Some vacuum sealers offer additional features such as adjustable vacuum pressure, moist/dry food settings, pulse vacuum, or built-in storage for bags and rolls. If you need specific features for your vacuum sealing needs, be sure to check the specifications of different models.

Pump Power:

The power of the vacuum pump determines the suction strength of the machine. Measure the pump power in cubic feet per minute (CFM) or liters per minute (LPM). Higher pump power means faster and more thorough vacuuming.

Other Considerations:

Consider factors such as durability, ease of use, warranty, and availability of accessories when making your selection.

Preparing Food for Vacuum Sealing

Freezing Food

Before vacuum sealing food for freezing, it’s crucial to pre-freeze it. This helps maintain the food’s shape and prevents it from getting crushed when vacuum-sealed. Simply place the food on a baking sheet and freeze it until it’s solid.

Preparing Vegetables

Vegetables can release excess moisture during vacuum sealing, which can lead to freezer burn. To prevent this, blanch vegetables before vacuum sealing. Blanching involves boiling or steaming the vegetables briefly, which stops enzyme activity and helps retain their color and texture.

Marinate or Season Food

Marinate or season your food before vacuum sealing to enhance its flavor. You can use liquid marinades, dry rubs, or herb blends to infuse your food with delicious flavors. If using a liquid marinade, make sure to pat the food dry before vacuum sealing to avoid excess moisture.

Remove Bones and Fat

When vacuum sealing meat, it’s advisable to remove bones and trim excess fat. Bones can puncture the vacuum seal, leading to air leaks, while excess fat can spoil faster.

Moisture Control

Some foods, like raw meat or fish, may release moisture during vacuum sealing. To prevent this, use paper towels or absorbent pads to blot away excess moisture before sealing.

Liquid Foods

When sealing liquid foods, leave some headspace (about 2 inches) in the bag to allow for expansion during freezing. This will prevent the bag from bursting.
