EXTENSIONS

• 

Research and write about food preservation methods in different 

periods of time. 

• 

Hypothesize about other ways you can think of that science  

might help us preserve foods in the future. How would you  

design an experiment to test your hypothesis? Indicate which 

foods you’d use your “process” for. 

• 

Relate your pathogen to this experiment and record the  

information in your food safety portfolio. 

MODULE 3: 

PROCESSING AND TRANSPORTATION

ULTRA HIGH PRESSURE TREATMENT 

3. 

Why can you use ultra high pressure treatment 

with orange juice and not a marshmallow?  

(Orange juice contains water that protects it  

from being crushed by the ultra high pressure.  

A marshmallow contains air and would be  

compressed to the size of a BB.)
