752-1022-00LSelected Topics in Food ChemistryW3 credits2GL. Nyström, T. M. Amrein, M. Erzinger
AbstractThe course is divided into two parts:
The first part focusses mainly on the process contaminant acrylamide and its relation to Maillard reaction. Further topics such as food taints are also covered.
The second part is centered in cereal chemistry: main chemical components related to physicochemical, technological and nutritional properties of grain products.
ObjectiveThe main goal of the course are:
a) Understand formation and mitigation of acrylamide
b) Know challenges of food taints and important examples
c) Understand the chemical composition and properties of cereal grains as raw materials for food, changes in composition during grain processing, and the effects of both on the nutritional properties of grain based products, such as breads, pasta, and breakfast cereals.
ContentThe first part of the course focusses on acrylamide. Regulatory aspects, chemistry of formation, options for mitigation for different foods are presented in detail. Food taints are another topic and some examples and challenges in food are highlighted.
The second part of the course covers fundamental and modern aspects of cereal chemistry: composition of grains, physicochemical properties of main grain components (starch, proteins, fibres, lipids), and their effects on technological and nutritional properties of cereal grain products. Focus is put on chemical reactions and changes during common food processing (dough making, baking, extrusion, fermentation), reflecting also their effects on the nutritional and sensory properties of grain products. Furthermore, a special emphasis is put on dietary fibres and related phytochemicals in grains: Different dietary fibre compounds found in cereals and cereal products (cellulose, arabinoxylan, beta-glucan, resistant starch etc.), co-passengers of dietary fibre (phenolic acids, plant sterols, tocols, folates, alkylresorcinols, avenanthramides), factors affecting their levels in foods, and methods used for the analysis of their content and composition.

752-1202-00LFood Safety and Quality ManagementW3 credits2GT. Gude
AbstractThe course procures the general rules of a quality management system and its application in the food chain to guarantee food safety. Therefore the HACCP concept will be touched in relation to risk management and risk assessment. Furthermore the origin of limits as well as the analytical proof will be highlighted. Finally general principles of laboratory testing will be discussed.
ObjectiveComprehensive knowledge to take over the responsibility for and organisation of quality assurance in a food processing environment.
ContentThe following lists in note form the relevant topics:
Definition of (Food) Quality
TQM/quality management
Q.A in the food chain (manufacturer/retail)
Food Quality, -Safety (also give by examples)
Food Limits - origin of and how to get them
HACCP introduction, risk management, -assessment
Self control concepts
GFSI/Standards BRC, IFS, ISO
Statistical Process Control

AbstractA journal-club style seminar, in which preselected recent scientific articles are analyzed, presented and discussed by students. The relevant topics are selected from the wider area of food microbiology, including fundamental and applied disciplines. Students learn how state-of -the-art research is designed, conducted, appropriately analyzed, and presented.
ObjectiveStudents will learn how state-of -the-art research is designed, conducted, appropriately analyzed, and presented.
ContentSeveral pre-selected, recently published papers will be up for selection by the students. All papers were selected from recent literature and reflect the wider area of food microbiology, including fundamental research (molecular biology, genetics, biochemistry) and applied disciplines (diagnostics, control, epidemiology). Groups of 2 students each will pick a paper for in-depth analysis (mostly work done at home and/or library) and presentation to the other students.
Lecture notesNo script needed. Pre-selected papers will be assigned to student groups in the kick-off meeting (first lecture); PDF copies will be available to all students.
LiteratureNo specific books needed. Access to a library and web-based literature search is required.
Prerequisites / NoticeTeamwork in small groups of 2 students
752-5102-00LFood Fermentation BiotechnologyW3 credits2VC. Lacroix, C. Schwab, M. Stevens
AbstractFor this integration course, selected and current topics in bioprocess technology as applied to food will be selected to complement the teaching program in Food Biotechnology. Special emphasis will be given on downstream processing, bioprocess development, and metabolic engineering with current applications of microorganisms for producing high quality and safe food.
ObjectiveThe presentation and discussion of selected topics of food fermentation biotechnology:
- to present the main strategies for downstream processing for fermented media
- to provide examples of recent process development and future trends for production of high quality food and food ingredients.
- to develop experience for formulation and design of research and development projects relating to food fermentation technologies

This course will integrate knowledge in bioprocess technology, as well as microbiology and microbial physiology.
ContentThis course will address selected and current topics on bioprocess applied to food. As well, this course will allow the integration of concepts in food biotechnology through literature search and presentation of topics by students. Specialists from the Laboratory of Food Biotechnology will contribute to the selected topics as follows:

• New technologies for food fermentation
• Downstream processing treatments
• Metabolic engineering

Students will be required to complete a personal project on a selected aspect of bioprocesses and process evaluation. The project will involve information research and analysis followed by an oral presentation.
Lecture notesCopy of the power point slides from lectures will be provided.
LiteratureA list of references will be given at the beginning of the course for the different topics presented during this course.
Prerequisites / NoticeThis course is taught in English.
752-1300-01LFood Toxicology Information W2 credits1VS. J. Sturla, N. Antczak
AbstractBuilds on a foundation in Toxicology fundamentals to address situations and toxins relevant to Food Science, Nutrition, and Food Safety & Quality.
ObjectiveCourse objectives are for the student to have a broad awareness of toxicant classes and toxicants relevant to food, and to know their identities (i.e. chemical structure or biological nature), origins, relevance of human exposures, general mode of biological action, and potential mitigation strategies.
ContentBuilds on a foundation in Toxicology fundamentals to address situations relevant to Food Science, Nutrition, and Food Safety & Quality. Representative topics: Toxic Phytochemicals and Mycotoxins, Industrial Contaminants and Packaging Materials, Toxicants formed During Food Processing, Alcohol and Tobacco. The class is comprised of bi-weekly lectures, independent reading, and preparation of an independent evaluation of a food-related toxin.
LiteratureReading from the primary literature will be referenced in class and posted to the course website.
Prerequisites / NoticeThe course "Introduction to Toxicology" (752-1300-00V) is a prerequisite for the students who want to take this course. Equivalent course may be accepted; contact the instructor.
