Beef jerky is a snack that people have cherished for centuries due to its long shelf life, convenience, and savory taste. Whether you’re an outdoor enthusiast, a busy professional, or someone who enjoys a quick and satisfying snack, beef jerky fits the bill. However, it’s important to understand how long beef jerky lasts and what factors influence its longevity. This comprehensive guide explores every aspect of beef jerky’s shelf life, from the role of ingredients and preservatives to the best storage practices.
What is Beef Jerky and Why Does It Last So Long?
Beef jerky is essentially dried, cured meat seasoned and dehydrated to preserve it. The word “jerky” originates from the Quechua word “charki,” which means “dried, salted meat.” The process of making jerky removes moisture from the meat, which enhances its flavor and significantly increases its shelf life. Today, beef jerky comes in various flavors and forms, catering to different tastes and dietary preferences. It has become a favorite snack for people on the go, providing a quick source of protein and energy.
Types of Beef Jerky and Their Shelf Life
There are two main types of beef jerky available:
- Store-Bought Beef Jerky Shelf Life: Mass production of this jerky type often includes preservatives like sodium nitrite, which extends its shelf life. Manufacturers typically package store-bought jerky in vacuum-sealed or nitrogen-flushed bags to protect it from oxygen and moisture. These products are designed to last for a considerable period, making them ideal for long-term storage or emergency food supplies.
- Homemade Beef Jerky Shelf Life: Homemade jerky is created using personal recipes, often with fewer or no preservatives, impacting its shelf life. The drying process typically uses a home dehydrator or oven, with seasoning that can vary widely, offering a more customized flavor. However, because it lacks commercial preservatives, homemade jerky typically doesn’t last as long as store-bought versions.
For those who enjoy experimenting with recipes at home, exploring creative ways to use beef products in meals can be interesting. For example, you can repurpose leftover taco shells in different dishes. Learn more about what to do with leftover taco shells here.
Factors Influencing How Long Beef Jerky Lasts
Several factors influence the longevity of jerky. Understanding these factors helps you make informed decisions on how to store your jerky to ensure it stays fresh for as long as possible.
Ingredients and Preservatives Affecting Beef Jerky Shelf Life
The ingredients, particularly preservatives, play a significant role in determining the shelf life of jerky. Store-bought jerky usually includes chemical preservatives like sodium nitrite and potassium sorbate, which inhibit bacteria and mold growth, thereby extending the product’s shelf life. These preservatives are highly effective at maintaining the freshness and safety of the jerky over time.
In contrast, homemade jerky might not include these preservatives, relying instead on natural preservatives like salt and vinegar. While these natural preservatives help to some extent, they generally don’t provide the same level of protection as their chemical counterparts. As a result, homemade jerky has a shorter shelf life unless you store it under optimal conditions.
How Moisture Content and Dehydration Level Impact Beef Jerky Longevity
The moisture content of beef jerky is another critical factor in its longevity. The dehydration process used to make jerky removes a significant amount of water from the meat. This reduction in moisture concentrates the flavors and creates an environment that’s less hospitable to bacteria, which require moisture to thrive.
Properly dehydrated jerky should have a moisture content of about 15-20%. At this level, the jerky is dry enough to inhibit bacterial growth but still retains enough moisture to be chewy and enjoyable. However, if the jerky is not adequately dehydrated, it may retain too much moisture, leading to spoilage. Conversely, jerky that’s overly dry may become tough and less palatable.
Best Packaging Methods to Extend Beef Jerky Shelf Life
Packaging plays a crucial role in preserving the freshness of jerky. The best packaging methods for extending the shelf life of jerky include:
- Vacuum Sealing: This method involves removing air from the packaging before sealing it, reducing the amount of oxygen available to spoilage-causing bacteria. Vacuum-sealed beef jerky lasts significantly longer than jerky stored in a regular plastic bag. The absence of oxygen slows down the oxidation process, which can otherwise lead to rancidity.
- Nitrogen-Flushed Packaging: Some commercial brands use nitrogen to displace oxygen in the packaging. This technique helps prevent oxidation and extends the shelf life of the product. Nitrogen is an inert gas that doesn’t react with the components of the jerky, thus preserving its flavor and texture over time.
- Airtight Containers: For homemade jerky, storing it in an airtight container prevents moisture and air from entering, which are primary factors in spoilage. Glass jars, resealable plastic bags, or specially designed jerky storage containers all work well to keep homemade jerky fresh.
Ideal Storage Conditions to Keep Beef Jerky Fresh
The conditions under which you store beef jerky are paramount to its longevity. Temperature and humidity are the two most critical factors:
- Cool, Dry Places: Store beef jerky in a cool, dry place to maximize its shelf life. High temperatures cause the fats in the jerky to oxidize, leading to rancidity, while humidity can rehydrate the jerky, creating an environment conducive to bacterial growth. A pantry or cupboard away from direct sunlight is ideal.
