Have you ever wondered how to make your food last longer and reduce waste? One of the key factors in food spoilage is exposure to oxygen.
In the quest to find effective ways to extend the life of our food, one solution stands out: vacuum sealing. This powerful method has long been used by restaurants and food manufacturers for its ability to preserve freshness and taste. Now, these kitchen appliances it’s becoming increasingly popular in homes across the world.
Understanding vacuum sealing
This is a method of packaging that removes air from the plastic bags prior to sealing. The absence of oxygen creates an environment where bacteria, fungi, and other spoilage microorganisms can't grow, thereby preserving the food.
This technique involves placing items in a plastic bag, removing air from the inside, and sealing the package. The intent is to extend the shelf life of foods and, with flexible package forms, to reduce the volume they occupy.
Benefits of vacuum sealing
Extended Shelf Life
One of the most significant benefits of vacuum sealing is the ability to extend the shelf life of food products. By eliminating most of the oxygen, a vacuum sealer prevents the chemical reactions triggered by oxygen that cause food to spoil. It's estimated that a vacuum sealer can extend the shelf life of food by 3-5 times compared to conventional storage methods.
Prevention of Freezer Burn
Freezer burn occurs when cold air dries out the surfaces of frozen food, leading to discoloration and a change in flavor and texture. By forming a tight seal around the food and removing excess air, a vacuum sealer helps to prevent this problem, keeping your frozen foods tasting fresher for longer.
Saves Money and Reduces Waste
With a vacuum sealer machine, you can buy food in bulk, divide it into meal-sized portions, and seal and store it. This not only saves money but also reduces food waste. Additionally, you can store leftovers for future consumption instead of throwing them away.
Enhanced Marination
Vacuum sealers can also enhance the marination of meats and vegetables. By creating a tight seal around the food, the process allows the marinade to penetrate deeper and quicker, reducing the marination time significantly.
Things to consider when using a vacuum sealer
While a vacuum sealer offers numerous benefits, there are certain things you need to be aware of. Not all foods are suitable for vacuum sealing and food storage. Foods with high moisture content or those that produce gases during storage (like some vegetables) may not be ideal for this method. Always do your research before vacuum-sealing any new types of food.
Also, remember that while a vacuum sealer extends the shelf life of foods, it doesn't eliminate the need for refrigeration or freezing for certain items. Always store your vacuum-sealed foods in the appropriate conditions to ensure their safety and quality.
Conclusion
A vacuum sealer is a versatile and valuable tool in any kitchen. From extending the shelf life of foods to preventing freezer burn, saving money, and enhancing marination, the benefits are many. If you're looking to take your food storage for preservation to the next level, consider investing in a vacuum sealer.
Remember though, like any tool, it's essential to understand how to use it correctly. With a little bit of research and practice, you'll be vacuum-sealing like a pro in no time!

Optimal performance of vacuum sealers: a deep dive
A vacuum sealer, a device that extracts air from a package and then seals it to preserve freshness, is a significant game-changer in the food industry and even in home kitchens. But what makes a vacuum sealer perform at its best? Let's delve into the details.
Power and efficiency
For optimal performance, a vacuum sealer should have a high wattage and a robust vacuum pump. A product like the NESCO® VS-12 Deluxe Vacuum Sealer, for example, boasts a 130-watt double vacuum pump, ensuring maximum air extraction for larger food items. The power of the motor determines how quickly and efficiently the machine can remove air from the bag, thereby affecting the overall sealing result.
Variable settings
Another crucial factor for optimal performance is having variable settings. For example, the NESCO® VS-12 Deluxe Vacuum Sealer includes three settings—dry, moist, and double—that allow you to customize the sealing process based on the type of food you're preserving. These settings ensure that you get the best possible vacuum seal, whether you're storing dry goods like nuts or moist foods such as fresh meat or cooked leftovers.
Consistent and reliable sealing
The sealing mechanism is another essential component that affects the vacuum sealer's performance. A vacuum sealer must provide a consistent and reliable vacuum seal to ensure the food remains airtight and fresh. Dual heat sealing strips, like those found on the NESCO® VS-12 Deluxe Vacuum Sealer, guarantee an optimal vacuum level and airtight seal every time.
Versatility
The best vacuum sealers are versatile, allowing you to work with various bag sizes and types. They should also be compatible with accessories like handheld sealers for preserving food in the refrigerator and pantry.
Durability
Lastly, durability is key for optimal performance. High-quality materials and construction, backed by a solid warranty, indicate a vacuum sealer built to last. A reliable vacuum sealer will consistently perform well over time, providing you with fresh, well-preserved food whenever you need it.
The optimal performance of a vacuum sealer depends on several factors, including power, efficiency, variable settings, consistent sealing, versatility, and durability. When all these elements come together, you have a machine that can effectively preserve your food, saving you money and reducing waste. So, whether you're a professional chef or a home cook looking to prolong the shelf life of your groceries, a vacuum sealer could be an invaluable addition to your kitchen.
Powerful Suction: A vacuum sealer like the Nesco VS-12 typically offers powerful suction capabilities, which can help ensure maximum air extraction for better food preservation.
Ease of Use: Many vacuum sealers are designed with user-friendly interfaces and straightforward operations, which can make the sealing process simple and quick.
Versatility: Versatile in its applications, being able to seal a wide range of food items from meats to vegetables and more.
Size: Some vacuum sealers can be quite large and bulky, taking up considerable counter space. However, the Nesco vacuum sealer is large enough to do the job but small enough to store without taking up too much space.
Cost of Bags: The ongoing cost of purchasing specially designed vacuum seal bags for the vacuum sealer can add up over time.
Learning Curve: While many vacuum sealers are designed to be user-friendly, there can still be a learning curve involved, particularly for those who have never used one before.
Reliability: The vacuum sealer works but is not good enough to pull all the air out on dry or wet products. We think this is an issue with a small percentage of machines.
Our Thoughts - Like most other products, there will always be a small percentage of vacuum sealers that fail or have small issues.

When stored in the freezer, food preserved with the FoodSaver System can last up to three years while maintaining its fresh and flavorful taste. This means you can take advantage of bulk buying or sales without worrying about the food going bad before you can consume it.
Savings
By extending the shelf life of your food, this vacuum sealer helps you save money. You can buy food in larger quantities when it's on sale and preserve it for later use. This ability to store food for longer periods also reduces the amount of food that gets wasted, leading to significant savings over time.
Freshness and flavor retention
This vacuum sealer removes air from the packaging, which helps to prevent freezer burn. This results in food that retains its original flavor, texture, and freshness. Even after months in the freezer, your food will still taste as good as the day you bought it.
Versatility
This vacuum sealer isn't just for long-term freezer storage. It's equally effective for refrigerating food. Prep-ahead meals, leftovers, and produce stored in the fridge will stay fresh for weeks instead of spoiling in days. This makes meal planning and prep much more efficient and manageable.
Easy to use
The FoodSaver System is user-friendly and straightforward to operate. The process is simple: place your food in the bag, insert the open end into the machine, and let the FoodSaver do the rest. It removes the air and seals the bag, creating an airtight package that locks in freshness and flavor.
Space efficiency
The vacuum seal bags used by the FoodSaver System are flexible, allowing them to conform to the shape of the food and take up less space than rigid containers. This helps optimize storage space in your fridge or freezer.
The FoodSaver System offers a practical and efficient solution to food preservation. By extending the shelf life of food, maintaining freshness and flavor, and reducing waste, it provides a host of benefits that make it a worthy addition to any kitchen.

Handheld Vacuum Sealer: The inclusion of a handheld vacuum sealer adds versatility, allowing for the sealing of zipper bags, canisters, containers, and more.
Airtight Food Storage: By removing air from specially designed bags, this machine ensures airtight storage, which can significantly extend the shelf life of food items.
Sous Vide Application: The ability to create airtight seals also makes this vacuum sealer machine ideal for sous vide cooking, a method that involves cooking food slowly in a temperature-controlled water bath.
Cost: While the machine itself may be reasonably priced, the ongoing cost of purchasing proprietary vacuum seal bags and pre-cut bags could add up over time.
Longevity: A few customers mentioned that they expected the machine to last longer than three months.
Learning Curve: Some users might find it takes time to get used to the automatic bag detection feature.
Our Thoughts - In contrast to prior automatic sealing models that were impractical and wasteful, this vacuum sealer is a game-changer. Its adjustable settings allow for sealing closer to the bag's edge, optimizing bag usage and enabling easy reuse without compromising storage space.
FAQs
Are vacuum sealers worth the money?
