Does lactose in milk change when heated?
On heating at a temperature above 100 °C, lactose is degraded to acids with a concomitant increase in titratable acidity (Figs. 9.5 and 9.6). Formic acid is the principal acid formed; lactic acid represents only ~5 % of the acids formed.
Why does lactose-free milk curdle when heated?
The Science of Curdled Milk Milk is a mixture (called an emulsion) of butterfat, proteins, and water. When milk is boiled, the three components of the emulsion break apart: the milk proteins coagulate and separate from the water, producing what is commonly known as curdled milk.

The product is treated by flash sterilization at 290 °F (twice the temperature of normal pasteurization). This high temperature kills all bacteria or microorganisms. The milk is then packed into sterilized containers and is shelf-stable for six months.
How does temperature affect lactase activity?
Cooler temperatures slow the rate of lactase's function, while at extremely high temperatures -- those above 135 degrees Fahrenheit, for example -- lactase can become denatured, or lose its shape. A protein's shape is responsible for its function, so when it becomes denatured, lactase loses its ability to function.
Why does warm milk make me sick?
