When milk spoils as caused mainly by coliform bacteria, it changes in consistency, appearance, and smell. It also undergoes a chemical change as the bacteria produce acid that causes the milk to clot once spoiled.
As far as I know there is no exact formula for the milk as its composition varies so it brought to my wonderings if there is any specific formula for spoiled milk. Of course there is formula if you will go through chemical analysis of the substance. Spoiled milk formula I suggest would be different from the unspoiled as chemical changes had undergone.♥

The two main groups of bacteria in milk are Lactic acids and Coliforms. Lactic acid is the natural bacteria present in milk and dairy products. Coliforms are the main reason for milk spoilage. Pasteurization kills almost all of the bacteria, but some of the bacteria that cause milk to spoil still remain. If these bacteria are given an environment that promotes growth, they will rapidly multiply.
When milk spoils it changes in consistency, appearance, and smell. Spoiled milk also undergoes a chemical change. As the milk spoils, the bacteria produce acid. It is the acid that causes the milk to clot. You can compare the acidity of the test milks by using indicator strips.

Milk that is not refrigerated after milking and packaging will spoil, the lactose in the milk will turn to lactic acid and you will have yogurt, buttermilk, and Yuck!
