Farmer Jimmy Doherty investigates the difference between normal cheese and processed cheese. He demonstrates how to make normal cheese, separating the curds and whey from milk by adding acid to separate the solids and liquid. Jimmy fries a piece of each cheese to show how the fat does not seep out of processed cheese. He then goes on to make his normal cheese into processed cheese by adding water and milk proteins.

This clip could be used to generate discussion on food processing, what happens to our food within food factories, how technology allows us to change raw ingredients and how much supermarkets influence the foods we eat. Students could be asked to consider why we process foods. Useful to illustrate functional properties of food - what happens when cheese and processed cheese are heated?
