FOOD CHEMISTRY (2/2 Credits)

Learning Outcomes:

On successful completion of this Course, students will be able to: Describe about fundamental concepts of macro (water, carbohydrates, lipids, and proteins) and micro components (vitamins, minerals, pigments, flavors, food additives, and toxic components) including interactions, the historical development, compotition, and structure; Measure about the food components both of macro and micro components, and contaminants in food; Identify the chemical reactions principles that involving food components and their application during processing, handling, and storage; Identify about the food contaminants which covers the types of contaminants, the sources of contaminants and the processes by which they contaminate food products.
