- Check the seal: Open the lid and remove the bag. Press gently on the seal area to ensure it’s fully fused. If there are any gaps or wrinkles, cut the bag open and re-seal with a fresh bag.
- Label and store: Write the contents and date on the bag with a marker. Refrigerate or freeze immediately. For raw meat, place the sealed bag in the refrigerator if using within 1-2 days, or in the freezer for longer storage.
Tips
- Don’t overfill: Leave enough headspace (at least 2 inches) so the vacuum can pull the bag tight without sucking food into the seal. Overfilling can cause the seal to fail.
- Dry food is key: For moist foods like raw chicken or fish, pat them dry before sealing. If you’re sealing liquids like soups, freeze them first in a tray or use the “moist� setting if your machine has one, and consider using a special liquid-safe bag or container.
- Use the right bags: Only use bags designed for vacuum sealing. Regular zipper bags won’t work because they can’t withstand the vacuum pressure and may tear. Check your machine’s manual for compatible brands.
- Seal in portions: For meat, seal individual portions or meal-sized amounts. This allows you to thaw only what you need and reduces waste.
Serving Suggestions
Vacuum-sealed food is not served directly; it’s a storage method. However, you can use vacuum-sealed items for sous-vide cooking, which yields incredibly tender and flavorful results. For example, seal a seasoned steak, then cook it in a water bath at 130°F (54°C) for 1 hour, then sear it in a hot pan. Vacuum-sealed vegetables can be steamed in the bag, and dry goods like beans or coffee stay fresh longer.
Variations
- Dry vs. Moist: Some vacuum sealers have a “Dry� and “Moist� setting. Use “Moist� for foods with high liquid content, like marinated meats or stews, to prevent liquid from being sucked into the machine.
- Container sealing: Many machines come with an accessory hose to seal special containers or mason jars. This is great for storing dry goods like cereal, nuts, or even leftover soup, and it uses less plastic.
- Marinating: Vacuum sealing can speed up marinating by pulling the marinade into the meat. Place meat and marinade in a bag, seal, and refrigerate for 30 minutes to 1 hour for a quick flavor boost.
Storage and Reheating
Vacuum-sealed raw meat can be refrigerated for 1-2 days before cooking, or frozen for up to 6-12 months depending on the type (consult USDA guidelines for specific times). Cooked leftovers can be refrigerated for 3-4 days. To reheat, you can place the sealed bag in simmering water (not boiling) until heated through, or open the bag and microwave the contents. Always reheat leftovers to an internal temperature of 165°F (74°C) for safety. For frozen items, thaw in the refrigerator overnight or in cold water for quicker thawing. Do not use a microwave to thaw vacuum-sealed meat, as it can cause uneven heating and compromise texture.
Frequently Asked Questions
Can I vacuum seal liquids like soup? Yes, but you need to freeze the soup first in a tray or use a liquid-safe container. If you try to vacuum seal liquid directly, it will get sucked into the machine and damage it. Freeze the soup in a bowl or ice cube tray, then transfer the frozen blocks to a vacuum bag and seal.
Why is my bag not sealing properly? This usually happens if the bag is overfilled, if there is moisture or grease on the seal area, or if the bag has wrinkles. Make sure the seal area is dry and flat, and leave enough headspace. If the problem persists, check the sealing gasket for debris or wear.
Can I reuse vacuum sealer bags? Yes, but only for dry items. Wash the bags in warm soapy water, rinse well, and let them dry completely before reusing. Do not reuse bags that held raw meat, as bacteria can linger. Also, avoid reusing bags for long-term storage, as the seal may weaken.
Does vacuum sealing kill bacteria? No, vacuum sealing does not kill bacteria. It removes oxygen, which slows the growth of aerobic bacteria, but anaerobic bacteria (like botulism) can still grow in low-oxygen environments. Always refrigerate or freeze vacuum-sealed food and follow safe food handling practices.
Can I vacuum seal bread or soft items? Yes, but they may get crushed. To prevent this, use a rigid container or freeze the bread first, then seal it. Alternatively, use the “gentle� or “pulse� setting if your machine has one, to control the vacuum strength.
Is it safe to vacuum seal raw meat and then cook it later? Yes, it’s safe as long as you refrigerate the sealed meat and cook it within 1-2 days, or freeze it. When you thaw it, do so in the refrigerator, and cook to the safe minimum internal temperature: whole cuts of beef, pork, veal, and lamb to 145°F (63°C) with a 3-minute rest; ground meat to 160°F (71°C); poultry to 165°F (74°C).
