so i have a container of cooking oil that is sealed but it's best by date was 7 years ago. as long as it's sealed is it fine? thinking about frying with it not using it in a recipe.

It might have gone rancid even if it was sealed. Taste a little bit before you cook with it.

It's all good, bro...go ahead and use it. Don't forget to take pics and post your results.

sadly it's still organic and still prone to all sorts of nasty stuff, it likely wouldn't even work if you used it, toss it out and buy a gallon at walmart for like 5 bux I believe

Pour a small amount out, if it’s sticky to the touch, it’s gone bad, if not, you can still use it.

Any organic chemists lurking? If it was in a dark, cool place, and sealed for 7 years, what could possibly happen to it?

>> No.12239341

>>12239286
I'm not a chemist but it's probably not 100% airtight and was already exposed to oxygen during processing, so it can still have gone rancid. And if it was in a plastic container, it might start to taste like plastic. It probably won't make you sick but it might not taste very good and it'd be a waste to cook food in it.

>> No.12239355

>>12239286
There's still air within the container. Even if you keep it at the back of your cabinet the oil will slowly oxidize over time, but we're talking about years before you get any noticeable difference and even then it's not necessarily rancid.

>>12238922
Taste it, cook something cheap with it, if you don't die you'll be fine. Rancid oil is like chicken, you can't possibly miss it if it has gone bad.

>> No.12239466

>>12238922
cooking oil is like 5-6 bucks dude, is it worth ruining whatever you're cooking to use 7 year old cooking oil on it? Don't even fuck around, just toss it and buy new. A year or two maybe but I'm almost sure it's bad after 7 years.

>> No.12239513

How do you guys dispose of your cooking oil?

I just pour it back into empty oil containers with a funnel then throw it in the trash.

>> No.12239549

>>12239286

Pure oil just goes bad due to chemical processes, no microorganisms, just going rancid. For that oxygen is needed. So it will still be fine probably if it was really airtight sealed. But I doubt the container is still completely hermetic airtight, that means oxygen had enough time to over the years enter and react with it. Still ,do a little sensory check, if still smells good and tastes good then it is in fact still good and you were lucky that indeed no air got into it.

Vegetable oil is a toxic product in general. You should go out of your way to stop using it and all other industrial seed oils.

I've used the same oil in my deep fryer for years, expiration dates aren't relevant when you're heating up oil to 375°

Doesn't that affect the flavor of the food though? Do you at least strain it?

Basically that. Sealed container, throw it in the trash. Safe and what garbage disposal prefers. Pouring it down any drains, kitchen or stormdrain, is a real dumb idea, can clog something awful.

Actual chemfag here, as previously said, oxidative rancidity will the main mode of degradation. Oil may have been packed and sealed with an aluminum cap, but the plastic itself has some non-zero permeability to oxygen and other gases. Just do a small test; cook something with it and if you notice off-flavors, decide whether or not to use for frying. Dispose of it properly/buy a new one etc.

I can just take it to the dump and recycle it.
