Course Number and Title: FSY 220 Food Chemistry
This course applies the basic scientific principles of food systems and chemical reactions for major food ingredients: carbohydrates, lipids, proteins, and other components found in fresh and processed food products with respect to food quality. Reactions that affect color, flavor, texture, nutrition, and safety of food are emphasized.
- Describe the major functional groups that occur in food molecules. (CCC 1, 2, 5, 6; PGC 1)
- Explain the significance of food enzymatic reactions. (CCC 1, 2, 5; PGC 1)
- Discuss the chemical and functional properties of the major food components. (CCC 1, 2, 5; PGC 1, 5)
- Determine major changes in color, flavor, and texture of foods during handling, processing, and storage. (CCC 1, 2, 5; PGC 1, 2, 5)
- Identify the importance of food acidity in terms of pH and titratable acidity. (CCC 1, 2, 5, 6; PGC 1, 2, 5)
- Use laboratory techniques to apply scientific principles to comprehend chemical properties in foods. (CCC 1, 2, 3, 4, 5, 6; PGC 1, 2, 4, 5, 6, 7)
See Core Curriculum Competencies and Program Graduate Competencies at the end of the syllabus. CCPOs are linked to every competency they develop.

Students must demonstrate proficiency on all CCPOs at a minimal 75 percent level to successfully complete the course. The grade will be determined using the Delaware Tech grading system:
Students should refer to the Student Handbook for information on the Academic Standing Policy, the Academic Integrity Policy, Student Rights and Responsibilities, and other policies relevant to their academic progress.
Calculated using the following weighted average
Percentage of final grade
Summative: Exams (6) (equally weighted)
Formative: Lab activity/written assignments (equally weighted)
