How Long Does Peanut Butter Last?

How Long Does Peanut Butter Last?

 

Today, we’re going to crack open the lid on this question and get to the bottom of peanut butter’s shelf life. So, grab a spoon (or a celery stick if you’re feeling fancy), and let’s dig in!

A Nutty Look at Shelf Life

First off, it’s important to understand that not all peanut butters are created equal when it comes to shelf life. Generally, we have two main types on our shelves: natural peanut butter, which often has oil separation and a simpler ingredient list, and commercial peanut butter, which has added stabilizers to prevent oil separation and extend shelf life.

According to the FDA and food safety experts, an unopened jar of commercial peanut butter can typically last 6-24 months in the pantry. Once opened, you’re looking at about 2-3 months of prime peanut butter enjoyment—if it lasts that long in your household!

Natural peanut butter, on the other hand, has a shorter shelf life due to the lack of stabilizers. Unopened, you can expect it to last 2-3 months in the pantry, and after opening, it should be consumed within a month. For the best quality and to extend its life a bit, you can store the opened jar in the fridge, where it can last up to 6 months.

Signs of Spoilage

As much as we’d like it to be eternal, peanut butter can go bad. Here’s what to look out for:

  • Smell: Fresh peanut butter has a nutty, sweet aroma. If your peanut butter smells sour or just… off, it’s time to say goodbye.
  • Taste: If it smells okay but you’re still unsure, a tiny taste won’t hurt. Rancid peanut butter will have an unpleasant, bitter flavor.
  • Texture: If the peanut butter is dry, hard, or has a chalky texture, it’s lost its mojo.
  • Mold: This is rare, but if you see any signs of mold growth, toss it right out. No second guesses here.

Storage Smarts

To keep your peanut butter at its best, follow these simple storage tips:

  • Keep it cool: Store your peanut butter in a cool, dry place away from direct sunlight and heat sources.
  • Go airtight: Once opened, ensure the lid is closed tightly after each use to prevent exposure to air, which can accelerate spoilage.
  • Use clean utensils: Always use a clean knife or spoon to scoop out your peanut butter to prevent contamination with food particles or bacteria.

Fun Peanut Butter Facts

  • Versatility: Peanut butter isn’t just for PB&J sandwiches. It’s a great source of protein and can be used in a variety of recipes, from smoothies to sauces.
  • Nutrition: It’s packed with healthy fats, vitamins B and E, and antioxidants.
  • Popularity: According to the National Peanut Board, the average American consumes around 7 pounds of peanut butter each year!

The FDA and Peanut Butter

The FDA regulates peanut butter, ensuring that it contains at least 90% peanuts with no artificial sweeteners, colors, or preservatives. This means that even your store-bought jars are kept as natural as possible, which is great news for our health and our taste buds.

Key Takeaways

  • Shelf Life: Unopened commercial peanut butter can last 6-24 months, while natural peanut butter lasts 2-3 months. Once opened, consume commercial peanut butter within 2-3 months and natural peanut butter within 1 month for best quality.
  • Storage: Keep it in a cool, dry place and use clean utensils to prevent spoilage.
  • Spoilage: Watch out for changes in smell, taste, texture, and look out for mold.
  • Nutrition: Peanut butter is a healthy and versatile food that is regulated by the FDA for quality and safety.
