How to Choose a Vacuum Food Sealer to Preserve Food and Reduce Waste

Keeping food fresh longer and reducing waste are key goals for many. A vacuum food sealer (Vakuumiergerät) is a household tool that helps remove air from bags and seal them tightly, slowing oxidation and the growth of certain microorganisms. In this guide, we offer practical tips for choosing the right machine for your needs in Germany and Europe.

Why use a vacuum sealer?
• Extend food shelf life: Reducing oxygen limits fat spoilage and the growth of aerobic bacteria.
• Reduce waste: You can buy larger quantities during sales and store them safely.
• Organize the kitchen: Flat bags make it easier to arrange in the fridge or freezer.
• Faster marinating: Vacuum sealing speeds up the penetration of marinades into meat and vegetables.

Types of vacuum sealers
• External vacuum sealer: The most common for homes. Works with special bags or containers. Suitable for daily use.
• Chamber vacuum sealer: Places the bag inside a chamber and removes air from it. Usually stronger and faster, and suitable for liquids and soft foods. But it is larger and more expensive.
• Manual or portable machines: Small and lower priced, suitable for light tasks and travel, but suction power may be limited.
• Multi-purpose devices: Some models come with a hose for vacuum sealing containers and jars.

Features to look for
• Suction power: Varies by model. For normal home use, medium power is sufficient. If you deal with large cuts of meat or liquids, look for higher power.
• Sealing system: Double sealing bar increases seal durability. Check if sealing time is adjustable.
• Liquid mode: Some machines offer a special mode for moist foods that prevents liquid from being drawn into the pump.
• Containers and hose: If you plan to store cheese or salads, make sure the machine is compatible with vacuum containers or has a hose port.
• Ease of cleaning: Removable parts that are dishwasher-safe save time.
• Size and weight: Chamber vacuum sealers are heavy and require storage space.
• Warranty and customer service: Look for a reasonable warranty and availability of spare parts.

Considerations before buying
• Budget: Determines options. External machines are usually less expensive than chamber vacuum sealers.
• Frequency of use: If you use it daily, invest in a durable model. For occasional use, a basic model is enough.
• Type of food: Meat and fish need strong suction. Leafy vegetables may be damaged if compressed too much. Soft fruits need gentleness.
• Bag availability: Make sure suitable and affordable bags are easy to find in your area or online.
• Energy consumption: Most machines consume less energy than large kitchen appliances, but chamber vacuum sealers may consume more.

Tips for safe and effective use
• Leave an air gap in the bag before sealing to avoid drawing in liquids.
• Dry food slightly before vacuum sealing, especially marinated meat.
• Cut food into even pieces for better vacuum sealing.
• Do not vacuum seal hot foods; let them cool first.
• Use only bags designed for vacuum sealing.
• For vegetables, you can blanch quickly before vacuum sealing to preserve color and texture.
• Write the date on the bag to track storage time.
• Follow the manufacturer's instructions for cleaning the device.

Ideas to reduce food waste
• Buy in bulk during sales and divide into portions.
• Store leftovers instead of throwing them away.
• Prepare weekly meals in advance.
• Use vacuum sealing to store seasonal fruits.
• Share excess food with neighbors or donate it if possible.

Frequently asked questions

Can regular bags be used with a vacuum sealer?
No, it is always recommended to use bags designed for vacuum sealing because they are made to withstand pressure and provide a tight seal. Regular bags may leak or tear.

Does vacuum sealing make food safe indefinitely?
No, vacuum sealing slows spoilage but does not stop the growth of all microorganisms. Vacuum-sealed foods must be stored in the fridge or freezer and food safety guidelines must be followed.

What is the difference between an external vacuum sealer and a chamber vacuum sealer?
An external sealer draws air from the bag externally, while a chamber vacuum sealer places the bag inside a closed chamber. Chamber vacuum sealers are usually better for liquids and intensive use, but they are larger and more expensive.

Can glass containers be vacuum sealed?
Some machines provide a special hose for vacuum sealing compatible containers and jars. Check if the model supports this feature.

How do I care for my vacuum sealer?
Clean the removable parts after each use, especially the sealing bar and gaskets. Follow the user manual to avoid damaging the pump.

In conclusion, choosing a vacuum food sealer depends on your needs, budget, and kitchen space. Start by determining the type of food you will store most often, then look for features that suit you. Remember that prices and offers change, so check local or online stores in Germany and Europe to get the best deal for you.
