Skim milk is made when all the milk-fat is removed from whole milk, it contains around 0. When curdling occurs, one of the reason can be the use of skim milk because it does not have enough fat content. Skim milk will curdle more than heavy cream, and low-fat creams.

Milk will not begin to curdle until it reaches a temperature of degrees Fahrenheit 82 degrees Celsius. To maximize and speed up the curdling effect, let the temperature climb even higher. If your sauce or soup contains an acidic ingredient, such as wine, tomato or lemon juice to curdle milk rather. In order to counteract the action of the acid, starch may be used as described above.
