Ultimate Guide to Long-Term Storage of Peanut Butter

Peanut butter is a staple in many households and can last for a long time if stored properly. However, due to its high fat content, peanut butter can go rancid over time if not stored correctly. In this blog post, we’ll be discussing some tips on how to store peanut butter long term.

Types of Peanut Butter

Before we dive into the storage techniques, let’s talk about the different types of peanut butter available in the market. Peanut butters come in two main varieties – natural and processed.

Natural peanut butter is made from only ground peanuts without any added oils or sugars. This type of peanut butter has a shorter shelf life as it does not have any preservatives.

Processed peanut butter contains additional ingredients such as hydrogenated oil and sugar which give it a longer shelf life compared to natural varieties.

Tip #1: Choose Natural Peanut Butter

If you’re looking for long-term storage options, it’s best to choose natural varieties that don’t contain additives or preservatives. Although these might have a shorter shelf-life compared to processed ones (3-6 months after opening), they are still safe for consumption as long as they are refrigerated within this duration.

Tip #2: Keep It Cool & Dry

Peanut Butter should be kept away from heat sources and moisture when storing them When exposed to heat and humidity over an extended period then they will start turning rancid quickly even before their expiration date approaches.. The ideal temperature range for storing peanut butter is between 60°F – 70°F (15°C -21°C).

Remember! Do not freeze your Peanut Butter unless required by specific brands since freezing temperatures dry out oils causing unpleasant texture changes while thawing down

Tip #4: Store Opened Jars Upside Down in Refrigerator

When storing opened jars of peanut butter, it’s best to keep them upside down. This helps the oils distribute evenly throughout the jar and prevents them from separating at the top surface of a jar causing oiliness after opening.

It may also help to place a piece of plastic wrap over the open end before screwing on the lid for added protection.

Tip #5: Vacuum Sealing

If you want to extend your natural peanut butter shelf life beyond 6 months then vacuum sealing is an excellent option that will protect your Peanut Butter from moisture and air exposure, which are crucial factors that cause rancidity.

Vacuum sealers remove all oxygen content in food packaging keeping out moisture and humidity while maintaining their quality until when they need consumption.
