Does your peanut butter have a pool of oil on top? Don't pour it out! It's actually a good sign of how natural your peanut butter is.
Many peanut butters have an oily substance floating on top. It's the natural peanut oils rising to the top.
Grinding peanuts releases their oils. It's these oils that make peanut butter so creamy. Peanut oil is also a liquid at room temperature. So as the peanut butter sits, the oil rises and collects at the top. But what if your peanut butter has no oily pool?
That's often a sign it has added oils like cottonseed, rapeseed, soybean, or palm oil. They mix with the peanut oil preventing any oil at the top.
Or it has added with hydrogenated oil or stabilizer. So what actually is hydrogenated oil? Why is it so bad?
Hydrogenation is a process in which a liquid unsaturated fat is turned into a solid fat by adding hydrogen. During this processing, a type of fat called trans fat is made, which raises LDL (“bad”) cholesterol, lowers HDL (“good”) cholesterol and has other harmful effects, such as causing heart diseases and cancers. Food companies use hydrogenated oil to help make peanut butter smoother, creamier, and also increases the shelf life at room temperature.
If you prefer all-natural peanut butter, mixing that extra oil back in can be a mess. But pouring it off will leave you with a dried-out peanut butter.
When separation happens, all you need to do is to give it a good stir and mix before consuming then you'll be good to go. If you did not know about it and your butter has began to turn dry towards the end, just add a little bit of any oil of your choice and it'll be smooth again.
