When it comes to preserving food, vacuum sealing is one of the most effective methods. But if you’re a fan of jerky, you may wonder just how long that vacuum-sealed goodness will last. In this comprehensive guide, we’ll explore the shelf life of vacuum-sealed jerky, factors that influence its longevity, and best practices for storage. Whether you’ve made homemade jerky or purchased some from your favorite store, understanding how to keep it fresh is essential for maximally enjoying this nutritious snack.
The Basics of Jerky and Vacuum Sealing
Jerky is a popular snack made by drying meat to inhibit microbial growth and spoilage. Typically, beef is the most common meat used, but jerky can also be made from turkey, pork, chicken, and even fish. The drying process removes moisture, which is crucial for extending the jerky’s shelf life. Vacuum sealing, on the other hand, involves removing air from a package before sealing it, creating an airtight environment that further inhibits the growth of bacteria and oxidation that cause food spoilage.
The Shelf Life of Vacuum-Sealed Jerky
The shelf life of vacuum-sealed jerky can vary based on a multitude of factors including the type of meat used, how the jerky was made, and the storage conditions. But generally speaking, vacuum-sealed jerky can last for several months to even years under optimal conditions.
Commercially Made vs. Homemade Jerky
First, let’s differentiate between commercially made and homemade jerky:
Commercially made jerky: Store-bought jerky is typically treated with preservatives, packaged under strict quality controls, and often vacuum-sealed right at the factory. It generally lasts longer and can remain edible for up to 1 to 2 years when vacuum sealed and stored correctly.
Homemade jerky: While homemade jerky offers the advantage of using your favorite flavors and knowing exactly what’s in it, it usually has a shorter shelf life. Vacuum-sealed homemade jerky can last about 1 to 3 months when stored in a cool, dark place.
Factors Influencing Shelf Life
To maximize the lifespan of your vacuum-sealed jerky, it’s important to consider several factors that can affect its longevity.
1. Quality of the Meat
The starting quality of the meat you use greatly affects how long your jerky will last. Fresh, high-quality meat is less likely to harbor bacteria, which can contribute to spoilage. Always choose cuts of meat that are fresh, lean, and free from any blemishes.
2. Preparation Method
The method you use to prepare jerky can also influence its shelf life. The FDA recommends heating meat to an internal temperature of 160°F (71°C) for beef and 165°F (74°C) for chicken and turkey before the drying process. This step helps to kill potential bacteria and increases the shelf life significantly.
3. Vacuum Sealing Process
Not every vacuum sealing process is created equal. To ensure the best seal, make sure to use a quality vacuum sealer that effectively removes all the air. Any air pockets can promote oxidation and spoilage.
4. Storage Conditions
Where you store your vacuum-sealed jerky matters. Heat, humidity, and exposure to light can all degrade the quality of jerky. Storing it in a cool, dark place, ideally at room temperature or in a refrigerator, can help prolong its freshness.
Signs That Jerky Has Spoiled
Even vacuum-sealed jerky will eventually spoil, so it’s crucial to be aware of the signs:
- Odor: If jerky has developed a sour or off smell, it’s likely spoiled.
- Texture: If the jerky becomes excessively moist or mushy, discard it.
- Appearance: Any discoloration or unusual spots can indicate spoilage.
You can enjoy jerky longer by being vigilant about such changes.

So, the next time you grab that vacuum-sealed bag of jerky, you’ll be armed with the knowledge you need to make the most of your favorite snack. Enjoy those flavors, and don’t forget to savor every bite!
What is the shelf life of vacuum-sealed jerky?
The shelf life of vacuum-sealed jerky primarily depends on the type of meat used, the moisture content at the time of sealing, and the storage conditions. Generally, commercially produced vacuum-sealed jerky can last between 1 to 2 years when stored in a cool, dry environment. The vacuum sealing process removes air, significantly reducing the chance of oxidation and microbial growth, which helps in extending the shelf life.
For homemade vacuum-sealed jerky, the shelf life can be shorter, typically ranging from 6 months to 1 year. This variance arises from factors such as the drying process and whether preservatives were used. It’s crucial to monitor jerky for any signs of spoilage, such as off-odors or discoloration, especially if it has been stored for an extended period.
Does vacuum sealing affect the flavor of jerky?
Vacuum sealing can help preserve the flavor of jerky by locking in the essential oils and spices that contribute to its taste.
