Our days of crying over spoiled milk could be over, thanks to Cornell food scientists.Milk undergoes heat treatment -- pasteurization -- to kill off microbes that can cause food spoilage and disease, but certain bacterial strains can survive this heat shock as spores and cause milk to curdle in storage. Researchers in the Milk Quality Improvement Program at Cornell's College of Agriculture and Lif
