About Homogenization: Developing better-tasting milk Virtual Lab Simulation
Dairy products are very common in your daily life, but do you know how are they made? In the Homogenization simulation, help Adam the farmer to improve his milk business and learn about the different processes needed to manufacture dairy products – from raw milk to the supermarket.
Introduction to mixtures
Did you know that milk is a mixture of water, fat globules and protein micelles? Before you start the process of homogenization, you will be introduced to the different kinds of mixtures that you can find in foods, such as colloids and emulsions. In this simulation, you will take a microscopic look at a drop of milk and discover its structure. By doing so, you will observe what makes processed commercial milk different from raw milk.
The milk homogenization process
Once you understand the basics of mixtures, colloids, and emulsions, you are ready to perform homogenization. In this simulation, you will use a portable homogenizer based on a 2-step homogenization. You will take samples to analyze under the microscope, and compare the differences between particle sizes of raw milk and milk that is homogenized at different steps of the process. To better understand the mechanics of the homogenizer, immerse yourself in 3D animations showcasing the main pistons and valves that make the machine work.
At the end of the simulation, you will meet Adam again and tell him all about your newly-acquired knowledge of milk homogenization. Will you be able to help him understand the concept of homogenization to improve his business and provide tasty milk to more people?
