Linking Biochemistry Concepts to Food Safety Using Yogurt as a Model
This laboratory activity was designed to strengthen our Food and Nutritional Science students’ knowledge of biochemistry concepts and the relationship between these concepts and food science. The result was a laboratory experience in which biochemistry concepts are taught using yogurt as a model, in order to link those concepts to food safety, an important area of food science. The students employed a colorimetric method to measure the lactase activity of bacterial strains found in commercial yogurts and were encouraged to relate the activity to bacterial lactic acid production, fermentation, and food safety. Students were assessed with pre- and post-test exams, laboratory reports, class performance rubrics, and the Intrinsic Motivation Inventory (IMI). The result demonstrated that the students successfully completed the learning objectives and were motivated during the activity. This exercise could be used as a template for a simplified and engaging way to introduce food science majors, as well as other students, to complex biochemistry and molecular biology concepts using food, particularly yogurt, as a model.
期刊介绍:
The Institute of Food Technologists (IFT) publishes the Journal of Food Science Education (JFSE) to serve the interest of its members in the field of food science education at all levels. The journal is aimed at all those committed to the improvement of food science education, including primary, secondary, undergraduate and graduate, continuing, and workplace education. It serves as an international forum for scholarly and innovative development in all aspects of food science education for "teachers" (individuals who facilitate, mentor, or instruct) and "students" (individuals who are the focus of learning efforts).
