(b) Transparent bags

(c) Opaque containers

I got this question in a national level competition.

This intriguing question comes from Homogenizer topic in section Building Blocks of Dairy Processing of Dairy Engineering

Answer 1

Right answer is (c) Opaque containers

The best explanation: Homogenized milk is more susceptible to oxidized flavors caused by natural or artificial light than unhomogenized milk. To prevent the development of off-flavors, homogenized milk must be packaged in opaque containers, such as cartons, plastic containers or colored bottles.
