Vacuum Sealing Strawberries: 3 Ways to Preserve Freshness

Fresh strawberries are a beloved part of the spring and summertime diet for many. However, these sweet and juicy fruits can easily spoil if not stored properly. Vacuum sealing is an effective way to preserve strawberries so they maintain their freshness over time. In this post, we’ll discuss the benefits of vacuum sealing strawberries, what type of machine to use, tips on prepping them for storage, and long-term storage options that will help keep your berries fresher longer.

Benefits of Vacuum Sealing Strawberries

Vacuum sealing is an excellent method for preserving food because it removes oxygen from the container or bag and locks in moisture to prevent spoilage. The lack of oxygen helps inhibit bacterial growth, which preserves flavor and increases shelf life. This method also keeps out contaminants like dust and dirt, which can cause food to go bad quickly. Additionally, vacuum sealed foods take up less space than unpackaged items, making storage easier.

Strawberry Shelf Life After Vacuum Sealing

Strawberries are particularly sensitive to oxidation and tend to go bad within two days when left unsealed at room temperature. But with proper vacuum sealing, you can extend their shelf life significantly. Properly packaged strawberries can last up to four weeks in the refrigerator, six months in the freezer, and even longer when kept at subzero temperatures.

Types of Vacuum Sealing Machines

There are several types of machines available for vacuum sealing food. Some models are electric while others require manual operation. Electric machines are typically more expensive but allow for greater control over the sealing process. Manual machines are simpler and often less costly, but may require additional effort to create an airtight seal.

Prepping Strawberries for Vacuum Sealing

Before vacuum sealing your strawberries, it’s important to clean and dry them thoroughly. Start by removing any stems or leaves attached to the berries, then wash each one individually under running water. Pat them dry with paper towels before placing them in a single layer on a flat surface such as a baking sheet lined with parchment paper. Once all of the berries have been dried off, you can begin the vacuum sealing process.

DIY vs Store Bought Vacuum Sealing Bags

When it comes to selecting bags for vacuum sealing strawberries, there are two main options: store bought bags and homemade ones. Store bought bags are made from plastic specifically designed for food preservation and usually come with an easy-to-use sealer attachment. Homemade bags can be made from various materials such as aluminum foil or cloth, although they may not provide as tight of a seal as store bought bags. Whichever option you choose, make sure that the material is nonporous so no oxygen can enter into the bag.

Tips for Vacuum Sealing Strawberries Without a Machine

If you don’t own a vacuum sealing machine, you can still achieve great results using common kitchen tools. Start by putting the cleaned and dried strawberries in a heavy-duty zip-top bag. Seal the top almost completely shut, leaving only a small opening near one corner of the bag. Place the open end of the bag inside a drinking glass and slowly submerge it until most of the air has been removed from the bag. Quickly close the opening and remove the bag from the glass. You should now have a nice vacuum-sealed package!

Long Term Storage Options for Vacuum Sealed Strawberries

Once you’ve successfully vacuum sealed your strawberries, it’s important to find an appropriate place to store them. For short-term storage (up to four weeks), refrigeration works well. For longer term storage (more than four weeks), freezing is the best option. Be sure to label each package with the date so you know when they were sealed and how long they’ve been frozen.

How Long Does Vacuum Sealed Fruit Last?

The shelf life of vacuum sealed fruit depends on how it was prepared prior to being sealed and where it is stored after sealing. Generally speaking, refrigerated fruit lasts about four weeks and frozen fruit can stay good for up to six months. To ensure optimal freshness, check regularly for signs of spoilage such as discoloration or mold growth.

Cleaning Up After Vacuum Sealing Strawberries

After vacuum sealing your strawberries, it’s important to clean up any mess that was created during the process. Start by washing all utensils used with warm, soapy water and rinsing with clear water afterwards. Next, wipe down surfaces that came in contact with raw produce with a mild bleach solution to kill any lingering bacteria. Finally, dispose of any empty packaging materials according to local regulations.

Alternatives to Vacuum Sealing Strawberries

If you don’t want to invest in a vacuum sealing machine or don’t have access to one, there are other ways to preserve your strawberries. One popular method is called “jamming,” which involves mixing chopped strawberries with sugar and storing in a jar or container with a tight fitting lid. This method creates an environment that inhibits microbial growth while retaining flavor and texture. Other methods include drying, blanching, and fermenting – all of which offer different levels of protection against spoilage.


Vacuum sealing is an effective way to preserve strawberries and extend their shelf life without sacrificing quality or flavor. While purchasing a vacuum sealing machine might seem intimidating at first, understanding how it works and learning some basic tips can make the process much easier. With the right supplies and knowledge, you’ll be able to enjoy delicious strawberry treats all year round!
