Verification of radio frequency pasteurization process for in-shelln almonds

摘要

Salmonella outbreaks related to consumption of raw almonds have forced nut industry to seek effective pasteurization processes. Radio frequency (RF) treatment is a potential pasteurization method for controlling Salmonella while maintaining product quality. Escherichia coli ATCC 25922 is nonpathogenic and can be used as a surrogate of pathogenic Salmonella when their thermo-tolerances are equivalent. Since thermal resistance of target pathogens can be reduced by raising water activity in dry sam
