How Long Does Jerky Last Unopened?

Jerky, a popular and convenient snack made from dried meat, is celebrated for its long shelf life and portability. While jerky is known for being a durable food item, its longevity can vary significantly depending on several factors. Knowing how long jerky lasts unopened is essential for ensuring that you enjoy it at its peak quality. This comprehensive guide will explore everything you need to know about the shelf life of jerky, from the types of jerky to best storage practices and more.

Factors Influencing How Long Jerky Lasts Unopened

The shelf life of unopened jerky is influenced by several factors, each playing a critical role in determining how long jerky lasts unopened:

1. Type of Jerky: Does Store-Bought or Homemade Last Longer Unopened?

The type of jerky whether it is store-bought or homemade significantly affects its shelf life.

Commercial Jerky: Store-bought jerky usually contains preservatives like sodium nitrate that extend its shelf life, making it last anywhere from 6 to 12 months. Additionally, commercial jerky is often vacuum-sealed, which prevents moisture and air from entering the packaging, both of which can lead to spoilage. Many brands also include an oxygen absorber packet to further preserve freshness. Store-bought jerky typically has a longer shelf life due to these added preservatives and packaging methods designed to enhance longevity.
Homemade Jerky: Homemade jerky, on the other hand, does not contain the same preservatives found in store-bought varieties. As a result, it typically has a shorter shelf life, generally lasting between 1 to 2 months when stored in optimal conditions. Because it lacks commercial preservatives, homemade jerky is more prone to spoilage, especially if not stored correctly. It is crucial to keep homemade jerky in airtight containers or vacuum-sealed bags to maximize its shelf life.

2. Ingredients That Affect How Long Jerky Lasts Unopened

The ingredients used in making jerky also play a crucial role in determining how long it will last.

Natural Preservatives: Jerky made with natural preservatives like salt, vinegar, and certain spices can have an extended shelf life. These ingredients help inhibit the growth of bacteria and mold, which can cause spoilage. Salt, for example, is a natural preservative that draws moisture out of the meat, reducing the risk of bacterial growth. Similarly, vinegar has antimicrobial properties that help prevent spoilage.
Artificial Preservatives: Many commercial jerky brands use artificial preservatives, such as sodium nitrate or sodium erythorbate, to extend shelf life. These additives prevent the growth of harmful bacteria, like Clostridium botulinum, which can thrive in low-oxygen environments like vacuum-sealed packages. Artificial preservatives can help jerky last for up to a year or more, making them a key factor in the longevity of commercial products. To know more about this preservative and its role, refer to what is sodium nitrate and why is it used in preserved foods?.
Flavorings and Additives: Additional ingredients such as sugar, honey, and various flavorings can affect the shelf life of jerky. While these ingredients can enhance flavor, they can also introduce moisture, which may reduce the overall shelf life. For example, sweetened jerky might attract moisture from the environment, leading to a shorter shelf life if not stored correctly.

3. How Packaging Affects How Long Jerky Lasts Unopened

Packaging and storage methods are critical to ensuring the maximum shelf life of jerky.

Vacuum-Sealed Packaging: This method is one of the most effective ways to prolong the freshness of jerky. By removing air from the package, vacuum-sealing helps prevent oxidation and moisture, which are the primary causes of spoilage. Vacuum-sealed jerky can last up to 12 months or more when stored in a cool, dry place. This packaging is often accompanied by oxygen absorbers, which further enhance the product’s shelf life by eliminating any residual oxygen.
Alternative Packaging Methods: While vacuum-sealing is ideal, other packaging methods can also help extend the shelf life of jerky. Storing jerky in mason jars or dry cans, for example, can be effective for medium-term storage. To dry can jerky, place the pieces in a sterilized jar, seal it tightly, and store it in a cool, dark place. This method can keep jerky fresh for several months.
Environmental Factors: The environment in which jerky is stored also plays a vital role in its longevity. Exposure to light, heat, and humidity can significantly reduce the shelf life of jerky. Storing jerky in a cool, dark, and dry place, such as a pantry or cupboard, is crucial to maintaining its freshness. Avoiding exposure to sunlight and temperature fluctuations is key to preventing spoilage.

4. Optimal Storage Conditions for Unopened Jerky

The conditions in which jerky is stored will directly impact how long it lasts unopened. Proper storage is essential to maintaining the quality and safety of the product.

Temperature: Keeping jerky at a consistent, cool temperature will help extend its shelf life. High temperatures can cause the fats in the jerky to oxidize, leading to rancidity and spoilage. Ideally, jerky should be stored at room temperature or slightly cooler, such as in a pantry or basement.
Humidity: Moisture is one of the biggest threats to the shelf life of jerky. High humidity can cause jerky to absorb moisture from the air, leading to mold growth and spoilage. Storing jerky in airtight containers or vacuum-sealed bags will help protect it from moisture and extend its shelf life.
Light Exposure: Light can cause oxidation and degradation of the product, particularly if the jerky contains fat. Storing jerky in opaque packaging or in a dark place will help prevent light-induced spoilage.
