Why did my olive oil change colour?

So, I bought a bottle of olive oil the other day for cooking, and it was very green in colour, which I found odd, but I didn’t think anything was wrong with it so I bought it anyways. Now, less than a week later, it’s gone it’s normal yellow colour. I have been using it. What caused this?

There’s a Q&A on this site http://funadvice.com/r/14t1nhms10e where the question of colour change is answered, doesn’t talk about such short periods though, but I would guess it’s the same logic.

Answer #2

i never knew olive oil was yellow :O

its usually green in color and shouldnt change at all :S ive had a bottle of extra virgin olive oil for over 4 weeks and it stayed green….

Answer #3

O_o Well…. I don’t know honestly. All olive oil I’ve gotten has been yellow.

Answer #4

Oxidation can cause that…fresh pressed olive oil is naturally green, but the more it’s exposed to the air, the more it lightens to the yellow you’re more familiar with.
