Food Tests - AQA Biology B2

In this video we outline the different chemical tests we can carry out on various foods in order to detect what is contained within them. These include sugars, lipids, proteins and starch. We discuss the process of preparing a sample, carrying out the tests, and what we would expect to see to indicate a positive or negative result.
