Causes of Food Spoilage - an excerpt from Food Preservation Techniques
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.
"Food Preservation Techniques", now available from VEA, takes a look at why foods are preserved and the many advantages we as consumers gain from the ability to store food for long periods of time. It explores causes of food spoilage; the differences between natural and artificial food preservatives; preservation techniques using temperature; and water and oxygen removal. Featuring an interview and demonstrations of preservation techniques, this film is an ideal resource for anyone undertaking food and food technology related courses, as well as hospitality.
