Spring 2004
Instructor:
Philip Koehler
Credit:
3 Semester hrs; lecture and lab.
Description:
Instruments that are applied to analysis of food will be discussed and demonstrated.

Upon successful completion of this course students should have the ability to:
- search the scientific literature and find appropriate instrumental analytical procedures for analysis of food products
- develop analytical procedures for determination of common food components and ingredients
- understand how instruments used in food analysis work
- operate instruments (vis, UV, IR, NMR, MS, fluoresence, AA, GLC, HPLC) used in food and nutrient analysis
- interpret the data generated by these instruments
- apply appropriate statistical measures to those data
Grading will be based on the best four out of five 100 point Exams plus a 200 point Final. No make-up exams will be given since everyone can discard out one exam score. Graduate students will be required to submit a term paper dealing with some phase of instrumental analysis.
Attendance: Attendance is highly recommended to achieve the course goals. These goals require both an accumulation of facts and practical experience that is best acquired by class attendance. Lab attendance is mandatory.
All students are referred to the University of Georgia Academic Honesty Policy as set forth in the UGA Student Handbook
