Microbiology Online Pasteurization

Aug 26 2009 · Many relatively heat-resistant (thermoduric) bacteria survive pasteurization but these are unlikely to cause disease or cause refrigerated milk to spoil. Pasteurization Methods In the classic pasteurization treatment of milk the milk was exposed to a temperature of about 63 o C for 30 minutes called the holding method. Most milk Pasteurized milk usually is spoiled by psychrotolerant bacteria typically nonsporeforming Gram-negative rods or Gram-positive sporeforming bacteria. Spoilage of pasteurized milk by Gram-negative rods such as Pseudomonas spp. often involves inadequate heating of milk or more frequently postprocessing contamination.

Spoilage Microorganisms in Milk Food Science

In milk the microorganisms that are principally involved in spoilage are psychrotrophic organisms. Most psychrotrophs are destroyed by pasteurization temperatures however some like Pseudomonas fluorescens Pseudomonas fragi can produce proteolytic and lipolytic extracellular enzymes which are heat stable and capable of causing spoilage. The only real option would be to perform a microbial test prior to pasteurization. If any of the bacteria known to make these enzymes are present then the milk would have to be given a shorter
