Does PB2 go bad?

In this brief article, we are going to answer the question “Does PB2 go bad?” We will also discuss other related questions regarding PB2. In the end, we will list the major differences and similarities between traditional peanut butter and PB2.

Yes, PB2 can go bad just like any regular peanut butter. If properly hermetically packed, powdered peanut butter has a reported stable shelf life of 4-5 years from packing. After PB2 has been combined into peanut butter, it may be stored for a long time without affecting the taste or texture. 

How long does PB2 last?

Powdered peanut butter is a novel option that is prepared by squeezing the bulk of oil from peanuts and then grinding them into a powder. The majority of labels say that they will survive 10–12 months if left unopened and 4–6 months if opened. 

What is PB2?

PB2 is powdered peanut butter and is a unique take on traditional peanut butter.   

It’s prepared by squeezing oils out of peanuts before grinding them into a fine powder.

Powdered peanut butter obtained this way is flavorful but has 85 percent fewer fat calories. It can be rehydrated to produce a peanut paste.

Some people praise PB2 as a low-calorie alternative to peanut butter, while others worry about the nutritional implications of eliminating the fat from peanuts.

Is PB2 bad for you?

PB2 is not too bad for your health. There is a tiny amount of added salt and sugar in it, so it’s best to not eat it too much. Because PB2 is readily diluted or blended into liquids, it might be an excellent substitute for nut butter for those having difficulty eating nut butter because of its consistency.

Small quantities of sugar and salt are added to assist improve the product’s flavor.

However, PB2 doesn’t contain a lot of sugar, just over 1 gram per serving. So, sugar overconsumption is not an issue with it unless you eat too much of it in one sitting.  

PB2 contains only 94 mg of salt per serving, although it’s less than most forms of regular salted peanut butter, which contains 147 mg in one serving.  

Does PB2 spoil?

If properly hermetically packed, it has a stated shelf life of 4-5 years from the date of packing. If stored at temperatures below 70 degrees Fahrenheit, it has a lifespan of 5 to 6 years. 

Does PB2 need refrigeration after opening?

Yes, in the cupboard, an open jar can last up to three months. After that, the peanut butter should be kept in the refrigerator. Oil separation can happen if you don’t refrigerate.

Keep it in a cold, dry area with the lid tightly closed.

Do you add water to PB2?

It’s easy to make powdered peanut butter from PB2. We recommend combining 2 teaspoons of PB2 powder with 1 tablespoon of water.

What are the similarities and differences between PB2 and regular peanut butter?

PB2 contains less fat than regular peanut butter

Traditional peanut butter includes 16 grams of fat per two tablespoons, however, PB2 contains just 1.5 grams of fat in the same amount.

Peanuts, on the other hand, contain mostly unsaturated fats, which are typically considered healthy.

According to studies, the major type of fat contained in peanuts, oleic acid, lowers blood pressure, reduces heart diseases, and reduce inflammation

Choosing PB2 over full-fat peanut butter might be a wasted chance to increase your monounsaturated fat intake.

However, cause for worry is if you consume additional monounsaturated fats in your diet.

PB2 may contain fewer fat-soluble vitamins

Fat-soluble vitamins are lost due to the loss of fat in powdered peanut butter.

Peanut butter isn’t particularly high in fat-soluble vitamins, but it is high in vitamin E. Two teaspoons give 14% of the recommended daily intake.

Vitamin E is a fat-soluble antioxidant that protects the body from free radicals. Antioxidants aid in the reduction of inflammation.

Defatted peanut flour has no fat and no vitamin E and is manufactured by crushing defatted peanuts.

Since most of the lipids in PB2 have been removed, powdered peanut butter is unlikely to be an effective source of vitamin E.

The majority of people do not consume enough vitamin E on a regular basis.  

As a result, conventional peanut butter may be a preferable alternative for people who do not already consume foods high in vitamin E.
