I have been writing a paper on milk and milk properties and have 
had difficulties identifying the pH of spoiled milk.  I know that 
fresh milk has a pH of anywhere from 6.0-7.3 and that curdled 
milk has a pH of 5.3, yet I cannot find at which pH level milk is 
considered spoiled (when it starts to smell bad but before it 
actually curdles).  Any help you can give me would be 
appreciated.
