If you’re a fan of peanut butter but also looking to cut down on calories and fat, you may have heard of PB2. PB2 is a powdered peanut butter that has gained popularity in recent years due to its lower calorie and fat content compared to traditional peanut butter.

But with its unique form, you may be wondering: does PB2 go bad? In this article, we’ll dive into the shelf life of PB2 and how to tell if it’s gone bad.

What is PB2?

PB2 has powdered peanut butter made from roasted peanuts that have had most of the oil removed. The resulting product is a fine powder that can be reconstituted with water to make a spreadable peanut butter-like substance. The removal of oil results in a product that has 85% less fat and calories than traditional peanut butter.

How long does PB2 last?

The shelf life of PB2 varies depending on a few factors, such as how it’s stored and the date it was produced. The PB2 company recommends consuming their product within two years of the production date. However, PB2 can last much longer than that if stored properly. It’s best to keep PB2 in a cool, dry place, away from direct sunlight and moisture. If stored properly, PB2 can last up to five years.

Signs that PB2 has gone bad

Just like any other food product, PB2 can go bad if it’s not stored properly or used past its expiration date. Here are a few signs to look out for:

  • Change in color: PB2 should be a light brown color. If it starts to turn darker or develop black spots, it’s a sign that it’s gone bad.
  • Strange odor: PB2 should smell like peanuts. If it has a sour or rancid smell, it’s time to toss it.
  • Off taste: If your reconstituted PB2 tastes off or sour, it’s no longer good to consume.
  • Moisture: If you notice any moisture or clumping in your PB2 powder, it’s a sign that it’s gone bad and has been exposed to moisture.

How to store PB2 properly

When it comes to storing PB2 properly, there are a few things you should keep in mind to ensure that your powdered peanut butter stays fresh and flavorful for as long as possible. Here are some tips on how to store PB2 properly:

  1. Keep it in a cool, dry place: It is best to store PB2 in a cool, dry place away from direct sunlight and moisture. Humidity can cause the powder to clump and lose its texture, while sunlight can cause the oils in the peanut butter to spoil.
  2. Use an airtight container: To prevent moisture and air from getting in, store PB2 in an airtight container such as a plastic container or a glass jar with a tight-fitting lid.
  3. Refrigerate or freeze: PB2 can be stored in the refrigerator or freezer to extend its shelf life. If you don’t plan on using it for a while, consider freezing it in an airtight container to keep it fresh for up to six months.
  4. Don’t mix old and new: If you have some old PB2 that you want to use up, it is best to use it separately from your new PB2. Mixing old and new powder can cause the powder to lose its flavor and texture.

By following these tips, you can ensure that your PB2 stays fresh and delicious for longer. It’s important to store PB2 properly to maintain its quality, texture, and taste.


here are 5 frequently asked questions about PB2:
