High Heating Rates Affect Greatly the Inactivation Rate of Escherichia coli.

abstract：:Bacterial spores are extremely resistant life-forms that play an important role in food spoilage and foodborne disease. The return of spores to a vegetative cell state is a three-step process, these being activation, germination, and emergence. High-pressure (HP) processing is known to induce germination in part of th...
