All the Handy Tips About Groundnut Oil And Its Stocking

Peanut Oil

Groundnut oil can’t be called a common product compared to other oils, however, this natural foodstuff has found its place in many kitchens due to its nutty flavor and usefulness.

Since it is quite rare, people often wonder how to store peanut oil correctly.

Let’s see what we can discover about this!

How Long Does Peanut Oil Last?

Like any other natural vegetable or nut oil, groundnut product is rather durable. Of course, when buying a flask of it in a store, we can find the best-by date indicated on the tag but it only shows until when the oil will keep its optimal potency.

For sure, this date doesn’t show that the product will become spoiled right after the expiry date.

Nevertheless, it doesn’t prove that peanut oil can last forever either.

Like any organic product, it has its final term of use. However, if we follow the basic storage requirements, it will be possible to prolong its lifespan to its most. In this case, it will be possible to stock groundnut oil for months and sometimes even for one or two years after its expiry date!

But before we discover what actions to take to reach that goal, let’s see how long we can safely stock this product at home if we do everything right.

Unopened oil Stock it for 1-2 years past the expiry date safely
Opened oil Lasts for 6-12 months at most
Used oil Keep it for nearly 2 weeks (equal to 3-5 uses)

Remember though that this information may slightly vary since the duration of storage hangs significantly upon the quality of the product and better oils last longer than their cheaper counterparts.

Storage Tips And Nuances

So how do we store peanut oil?

In fact, it’s not a big deal.

  1. Keep the bottle tightly screwed all the time to prevent contamination
  2. Stock it in a shaded and dry place
  3. Keep the bottle away from heating objects
  4.  Refrigeration is not a must even for an unscrewed bottle but if the plan is to stock it for a year or so, you’d better chill the foodstuff
  5. In case some utilized product must be saved, never let it stay in the deep fryer. Drain it to the plastic/glass tank after it is not hot anymore and double-check there are no food particles in it.

Since unscrewed oil stays fine for twelve months for sure, it would be more reasonable to go for this one for deep frying.

On the other hand, if you already unscrewed the bottle, it’s ok to exploit it if the product is still fine and usable.

In case you notice any symptoms of rancidity, don’t deep fry on this oil since it can be harmful!
