Got a big can of sesame oil but it does not have any expiration date?

Question

It says cooking oil. It also says it was packed September 2007. So it has been a year. But there's no expiration date. I got it at an asian store. When I asked the person at the cashiers he said it's all good and i can still use it for a long time. But I wonder if he said that just so that he sells it? Do you think it's good to use, or should I return it?

My 2nd part of the question.. are you aware of sesame oil also being useful for body massage purposes? And is that a different kind of sesame oil, or the cooking oil itself?

Thanks guys.

Answer 1

You'll know when it's gone bad because the smell will make your head snap back. The massage oil usually has a fragrance in it, but you could use it for that purpose.

Answer 2

You can smell the oil to see if it's good.  Rancid oil has a distinctive odor.  If it is still good, you should store it in the fridge to help it keep longer.

I'm not sure about using it for body massage.  When I buy it, it's usually about three dollars for four ounces, so it's too expensive to use for anything except as a flavoring.
