This situation is generally not due to the growth of insects.

The open edges in the middle of the flax seeds may be caused by cracked or damaged shells. This condition usually has no impact on consumption, because the outer shell of the flaxseed is only a thin film, while the kernel itself is intact.

Normally, flaxseeds are small, flat seeds with no openings or edges. If the surface is uneven and there are signs of gnawing, it may be because the linseeds are contaminated or have been infested by insects.
