That's how the get the stuff out. Now, why is it bad? I watched another video on canola oil--made by the same people, so not from tree-hugging-hippy-freak-os that hate everything except foliage--and they freaking add bleach to it to make it lighter in color.
K, I'm not totally cool with eating bleach.
But I'll still totally use vegetable oil. 'Cuz I can.
