In this Science Update, students explore why the cheese tastes different when pizza is re-heated. Science NetLinks provides a link to the audio file, a written transcript, and questions that engage students in a discussion of how the chemical components of cheese are altered when they are heated a second time. Students also consider how water-soluble and fat-soluble flavor compounds affect the taste of cheese. The lesson also provides links to websites for the Wisconsin Center for Dairy Research, The University of Guelph’s Department of Food Science, The Discovery Channel’s “Kitchen Chemistry,” and “Making Sense of Taste” from Scientific American.
