Laurie Wheeler, RNC, MN, IBCLC >> Since the foul taste is caused by the action of an enzyme (lipase), the milk has to be sterilized *before* storage to prevent the the process of lipolysis (breakdown of the lipids). As long as enzyme in the milk is allowed to reamain active, the milk will develop the nasty taste. Milk which is already spoiled cannot be "fixed". Think of it as being partially digested already...... Diane DiCarlo LLLL Brooklyn, NY
