Description

Food preservatives are commonly used in many foods we purchase and consume daily. While some food preservation techniques have been practiced for millennia, such as salting, drying and smoking, others have been made possible on a commercial scale by 20th century advancements in technology, such as freezing and pasteurizing.

This film takes a look at why foods are preserved and the many advantages we gain as consumers, from the ability to store food for long periods of time to the causes of food spoilage; the differences between natural and artificial food preservatives; preservation techniques using temperature; and water and oxygen removal.
