is milk a solution?

Answer 1

It's something called a colloid. A solution is when the different ingredients are mixed together perfectly, with a chemical reaction. A suspension is like sand and water, they don't mix at all. Mixtures, on the other hand, are like sugar and water. They mix, but no chemical reaction occurs.

Answer 2

Milk constituents:
The quantities of the main milk constituents can vary considerably depending on the individual animal, its breed, stage of lactation, age and health status. Herd management practices and environmental conditions also influence milk composition. The average composition of cows milk is shown in Table 1.

Main constituent:

Water
85.5 – 89.5
87.0
Total solids
10.5 – 14.5
13.0
Fat
2.5 – 6.0
4.0
Proteins
2.9 – 5.0
3.4
Lactose
3.6 – 5.5
4.8
Minerals
0.6 – 0.9
0.8
Water is the main constituent of milk and much milk processing is designed to remove water from milk or reduce the moisture content of the product.
