popcorn seeds - hechsher

Question

a while back a friend of mine was wondering about whether popcorn seeds need a hechsher- he asked some rabbi and the response was that though theyre obviously kosher - sometimes some companies add animal oil and fry the seeds a bit to extend their shelf life - and therefore one should refrain form using them without a hechsher- What does the Rabbi think of this ? is the oil batel ? it seemingly is less that 60, though i dont know how much oil was used or how long the corn was fried so that maybe the taam actually was absorbed...
