Everyone loves a milkshake but not the fat and calories. With this two day lesson/lab, your students will learn how food scientists use natural thickeners(polysaccharides) to increase the viscosity of a liquid and make a fat free smoothie taste like a milkshake. Students will create several different samples diet smoothie using varying concentrations of xanthan gum. They will measure the viscosity of each sample, plot the data and perform taste tests to determine the preferential amount of xanthan gum.
