Can I use the leftover cooking oil again?

pu1. It's not to use it because fat meets oxygen and becomes oxidized, but once it's opened, it's hard not to touch oxygen, so it's better not to use it again

OK

pu2. Use oil several times in chicken restaurants. I think it's okay to use it several times for a while, but it's not good to use it for a few days at home

OK

pu3. Add a little bit of bitter oil to the new oil and use it. Then it can prevent oxidation to some extent. And it's better to store bitter oil in a cool place that doesn't get direct sunlight

OK

pu4. If you use antioxidants (an antioxidant such as tocopherol and polyphenol), it will be difficult at home. Or if you use products high in saturated fatty acids (margarine), it won't oxidize well, but it's not good for your health. So you can rewrite it, but it's better to rewrite it quickly.

OK

pu5. If it can be stored in a vacuum state, it can be used for a long time because it can prevent contact with oxygen. And if you use it as iron or copper to store tempura, it acts as a powerful oxidation promoter, so you shouldn't use such containers

OK
