Can I keep the used cooking oil and use it again?

A. 1

I'm telling you not to use it because fat meets oxygen and becomes oxidized and decomposes.
Once opened, it is difficult to avoid contact with oxygen, so it is recommended not to use it again.

We use oil several times in chicken restaurants.
I think it'll be okay if you use it several times for a short time
It's not good to spend a few days at home.

You can use it by adding a little bit of bitter oil to the new oil.
This prevents oxidation to some extent.
And it is recommended to store bitter oil in a cool place that is out of direct sunlight.

You can use antioxidants (an antioxidant such as tocopherol and polyphenol), but it's hard at home.
Or if you use a product that has a lot of saturated fatty acids (margarine), it doesn't oxidize very well, but it's not good for your health.
So you can rewrite it, but it looks good to rewrite it quickly.

If it can be stored in a vacuum state, it can be used for a long time because it prevents contact with oxygen.
And if you use it as iron or copper when storing tempura, it acts as a powerful oxidation promoter, so you shouldn't use such containers.
