Objectives

In food industry as well as in the food laboratories a large amount of multivariate physical and chemical process analysesare performed daily. Furthermore, quality analyses on all kinds of raw materials, processes and products are performed.

Explorative data analysis / chemometrics offers completely new possibilities for the exploitation of such data sets thanks to the development of modern computer technology. The objective of the course is to introduce the student to the basic chemometric techniques and to demonstrate their application on industrial data sets for quality control in food technology, on data from modern on-line measuring techniques, and on data from factory laboratories / research laboratories. The student will- after the course is completed- be able to independently apply the most common chemometric methods.

Content

The course will give a "step-by-step" theoretical introduction to chemometrics supported by practical examples as well as a short introduction to modern measurement techniques, including spectroscopic methods and image analysis apparatus. The theoretical chemometric part will include a thorough description of methods for classification (e.g. principal component analysis) and calibration (e.g. partial least squares regression), process control and image analysis.

Teaching procedure:

Lectures and computer exercises. The exercises are based on datasets collected in the industry and / or the students own data sets. The exercises form the basis for the preparation of a report.

Literature:

Kim Esbensen: Multivariate Analysis in Practice (1994) as well as notes and other papers.

Duration:

Lectures: 42 hours

Exercises: 42 hours

Project and preparation: 86 hours

Examination: 10 hours

Total: 180 hours
