Why is milk opaque and not transparent?

Answer 1

casein (the protein in milk) and the fat molecules deflect and scatter the light particles so they cannot bounce back to your eye from the other side of the glass, instead bouncing off the molecules in the milk and that leads to only being able to see the white milk.

if trypsin (digests protein) is introduced then the casein will break down and the light will not be deflected off it, instead it will travel through the now clearer milk to the other side of the glass and bounce back to your eye.
