Using simple and safe chemical tests, students can very quickly and easily identify the major nutrients in common foods. Students use step-by-step instructions to test common foods for the presence of carbohydrates, proteins, lipids. They also perform qualitative (detect a presence) and quantitative (how much) tests of Vitamin C by using a very simple drop-by-drop titration process. Over 100 tests for unknowns can be performed on each food group. This kit does not use corrosive agents or toxic substances.
NOTE: Because of limited shelf-life of certain components, the Food Analysis Kit should be used within three weeks of receipt.