Vacuum sealers can indeed be worth the money, particularly for those who buy in bulk, prepare meals in advance, or wish to reduce food waste. Here's why:
Longer Shelf Life: Vacuum sealers work by removing most of the air from the packaging, thereby slowing down the oxidation process that leads to food spoilage. This can significantly extend the shelf life of your food, keeping it fresh for longer.
Bulk Buying and Meal Prep: If you often buy food in bulk or prepare meals in advance, a vacuum sealer can be a great investment. You can separate your food into meal-sized portions, seal each one individually, and then freeze them. This not only makes meal planning easier but also helps you take advantage of bulk discounts without worrying about the food going bad.
Reduced Food Waste: By extending the shelf life of your food, vacuum sealers can help cut down on food waste. This not only saves you money but is also better for the environment.
Better Taste: Vacuum sealing can also improve the taste of your food. It works by locking in the flavors, so your food will often taste better when it's been vacuum-sealed.
Sous Vide Cooking: If you're a fan of sous vide cooking, a vacuum sealer is almost essential. It ensures that the bag is perfectly sealed and safe to cook with, and many chefs believe it gives better results.
Cost of the vacuum sealer
However, there are some considerations. The upfront cost of a vacuum sealer can be high, especially for high-end models. Plus, you'll need to keep buying the bags or rolls, which is an ongoing cost.
Conclusion
Whether a vacuum sealer is worth the money largely depends on your personal cooking and eating habits. If you frequently find yourself throwing away spoiled food, or if you like to buy in bulk and cook sous vide, a vacuum sealer could be a worthy investment.
Is there anything you shouldn't vacuum seal?
Here are some items that you should avoid vacuum-sealing, as sourced from various online resources:
Soft Cheeses: Soft cheeses like brie and camembert can harbor bacteria that grow in low-oxygen environments, which can lead to foodborne illness.
Raw Onions and Garlic: These foods release gases when stored, which could potentially interfere with the vacuum seal.
Cruciferous Vegetables: Vegetables such as broccoli, cabbage, Brussels sprouts, and cauliflower also emit gases and should not be vacuum-sealed.
Raw Mushrooms: Raw mushrooms have a high moisture content and may decay faster if vacuum-sealed.
Fresh Bananas: Similar to raw mushrooms, bananas have high moisture content which can lead to quicker spoilage if vacuum-sealed.
Freshly Cooked or Steamed Vegetables: These can create a breeding ground for bacteria due to their residual heat and moisture.
Bread: Vacuum sealing can crush bread due to its soft and spongy nature.
Please note that vacuum sealing does not replace the need for refrigeration or freezing. Perishable foods still need to be stored properly after being vacuum-sealed.
Is vacuum sealing better than freezer bags?
Vacuum sealing has several advantages over using freezer bags, according to various sources.
Longer Shelf Life: Vacuum-sealed foods can last 3 to 5 times longer than food stored in baggies or plastic containers due to the lack of oxygen which slows the growth of bacteria and mold.
Better Preservation of Quality: Vacuum sealing can help maintain the color, texture, taste, and nutritional value of food better than freezer bags. This is because vacuum sealing removes most of the oxygen, slowing down the oxidation process that can degrade these attributes.
Space Efficiency: Vacuum-sealed items take up less space in the freezer compared to items in a freezer bag.
Prevents Freezer Burn: Vacuum sealing significantly reduces the likelihood of freezer burn, as it eliminates the air that causes it.
However, vacuum sealing also has some drawbacks compared to freezer bags. These include the upfront cost of the machine, the ongoing cost of the bags, and the time required to seal each bag.
In conclusion, while both methods have their pros and cons, vacuum sealing appears to be superior to freezer bags in terms of food preservation.
Why are potatoes not normally vacuum sealed?
Potatoes are not normally vacuum sealed for a few reasons:
Raw potatoes retain moisture: Raw potatoes have a high moisture content. When vacuum-sealed, this moisture is retained within the package which can lead to faster spoilage or potential growth of bacteria and mold.
Texture changes: Vacuum sealing and freezing raw potatoes can result in texture changes once they are defrosted. This can affect the quality of the potato when it's cooked.
Possibility of Botulism: Raw potatoes in particular can harbor the bacterium Clostridium botulinum, which thrives in low-oxygen environments like those created by vacuum sealing.
However, if you still want to vacuum seal your potatoes, it's recommended to blanch, cook, or dehydrate them first to kill any bacteria and reduce their moisture content.
