Food Detective

Play Online Food Detective
You jump into the Food Detective activity by gathering simple tools and a curious mind. You measure sugar with a glucose meter by mixing a bit of food in water, dipping a test strip, and reading the number on the screen. It works fast and anyone with basic gear can try it, but it misses some sugar types. If you need exact numbers you turn to a lab method that breaks down every kind of sugar.
Starch and fat come next. You drop iodine on a tiny piece of potato or corn and watch the sample turn blue-black if starch lives there. For fat you press food on a white paper towel, hold it against a pale plate, and look for greasy rings. You can also shake a sample in ethanol, set it aside, and see fat rise to the top where you scoop and weigh it.
Protein testing wraps up the session. You stir a food sample with a strong base, add copper sulfate, and wait for blue to shift to purple. The deeper the hue, the more protein hides in your snack. These hands-on checks keep things clear and help you learn what lurks inside every bite.
