Food Science Science Fair Project

Uncovering Food's Nutritional Content

Uncovering Food's Nutritional Content | Science Fair Projects | STEM Projects
Ever wondered what's in the food you eat? With this project, you can find out! You'll use chemical tests to learn what foods contain carbohydrates, lipids, and/or proteins.


The hypothesis is that different types of foods contain different amounts of carbohydrates, lipids, and proteins.

Method & Materials

You will use test tubes, Benedict's solution, Lugol's solution, Biuret reagent, and other materials to test different types of food for carbohydrates, lipids, and proteins.
You will need 8 test tubes, a test-tube rack, a lab apron, Benedict's solution, a stirring rod, masking tape, plastic gloves, Biuret reagent, a test-tube holder, a pencil, safety goggles, Lugol's solution, distilled water, newsprint paper, and food substances such as apple juice, melted butter, raw egg white, raw fish, raw potato, raw spinach, and vegetable oil.


Through this experiment, you can learn about the different types of organic compounds found in food. You can observe the amount of starch, sugar, lipids, and proteins in each food substance and compare the results.

Why do this project?

This science project is interesting and unique because it allows you to explore the nutritional content of different types of food.

Also Consider

Experiment variations to consider include testing different types of food or testing for additional organic compounds.
