Nails for Breakfast?

Most people know that breakfast cereals are fortified with iron and other essential minerals and vitamins. What they don’t know is that in some cases the iron is actually added in the form of metallic, elemental iron—nails for breakfast! In this demonstration, iron is extracted from cereal using a magnetic stirring bar and the amount of iron is compared with the nutritional label information. Reaction with hydrochloric acid and qualitative tests for dissolved iron simulate what happens when the iron dissolves in the acidic contents of the stomach.

Are food additives healthy or unhealthy? This is a controversial topic in society today. Many people associate food additives with highly processed convenience foods that are unhealthy. But not all food additives are unhealthy. Iodine, in the form of potassium iodide, was the first additive approved by the federal government for use in foods. Potassium iodide is added to salt to prevent thyroid diseases caused by a lack of iodine in the diet. The presence of iodide in iodized salt can be demonstrated by reaction with chlorine water, a strong oxidizing agent.

Enzymatic Hydrolysis of Sucrose

Using simple laboratory techniques, demonstrate the production of the enzyme invertase (sucrase) by yeast. The demonstration can lead to a discussion of the role invertase plays in yeast metabolism.
