1. A method of removing yellow color of riboflavin in a lactose solution, the method comprising:
passing a substantially clear lactose solution comprising riboflavin through a conduit having a light source emitting light at a wavelength of 440-475 nm; and
exposing the lactose solution to 500 [J/kg] to 10000 [J/kg] of light from the light source to breakdown the riboflavin comprised within the solution to thereby remove yellow color of riboflavin as it passes through the conduit.
