The fat has a lower density than water, so if the milk is left to stand it floats to the top, and can be skimmed off. This gives skimmed milk.
n milk, proteins form structures called micelles. The micelles are on average about 150 nanometres in diameter, and this very small size means they are able to scatter light that hits them. The overall effect of this scattering by the huge number of micelles in milk is that it looks white.
Lactose is a sugar found only in milk and dairy products. In our bodies, the enzyme lactase breaks it down into two smaller sugars, galactose and glucose. However, some people don’t produce enough lactase for this enzymatic breakdown to happen – these people are lactose intolerant. In their digestive systems, lactose passes through unchanged, and eventually reaches the colon. There, bacteria break it down, producing gas which can cause discomfort.
