Why is translucent spot produced when food containing lipid is rubbed against a paper? Is it related to adsorption?

It means that the light rays are scattered by the fat molecules and can be absorbed and re-emitted internally thereby transmitting some light to the other side. But I do not know how the mechanism actually works.
