Chapter 14, Problem 126A

Interpretation Introduction

Interpretation:

Homogenization processhave to be described.

Concept introduction:

Homogenization is a mechanical process by which the fat molecules in the milk are broken down into smaller sizes.

Answer to Problem 126A

Homogenization is a mechanical process by which the fat molecules in the milk are broken down into smaller sizes and the smaller size fat molecules are dispersed evenly throughout the milk instead of rising to the top to make colloidal solution like emulsion. This process resists the tendency of the fat molecules to make cream layer and float on the top of the milk.

Explanation of Solution

Without homogenization the fat molecules will float on the top of the milk. Homogenization processcan easily breaks the fat molecules in the milk into smaller sizes in such a way that the smaller size fat molecules are dispersed into the milk to make colloidal solution like emulsion. So, this process resists the tendency of the fat molecules to make cream layer and float on the top of the milk.
