Peanut butter contains a mixture of all three macronutrient molecules: carbohydrates, protein, and fat. Carbohydrates include sugars and starch, as well as fiber, which is indigestible.
There are also vitamins and minerals in peanut butter, but you don’t digest those, despite the fact that they’re an important part of peanut butter’s nutrition. Instead, you absorb the vitamins and minerals whole. Fiber, on the other hand, passes undigested through your gut.
The Digestion Of Peanut Butter
In your large intestine, you complete the processes of starch and protein digestion, you digest certain sugars and you also begin digesting fats.
Peanut butter contains a fair amount of fat; it varies depending upon the type of peanut butter and the way it’s made, but it’s always a significant percentage of the composition.
To digest fat, your small intestine uses both enzymes and emulsifying agents called bile salts. The bile salts help the fats mix with water-based digestive juices.
A minimal amount of peanut butter (one or two teaspoons) can keep you satiated for thirty minutes up to a few hours. It all depends on how peanut butter works with YOUR body.
Does Peanut Butter Spoil?
Unopened Peanut Butter
Peanut butter is gooey and delicious, yet it can remain at room temperature for months without spoiling – approximately 12 months.
Low moisture levels and high oil content keep this butter from going bad for quite some time but don’t go ignoring that expiration date just yet.
Peanut butter can go rancid in about a year and lose its flavor. While fungi and bacteria won’t ruin your peanut butter, oxygenation eventually will.
In fact, the high fat content leaves PB vulnerable to a different type of food spoilage called rancidification.
This isn’t the same as oil separation, when the fats disassociate from peanut particles and pool on top of the jar’s contents. This happens normally in peanut butter and can be resolved simply by stirring.
Instead, rancidification is a chemical process in which oxygen breaks down the molecular structures of lipids (the technical term for fats) and changes the flavor and odor of food in rather unappetizing ways.
As peanut butter is exposed to more and more oxygen over its lifetime, it becomes likelier to undergo this decay.
Opened Peanut Butter
An open jar of peanut butter will spoil much quickly if it isn’t placed in the refrigerator. It will stay fresh for up to 3 months.
Storing it in the fridge after opening will prolong its quality for another 3–4 months. If left unrefrigerated, oil separation can occur.
