Course Description and Goals:

It was recognized that an increased number of outbreaks of illness in the world were associated with processed foods illustrating the danger of assuming that foods are free of pathogens simply because they are processed and packaged.

The goal of this course is to provide the necessary knowledge about long-term preservation of packaged food.
