Is there a test to tell the difference betweeen canola and vegetable oil?

Could you tell by just looking at it? Is there a more definitive test that could be done to tell the difference? Like if I have two bottles of unlabeled oil, how would I know which one is canola?





Thanks so much !Is there a test to tell the difference betweeen canola and vegetable oil?
Canola is a tad lighter color than vegetable oil and has a distinctive after taste.





Edit: Wesson is what I use also and if you take a small taste of each you will know which one is the canola.. it has an odd after taste to it.





Edit 2: If you have the 48oz bottle of vegetable oil I can tell you that the number on the bottom is 705-5 =)Is there a test to tell the difference betweeen canola and vegetable oil?
By appearance, Canola oil is a little paler; not as golden as some vegetable oils. But - this will also depend on the grade of the oil and the blend.





As to a test? Chemist might be able to give you a definitive answer. Taste is a little different, but again, this will depend on the blend in the vegetable oil.
