Testing Food For Nutrients
Configure & Price
IS.3013
This experiment will help students understand the importance of proteins, carbohydrates, and lipids in living organisms. They will learn to identify a positive test result for proteins using biuret reagent and examine the reaction between Benedict’s reagent and a simple sugar. Using iodine/potassium iodide they will test for the presence of starch and test for the presence of lipids using a fat-soluble dye.
Includes:
- 25mL iodine/potassium iodide solution
- 25mL biuret reagent
- 25mL Benedict’s solution
- 25mL 1.0% sudan III stain
- 25mL vegetable oil
- 10g soluble starch
- 10g albumin
- 10g glucose