- Refrigeration: Refrigerating beef jerky can extend its shelf life, especially after you open the package. Refrigeration slows down the oxidation process and helps maintain the jerky’s flavor and texture. However, take care to avoid condensation, which can introduce moisture to the jerky.

Shelf Life of Store-Bought Beef Jerky
Store-bought beef jerky is designed with longevity in mind. Thanks to the preservatives and packaging methods manufacturers use, unopened packages last for a considerable period, making them ideal for long-term storage or emergency preparedness.
How Long Does Unopened Store-Bought Beef Jerky Last?
When you store unopened store-bought beef jerky properly, it lasts anywhere from 1 to 2 years. The exact duration depends on several factors, including the brand, the packaging, and the presence of preservatives. For instance, Jack Link’s beef jerky lasts up to one year when unopened, thanks to its vacuum-sealed packaging and preservatives.
How Long Does Opened Store-Bought Beef Jerky Last?
Once you open a package of beef jerky, its shelf life decreases significantly. The exposure to air and moisture starts to degrade the quality of the jerky. Most manufacturers recommend consuming opened jerky within a week. However, storing the jerky in an airtight container or refrigeration extends its usability.
It’s important to note that while the best-by date provides a good indication of freshness, jerky remains safe to eat after this date as long as it has been stored properly. However, the quality in terms of flavor and texture might not be as good.
Shelf Life of Homemade Beef Jerky
Homemade beef jerky offers a unique, personalized flavor experience, but it generally doesn’t last as long as store-bought counterparts. This is largely due to the absence of commercial preservatives and the variability in dehydration and storage methods.
Storage Methods
Proper storage is key to maximizing the shelf life of homemade beef jerky. After you dehydrate the jerky, cool it down, and then store it in an airtight container. Ideally, keep it in a cool, dry place, similar to store-bought jerky. However, because homemade jerky often lacks preservatives, it typically lasts only 1 to 2 months under these conditions.
Oxygen Absorbers and Vacuum Sealing
You can use oxygen absorbers and vacuum-sealed bags to extend the shelf life of homemade jerky. Oxygen absorbers remove residual oxygen from the storage container, further preventing oxidation and spoilage. Vacuum sealing the jerky significantly prolongs its shelf life, potentially extending it to up to a year, especially if you store it in a refrigerator or freezer.

How to Properly Store Beef Jerky
Proper storage is essential to prolonging the shelf life of beef jerky. Whether it’s store-bought or homemade, following these storage tips will help keep your jerky fresh and enjoyable for as long as possible.
Keep it Airtight
After opening a package of beef jerky, minimize its exposure to air. Store it in an airtight container or resealable plastic bag to prevent moisture from entering, which is one of the main causes of spoilage. For homemade jerky, airtight storage is even more critical due to the lack of preservatives.
Refrigerate After Opening
While beef jerky is typically shelf-stable, refrigerating it after opening extends its shelf life. This is especially true for homemade jerky, which might be more susceptible to spoilage. Refrigeration slows down the oxidation process and helps maintain the jerky’s flavor and texture.
Use Oxygen Absorbers
Oxygen absorbers are small packets that remove oxygen from the storage container, helping to prevent spoilage. These are particularly useful for long-term storage or if you’re storing jerky in a less-than-ideal environment. Adding oxygen absorbers to your storage method helps extend the life of your jerky, whether it’s store-bought or homemade.
Freeze for Long-Term Storage
If you don’t plan on consuming your beef jerky within a few months, freezing is an excellent option for long-term storage. Frozen jerky lasts up to a year or more without significant loss of quality. Just be sure to store it in a vacuum-sealed bag or airtight container to prevent freezer burn.
Can Beef Jerky Go Bad?
Yes, beef jerky can eventually go bad if you don’t store it properly. Recognizing the signs of spoilage is important to ensure you’re not consuming jerky that’s past its prime.
Unpleasant Smell
One of the first signs that beef jerky has gone bad is an off smell. Fresh jerky has a rich, savory aroma, but spoiled jerky may have a sour, rancid, or otherwise unpleasant odor. If the smell is off, discard the jerky.
Changes in Texture
Another sign of spoilage is a change in texture. Jerky should be firm but pliable. If your jerky has become overly hard, dry, or sticky, it may be past its prime. This could be due to exposure to air or moisture, which leads to the breakdown of the jerky’s structure.
Mold Growth
While it’s rare, mold can develop on beef jerky that has been exposed to moisture. Mold appears as white, green, or black spots on the surface of the jerky. If you notice any mold, discard the jerky immediately, as mold can render it unsafe to eat.
Making Beef Jerky Last Longer: Tips & Tricks
