Question

(a) Dusty appearance

(b) Yellowish appearance

(c) Whitish appearance

(d) Blackish appearance

I had been asked this question in final exam.

I'm obligated to ask this question of Homogenizer topic in chapter Building Blocks of Dairy Processing of Dairy Engineering

Answer 1

The correct answer is (c) Whitish appearance

To elaborate: Homogenization of milk increases its whitening power due to an increase in the number and surface area of the fat globules. Adsorption of casein micelles and serum proteins on newly created fat globules surface increases scattering of light thereby causing whiter appearance.
