What exactly is food? In this program we introduce students to the science behind the food we eat. We start by describing what food is, the components found in food and why we need carbohydrates, protein, vitamins and minerals, fats and oils. And we show how to test different foods to determine which of these components are present. We also examine keeping food safe and how it should be handled and stored. Packaging, use-by-dates and refrigeration are also covered as well as long-term storage methods. Food allergies, the concept of genetically modified foods and possible problems with gene technology are also discussed in The Science of Foods.
